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 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. 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

Segmented scaffolds composed of disconnected scaffold segments with overlapping end rings are disclosed. Scaffolds with at least one discontinuous link are also disclosed.

Segmented scaffold designs

An implantable lumen filter is described. The filter may include a body formed from an elongate member. The body may include loops encircling an axis extending along the length of the body. The body may be sized to be implanted into a body lumen. The body may be capable of transitioning from a collapsed state to a deployed state. The filter may include a first group of a plurality of members positioned around at least one loop of said body. At least a portion of the plurality of members may be oriented towards the axis. The plurality of members may be arranged to capture and/or lyse particulates of a selected size and/or to inhibit the particulates from passing through the body. Methods to of making, deploying, and retrieving the same are described.

Methods and apparatus for filtering a body lumen

A bioabsorbable polymeric stent with time dependent structure and properties and methods of treating a diseased blood vessel with the bioabsorable polymeric stent are disclosed. The structure and properties of the stent change with time and allow the vessel to be restored to a natural unstented state. The bioabsorbable stent loses mechanical integrity in a controlled manner due to modification of selected structural elements.

Method of treatment with a bioabsorbable stent with time dependent structure and properties and regio-selective degradation

A device is provided that provides flexibility to an assembly. The device includes a loop hinge that hinges by twisting a body of the loop hinge.

An implantable lumen filter is described. The filter may include a body formed from an elongate member. The body may include loops encircling an axis extending along the length of the body. The body may be sized to be implanted into a body lumen. The body may be capable of transitioning from a collapsed state to a deployed state. The filter may include a first group of a plurality of members positioned around at least one loop of said body. At least a portion of the plurality of members may be oriented towards the axis. The plurality of members may be arranged to capture and/or lyse particulates of a selected size and/or to inhibit the particulates from passing through the body. Methods of making, deploying, and retrieving the same are described.

An expandable stent is implanted in a body lumen, such as a coronary artery, peripheral artery, or other body lumen. The stent includes a plurality of rings connected by links. The stent has a high degree of flexibility in the longitudinal direction, yet has adequate vessel wall coverage and radial strength sufficient to hold open an artery or other body lumen. The stent can be compressed or crimped onto a catheter to a very low profile since links are integrally formed from a portion of the struts forming the rings. The stent is constructed so that the cylindrical rings are very close together in order to provide maximum scaffolding, and if the stent has a drug coating, to provide a uniform drug delivery over the length of the stent. The connecting links are integrally formed from a portion of the struts forming the rings so that the links can have a maximum length thereby providing increased longitudinal flexibility of the stent.
