An implant material having an implant surface comprising a plurality of tissue-contacting members arranged in a regular or irregular two-dimensional array, each tissue-contacting member having a convex curved tissue-contacting surface. Methods of preparing and using such implant materials.

A breast biopsy marker includes a catheter shaft and a bioabsorbable balloon. The catheter shaft has a lumen, a proximal tube portion, and a distal tube portion. The proximal tube portion is joined to the distal tube portion by a frangible link. The distal tube portion has a one-way valve located in the lumen. The bioabsorbable balloon is fixedly connected to the distal tube portion to define a balloon assembly. The bioabsorbable balloon is configured for fluid communication with the lumen of the catheter shaft at a location distal to the one-way valve of the distal tube portion of the catheter shaft. The balloon assembly is configured to be separated from the proximal tube portion of the catheter shaft by breaking the frangible link.

The present disclosure relates generally to stents, systems, and methods for gastrointestinal treatment. In some embodiments, a stent may include a tubular scaffold having a first end opposite a second end, wherein a lumen extends between the first and second ends. The tubular scaffold may include a flared section and a medial section extending from the flared section, wherein a first diameter of the flared section is greater than a second diameter of the medial section. The stent may further include a liner extending partially along a surface of the tubular scaffold, wherein the liner is spaced from an anchoring region of the flared section to promote tissue ingrowth with the flared section.

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.

According to an aspect, a penile implant includes a first member having a coupling portion and a locking portion and a second member having a coupling portion and a locking portion The coupling portion of the first member is configured to engage the coupling portion of the second member to movably couple the first member to the second member such that the first member is configured to be placed in a first position with respect to the second member and a second position with respect to the second member. The locking portion of the first member is configured to engage the locking portion of the second member help retain the first member in its second position with respect to the second member.

Devices for assisting with the functioning of a tricuspid valve of a heart include a shaft, a flow optimizer, and an anchoring mechanism. A tilting mechanism can be configured to tilt the shaft relative to a central axis of the anchoring mechanism. Leaflets (e.g., multi-layer leaflets) of the flow optimizer can include a membrane and a rim, and the rim can have a higher stiffness than the membrane.

A mechanical prosthetic heart valve having a ring, multiple hinges, and multiple leaflets. The hinges are attached to the ring and are evenly spaced from one another along the inner circumference of the ring. Each leaflet is rotably attached to a hinge by an opening located in the center of the lower portion of the leaflets. The ring can include multiple protrusions located along the inner circumference of the ring. The protrusions of the ring limit the opening angle of the leaflets. By limiting the opening angle of the leaflets, wear and tear of the hinges and leaflets, as well as the probability of malfunction of the mechanical prosthetic heart valve are reduced. In addition, limiting the opening angle of the leaflets may increase the opening and closing speed of the leaflets, thus improving performance of the mechanical prosthetic heart valve when the patient is experiencing an elevated cardiac frequency.

The invention provides a device for treating urinary incontinence having a fillable expandable balloon made of a flexible material. The wall of the balloon has at least one recess and a valve. A central core located in the lumen of the balloon encloses a central channel having one or more openings and one or more magnetable elements there being.

A stent for repairing post-anastomasis (e.g., bariatric) surgery leaks is formed by an elongated tube having a proximal flare-shaped flange, an enlarged middle section, and a distal flare-shaped flange, where an exterior surface of the elongated tube is substantially covered with a polymer.

Tissue engineering devices and methods employing scaffolds made of absorbable material for use in the human body for tissue genesis and regenerative and cellular medicine including breast reconstruction and cosmetic and aesthetic procedures and supplementing organ function in vivo.
