Abstract
A balloon catheter and stent delivery system for medical treatment of a patient are provided. The balloon catheter includes a hub, a shaft and a Y-shaped balloon. The Y-shaped balloon may include a first distal arm and a second distal arm having different diameters. The Y-shaped balloon may also include a first elongated balloon positioned or secured to a second elongated balloon to form the Y-shaped balloon. The first and second elongated balloons may be balloons having a circular profile at their distal end and a semi-circular profile at their proximal ends.
Claims12
A Y-shaped balloon for a balloon catheter, comprising:
- a first elongated balloon comprising a first semi-circular region over a first proximal end and a first circular region over a first distal end, the first circular region defining a first diameter;
- and
- a second elongated balloon comprising a second semi-circular region over a second proximal end and a second circular region at a second distal end, the second circular region defining a second diameter, with at least a portion of the first semi-circular region secured to at least a portion of the second semicircular region to form a circular proximal region.
A balloon catheter, comprising:
- a hub;
- a shaft comprising a proximal end and a distal end with the proximal end secured to the hub;
- and
- a Y-shaped balloon secured to the distal end of the shaft, the Y-shaped balloon comprising a proximal arm defining a proximal diameter, a first distal arm defining a first distal diameter, and a second distal arm defining a second distal diameter, where the proximal diameter and the second distal diameter are substantially equivalent and the proximal diameter is at least 1.2 times larger than the first distal diameter.
