Abstract
The present invention provides a catheter system which includes a catheter, an expandable balloon, at least one securement member, and a stent. The stent is disposed about the catheter and comprises at least one undulating band that extends circumferentially around the longitudinal axis of the catheter system. The undulating band includes interconnected strut members which form a series of alternating peaks and valleys. Adjacent strut members comprise a strut pair, wherein each strut member of the strut pair includes a protuberance positioned along the length of the strut member, between a peak and a valley. The protuberances, which are substantially circumferentially opposed to one another, engage a securement member, thereby minimizing lateral stent movement on the delivery system during delivery.
Claims19
A catheter system comprising:
- a catheter comprising a catheter shaft;
- an expandable balloon;
- at least one securement member, at least a portion of the securement member being engaged to an engagement region;
- and
- a stent having a longitudinal axis, the stent disposed about the catheter, the stent comprised of at least one undulating band extending circumferentially around the longitudinal axis, the at least one undulating band comprised of a plurality of interconnected strut members, each strut member having a length, the interconnected strut members forming a series of alternating peaks and valleys, at least two immediately adjacent strut members comprising a strut pair, each strut member of the strut pair comprising at least one protuberance, the at least one protuberance being positioned along the length of the strut member, between a peak and a valley, the protuberances being substantially circumferentially opposed to one another, the at least one securement member being engaged by each of the protuberances.
A catheter system comprising:
- a catheter comprising a catheter shaft;
- an expandable balloon;
- at least one securement member;
- and
- a stent having a longitudinal axis, the stent comprised of at least one undulating band extending circumferentially around the longitudinal axis, the at least one undulating band comprised of a plurality of interconnected strut members, each strut member having a length, the interconnected strut members forming a series of alternating peaks and valleys, at least two immediately adjacent strut members comprising a strut pair, each strut member of the strut pair comprising at least one protuberance, the at least one protuberance being positioned along the length of the strut member, between a peak and a valley, the protuberances being substantially circumferentially opposed to one another, the at least one securement member being engaged by at least two protuberances.
A catheter system comprising:
- a catheter comprising a catheter shaft;
- an expandable balloon, the expandable balloon disposed about the catheter, the expandable balloon comprising a first end, a second end, and a main body therebetween, the first end and second end engaged to the catheter shaft, a first end tapered region positioned between the first end of the balloon and the main body of the balloon, and a second end tapered region positioned between the second end of the balloon and the main body of the balloon;
- and
- at least one securement member engaged to the balloon.
