2 results about "Nitinol SE" patented technology

Disclosed are example embodiments of a stent including a body formed of a nitinol wire material woven into a tapered shape. The body includes flared ends at both distal and proximal ends, with flare angles between 15 degrees and 30 degrees relative to a longitudinal axis of the stent. The body further includes a first portion having a first number of braid loops per unit length and a second portion having a second, lower number of braid loops per unit length, such that the first portion forms a tighter braid than the second portion. In the second portion, a wire segment of a braid loop is arranged at a shallower angle relative to the longitudinal axis compared to a wire segment of a braid loop in the first portion.

The present disclosure discloses a device including a proximal end, a distal end, a frame and a membrane. The frame is made of a plurality of members defining a single disc structure. The diameter of the frame increases from the proximal end to the distal end. Each member of the plurality of members includes a first portion disposed towards the proximal end defining a tubular profile, and a second portion disposed distal to the first portion and towards the distal end. The first portions of the plurality of members are at least partially coupled to each other. The membrane is disposed at least partially over at least one of an outer surface or an inner surface of the frame. The frame is made of a nitinol tube.
