The template further includes a plurality of substantially straight elongated chordae portions each having a proximal end connected to the distal edge of one of the at least two leaflet portions and a distal end extending therefrom and one or more papillary muscle head portions formed at a commissure between distal ends of at least two of the plurality of chordae portions. A total width of the leaflet portions of the template is substantially equal to a circumference of a native annulus of a heart valve.

PROSTHETIC HEART VALVE

A system can include a delivery catheter comprising a balloon and an implantable prosthetic heart valve. The prosthetic valve can have a plastically expandable and compressible unitary frame comprising a plurality of circumferentially extending rows of angled struts, including first, second, and third rows of angled struts forming rows of diamond-shaped cells, and a valvular structure comprising a plurality of leaflets. A cusp edge portion of each leaflet is connected to the frame by a skirt that is disposed between the frame and the cusp edge portions, the skirt being sutured to selected struts of the frame along diagonal paths extending from an inflow end portion toward an outflow end portion. Each diagonal path along which the skirt is sutured to the frame extends along the first, second, and third rows of angled struts.

PROSTHETIC HEART VALVE

A system can include a delivery catheter comprising a balloon and an implantable prosthetic heart valve. The prosthetic valve can have a plastically expandable and compressible unitary frame comprising first, second, and third rows of angled struts that define two circumferentially extending rows of diamond-shaped cells that extend continuously around the frame, and a valvular structure comprising a plurality of leaflets. A cusp edge portion of each leaflet is connected to the frame by a skirt that is connected to and disposed between the frame and the cusp edge portions of the leaflets, the skirt being connected to consecutive struts in the first, second, and third rows of struts with sutures. The compressed prosthetic heart valve can be mounted around the balloon and radially expanded to the expanded configuration with the balloon inside a patient's body.

STENT-GRAFT PROSTHESIS WITH PRESSURE RELIEF CHANNELS

A stent-graft prosthesis for implantation within a body vessel includes a graft material, a frame, and a channel. The graft material includes a proximal end, a distal end, and a graft lumen extending between the proximal and distal ends. The frame is coupled to the graft material. The channel is configured to relieve pressure associated with pulsatile blood flow during implantation of the stent-graft prosthesis within a body vessel. The channel permits blood to flow from an upstream side of the stent-graft prosthesis to a downstream side of the stent-graft prosthesis when the stent-graft prosthesis is in a partially expanded configuration in the body vessel. The channel may be a plurality of channels.

Manually adjustable device

Devices, systems and methods for altering functioning of a tissue/organ by application of force thereto. In one preferred embodiment, a device for reducing or preventing regurgitation of blood through a valve of a heart is provided. A device may include a main body having a segment adapted to apply force to a surface of tissue/organ; a member that applies counterforce to the force applied by the segment; and an adjuster that is manually operable to change the force applied by the segment. The adjuster can be manually operated before or after anchoring of the device to the tissue/organ.

Vocal fold prosthesis and method for removal of laryngeal web
11406492 · 2022-08-09 ·

Typically, surgical intervention is required to remedy abnormalities of the vocal cords. However, surgical intervention often causes a laryngeal web, or glottic web, to form which impairs the sound quality of the vocal cords. The prosthesis and methods of the invention effectively eliminate regrowth of a laryngeal web after surgery over all other prior art devices and methodologies. During the operative procedure, the prosthesis may be inserted through a surgically created hole in a laryngeal web allowing a laryngeal bridge to assist in holding the prosthesis in position. Following surgery, after the vocal cords heal, the prosthesis may then be removed, and the laryngeal bridge also removed. In the case of an anterior procedure, the prosthesis produces a sharp anterior commissure without any glottic web. The prosthesis and method greatly reduce the recurrence of a laryngeal web.

BREAST RECONSTRUCTION IMPLANT

Absorbable implants can be used to create volume and shape in the breast of a patient with regenerated tissue. The implants comprise scaffolds formed from layers of parallel filaments. The layers of filaments can be stacked and bonded together to form scaffolds with porous crisscross arrangements of filaments. The implant's scaffolds may be coated or filled with cells and tissues, including autologous fat graft, and/or a vascular pedicle may be inserted into the implant. The implants are particularly suitable for use in plastic surgery procedures, for example, to regenerate or augment breast tissue following mastectomy or in mastopexy procedures, and can provide an alternative to the use of permanent breast implants in these procedures.
