Magnetic Beads for Reflux?



Gastroesophageal reflux disease (GERD) is considered to be a structural disorder. Usually the problem lies in the lower esophageal sphincter, that in certain patients is a little too loose at times, sending acidic stomach contents back up into the esophagus. The disease can lead to painful erosive esophagitis, or even serious conditions such as esophageal cancer.

A new clinical trial for the LINX Reflux Management System, a product of Torax Medical, Inc. (Shoreview, MN), is being conducted at selected U.S. and European centers. The device, described as a "bracelet" around the Lower Esophageal Sphincter composed of a series of miniature magnetic beads, can be implanted laparoscopically.

One of the hospitals in the United States, the UC San Diego Medical Center, is now actively participating in this early trial, as its press release testifies:

During a 20-30 minute minimally invasive surgical procedure, the device, made up of a series of magnetic beads, is secured around the bottom of the esophagus. Once in place, the magnetic attraction between the beads supports the valve to protect the esophagus from reflux, while still allowing it to open during swallowing or to release gas. Made of permanent rare earth magnets encased in titanium, the band is sized to fit each patient.

"With medical therapy alone, the production of acid in the stomach is suppressed, but the actual problem of reflux remains. The most appropriate long-term therapy for GERD is to restore the body's physiological barrier to correct the cause of reflux itself," said Horgan, the first surgeon in the western United States to implant the device in this clinical trial.

"I decided to participate in this clinical trial surgery because it may be a permanent, structural way of addressing the problem," said Gina Levine, age 43, who has suffered from GERD for more than 18 years. "I like the minimally invasive approach to this procedure and that it can be reversed if necessary."

And here's the information about the procedure, from a Torax Medical website:

The LINX™ procedure is performed by a surgeon using a minimally invasive surgical technique, called laparoscopy. The device is placed around the distal esophagus, just above the stomach, in the area of the Lower Esophageal Sphincter (LES).

Once the device is placed it will begin working immediately; magnetic attraction between the beads helps to keep the lower esophageal sphincter closed to prevent reflux, but will open to allow swallowing or the release of higher gastric pressures.

Following the procedure, under physician guidance, patients should be able to resume normal diet and will typically resume normal activities in less than a week.

Our guess is that the device will have to significantly outperform currently available therapies, such as open and Nissen fundoplications, before it is approved. But given the limited surgical therapeutic options nowadays, we really hope that the LINX Reflux Management System makes it through the trials and onto the surgical field.

For now, an empty trial page at ClinicalTrials.gov...

    A Tasmanian man, who lost his arm in a car accident, was told that he is a poor candidate for a prosthetic, since the amputation is too high for conventional devices. Being a rebel Aussie, Mark Lesek ignored the advice, and traveled to Sweden to implant a metal rod into his shoulder that can support a new prosthesis. The arm that he is now happily wearing is one he built with help from a business partner, and the project has developed further to include the University of Tasmania bioengineering team. The next step is to involve researchers that can help with lightening the unit using carbon fiber, and to create brain-computer interface to make the arm semi-autonomous.

    MAKO Introduces RIO Robotic Arm for Orthopedic Surgeries


    MAKO Surgical has announced the release of its RIO Robotic Arm Interactive Orthopedic System. On display at this week's American Academy of Orthopaedic Surgeons annual meeting in Las Vegas, the device is designed to assist surgeons during knee resurfacing operation, a minimally invasive type of surgery thought to be useful for younger, active patients with early osteoarthritis. Since the knee resurfacing is a notoriously difficult operation to perform, the hope is that such a robot will introduce stability and precision.

    From MAKO's press release:

    The RIO™ Robotic Arm Interactive Orthopedic System and the RESTORIS® MCK MultiCompartmental Knee System make bone and tissue sparing MAKOplasty® partial knee resurfacing available to a larger population of patients. Previously, it was only possible to perform this precision resurfacing surgery on the medial (inner) portion of the knee. Now it can be performed on the medial, patellofemoral (top) or both components of the knee, offering a large and growing population of patients with early to mid-stage osteoarthritis (OA) of the knee a less invasive treatment option than total knee replacement.

    “The field of medical robotics is coming of age, and MAKO is committed to leading the way in orthopedic surgery,” said Dr. Maurice R. Ferré, President, Chief Executive Officer and Chairman of the MAKO Board of Directors. “The advancement of our technology with RIO™ and RESTORIS® MCK allows a greater number of patients with osteoarthritis to benefit from the precision and improved outcomes of MAKOplasty®. ”

    MAKO’s robotic arm system is the first FDA-cleared robotic arm system for orthopedic surgery. It provides patient-specific, three-dimensional modeling for pre-surgical planning. As surgeons use the robotic arm to resurface the knee for placement of the implants, RIO™ provides real-time inter-operative visual, tactile and auditory feedback, enabling a high level of precision and optimal positioning of the implants.

    MAKOplasty® provides the potential for improved surgical outcomes, with a less invasive partial knee resurfacing procedure that spares healthy bone and tissue, preserves ligaments and allows for a more rapid recovery and a more natural feeling knee.

    Siemens Rolls Out 1.5 Tesla MRI for Breast Visualization


    Siemens is introducing an MRI machine, called Magnetom Espree-Pink, specifically designed for breast imaging. The 1.5 Tesla device features an innovative Sentinelle Vanguard Siemens' coil, and a 70cm bore size for those who are on the front lines of the obesity epidemic.

    From Siemens:

    The flexible "Sentinelle Vanguard for Siemens" coil solution makes both imaging and biopsies possible using only a single coil. Depending on requirements, only the lateral inserts of the coil are replaced. The frame itself remains on the table and does not have to be repositioned. In addition, due to its variable coil geometry (VCG), the coil can be optimally adapted to the different breast sizes of various patients. Excellent image quality is attained through an improved signal-to-noise ratio and with the help of eight RF channels.

    The new system additionally offers a comprehensive range of standard and advanced applications for breast imaging. These include, among others, the Breast Suite with Syngo Views for routine examination requirements, which can be used to obtain a three-dimensional representation of the breast with a high spatial and high temporal resolution in the sub-millimeter range, for instance. Syngo Grace is an application package for quantitative MR breast spectroscopy. This software can display the biomarker choline, thus providing valuable information on the biochemical composition of breast lesions. Syngo Blade is an application that ensures motion-free images, even when the patient moves during the examination.

    The workstation of the Magnetom Espree-Pink is equipped with the new syngo BreVis and syngo BreVis Biopsy software applications for planning and running the individual work steps during the image acquisition and biopsy processes. For example, syngo BreVis enables clinicians to prepare reports, calculate the size of a lesion, or compare MRI results with ultrasound or X-ray mammography images. The syngo BreVis Biopsy software application supports the physician in performing biopsies accurately and quickly using automatic calculations and pre-settings.

    The system is equipped with 18 channels, which ensures its investment security. The breast scanner can be upgraded to a Magnetom Espree with all imaging possibilities for any anatomical region, if required.

    CT-guided Placement of Microcoils Helps with VATS for Lung Nodules

    The Radiological Society of North America is reporting on new technology, developed at the University of British Columbia in Vancouver, that can guide the removal of small nodules within lungs. By preoperatively placing special fiber coated microcoils into the lung under CT guidance, a surgeon performing video-assisted thoracoscopic surgery (VATS) can remove a nodule with little damage to the surrounding tissue.

    From the press release:

    VATS is a minimally invasive technique in which one or more small incisions are made in the patient's chest and a small fiber optic camera and surgical instruments are inserted through the incisions. Images transmitted by the camera guide the physician through the procedure.

    VATS can replace a traditional thoracotomy, a surgical procedure that uses one larger incision to gain access to the chest. VATS typically results in less pain and faster recovery time for the patient compared to open surgery.

    Because small, peripheral lung nodules can be difficult to locate, physicians often have to resort to the more invasive thoracotomy procedure, removing larger amounts of lung tissue to successfully locate small nodules.

    For the study, Dr. Mayo and colleagues used CT-guided microcoil placement to assist in VATS removal of 75 small, peripheral lung nodules in 69 patients ranging in age from 31 to 81 years. Four patients had two nodules treated, and two of the patients had second nodules removed at a later date. In all, 75 procedures were performed. The microcoil technique allowed the researchers to locate 100 percent of small nodules, and 97 percent of the lung nodules were successfully and completely removed with VATS.

    The results show that with precise microcoil localization, even small nodules can be removed with VATS.

    "The real beauty of this procedure is that we are able to remove the entire nodule and very little surrounding tissue, so there is no decrease in lung function," Dr. Mayo said. "Recovery time is significantly reduced in these patients as a result. Instead of the three- to six-week recovery period that follows a thoracotomy, these patients can return to work within two to three days."

    RETISERT Eye Implant Prevents Lost Vision

    Sympathetic ophthalmia is an autoimmune condition thought to be caused when one eye is severely damaged, and the immune system overreacts and attacks the healthy eye, often leading to complete blindness. Until recently the common treatment option was oral steroids and immunosuppressive medication, but now clinicians at the University of Iowa are using a steroid releasing implant from Bausch & Lomb to prevent such a form of blindness.

    University of Iowa reports:

    The new Retisert treatment involves the surgical implantation into the endangered eye of a small plastic tab that contains a slow-release steroid called fluocinoloe acetonide. The insert provides immunosuppression only to the endangered eye, not other body parts. It lasts for about two-and-a-half years and then can be replaced.

    Along with UI retinal surgeons James Folk, M.D., professor of ophthalmology, and Karen Gehrs, M.D., clinical associate professor of ophthalmology, Mahajan published a retrospective paper online in January in the journal Ophthalmology that documents the successful use of Retisert to treat eight patients with sympathetic ophthalmia.

    The device previously was studied in approximately 300 individuals who had a different immune system inflammation of the eye. The UI-led sympathetic ophthalmia study found that with Retisert, the eight patients reduced or eliminated use of systemic medications to control inflammation. While two patients needed to resume using an oral immunosuppressive, vision improved or remained stable in all eight patients.

    "Using Retisert, we are stabilizing vision in patients with sympathetic ophthalmia and getting them off the heavy-duty immunosuppressive medications," Mahajan said. "Patients had been willing to put up with the serious side effects of systemic immunosuppression because if they lost vision in their remaining good eye, it would be totally life-altering. With Retisert, we can save the eye, and the side effects are limited to treatable risks of high pressure or cataracts in the eye."

    While each implant costs approximately $20,000, their use appears to be less expensive over the long run compared to systemic immunosuppressive drugs and the required frequent hospital visits.

    "If you add up the total number of patient visits, costs of lab tests and the costs of the immunosuppressive drugs, the $20,000 for the device is cheaper," Mahajan said.
