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 coating device for coating a medical device with a drug-eluting material uses an in-process drying station between coats to improve a drug release profile. The drying station includes a heat nozzle configured for applying a uniform drying gas. A coating process using the dryer includes a closed-loop control for the gas between drying steps and an improved nozzle for producing more consistent spray patterns.

Drug-eluting coatings applied to medical devices by spraying and drying to remove solvent

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 medical device includes a polymer scaffold crimped to a catheter having an expansion balloon. A sheath is placed over the crimped scaffold after crimping to reduce recoil of the crimped polymer scaffold. The sheath is removed before the medical device is implanted within the body.

Sheaths used in polymer scaffold delivery systems

Catheter for delivery of a medical device such as a stent or filter includes an inner tubular member and an outer tubular member movable relative to the inner tubular member. The outer tubular member is disposed at the distal end of the inner tubular member. The inner tubular member includes a fluid lumen defined therein, the fluid lumen having a fluid flow port directed to the exterior surface of the inner tubular member. A pressure chamber is defined by the inner tubular member, the outer tubular member, a proximal seal and a distal seal, and is in fluid communication with the fluid flow port, wherein fluid introduced through the fluid flow port and into the pressure chamber applies a force on the proximal seal to move the outer tubular member in a proximal direction allowing the medical device constrained by the outer tubular member to be released.

Catheter having hydraulic actuator

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 braided polymeric scaffold, made at least in part from a bioresorbable material is deployed on a catheter that uses a push-pull mechanism to deploy the scaffold. A drug coating is disposed on the scaffold. A plurality of scaffold segments on a catheter is also disclosed.

Braided scaffolds

Various embodiments of methods and devices for drying coated stents in an oven are described herein.

Device for drying coated stents

A coating device for coating a medical device with a drug-eluting material uses an in-process drying station between coats to improve a drug release profile. The drying station includes a dryer having a telescoping plenum which provides a shield and drying region for the stent or scaffold to reside while a heated gas is passed over the stent/scaffold. The shield and drying region improve efficiency in drying, predictability or drug release rate, uniformity of coating material properties lengthwise over the stent/scaffold and provide a platform that can effectively support stents that are over 40 mm in length.

Dryers for removing solvent from a drug-eluting coating applied to medical devices

Segmented scaffolds composed of disconnected scaffold segments are delivered to an implant site on a delivery balloon. The segments are crimped to the balloon and separated from each other by gaps. When the balloon is inflated the gaps between the disconnected scaffold segments stay constant. Pillowed or banded balloons are used to deliver the segments.

Segmented scaffolds and delivery thereof for peripheral applications

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

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

Methods for making scaffolds for delivery via a balloon catheter are described. 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 structure has patterns that include an asymmetric or symmetric closed cell, and links connecting such closed cells.
