Abstract: Ultrasound probe systems and methods for using an ultrasound probe to assist during treatment of conditions of the human heart are provided. The method may comprise loading a medical instrument into a guide fastened to the ultrasound probe. The ultrasound probe may be inserted into a patient by way of an incision. The distal end of the ultrasound probe may be navigated to a location adjacent to an exterior surface of the heart. A treatment site may be identified on the exterior surface of the heart based on images obtained from an ultrasound transducer disposed within a distal end of the ultrasound probe. The medical instrument may be advanced within the guide to the treatment site and the medical instrument used for treatment. After treatment, the medical instrument may be withdrawn from the treatment site.

Abstract: A prosthetic valve has an annular frame including a plurality of strut members that is radially collapsible to a collapsed configuration and radially expandable to an expanded configuration. A leaflet structure is situated at least partially within the frame. The leaflet structure includes a plurality of leaflets, each leaflet having opposing commissure tab portions on opposite sides of the leaflet. Each commissure tab portion is paired with an adjacent commissure tab portion of an adjacent leaflet to form a commissure. The commissure tab portions of each leaflet are folded to form a plurality of layers positioned on the inside of the frame. A reinforcement member is positioned between the layers of each commissure tab portion.

Abstract: 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.

Abstract: A prosthetic heart valve can include a radially expandable and compressible frame having an inflow end, an outflow end, and a plurality of struts. The prosthetic valve can further include a valvular structure comprising a plurality of leaflets, each leaflet comprising a coaptation edge portion and a cusp edge portion. The cusp edge portion of each leaflet can be folded toward the outflow end of the frame along a bending axis and a reinforcing member extends along an outflow surface of the cusp edge portion along the bending axis. The prosthetic heart valve can include a plurality of connecting skirts, each disposed between the cusp edge portion of an adjacent leaflet and the frame. First stitching secures the reinforcing member and the connecting skirts to the cusp edge portions and second stitching secures the connecting skirts to selected struts of the frame.

Abstract: 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.

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.

Abstract: An anchoring system and related methods are provided for treatment of dilated hearts and of functional valve regurgitation, the system comprising one or more self-expandable or manually expandable anchors and associated devices for fixating a valve splint within the heart. For example, a spade-shaped assembly may be configured to be deployed in a right ventricle of the heart and to stabilize a puncturing instrument to puncture the septum. Various puncturing instruments may also be part of the anchoring system, including one or more of a flexible needle having a multiplicity of slits disposed along the length of the needle, a trocar catheter with a retractable head, and a catheter needle having a blunt introducer to protect nearby tissue within the heart during advancing a guidewire. A cutter catheter and puncture location catheter may also be part of the system and be used during treatment.
