The present embodiments provide systems and methods for treating a medical condition. In one embodiment, the system comprises a stent having proximal and distal regions, and further having a delivery state and an expanded state. A therapeutic agent is disposed on a segment of the stent. The stent is disposed around an exterior surface of a core assembly in the delivery state. A coupling assembly releasably secures the proximal region of the stent to the exterior surface of the core assembly. The coupling assembly secures the stent to the core assembly for a predetermined period while the stent is in the expanded state and during release of the therapeutic agent at a target site. The coupling assembly further enables the stent to be disengaged from the core assembly and deployed in a bodily passageway.

Detachable and retrievable stents for therapeutic agent delivery

The present invention relates to an adjustable length dilatation balloon catheter that includes a balloon catheter, a sheath that is slidably disposed around the balloon catheter, and an inverting tethering system that permits the selective adjustment of the exposed balloon length.

A suture passer includes a stylet and a cannula having an open distal end defining a cannula outer diameter. The stylet has a proximal segment configured for receipt within the cannula and including a suture retention notch, and a distal segment having an expanded outer diameter substantially matching the cannula outer diameter. The distal segment of the stylet terminates at a distal cutting edge. The suture passer includes a retracted position in which the proximal segment of the stylet is received within the cannula through the open distal end and a shoulder defining a transition between the proximal segment and the distal segment abuts the open distal end of the cannula, and an extended position in which the suture retention notch is distally disposed relative to the open distal end of the cannula.

In at least one embodiment, a catheter for insertion into a patient for providing treatment is provided. The catheter comprises an elongated shaft having a proximal portion extending to a distal portion. The proximal portion has a plurality of first lumens formed therethrough and at least one septum separating the first lumens in non-coaxial relationship with each other. The first lumens each have an associated flow area for providing the treatment through the proximal portion. The distal portion has a second lumen in fluid communication with the first lumens. The septum terminates distally in the proximal portion to merge the first lumens with the second lumen. The second lumen has a second flow area that is greater than any one of the associated flow areas of the first lumens for providing the treatment to the patient.

Multi-lumen catheter with increased flow area

A medical device delivery system has a tubular member defining a passageway and an inner member slideably disposed within the passageway. An expandable intraluminal medical device is disposed on a chamber of the inner member, and an evertable sleeve is attached to the inner member proximal to the chamber and to an inner surface of the tubular member. Relative movement between the tubular and outer members moves the evertable sleeve from a first position substantially overlying the expandable intraluminal medical device to a second position substantially proximal to the chamber.
