AORTIC LANDING BAND SUPPORT METHOD AND SYSTEM
A method of providing support in an aortic region. The method includes wrapping a landing band around an outside of a portion of an aortic vessel in a vicinity of a sinotubular junction (STJ) to form a wrapped portion of the aortic vessel. The method further includes securing the landing band to form a secured landing band. The method also includes endovascularly delivering a stent graft in a radially constricted configuration into the aortic vessel. The method also includes deploying the stent graft to a radially expanded configuration such that the stent graft contacts the wrapped portion of the aortic vessel. The method also includes connecting the stent graft in the radially expanded configuration to the secured landing band.
Inflatable penile prosthesis with guides in valve of pump assembly
An inflatable penile prosthesis can comprise a reservoir, an inflatable member, and a pump assembly. The pump assembly can include at least one valve comprising an entry tube interface configured to attach to the entry tube and defining an entry passageway, an entry portion adjacent to the entry tube interface, a middle portion adjacent to the entry portion, an exit portion adjacent to the middle portion, the exit portion being narrower than the middle portion, the exit portion defining an exit portion passageway and comprising multiple guides extending toward a longitudinal exit axis, the multiple guides being symmetrical about the longitudinal exit axis, the exit tube interface adjacent to the exit portion, and a poppet disposed inside the chamber, the poppet being biased to rest against the entry portion.
Hybrid heart valves adapted for post-implant expansion
A hybrid prosthetic heart valve configured to replace a native heart valve and having a support frame configured to be expanded post implant in order to receive and/or support an expandable prosthetic heart valve therein (a valve-in-valve procedure). The prosthetic heart valve may be configured to have a generally rigid and/or expansion-resistant configuration when initially implanted to replace a native valve (or other prosthetic heart valve), but to assume a generally expanded form when subjected to an outward force such as that provided by a dilation balloon or other mechanical expander. An inflow stent frame is expandable for anchoring the valve in place, and may have an outflow end that is collapsible for delivery and expandable post-implant to facilitate a valve-in-valve procedure.
Intracardiac-Echocardiography-based Mitral and Trisucpid Replacement Valve
A method of constructing a replacement valve for repairing a heart having an annulus separating upstream and downstream regions. The method includes obtaining a representative perimetrical length of the annulus and fabricating a frame having a hub and legs extending outward from the hub to anchors axially offset from the hub. The method includes fabricating an annular band having a circumferential length corresponding to the representative length and attaching the band to the legs. The method includes forming a flexible component having a convex face having a margin and an axially offset region. And a concave face and connecting the offset region to the hub and portions of the margin to the band and/or a portion of the frame. The valve component moves to an open position when upstream pressure is greater than downstream pressure and to a closed position when downstream pressure is greater than upstream pressure.
STENT GRAFT WITH A LONGITUDINAL SUPPORT MEMBER
A delivery system for delivering and deploying stent grafts having a proximal stent includes a first lumen and a stent capture device including a capture portion fixedly connected adjacent a first lumen distal end. An outer catheter has a catheter distal end and a catheter inner diameter. A second lumen having a second distal end is slidably disposed about the first lumen and within the outer catheter. A stent graft sheath has a sheath proximal end connected to the second distal end and disposed about the first lumen. The sheath has a sheath distal end and a sheath inner diameter greater than the catheter inner diameter for holding a compressed stent graft. A distal nose cone has a cone proximal end connected to either the capture portion or the first distal end. The nose cone and the capture portion are movably adjustable to selectively capture the sheath distal end therebetween.
LANDING ZONE FOR ENDOVASCULAR PROCEDURES
Systems and methods for building a landing zone for an endovascular procedure are described. This procedure is “hybrid” in that it involves both direct access (e.g., sternotomy or partial sternotomy) to the site for installation of the landing zone, as well as endovascular installation of a TAVR or TEVAR device (e.g., stent graft) once the landing zone is installed. The landing zone is installed by wrapping a landing band around a portion of a vessel. The landing band may be selected to be fixed at a diameter so that it inhibits any expansion of the vessel, and also supports a later-installed TAVR or TEVAR device. The TAVR or TEVAR device is then endovascularly delivered to the vessel and deployed therein. The device expands until it contacts the vessel, which is supported from the outside by the landing band, which thus constrains and supports the device from outside.
Suturing thread for facelift and body lift
The present invention relates to a suturing thread for providing a more efficient lift procedure, and provides a suturing thread for a facelift and a body lift, wherein the suturing thread is made of a polymer material and has a plurality of conical protrusions or a plurality of funneled protrusions formed on an outer circumferential surface of a main thread of the suturing thread.
Systems and methods for providing penile modeling
A device for remodeling a penis, comprising a generally cylindrical hollow assembly having a lumen extending between proximal and distal ends, the distal end being in communication with the lumen to facilitate insertion of the penis into the lumen, the generally cylindrical structure having an interior surface facing the lumen and an exterior surface facing away from the lumen, a longitudinal direction and a transverse direction, the transverse direction being orthogonal to the longitudinal direction, the generally cylindrical assembly adapted to snugly and resiliently grip the penis, and includes an elastic fabric with one or more regions reinforced with a plastically deformable member.
Device for the delivery of a prosthetic implant and method of use thereof
A surgical device for assisting in the placement of a prosthetic implant. One or more sheets of polymer are in the form of a conical frustum such that a proximal end is sealed and a distal end is open, with an elongated slit extending from the distal end toward the proximal end. A single opening is formed by the distal opening and the elongated slit with a set of inter-lockable fastener elements disposed along opposing sides and configured to seal the elongated slit such that the distal end remains open to allow for egress of the prosthetic implant for placement into a surgical pocket. A lubricious coating is applied to the interior cavity of the frustum in addition to one or more surface active coatings. Movement of the prosthetic implant across the one or more surface active coatings causes the coatings to provide one or more offered benefits.
Dual-Layer Lumen Stent
A double-layer lumen stent (100) includes a main body lumen stent (10) and an outer-layer skirt stent (20) surrounding an outer wall of the main body lumen stent (10); the outer-layer skirt stent (20) includes a support structure (21) and a cover layer (22) arranged on the support structure (21); one end of the outer-layer skirt stent (20) is connected to the outer wall of the main body lumen stent (10); the other end of the outer-layer skirt stent (20) is an opening structure (24) composed of the support structure (21); and the cover layer (22) is formed into an oblique cut shape at an edge of the opening structure (24). In the double-layer lumen stent (100), when a clinician releases the double-layer lumen stent (100) at a human tissue such as a vessel through a delivery device, constraint from the cover layer (22) to the opening structure (24) of the outer-layer skirt stent (20) can be reduced, and the adhesion between the cover layer (22) at the opening structure (24) on the outer-layer skirt stent (20) and the main body lumen stent (10) is reduced, thereby reducing release resistance to the outer-layer skirt stent (20) during the release process of the double-layer lumen stent (100).
