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 stent that includes a plurality of quill filaments. Each quill filament includes filament material, a surface, and a plurality of quills. Each quill has a tip, a body, and a base where the body extends from the base to the tip. The quill filaments can be interwoven to form the stent or the quill filaments can be engaged to the framework of a stent.

A transcatheter atrio-ventricular valve prosthesis for functional replacement of an atrio-ventricular valve in a connection channel, having a circumferential connection channel wall structure, between atrial and ventricular chambers of a heart, including an inner device to be disposed in the interior of the connection channel, the inner device having a circumferential support structure which is radially expandable and having a valve attached to the circumferential support structure, and an outer device to be disposed on the exterior of the connection channel, wherein the outer device at least partly extends around the inner device at a radial distance to the inner device, wherein the inner and outer devices form a securing mechanism for securing the circumferential connection channel wall structure therebetween.

Medical appliances, such as stent grafts, may be formed of a cover and a scaffolding. The cover is composed of multiple layers of polymeric materials. A luminal layer is formed of rotational spun fibers of polytetrafluoroethylene. An abluminal layer is formed of expanded polytetrafluoroethylene. The scaffolding is disposed between the luminal layer and the abluminal layer. A cell impermeable layer is also disposed between the luminal layer and the abluminal layer. The cell impermeable layer is formed of an elastomeric material. The cell impermeable layer is impervious to cell migration across the layer when the stent graft is in a nominal state and in an expanded state. The stent graft is free of pleats or wrinkles when the stent graft is in the nominal state and in the expanded state.

Disclosed herein are elastic, bioresorbable encasements for medical implants, methods for making the same and uses thereof.

A suspension liner has a liner body portion, a textile material, and a plurality of seals formed along a length of the suspension liner toward a closed distal end and protruding circumferentially about a liner profile. Each seal has a same shape including a peak having a rounded profile and a width narrowing toward the peak and defines a sealing surface arranged to form a secure interface with an interior wall of the socket that retains the suspension liner within the prosthetic socket. The textile material is located intermediate interior and exterior surfaces of the suspension liner that formed of one or more silicone materials in the area of the seals and the textile material defines the exterior surface of the suspension liner proximal and distal to the seals.

A composite scaffold having a highly porous interior with increased surface area and void volume is surrounded by a flexible support structure that substantially maintains its three-dimensional shape under tension and provides mechanical reinforcement during repair or reconstruction of soft tissue while simultaneously facilitating regeneration of functional tissue.

A method for treating an intestine with an expandable scaffolding expanded within the intestine. After placing the expandable scaffolding at a target location, such as across a fistula, the first and second end portions of the expandable scaffolding are radially expanded such that the first and second end portions contact an inner surface of the intestine on opposing sides of the fistula, anchoring the first and second end portions to the intestine. Radially expanding the first and second end portions foreshortens the medial portion along the longitudinal axis such that the first and second end portions are drawn closer together along the longitudinal axis as the medial portion foreshortens to close the fistula.

The present invention relates to a method for integrating an electronic circuit in or on a medical stent. The method comprises obtaining (101) a deformable medical stent (21) in a substantially planar shape, in which the deformable medical stent is adapted for being deployed in a substantially cylindrical shape in the body. The method also comprises attaching (104) a deformable electronic circuit (22) onto the deformable medical stent in the planar shape thereby forming a deformable hybrid structure. The method also comprises shaping (107) said hybrid structure into the cylindrical shape.

A medical device may include an implantable device for treating a body tissue structure. The implantable device may include a wire structure which may include a wave pattern. The wire structure may be elastic so as to provide a pressure around the body tissue structure such that the pressure may change with movement of the body tissue structure.
