    摘要： In accordance with the invention, there are provided medical devices with incorporated shape memory systems that allow a polymeric medical device to be inserted in a first conformation or configuration and revert to a second conformation or configuration. The invention is useful in allowing the easy insertion or implantation of a device followed by expansion of the device in order to be retained without expulsion from a body cavity, for example. In another aspect of the invention there is provided a medical device, such as a ureteral stent, that includes comprising an elongated member having a proximal end portion and a distal end portion joined by a body portion. The elongated member has an initial outer diameter. A retention construction serves for retaining the member within a bodily cavity. The member is formulated of a physiologically acceptable polymer capable of hydrating and expanding from the initial member outer diameter to form a final member outer diameter. The device can assume differing shapes and can exhibit different degrees of softening at different places along its length and possess shape memory so that it can be inserted in a first conformation or configuration and revert to a second conformation or configuration upon the occurrence of a triggering event such as hydration.

    摘要： Described herein are endoscopic plicators passed transorally into the stomach and used to plicate stomach tissue by engaging tissue from inside of the stomach and drawing it inwardly. In the disclosed embodiments, the tissue is drawn inwardly into a vacuum chamber, causing sections of serosal tissue on the exterior of the stomach to be positioned facing one another. The disclosed plicators allow the opposed sections of tissue to be moved into contact with one another, and preferably deliver sutures, staples or other means for maintaining contact between the tissue sections at least until serosal bonds form between them. Each of these steps may be performed wholly from the inside of the stomach and thus can eliminate the need for any surgical or laparoscopic intervention. After one or more plications is formed, medical devices may be coupled to the plication(s) for retention within the stomach.

    摘要： An apparatus is provided for facilitating substantially bloodless insertion into and withdrawal from a patient's body of a longitudinal member having a proximal end portion and having a distal end portion which is adapted to extend into the patient's body. The apparatus comprises a longitudinally extending sleeve having proximal and distal end portions and defining a lumen extending there along. The longitudinal member is positioned along the lumen. The sleeve has a line extending longitudinally along it which is either split or splittable so that the sleeve can be separated along the line for removal from about the longitudinal member while the distal end portion of the longitudinal member remains extended into the patient. A valve structure serves for preventing blood flow through the lumen. An access is present for allowing substantially bloodless insertion and withdrawal of the longitudinal member through the lumen.

    摘要： A method of controlling ablation volume depth includes providing a treatment apparatus. The apparatus comprises a housing having a proximal and distal end including a tissue contacting surface. The housing defines an interior with an energy delivery device positionable in the interior. The energy delivery device includes at least one electrode with a tissue penetrating distal end and is configured to be advanced from the interior into a target tissue site to define an ablation volume. An advancement device is coupled to the energy delivery device and is configured to advance the at least one electrode. The at least one electrode is advanced to a selected deployment depth beneath a tissue surface while avoiding a critical structure. Energy is delivered from the energy delivery device. An ablation volume is created at a controlled depth below the tissue surface responsive to the deployment depth while minimizing injury to the critical structure.
