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

A method of treating lower leg ischemia in a patient includes advancing a wire guide upstream through a vascular access sheath extending into an artery of the patient at a percutaneous entry point in the lower leg, and increasing a downstream flow of blood through the artery at least in part by dilating a constriction in the artery with a treatment mechanism guided into the constriction via the wire guide. A low profile balloon may be used as the treatment mechanism, and is advanced through the artery while the vascular access sheath protects the artery from irritation such that spasm of the artery is less likely to occur. Reduced risk of spasm advantageously enables retrograde access to chronic total occlusions such that multiple entry points into a patient's body are not necessary.

Catheter and treatment methods for lower leg ischemia

A variable length balloon catheter assembly and methods for inflating a variable length balloon to a predetermined length. The variable length balloon catheter has a balloon at a distal end and a plurality of stricture mechanisms securing the balloon to the catheter. The stricture mechanisms are provided at known intervals and have a known rupture pressure. The balloon is inflated and a known number of stricture mechanisms are ruptured providing for a variable balloon length based on the number of stricture mechanisms ruptured.

A balloon catheter is provided with three lumens. The first lumen may be used as a guide wire lumen. The second lumen may be used as an inflation lumen. The third lumen may be used to provide various treatments to a vessel. Methods of using the balloon catheter to treat a patient are also provided.
