Bioabsorbable scaffolds having high crush recoverability, high fracture resistance, and reduced or no recoil due to self expanding properties at physiological conditions are disclosed. The scaffolds are made from a random copolymer of PLLA and a rubbery polymer such as polycaprolactone.

Shape memory bioresorbable polymer peripheral scaffolds

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.

Balloon expanded polymer stent

A medical device includes a polymer scaffold crimped to a catheter having an expansion balloon. The scaffold has a structure that produces a low late lumen loss when implanted within a peripheral vessel and also exhibits a high axial fatigue life. In a preferred embodiment the scaffold forms ring structures interconnected by links, where a ring has 12 crowns and at most two links connecting adjacent rings.

Methods for vascular restoration therapy

A method for manufacturing a shaping structure having a generally helical profile and configured to support electrodes for delivering electric energy into a cylindrical lumen of a patient. The method comprises providing a mandrel with a circular cylindrical shape and forming a first hole in the mandrel along the elongate axis, such that opposing ends of a bore of the first hole emerge at the proximal end and at the distal end; forming a second hole in the mandrel to extend from the curved surface to connect with the first hole; wrapping a metal wire around the mandrel; and inserting opposing ends of the metal wire into the second and the third hole respectively, and threading the opposing ends of the metal wire until they emerge from the opposing ends of the bore of the first hole; finally, heating the mandrel and the wire.

System for denervation

Method of manufacturing a shaping structure for denervation

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.

Method of crimping stent on catheter delivery assembly

A scaffold is formed by several segments joined or connected to each other by only at least one coupling. The coupling decouples the segments in the axial direction over a finite distance of axial displacement. The scaffold when implanted in a peripheral vessel reduces loading on rings of a segment due to the decoupling of the segments in the axial direction over the finite distance.

Coupled scaffold segments

A medical device includes a polymer scaffold crimped to a catheter having an expansion balloon. The scaffold, after being deployed by the balloon, provides a crush recovery of about 90% after the diameter of the scaffold has been pinched or crushed by 50%. The scaffold has a pattern including an asymmetric closed cell connecting links connecting the closed cells.

Crush recoverable polymer scaffolds

A method of manufacturing 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 marker support structures.

Method of making a stent

A medical device includes a polymer scaffold crimped to a catheter having an expansion balloon. The scaffold, after being deployed by the balloon, provides a crush recovery of about 90% after the diameter of the scaffold has been pinched or crushed by 50%. The scaffold also has a reduced crimped profile and a modification of the scaffold's ring structure at the crowns that contributes to the reduced crimped profile.

Polymer scaffolds having a low crossing profile

The present invention provides a semi-crystalline polymer for a coating on an implantable device for controlling release of drug and methods of making and using the same.
