Abstract

An intravascular snare device for use in capturing debris found in blood vessels. The snare device is fabricated from a tube and includes longitudinally and circumferentially extending members. The snare device specifically embodies structure that provides enhanced radial opening and angular resistance to collapse.

Claims

1. A snare device for use in vasculature, comprising:

an elongate member having a first end and a second end, said second end extending exterior of the vasculature; and

a body configured to engage or capture material found in the vasculature, the body being manufactured from a tube and having generally circumferentially directed components and generally longitudinally directed components, said body being attached to said second end of said elongate member.

2. The device of claim 1, said body further comprising an open first end and a substantially closed second end.

3. The device of claim 2, wherein said elongate member extends from said open first end.

4. The device of claim 2, wherein said body has a longitudinal axis and is defined by a generally tubular sidewall, said elongate member extending from said sidewall in a parallel relationship with said longitudinal axis.

5. The device of claim 4, wherein said body has a compressed configuration and an expanded configuration, said elongate member being substantially removed from a path to said open end when said body is in at least its expanded configuration.

6. The device of claim 1, said body further comprising a first end portion, a second end portion and a midsection.

7. The device of claim 6, said first end portion of said body further comprising a plurality of apertures.

8. The device of claim 7, wherein said plurality of apertures include a generally diamond-shaped aperture configured between a first pair of spaced parallelogram-shaped apertures.

9. The device of claim 8, wherein said diamond-shaped aperture includes a first terminal end and a second terminal end, said elongate member extending from said first terminal end of said diamond-shaped aperture.

10. The device of claim 6, said second end portion of said body further comprising a plurality of apertures.
