Abstract
A filter system comprises an expandable filter, with a first end of the filter attached to an end of a first tube, and a second end of the filter attached to an end of a second tube. The tubes are arranged telescopically with respect to each other such that telescopic movement of the first and second tubes with respect to each other causes the filter to move between a first collapsed, position and a second expanded position, where the filter extends outwardly. The filter may be a folded-over member, when in the expanded position, or a spiraling member.
Claims22
A filter system comprising:
- a first tube;
- a second tube, the first tube and second tube moveable relative to each other in at least a partially telescoping arrangement;
- a filter, a first end of the filter supported by the first tube and a second end of the filter supported by the second tube, the filter moveable between a collapsed position when at least partially covered by the second tube, and an expanded position, when uncovered by the second tube;
- and,
- a delivery catheter for passage of instrumentation through the first tube to a predetermined site.
A filter system comprising:
- an outwardly expandable filter, a first end of the filter attached to an end of a first tube and a second end of the filter attached to an end of a second tube, the first and second tubes arranged telescopically with respect to each other such that telescopic movement of the first and second tubes with respect to each other causes the filter to move from a folded-over outwardly expanded orientation to an inverted orientation;
- and,
- a delivery catheter for passage of instrumentation through the first tube to a predetermined site.
The filter system of clam 19, wherein the first, second and third tubes are telescopically arranged with respect to each other.
