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

The present invention discloses a capsule endoscope with specific gravity control. The capsule endoscope comprises a housing to enclose various components, an inflatable device attached to a first longitudinal end of the capsule unit and an enteric coated shell attached to the first longitudinal end of the capsule unit to enclose the inflatable device between the enteric coated shell and the capsule unit. The various components include a camera sub-system for capturing image frames. The inflatable device comprises an inflatable membrane and an effervescent formulation inside the inflatable membrane. The enteric coated shell fits tightly onto the first longitudinal end of the capsule unit to prevent body liquid from leaking into a space between the enteric coated shell and the capsule unit when the capsule unit travels in human gastrointestinal tract after being swallowed.

Capsule enteric coating for controlling balloon expansion start time

An endoscopy capsule having an image collecting capacity includes a deformable member configured to inflate when exposed to body liquid. The deformable member includes an effervescent material. When the effervescent reacts with water the resulting Carbon-Dioxide gas reduces the specific gravity of the endoscopy capsule. The capsule is contained within a shell or dome when swallowed. The shell or dome is configured dissolve in either a low or high pH environment.

Capsule device having variable specific gravity

A coating formed of a substituted polycaprolactone and method of making and using the same are disclosed.

Substituted polycaprolactone for coating

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

The present invention provides an absorbable coating for an implantable device and the methods of making and using the same.

Absorbable coating for implantable device

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

Implantable medical devices fabricated from branched polymers are disclosed.

Implantable medical devices fabricated from branched polymers

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.
