Abstract
Disclosed are implants, devices and systems capable of being deployed within the neurovasculature of a subject. The implants are configured for enhanced conformability to a vessel wall and have thromboresistant design features and coatings. The devices for implant deployment are configured for precise placement of an implant, resheathing of a partially deployed implant, and reliable detachment of an implant without distorting the positioning of the implant.
Claims36
A self-expanding thromboresistant intraluminal implant, the implant comprising:
- a generally tubular frame comprising:
- a proximal portion comprising a ring that extends along a circumference of the tubular frame, the ring comprising a plurality of ring struts, wherein adjacent pairs of ring struts join at a plurality of proximal apexes and a plurality of distal apexes to form a chevron pattern;
- a distal portion comprising a ring that extends along the circumference of the tubular frame, the ring comprising a plurality of ring struts, wherein adjacent pairs of ring struts join at a plurality of proximal apexes and a plurality of distal apexes to form a chevron pattern;
- and
- a central portion between the proximal portion and the distal portion, the central portion comprising:
- a plurality of longitudinally spaced apart rings that extend along the circumference of the tubular frame, each ring of the plurality of rings comprising a plurality of rings struts, wherein adjacent pairs of ring struts join at a plurality of proximal apexes and a plurality of distal apexes to form a chevron pattern, and
- a plurality of linking struts that extend at least partially along the circumference of the tubular frame, each linking strut of the plurality of linking struts connecting a distal apex of one ring of the plurality of rings to a proximal apex of an adjacent ring of the plurality of rings.

- wherein the tubular frame comprises a wall thickness of about 45 μm or less, and
- wherein the implant comprises a heparin coating.
