  • Thrombectomy Apparatuses
    Publication number: 20230414246
    Abstract: Medical devices and methods for using medical devices are disclosed. An example method of forming an expandable thrombectomy device includes disposing a scraping member along a mandrel, the scraping member including a proximal end region, a distal end region and a medial region positioned between the proximal end region and the distal end region. The method also includes constraining the proximal end region of the scraping member, constraining the distal end region of the scraping member and heat setting the scraping member.

  • Guidewire for crossing occlusions or stenoses having a shapeable distal end
    Patent number: 9254143
    Abstract: A hollow guidewire with a shapeable distal end, for removing tissue from a body lumen, such as a coronary artery. The hollow guidewire comprises an elongate, tubular guidewire body that has an axial lumen. A tissue removal assembly, such as a rotating drive shaft, is positioned at or near a distal end of the tubular guidewire body and extends through the axial lumen. Actuation of the tissue removal assembly removes occlusive material in the body lumen.

  • APPARATUS FOR CROSSING OCCLUSIONS OR STENOSES
    Publication number: 20080140101
    Abstract: A torqueable hollow device, such as a hollow guidewire device, with a pre-determined fixed distal tip is disclosed for removing occlusive material and passing through occlusions, stenosis, thrombus, plaque, calcified material, and other materials in a body lumen, such as a coronary artery. The hollow guidewire generally comprises an elongate, tubular guidewire body that has an axial lumen. A mechanically moving core element is positioned at or near a distal end of the tubular guidewire body and extends through the axial lumen. Actuation of the core element (e.g., oscillation, reciprocation, and/or rotation) creates a passage through the occlusive or stenotic material in the body lumen.
