Abstract

A device for use in capturing or collecting debris found in blood vessels or other body lumens. The devices can be fabricated from a tube and include longitudinally and circumferentially extending members. The device can further embody structure that provides enhanced radial opening and angular resistance to collapse and structure for absorbing or modifying forces applied thereto by an operator.

Claims

1. An intravascular device for use in a body lumen, comprising:

an elongate member having a first end portion and a second end portion, the first end portion configured to extend exterior of the body lumen; and

a body attached to the second end portion of the elongate member, the body being configured for deployment within the body lumen and including a substructure that absorbs forces applied to the body by the elongate member and a material collection body section, the substructure being separate and distant and longitudinally removed from the material collection body section to thereby substantially isolate the material collection body section and absorb bending and movement of the elongate member.

2. The device of claim 1, wherein the body has a proximal portion, a midsection and a distal portion, the proximal portion being attached to the elongate member.

3. The device of claim 2, the substructure further comprising a loop structure configured at the proximal portion of the body.

4. The device of claim 3, wherein the loop structure is defined by a plurality of rib members.

5. The device of claim 4, the proximal portion of the body further comprising a ring member attached to the loop structure.

6. The device of claim 2, the distal end portion of the body including a distal tapered section.

7. The device of claim 1, further comprising a filter extending along a length of the body, the filter including pores.
