System and method for cardiac valve repair

A cardiac valve repair implant, wherein the implant includes a central occluder, and frame and a thin sheet. The central occluder includes a central longitudinal axis. The frame extends proximally from the central occluder and is centered about and forms a circumference around the central longitudinal axis of the central occluder. The frame self-biases from a collapsed state to an expanded state. A proximal end of the frame projects proximally when the frame is in the collapsed state. The proximal end of the frame projects radially outward away from the central longitudinal axis of the central occluder when the frame is in the expanded state. The thin sheet is supported on a proximal portion of the frame. When the frame is in the expanded state, the thin sheet forms an annular surface defining an inner circular opening centered about the central longitudinal axis of the central occluder.

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.

ATRIOVENTRICULAR VALVE REPLACEMENT
20220015896 · 2022-01-20 ·

Apparatus and methods are described including a valve frame configured to support a prosthetic valve within a native atrio-ventricular valve. The valve frame includes an atrial part comprising a disc-shaped portion configured to be deployed on an atrial side of the valve annulus, and a frustoconical portion, and a cylindrical part to which the prosthetic valve leaflets are coupled. The cylindrical part configured to be deployed such that a ventricular end of the cylindrical part is disposed within the ventricle. A plurality of protruding struts are configured to protrude from outside the cylindrical part, the frustoconical portion of the atrial part being coupled to the cylindrical part via the protruding struts. Other applications are also described.

Staged deployment of expandable implant

An endoprosthesis delivery system includes an expandable endoprosthesis including a side branch portal, a first primary sleeve releasably constraining a proximal portion of the expandable endoprosthesis to a collapsed configuration, a second primary sleeve in parallel with the first primary sleeve, the second primary sleeve releasably constraining a distal portion of the expandable endoprosthesis to the collapsed configuration, and a secondary sleeve within the first primary sleeve. Upon release of the first primary sleeve, the secondary sleeve releasably constrains the proximal portion of the expandable endoprosthesis to a partially expanded configuration allowing access to the side branch portal via the partially expanded proximal portion of the expandable endoprosthesis.

Intraocular Artificial Lens Capsule
20210315687 · 2021-10-14 ·

An implantable artificial capsule and a method of implantation are provided. The implantable artificial capsule has a ring with a central opening to accommodate an intraocular lens and at least three haptic arms extending substantially orthogonal from the outer surface of the ring. Each arm has transcleral anchors for sutureless scleral fixation. Upon implantation of the implantable artificial capsule the arms are externalized trans-sclerally and atraumatically. The arms sit subconjunctivally. The implantable artificial capsule does not have any sutures for fixation and is suturelessly implanted in an eye, which is a major advantage as it significantly reduces complications during surgery and recovery.

Fiber-based surgical implant and method of manufacture

A fiber-based surgical implant stabilized against fraying, includes a thermally crimped flat-knitted fabric of a biocompatible, optionally biodegradable, polymer material having a glass transition temperature or other thermally induced secondary conformational mobility threshold in the temperature range of from 20° C. to +170° C. Also disclosed is a corresponding fabric and methods of producing the implant and the fabric.

TISSUE SPARING IMPLANT
20210290399 · 2021-09-23 ·

A femoral component of a hip implant, where the femoral component may be used specifically in a neck sparing resection and may include a shortened stem (with respect to a conventional stem) having a terminal flare portion for internally contacting a medial calcar portion of the proximal femur, and a significant curvature on its medial side. Other features of the femoral component include, flat side portions on the anterior and posterior sides of the stem, a lateral fin or a wing or T-back to aid in resisting torsional forces. The femoral component may also include a sagittal slot for proper fitting and placement in the femoral canal. The femoral component may also include a neck component that is modular with respect to the stem component. A head component, whether monoblock or modular with respect to the neck component, may also be utilized as part of the femoral component.

PROSTHETIC HEART VALVE

A prosthetic heart valve can include a radially expandable and compressible frame having an inflow end portion and an outflow end portion, the frame comprising a plurality of struts defining openings between them. The prosthetic valve can further include a valvular structure comprising a plurality of leaflets, each leaflet comprising a main body, opposing tabs on opposite sides of the main body, a coaptation edge portion, and a cusp edge portion. Each tab can be paired with an adjacent tab of an adjacent leaflet to form a plurality of commissures that are fixed relative to the frame, and each leaflet can have opposing edge portions between the opposing tabs and the cusp edge portion that are unattached to the frame, each unattached edge portion defining a gap that extends radially into the main body of the leaflet.

BIFURACTED FLOW DIVERTER SYSTEMS

One aspect of the invention provides a flow-diverting system including: a first stent having a proximal end, a distal end and a first sidewall opening; and a second stent having a proximal end, a distal end and a second sidewall opening. The first sidewall opening is of sufficient size for the distal end of the second stent to pass from inside the first stent through the first sidewall opening. The second sidewall opening is of sufficient size for fluid flow from inside the second stent through the second sidewall opening into the first stent.

Prosthetic valves with mechanically coupled leaflets

Described embodiments are directed toward centrally-opening leaflet prosthetic valve devices having a leaflet frame and a mechanically coupled leaflet. The described leaflet frames have projections that are configured to couple with a leaflet attachment region of a leaflet. Some embodiments include a leaflet retention feature that engages the leaflet frame projections and operates to secure the leaflet to the leaflet frame. Methods of making and using such prosthetic valve devices are also described.
