  • Patent number: 9480776
    Abstract: Provided are medical devices for implantation in patients having suffered the loss of or damage to at least part of their esophagus. The medical device connects the esophagus or remaining part thereof with the stomach to form a gastro-esophageal junction that promotes healing and encourages new host tissue growth while distributing the load and decreasing tension at the anastomotic site. The medical device comprises extracellular matrix shaped into a conformation that more closely approximates the geometry of the native gastro-esophageal junction than does direct attachment of the stomach to the shortened esophagus. Molds useful in manufacturing the medical device and methods of use of the device are also described herein.

  • Publication number: 20150297885
    Abstract: Implantable electrical stimulation leads for the treatment of biological conditions include a lead body with an electrical connector at one end and multiple in-line electrodes at the other end. The lead body has a length ranging from 350 mm to 630 mm to allow for implantation from an incision site further removed from the final positioning site of the electrodes. One lead has a suture loop extending from the most distal electrode for pulling the lead through the working channel of an endoscope. Another lead has a length of suture with a free end attached to the most distal electrode. Yet another lead has a length of suture attached to the most distal electrode at one end and a needle at the other end. The needle has a curve designed to facilitate maneuvering in confined anatomy. The lead having the needle is designed to be implanted laparoscopically.

  • Publication number: 20060075963
    Abstract: An apparatus for seeding material in a scaffold member capable of entrapping such seeding material therein is provided. The apparatus may include a chamber having an interior and capable of maintaining a negative pressure and capable of enclosing the scaffold member therein, and a support member for rotating the scaffold member disposed within the interior of the chamber and for introducing the seeding material into the chamber. At least a portion of rotating the scaffold member occurs simultaneously with applying the negative pressure condition to the scaffold member. The seeding material may be passed from the interior of the scaffold member to the exterior of the scaffold member in response to the application of negative pressure such that at least of portion of the seeding material is entrapped in the scaffold member.
