  • BALLOON EXPANDED POLYMER STENT
    Publication number: 20220226133
    Abstract: A stent made from a material comprising a polymer is disclosed. The stent has a pre-crimp diameter and a wall thickness such that a ratio of the pre-crimp diameter to the wall thickness is between 30 and 60. The stent has a pattern of interconnected elements. The interconnected elements including a plurality of rings connected by links, wherein each ring includes struts and crowns, and the struts are configured to fold at the crowns when the stent is crimped to the balloon.

  • Balloon expanded polymer stent
    Patent number: 11324614
    Abstract: A medical device includes a polymer stent (or scaffold) crimped to a catheter balloon. The stent, after being expanded from a crimped state by the balloon, provides a crush recovery of about 90% of its expanded diameter after being pinched or crushed by an amount equal to about 50% of the expanded diameter. The stent has a pattern including a W-shaped or W-V shaped closed cell and links connecting the closed cells.

  • Method of crimping stent on catheter delivery assembly
    Patent number: 10123894
    Abstract: A method of crimping a stent is disclosed. The stent includes a minimum crimped diameter such that in the minimum crimped diameter, a pair of stent rings, between which marker support structures reside, do not make contact with the marker support structures. The crimped profile of the stent of the present invention can be as small as the crimped profile of a same stent but without the maker support structures.
