    摘要： To increase the resistance to liquid and substance flow through a lumen of a tubular organ, a cuff comprising a flexible, mesh base member is appended to an exterior wall of the tubular organ such that it only partially surrounds the tubular organ. Ultimately, tissue ingrowth through the mesh base member integrates the cuff into the wall of the tubular organ. When the cuff is applied to the urethra of an incontinent patient, the increased resistance to flow renders the patient continent while still allowing normal voiding. The base member may also support an optional expandable component, e.g., a balloon-like element that can be selectively inflated and/or deflated to restrict the lumen of the tubular organ by a desired degree.

    摘要： Absorbable implants for breast surgery that conform to the breast parenchyma and surrounding chest wall have been developed. These implants support newly lifted breast parenchyma, and/or a breast implant. The implants have mechanical properties sufficient to support a reconstructed breast, and allow the in-growth of tissue into the implant as it degrades. The implants have a strength retention profile allowing the support of the breast to be transitioned from the implant to regenerated host tissue, without significant loss of support. Three-dimensional implants for use in minimally invasive mastopexy/breast reconstruction procedures are also described, that confer shape to a patient's breast. These implants are self-reinforced, can be temporarily deformed, implanted in a suitably dissected tissue plane, and resume their preformed three-dimensional shape. The implants are preferably made from poly-4-hydroxybutyrate (P4HB) and copolymers thereof. The implants have suture pullout strengths that can resist the mechanical loads exerted on the reconstructed breast.

    摘要： In one embodiment, the present invention provides a prosthesis that can be implanted within a heart to at least partially block gaps that may be present between the two mitral valve leaflets. In one preferred embodiment, the prosthesis includes an anchoring ring that expands within the left atrium to anchor the prosthesis and a pocket member fixed to the anchoring ring. When the mitral valve is open, blood flows past the pocket member, maintaining the pocket member in a collapsed state. When the mitral valve closes, the backpressure of the blood pushes into the pocket member, expanding the pocket member to an inflated shape. The mitral valve leaflets contact the expanded pocket member, allowing the prosthesis to block at least a portion of the openings between the leaflets, thereby minimizing regurgitated blood flow into the left atrium.
