A length extensible implantable device includes a porous member and a longitudinal constraining member. The longitudinal constraining member can constrain at least a portion, up to the entire length of, the porous member in the longitudinal direction. The length of the longitudinally constrained portion can be expanded by applying force to the porous member. The porous member may be a porous tubular member.

The present invention is an anatomic system which uses the principle of applying higher elastic tonus than the rest tonus of the agonist muscles to provide the function of the antagonist muscles, and which is designed in a simplest way to provide the said purpose and which can be integrated to the body. The static mechanism of the invention is an elastic mechanism which applies a continuous stable tension in order to keep the joints open. The tension of the mechanism is calibrated by increasing or decreasing the amount of the liquid in a chamber which has flexible and elastic walls up to a certain via a port. In the dynamic mechanism of the invention, the tension applied by the elastic mechanism can be changed according to the motion the patient wants to perform.

A stent according to the invention includes: a strut extending in a predetermined direction; a first protrusion provided on the strut, the first protrusion being substantially L-shaped and extending in a direction away from the strut and in a direction toward a distal side in the predetermined direction; a second protrusion that is provided on the strut and located distal to the first protrusion, the second protrusion being substantially L-shaped, extending in a direction away from the strut and in a direction toward a proximal side in the predetermined direction, and having a tip spaced apart from a tip of the first protrusion; and an opaque member being substantially tubular and highly opaque to radiation, the opaque member having two end portions in which the first and second protrusions are inserted, respectively.

A device for inserting a pre-filled or silicone prosthesis into a surgical pocket is formed from a sleeve formed of a bottom layer and a top layer attached to the bottom layer along longitudinal edges of the bottom layer and top layer. The top layer has a greater width than the bottom layer so as to form a half-cylinder shape when the sleeve is filled. The sleeve has a constant cross-sectional area along a length of the sleeve. This device reduces the chances for the implant to rotate in an unintended manner due to the non-circular cross-section of the sleeve.

An endovascularly deployed prosthetic includes a portion for being positioned within an ascending aorta. The prosthesis includes a replacement aortic valve on a proximal end thereof. The prosthesis includes an increased diameter portion that seals against the aorta at a more distal portion, and a pair of conduits extend from the increased diameter portion to the coronaries for fluidly coupling the coronaries to the prosthesis.

A transcatheter aortic valve replacement (TAVR) device includes a paravalvular seal that includes outwardly extending fibers that create a seal with the aortic annulus when the TAVR is deployed.

A tendon repair implant for treatment of a partial thickness tear in the supraspinatus tendon of the shoulder is provided. The implant may incorporate features of rapid deployment and fixation by an arthroscopic means approach that compliment current procedures; tensile properties that result in desired sharing of anatomical load between the implant and native tendon during rehabilitation; selected porosity and longitudinal pathways for tissue in-growth; sufficient cyclic straining of the implant in the longitudinal direction to promote remodeling of new tissue to tendon-like tissue; and, may include a bioresorbable construction to provide transfer of additional load to new tendon-like tissue and native tendon over time.

A prosthetic heart valve (1) for implantation at the mitral annulus of a heart, the prosthetic heart valve comprising: a support framework (10) reversibly transformable between a collapsed configuration and an expanded configuration; and one or more leaflets connected to the framework; wherein, in the expanded configuration: the support framework defines a fluid pathway through the prosthetic heart valve, the fluid pathway having a portion with a D-shaped cross section for engaging the mitral annulus; and the one or more leaflets allow fluid to pass through the fluid pathway in a first direction but prevent fluid from flowing in the opposite direction.

This covered stent 100, which is released from a sheath 200 and placed in a lumen in a living body, is provided with: a tubular skeleton portion 11 which is stretchable in the axial direction and is expandable in the radial direction substantially perpendicular to the axial direction; and a stretch restriction portion 2 for restricting stretching of the skeleton portion in the axial direction. The stretch restriction portion is formed from a material different from that of the skeleton portion and restricts stretching of the skeleton portion in the axial direction when the skeleton portion is contracted in the radial direction while being stored in the sheath.
