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.
Claims20
A method of forming an expandable thrombectomy device, the method comprising:
- 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;
- constraining the proximal end region of the scraping member;
- constraining the distal end region of the scraping member;
- and
- heat setting the scraping member.
A method of forming an expandable thrombectomy device, the method comprising:
- disposing a plurality of braided wires along a mandrel, the plurality of braided wires including a proximal end region, a distal end region and a medial region positioned between the proximal end region and the distal end region;
- constraining the proximal end region of the plurality of braided wires;
- constraining the distal end region of the plurality of braided wires;
- and
- heat setting the plurality of wires.
A scraper device, comprising:
- a handle;
- an outer shaft having a proximal end region coupled to the handle, a distal end region and a lumen extending therein;
- an inner shaft extending through the lumen of the outer shaft, the inner shaft having a proximal end region and a distal end region, wherein the proximal end region is coupled to the handle;
- and
- an expandable scraping member having a proximal end region attached to the proximal end region of the outer shaft, a distal end region attached to the distal end region of the inner shaft and a medial region positioned between the distal end region and the proximal end region;
- wherein the scraping member is configured to shift between an unexpanded configuration and an expanded configuration;
- wherein the medial region defines an expansion point of the scraping member.
