Abstract
A medical device includes a sheath having a lumen and an elongate member disposed within the lumen of the sheath. The elongate member is moveable relative to the sheath and includes a retrieval assembly. The retrieval assembly has a collapsed position within the lumen of the sheath and an expanded position when extended beyond a distal end of the sheath. The elongate member defines a lumen configured to receive a laser.
Claims29
A medical device, comprising;
- a sheath having a lumen;
- an elongate member disposed within the lumen of the sheath and moveable relative to the sheath, the elongate member including a retrieval assembly having a collapsed position within the lumen of the sheath and an expanded position when extended beyond a distal end of the sheath, wherein the retrieval assembly includes a plurality of legs;
- a laser disposed within a lumen of the elongate member, the laser and the elongate member being moveable relative to each other;
- and
- wherein the elongate member defines an inner surface angled relative to a longitudinal axis of the elongate member to direct the laser at a predetermined angle relative to the longitudinal axis of the elongate member.
2 more elements
A medical device, comprising:
- a sheath including a lumen, a first opening on a distal most end of the sheath, a second opening on a side surface of the sheath at a distal end of the sheath, and an inner surface proximate the second opening to direct a laser through the second opening;
- and
- an elongate member disposed within the lumen of sheath and moveable relative to the sheath, the elongate member including a retrieval assembly having a collapsed position within the lumen of the sheath and an expanded position when extended beyond the first opening of the sheath.
