摘要： The present disclosure provides apparatus and methods for removing thrombus outside of a hemodialysis. The hemodialysis catheter comprises an elongate shaft comprising a plurality of lumens. A first lumen has a first distal port. The first lumen is configured for the flow of a fluid in a first direction. A second lumen has a second distal port proximal to the first distal port. The second lumen is configured for the flow of the fluid in a second direction opposite to the first direction. A third lumen has a third distal port proximal to the second distal port. An elongate device is disposed through the third lumen. The elongate device has an operable member on a distal end or a device to connect to an operable member disposed on the elongate shaft. The operable member is configured to engage and remove thrombus from an exterior surface on the elongate shaft.

摘要： An aneurysm closure clip along with a system and method for use by a physician in delivering the closure clip into the vasculature of a patient is disclosed. The closure clip delivery system comprises a delivery tube in the form of a catheter, a guide wire, and a detachable closure clip. The closure clip includes a proximal side and a distal side. The distal side comprises at least two winged elements that interact with the wall of the body vessel to hold the clip in place after delivery. The proximal side includes a seal element and a guide bar. The guide bar is in communication with the guide wire during delivery. The seal element forms a barrier between the aneurysm and the rest of the body vessel, thereby, reducing any pressure exerted on the aneurysm. The seal element and optionally the winged elements include a material layer comprised of bioremodelable material, such as an extracellular matrix material (ECM).

摘要： A method of puncturing an interatrial septum between a right atrium and a left atrium may include introducing a distal end of a catheter endoluminally into the right atrium. The method also may include introducing a distal end of a cannula into the right atrium. The cannula may include a proximal first segment and a distal second segment. The distal second segment may be deflectable away from a linear configuration relative to the proximal first segment. A needle tip may be provided at a distal end of the distal second segment. At least a portion of the cannula may be received within a lumen of the catheter. The method also may include deflecting the distal second segment in the right atrium to a deflected configuration by actuating a mechanism at a proximal end of the cannula to align the needle tip with a target point on the interatrial septum.

摘要： Among other things, embodiments of a retaining mechanism for holding a portion of the suture of a suture anchor are disclosed. When a suture anchor is inserted into a patient, the portion of the suture extending from the body is held in tension by a two-piece snap-fit mechanism. One piece has a base with an extending shaft portion and a bulbous head, and a lumen runs through the shaft. The second piece has a hole or space for snapping the second piece onto the first piece. The extending portion of the suture runs through the lumen in the first piece and can be wrapped around the shaft. Snapping the second piece onto the first contains the suture and prevents loss of tension in it.

摘要： A prosthesis system for repair of a transected body vessel is provided. The system can include first and second prostheses each including a tubular graft body and a support structure. Each prosthesis can be expandable between a compressed and an expanded configuration. In the expanded configuration, outer surfaces of the first and second prostheses can engage walls of the body vessel. The system can include a sleeve member formable into a tubular body. The first and second prostheses can be coupled to one another at a joint to form a coupled prosthesis. The sleeve member can receive the coupled prosthesis and cover the joint to inhibit leakage therefrom. The prosthesis system can connect first and second portions of the body vessel to permit blood flow therethrough. The sleeve member can be discrete to the coupled prosthesis or can have one end fixedly attached to the coupled prosthesis.
