Abstract
Expandable emboli filter and thrombectomy devices adapted for use with microcatheters to remove debris from blood vessels. The devices embody expanded profiles that span the entirety of various sized target vessels and thus are particularly effective in the engagement of debris found in vessels.
Claims27
An expandable device for treating blood vessels, comprising:
- an elongate member having a distal end portion;
- a loop formed from a member entwined about itself or at least two members entwined about each other to form a twined configuration;
- the loop affixed to the distal end portion;
- and
- a filter device, the filter device affixed to the loop.
An expandable device for repairing blood vessels, comprising:
- an elongate member having a distal end portion;
- a first loop and a second loop, each of the first and second loops being affixed to the distal end portion of the elongate member, the second loop being distal to the first loop;
- and
- a plurality of connecting fibers extending between the first and second loop.
An expandable device for repairing blood vessels, comprising:
- an elongate member having a distal end portion;
- a first loop and a second loop, each of the first and second loops being affixed to the distal end portion of the elongate member, the second loop being distal to the first loop;
- and
- a plurality of connecting members extending between the first and second loop;
- wherein the connecting members comprise a single member routed between the first and second loops.
An expandable device for repairing blood vessels, comprising:
- an elongate member having a distal end portion;
- a first loop and a second loop, each of the first and second loops being affixed to the distal end portion of the elongate member, the second loop being distal to the first loop;
- a third loop configured between the first and second loops, the third loop adapted to provide medial support;
- and
- a plurality of connecting members extending between the first and second loop.
An expandable device for repairing a blood vessel, comprising:
- an elongate member having a first stop and a second stop positioned distal to the first stop;
- a generally tubular elongate member positioned coaxially about the elongate member and the stops, the tubular elongate member having a distal end portion;
- an expandable basket affixed to the distal end portion, the basket having a terminal end;
- and
- a slidable member positioned about the elongate member and between the first and second stops, the slidable member affixed to the terminal end;
- wherein the slidable member and the tubular elongate member are separate whereby the slidable member and tubular elongate member are displaceable relative to one another so as to increase or decrease the diameter of the basket.
An expandable device for repairing a blood vessel, comprising:
- an elongate member having a first stop and a second stop positioned distal to the first stop;
- a generally tubular elongate member positioned coaxially about the elongate member and the stops, the tubular elongate member having a distal end portion;
- an expandable basket affixed to the distal end portion, the basket having a terminal end;
- and
- a slidable member positioned about the elongate member and between the first and second stops, the slidable member affixed to the terminal end;
- wherein the basket is defined by helically routed wire elements, the wire elements having proximal and distal portions, the distal portions being more stiff than the proximal portions.
