Abstract:
Medical devices and methods for making and using a medical device are disclosed. An example medical device may include an implantable medical device. The implantable medical device may include a stent having a covered portion and an uncovered portion. The covered portion may be releasably attached to the uncovered portion. A cover member may be disposed along the covered portion. The uncovered portion may include a release tab that is designed to release the uncovered portion from the covered portion. A removal member may be coupled to the covered portion for aiding in the removal of the covered portion from an implantation site.
Abstract:
A pancreatic stent includes a main body convertible between a compressed configuration for delivery and an expanded configuration once deployed, the main body including an inner surface defining a stent lumen and an outer surface. A plurality of drainage features are formed within the outer surface of the main body, the plurality of drainage features permitting placement of the pancreatic stent within a patient's pancreas without blocking side branches of the pancreas.
Abstract:
A medical device may include an expandable energy delivery array reciprocally movable between a first configuration and a second configuration. The expandable energy delivery array may include a first assembly having a first proximal end piece, a first distal end piece, and one or more first energy transfer elements extending between the first proximal and first distal end pieces, and a second assembly having a second proximal end piece, a second distal end piece, and one or more second energy transfer elements extending between the second proximal and second distal end pieces. The second proximal end piece may be proximal to the first proximal end piece and the second distal end piece may be distal to the first distal end piece.
Abstract:
Devices, systems, and methods for facilitating access to the pancreaticobiliary system are disclosed. In particular, the present disclosure relates to devices used to apply suction to the papilla, e.g., duodenal tissue surrounding the papilla, to facilitate cannulation to reach the bile duct and/or pancreatic duct. Devices may include a suction cup or an endoscope cap configured to apply suction to a tissue surface.
Abstract:
A system for treating tissue includes a first anchoring device including a first anchoring element at a distal end thereof for anchoring the first anchoring device in a first target portion of tissue extending about a periphery of a tissue defect to be treated and a first suture receiving feature at a proximal end thereof. The system also includes a second anchoring device including a second anchoring element at a distal end thereof for anchoring the second anchoring device in a second target portion of tissue about the periphery of the tissue defect and a second suture receiving feature at a proximal end thereof. Furthermore, the system includes a suture configured to be passed through the first and second suture receiving features such that a tension applied to the suture draws the first and second anchoring devices toward one another to close the tissue defect.
Abstract:
A needle for collecting a tissue sample includes a needle body extending longitudinally from a proximal end to a distal end and including a channel extending therethrough and a plurality of optical fibers extending along a length of the needle body and configured to pass laser energy therethrough to the distal end of the needle body to cut and collect a tissue sample within the channel.
Abstract:
The medical device (200) may include an elongate member (202) having a proximal end and a distal end, and a plurality of legs (212) coupled to the distal end of the elongate member. The medical device may also include a moveable element (210) distal to the distal end of the elongate member, disposed around the plurality of legs. The moveable element may be reciprocally moveable relative to the elongate member and plurality of legs between a first and second position. The plurality of legs may be in a collapsed configuration when the moveable element is in the first position, and may be in an expanded configuration when the moveable element is in the second position.
