A HUMAN IMPLANT ARRANGEMENT FOR CONSTRICTING A HUMAN TISSUE STRUCTURE
A human implant arrangement for permanently constricting a human tissue structure in a longitudinal direction. The human implant arrangement includes a longitudinal first anchoring part having lateral self-anchoring elements which have a first longitudinal anchoring orientation, a connection part which does not have anchoring elements, and a longitudinal second anchoring part which is connected in a longitudinal orientation to the longitudinal first anchoring part via the connection part. The longitudinal second anchoring part has lateral self-anchoring elements which have a second longitudinal anchoring orientation which is reverse to the first longitudinal anchoring orientation. A total length of the human implant arrangement is not larger than 40 mm.
Hair implants comprising enhanced anchoring and medical safety features
A hair implant includes: (a) a hair strand anchor including: an anchor body; at least one hair chamber disposed within the anchor body; and at least one tunnel through the anchor body, where the tunnel is free of a hair; and (b) at least one hair strand having a portion thereof retained in the at least one of the hair chamber; wherein the tunnel is configured to support collagen ligature growth after subcutaneous implantation by receiving and retaining collagen ligatures that anchor the hair implant to a hair implant recipient. Also disclosed is a hair implant including an anchor with first and second anchor bodies and at least one bridge connecting the anchor bodies and bridging at least one void between the anchor bodies, wherein the bridge supports and retains collagen ligature growth. One-piece implants are also disclosed, as are anchors, hair restoration and manufacturing methods.
Intra-aortic emboli protection filter device
An embolic protection device including a porous deflector screen including a filter, arranged to expand and to conform to a wall of the aortic arch covering entrances to arteries branching from an aorta, an emboli collector including a cylinder arranged to expand and to lie along walls of a descending aorta, pushing against walls of the descending aorta and anchoring the porous deflector screen, and a connecting portion for connecting the porous deflector screen and the emboli collector, arranged to push the porous deflector screen against a wall of the aortic arch while anchoring against the emboli collector. Related apparatus and methods are also described.
HAIR IMPLANTS COMPRISING ENHANCED ANCHORING AND MEDICAL SAFETY FEATURES
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 to anchor the anchor to a hair implant recipient, and the collagen receiving structure is free of hair. A fracture line in the anchor body allows the body to fragment, thereby releasing collagen ligatures and allowing the implant fragments to “release” and fall out of the skin. The at least one hair strand may comprise a primary hair element with emerging hair elements.
HAIR IMPLANTS COMPRISING ENHANCED ANCHORING AND MEDICAL SAFETY FEATURES
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 or 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 and alternatively wherein the at least one hair strand includes a bend, wherein the at least one collagen receiving structure, or the external surface feature, is configured to support collagen ligature growth after subcutaneous implantation of the hair implant so as to anchor the hair implant in the recipient. The hair implant includes a two-part construction having a base module formed of the anchor body and at least one hair stem configured for coupling with a long hair strand. Another hair implant alternative includes a hair strand having a first end that is passed through the skin, underneath and the up through the skin at another location to result in the hair strand having two portions projecting from the skin surface.

Also disclosed is a hair implant including an anchor with first and second anchor bodies and at least one bridge connecting the anchor bodies and bridging at least one void between the anchor bodies, wherein the bridge supports and retains collagen ligature growth. One-piece implants are also disclosed, as are anchors, hair restoration and manufacturing methods.
Radial expansion control mechanisms for intraluminal device
An intraluminal device and a method of removing a clot from a body lumen with an intraluminal device may be provided. The intraluminal device may include a hollow elongated shaft and a radially-expandable mesh segment situated distal to the elongated shaft. The elongated shaft may be secured relative to a first portion of the mesh segment. The intraluminal device may additionally include a core wire affixed to a second portion of the mesh segment and extending through the elongated shaft. The elongated shaft may be configured to radially expand the mesh segment by axially moving the first portion of the mesh segment relative to the second portion of the mesh segment. In addition, the core wire may be configured to radially expand the mesh segment by axially moving the second portion of the mesh segment relative to the first portion of the mesh segment.
Medical Device Delivery System and Methods of Delivering Medical Devices
In some embodiments, a medical device delivery system includes a catheter and a retainer. The retainer can be engaged with the medical device to restrain relative movement of the medical device in one or more axial and/or radial directions. A variety of retainers and retainer systems are disclosed, many of which can reliably disengage the medical device from the retainer. Methods for using the medical device delivery system are also described.
VENOUS VALVE PROSTHESES
A venous valve prosthesis includes a frame and a prosthetic valve coupled to the frame. With the venous valve prosthesis implanted in a vein, the prosthetic valve includes a closed configuration wherein an outer surface of the prosthetic valve is in contact with a wall of the vein around a circumference of the prosthetic valve to prevent blood from flowing past the prosthetic valve between the wall of the vein and the outer surface of the prosthetic valve. The prosthetic valve is configured to move to an open configuration such that at least a portion of an outer wall of the prosthetic valve partially collapses away from the wall of the vein in response to antegrade blood flow through the vein to enable blood flow between the outer surface of the prosthetic valve and the wall of the vein.
INTRAVASCULAR GUIDEWIRE FILTER SYSTEM FOR PULMONARY EMBOLISM PROTECTION AND EMBOLISM REMOVAL OR MACERATION
An intravascular emboli capture and retrieval system for intravascular embolism protection and embolism removal or maceration. Guidewire mounted proximally and distally located multiple opening filters are deployed within the vasculature and used to part, divide and macerate embolic debris and to capture such embolic debris within the confines thereof. A deployable flexible preformed memory shaped capture sleeve is alternatively used to collapse one or more filters and embolic debris therein for subsequent proximal withdrawal from the vasculature.
