A hybrid medical device that can aid in reconstructive or augmentative surgery of the breast is disclosed. The device can utilize a suitable biological collagen tissue matrix combined with a synthetic material, for example, that can impart a high initial strength to the repair site while permitting proper healing and revitalization of the implanted device.

At least a portion of fabrics for use in medical devices is formed from polymeric materials. The fabrics may be uncoated, partially coated or fully coated with one or more layers of a polymer. The fabrics may be used for the leaflets and/or cuffs of prosthetic heart valves and as a component of other medical devices.

The disclosure provides example apparatus and methods. One example apparatus includes a first woven stent having a curved form in an expanded state. In the expanded state, at least a first portion of the first woven stent has a weave pattern arranged along an outer curvature of the first woven stent that is different than a weave pattern arranged along an inner curvature of the first woven stent. And the first woven stent is biased toward the curved form due to shape memory.

The invention discloses an implant. The implant may include a first flap and a second flap. The first flap may further include a first portion, a second portion and a transition region. The first portion may be configured to be attached proximate a sacrum. The second portion may be configured to be attached to an anterior vaginal wall. The transition region lies between the first portion and the second portion. The second flap may be fabricated such that a portion of the second flap is configured to be attached to a posterior vaginal wall. The implant may be configured such that a value corresponding to a biomechanical parameter defining a biomechanical attribute of the portion of the first flap attaching to the anterior wall is different from a value of the biomechanical parameter defining the biomechanical attribute of the portion of the second flap attaching to the posterior wall.

A method for filtering particulate matter from a blood vessel in a patient, including inserting a device into the blood vessel, the device including at least an outer structure capable of insertion into the blood vessel; and an inner filter anchored to the outer structure, the inner filter having a one-way valve though which a medical instrument may be passed.

Systems and methods introduce and deploy prosthesis into a blood vessel or hollow body organ by intra-vascular access. The prosthesis is secured in place by fasteners which are implanted by an applier that is also deployed by intra-vascular access. The applier is configured to permit controlled, selective release of the fastener in a step that is independent of the step of implantation.

A device for treatment of valve regurgitation is described, comprising frameworks (114, 133, 141, 701, 812, 821, 911) and an anchoring unit (132). The anchoring unit (132) is connected to the frameworks (114, 133, 141, 701, 812, 821, 911); the frameworks (114, 133, 141, 701, 812, 821, 911) can be expanded and compressed and have an inflow end (421) and an opposite outflow end (422); valve leaflets (142, 621, 721, 751) capable of opening and closing in blood flow are provided inside the frameworks (114, 133, 141, 701, 812, 821, 911); the anchoring unit (132) can keep the frameworks (114, 133, 141, 701, 812, 821, 911) in an expanded state at the orifice position of a natural heart valve. The device for treatment of valve regurgitation and an implantation method therefor can effectively treat valve regurgitation.

A device includes a first end portion, a second end portion, an intermediate portion, and a graft material. The first end portion has a first end diameter. The second end portion has a second end diameter smaller than the first end diameter. The first end portion comprises a first material. The second end portion comprises a second material different than the first material. The intermediate portion is between the first end portion and the second end portion. The intermediate portion tapers between the first end portion and the second end portion. The graft material is coupled to at least the intermediate portion.

A device for treating regurgitation of a tricuspid valve (4) is disclosed. The device comprises a tricuspid valve plug (21) capable of compressing and expanding and a tricuspid valve plug fixing device used for anchoring the tricuspid valve-in-plug (21) to an orifice of the tricuspid valve (4). The tricuspid valve plug (21) is provided with an inflow end (42, 52) and an opposite outflow end (47, 57), and a prosthetic valve (50, 70) capable of being opened and closed is disposed in the tricuspid valve plug (21). When the tricuspid valve (4) is dosed, the prosthetic valve (50, 70) is automatically closed, and when the tricuspid valve (4) is opened, the prosthetic valve (50, 70) is automatically opened.

A device includes a first end portion, a second end portion, an intermediate portion, and a graft material. The first end portion has a first end diameter. The second end portion has a second end diameter smaller than the first end diameter. The first end portion comprises a first material. The second end portion comprises a second material different than the first material. The intermediate portion is between the first end portion and the second end portion. The intermediate portion tapers between the first end portion and the second end portion. The graft material is coupled to at least the intermediate portion.
