A delivery tool includes a delivery capsule, disposed at a distal portion of the tool. The delivery capsule includes a proximal capsule-portion dimensioned to house a first part of an implant, and a distal capsule-portion dimensioned to house a second part of the implant; and an extracorporeal control portion, disposed at a proximal portion of the tool, the control portion including one or more controllers and one or more locks. The controllers are operatively coupled to the proximal and distal capsule-portions such that the proximal and distal capsule-portions are movable with respect to the implant via actuation of the controllers. The tool has sequential states in which movement of the proximal and distal capsule-portions is variously inhibited or facilitated.

An expandable mechanical device for use during a thrombectomy medical procedure having enhanced visibility during imaging. Furthermore, the configuration of the eyelet and/or strut optimizes retention of the marker in the eyelet during the medical procedure without increasing overall profile of strut.

A flow reducing implant for reducing blood flow in a blood vessel having a cross sectional dimension, the flow reducing implant comprising a hollow element adapted for placement in the blood vessel defining a flow passage therethrough, said flow passage comprising at least two sections, one with a larger diameter and one with a smaller diameter, wherein said smaller diameter is smaller than a cross section of the blood vessel. A plurality of tabs anchor, generally parallel to the blood vessel wall, are provided in some embodiments of the invention.

A vascular graft suitable for implantation, and more particular to a vascular graft having an expandable outflow region for restoring patency of the graft after implantation into a body lumen.

A biodegradable in vivo supporting device is disclosed. In one embodiment, a coated stent device includes a biodegradable metal alloy scaffold made from a magnesium alloy, iron alloy, zinc alloy, or combination thereof, and the metal scaffold comprises a plurality of metal struts. The metal struts are at least partially covered with a biodegradable polymer coating. A method for making and a method for using a biodegradable in vivo supporting device are also disclosed.

A stent design reduces the likelihood of contact among structural members when the stent diameter is reduced before insertion into the body. In one approach, an undulating link has a J-shaped profile or has an angled portion on one side at the peak of the link, in order to reduce contact during crimping. The stent may also include structural features that improve such aspects as flexibility, the coatibility of a drug coating onto the stent, flare reduction, stent retention within the body and/or reduction of the minimum diameter of the stent during crimping.

A stent that includes a stent body, which includes a strut formed from a cylindrical base material. The strut possesses a manufactured minimum outer diameter when the strut is formed from the cylindrical base material. The stent body is configured to be compressed onto an outer surface of an expandable member of a catheter. The stent body is configured to be expanded radially outward by applying a nominal pressure directed by a manufacturer within the expandable member. The strut possesses an expanded outer diameter when the stent body is expanded by the expandable member at a pressure which is two atm lower than the nominal pressure. The manufactured minimum outer diameter of the strut is equal to or larger than expanded outer diameter of the strut when the stent body is expanded by the expandable member at the pressure which is two atm lower than the nominal pressure.

A stent delivery system includes an elongated shaft, a balloon and a stent. The balloon is dilatable from a contracted position to an expanded position when a fluid flows into an interior of the balloon. The stent is formed by wires that are spaced apart so that at least one gap is formed between the wires. The stent is mounted on the outer surface of the balloon when the balloon is contracted. The balloon includes a protruding portion which protrudes radially outward through the gap of the stent when the stent is mounted on the balloon and the balloon is in the contracted position. A lubricant is disposed on the outer surface of the balloon at least on a part of the protruding portion of the balloon, and an other portion of the balloon covered by the stent does not have the lubricant.

A biodegradable stent that is degraded in a living body includes a stent body that is made of a biodegradable material and is deformed to have an expanded diameter in the living body; and a biodegradable drug-coating portion formed on the stent body. The drug-coating portion is degraded, in an expansion retention period during which an expansion retention force (radial force) of the deformed diameter-expanded stent body that acts on an inner wall of a lumen thereof is maintained, and before 60% of a degradation period from indwelling of the stent body in the living body to complete degradation thereof elapses.

Methods are disclosed including thermally processing a scaffold to increase the radial strength of the scaffold when the scaffold is deployed from a crimped state to a deployed state such as a nominal deployment diameter. The thermal processing may further maintain or increase the expansion capability of the scaffold when expanded beyond the nominal diameter.
