11344448 · 2022-05-31 · ·

Described herein are devices and methods for treating eye conditions. Described is an ocular implant including an elongate member having an internal lumen forming a flow pathway, at least one inflow port communicating with the flow pathway, and at least one outflow port communicating with the flow pathway. The elongate member is adapted to be positioned in the eye such that at least one inflow port communicates with the anterior chamber, at least one outflow port communicates with the suprachoroidal space to provide a fluid pathway between the anterior chamber and the suprachoroidal space when the elongate member is implanted in the eye. The elongate member has a wall material imparting a stiffness to the elongate member. The stiffness is selected such that after implantation the elongate member deforms eye tissue surrounding the suprachoroidal space forming a tented volume.

Shape memory bioresorbable polymer peripheral scaffolds

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.

Balloon expanded polymer stent

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.

PROSTHESIS
20220133467 · 2022-05-05 ·

Described is a prosthesis for implantation beneath the skin of a subject, the prosthesis comprising a support structure of super elastic material (e.g., nitinol), wherein the support structure is sized and shaped for augmenting, replacing, or reconstructing tissue of the subject, such as the breast. In certain embodiments, the prosthesis further includes an elastomeric outer shell having a cavity therein, the outer shell being sized and shaped for augmenting or replacing, for example, breast tissue of the subject; wherein the support structure is disposed within the cavity of the elastomeric shell.

Replacement Cardiac Valves And Methods Of Use And Manufacture

Prosthetic mitral valves and their methods of manufacture and use.

Three-dimensional woven fabric implant devices

A docking device includes a hollow cylindrical body portion having an internal surface and an outer surface. The hollow cylindrical body portion is formed of a three-dimensional (3D) woven fabric comprising a plurality of different types of fibers.

AUXETIC STENTS FOR MANAGING VENOUS STENOSIS

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.

Methods and apparatus for endovascular heart valve replacement comprising tissue grasping elements

A method for endovascularly replacing a patient's heart valve including the following steps: endovascularly delivering an anchor and a replacement valve supported within the anchor to a vicinity of the heart valve in a collapsed delivery configuration, the anchor having grasping elements adapted to grasp tissue in a vicinity of the heart valve; expanding the anchor, thereby rotating the grasping elements; and grasping the tissue with the rotating grasping elements.

Radially collapsible frame for a prosthetic valve and method for manufacturing such a frame

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 (10, 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).

THREE-DIMENSIONAL (3D) HERNIA PLUG DEVICE AND A METHOD OF MANUFACTURING THEREOF

Various embodiments are disclosed herein that generally relate to a three-dimensional (3D) hernia plug device and a method of manufacturing thereof. In at least one embodiment, there is disclosed a three-dimensional (3D) hernia plug, comprising: a waist portion extending, along a longitudinal extension axis, between a first waist end and a second waist end; one or more first overhangs coupled to the first waist end; and one or more second overhangs coupled to the second waist end, wherein the hernia plug is configured to translate between a pre-activation state and a post-activation state.
