A method for repairing a defective heart valve includes directing a delivery catheter to form a first curve around the heart valve at a first side of the heart valve leaflets and forming a second curve of the delivery catheter around the heart valve on a second side of the heart valve leaflets. The first and second curves are connected through a commissure of the heart valve and an annuloplasty implant is ejected from the delivery catheter while the delivery catheter is retracted such that the annuloplasty implant is arranged along the first and second curve.

A system and method for a stent delivery system, the delivery system having a catheter and a balloon coupled to a distal portion of the catheter. The catheter with the radially expandable member is inserted into a cavity in a mold. Heat and pressure are applied for a period of time which inflates the balloon and imparts a shape memory to a portion of the balloon. The balloon is removed from the cavity of the mold with a shape memory.

Embodiments of the disclosure concern devices comprised of resorbable, shape-memory foam configured to allow for healing at a desired location. In particular embodiments, use of the device at the location utilizes the inherent environment at the location to allow expansion of the device, resulting in an improved fit for the device. In specific cases, the device is a vaginal stent configured for use for pediatric or adolescent populations.

Prosthetic mitral valves and their methods of manufacture and use.

A system of prosthetic implants for a total knee replacement procedure is provided. The system includes a tibial component of a knee joint implant, a tibial insert configured to be positioned against the superior side of the platform of the tibial component, a first femoral component of a knee joint implant, and a second femoral component of a knee joint implant.

The present invention relates to a radially collapsible frame (1) for a prosthetic valve, the frame (1) comprising an outflow end region (3) at a proximal end of the frame (1) and an inflow end region (2) at a distal end of the frame (1), opposite to the outflow end region (3). The frame (1) further includes at least two radially spaced commissure attachment regions 910, 10, 10) and a cell structure (30), composed of a plurality of lattice cells being arranged radially around a flow axis of the frame (1) and connecting the at least two commissure attachment regions (10, 10, 10). Finally, at least one anchoring/positioning arch (20, 20, 20) is provided, wherein said at least one anchoring/positioning arch (20, 20, 20) radially overlaps the cell structure (30) at least partially. In order to form the Inventive frame from as a single piece, the invention further relates to a method comprising bending the at least one anchoring/positioning arch (20, 20, 20) towards the cell structure (30) of the frame (1).

Disclosed examples generally relate to a fabric-like smart hernia plug and method of using thereof. In some examples, the hernia plug comprises an expandable mesh portion formed of a smart memory alloy (SMA), wherein the mesh portion is transformable between a compressed pre-activated state and an expanded post-activated state, the mesh portion comprising a plurality of open cells surrounded by struts formed of the SMA.

A stent for insertion into a vessel of a patient includes an inner tube comprising a positive Poisson's ratio (PPR) material and defining a lumen extending along a longitudinal axis of the stent; and an outer tube comprising a negative Poisson's ratio (NPR) foam material and disposed around an entirety of the inner tube, the outer tube extending along the longitudinal axis of the stent. The stent is configured to exhibit an auxetic behavior in response to a deformation of the stent. An outer surface of the second portion is configured to apply a pressure to an inner surface of the vessel when the stent is implanted into the vessel and the deformation is removed.

A fixture includes a first ring member and a second ring member. The first ring member has a first open center and has a first tool connector disposed at a first radial position relative to the first open center. The second ring member has a second open center coupled to the first ring member at a joint. The joint is disposed at a second radial position relative to the first open center. The joint has a second tool connector. The joint is configured to enable movement of the first ring member relative to the second ring member.

Stents useable for treating venous stenosis are disclosed. In embodiments, a stent is configured to be auxetic, expanding axially as it is expanded radially, to prevent the imposition of tension on portions of a blood vessel adjacent to the stented portion of the blood vessel, and thereby prevent a narrowing of the adjacent portions and improving luminal gain. The stent may include one or more cross members that are deformable axially, to allow the axial length of the stent to be adjusted while maintaining a constant diameter, and further to allow the stent to be curved to conform to vessel curvature.
