An apparatus includes a delivery catheter having a deployable dynamic valve that dynamically opens and closes in response to relative fluid pressure thereabout, particularly while in an anatomical lumen. The valve is maintained in a collapsed configuration during introduction to a treatment site. The valve is adapted to automatically move from the collapsed configuration to a deployed configuration at the treatment site.

A delivery assembly includes a prosthetic device, a catheter shaft, a release wire, a first line, and a second line. The prosthetic device has a first arm and a second arm. The release wire extends through the catheter shaft. The first line includes a first loop. The first line extends from the catheter shaft, through the first arm of the prosthetic device, and to the release wire, where the release wire extends through the first loop. The second line includes a second loop. The second line extends from the catheter shaft, through the second arm of the prosthetic device, and to the release wire, where the release wire extends through the second loop.

A mastopexy implant for maintaining the breast in an elevated and aesthetically pleasing position includes a lower pole support comprising end portions which may be affixed to the chest wall or to a previously installed upper suspension strut. The implant is loaded in an insertion device. The insertion device is inserted through a small incision and into a subcutaneous pocket created in an inferior half of the breast. The lower pole support may have various constructs and in one embodiment includes a unitary conformable mesh having a plurality of arm or band members which are attached across the breast parenchyma and to the chest wall.

A surgical apparatus for treating a vessel blockage in a vessel of a patient having an elongated member having an outer wall, a first hole at a distal portion and a second hole spaced proximally from the first hole positioned in a side wall. A first lumen is provided within the elongated member for blood flow through the second hole, through the lumen and exiting the first hole to maintain blood flow during treatment of the vessel blockage. A motor driven impeller is rotatable during blood flow through the first lumen to enhance blood flow as blood flows into the second hole positioned proximal of the vessel blockage and exits the first hole distal of the vessel blockage during injection of fluid through one or more openings to treat the vessel blockage.

A hair implant suitable for subcutaneous implantation is provided having an anchor comprising an anchor body, and at least one collagen receiving structure selected from the group consisting of at least one tunnel disposed through the anchor body and an external surface feature of the anchor body. The anchor further comprises at least one hair strand projecting from a distal end of the anchor body, wherein the at least one collagen receiving structure is configured to support collagen ligature growth after subcutaneous implantation of the hair implant so as to anchor the anchor to a hair implant recipient, and the collagen receiving structure is free of hair.

A filter configured to be disposed within the vasculature to capture or trap material within a body lumen is disclosed. The filter may be configured to be removable and may be configured to slice through ingrown or encapsulated tissue during removal. A filter deployment device or system which may be configured to deliver a filter or filters to a position within a body lumen, such as within the vasculature, is also disclosed. The filter deployment device may be configured to limit inadvertent decoupling of a filter. Also, the filter deployment device may be configured to retrieve a deployed filter.

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.
