Abstract
The invention relates to a system for dilatation of a body passage and delivery of a stent into the body passage of a patient, and related methods of using such a system. The dilatation and stent delivery system may comprise a dilatation catheter having an expandable member on a distal end, and a stent delivery catheter configured to retain a stent and deliver the stent to a body passage. The stent delivery catheter defines a lumen sized to receive the dilatation catheter and permit movement of the dilatation catheter relative to the stent delivery catheter.
Claims19
A system comprising:
- a first catheter, the first catheter comprising a first expandable member;
- a second catheter, the second catheter comprising:
- an inner shaft, the inner shaft comprising a stent retaining region, the inner shaft defining a lumen sized to receive the first catheter and to permit movement of the first catheter relative to the second catheter;
- an outer sheath, the inner shaft positioned within a lumen defined by the outer sheath, the outer sheath having a cross-sectional size;
- a first tip, the first tip comprising a first portion, the first portion having a first cross-sectional size at least as large as the cross-sectional size of the outer sheath.
A catheter system comprising:
- a tubular member, the tubular member having a cross-sectional size;
- a first shaft, at least a portion of the first shaft positioned within a lumen defined by the tubular member;
- a second shaft, at least a portion of the second shaft positioned within a lumen defined by the first shaft;
- and
- a third shaft, at least a portion of the third shaft positioned within a lumen defined by the second shaft, the third shaft comprising a tip, wherein at least a portion of the tip has a cross-sectional size at least equal to the cross-sectional size of the tubular member.
A catheter system comprising:
- a tubular member, the tubular member having a cross-sectional size;
- a first shaft, at least a portion of the first shaft positioned within a lumen defined by the tubular member, the first shaft having a tip, at least a portion of the tip has a cross-sectional size at least equal to the cross-sectional size of the tubular member;
- and
- a second shaft, at least a portion of the second shaft positioned within a lumen defined by the first shaft.
