Abstract
A catheter system comprises a catheter having an elongate catheter shaft such that a portion of the catheter shaft proximal a stent retaining region defines at least one bend that is bent around the longitudinal axis of a vessel. The catheter also has a side branch guidewire housing, defining a side branch guidewire lumen, and a side branch guidewire that extends through the side branch guidewire lumen.
Claims20
A catheter system comprising:
- a catheter shaft including a proximal region, a distal region and a longitudinal axis, the catheter shaft defining a primary guidewire lumen configured to receive a primary guidewire;
- a balloon disposed about the distal region of the catheter shaft;
- and
- a side branch guidewire housing attached to the balloon, the side branch guidewire housing defining a side branch guidewire lumen, the side branch guidewire housing comprising at least a portion that extends at an oblique angle away from the balloon, wherein the side branch guidewire housing further comprises an expandable centering band, the centering band being disposed around the at least a portion of the side branch guidewire housing extending at an oblique angle away from the balloon, the centering band having an expanded state and an unexpanded state.
