Abstract: An implantable prosthetic valve that is radially collapsible to a collapsed configuration and radially expandable to an expanded configuration comprises an annular frame having an inflow end and an outflow end, a leaflet structure positioned within the frame and secured thereto, and a laminate sealing member comprising an encapsulating material. The laminate sealing member has a main portion that encapsulates at least a portion of the frame and an end portion extending from the inflow end of the frame, and the end portion of the laminate sealing member is folded to form a cuff adjacent the inflow end of the frame and secured to the main portion of the laminate sealing member.

Abstract: Docking stations for transcatheter valves are described. The docking stations can include an expandable frame, at least one sealing portion, and a valve seat. The expandable frame can be configured to conform to an interior shape of a portion of the circulatory system when expanded inside the circulatory system. The sealing portion can be configured to contact an interior surface of the circulatory system to create a seal. The valve seat can be connected to the expandable frame and can be configured to support an expandable transcatheter valve. The docking stations are adaptable to different anatomies/locations to allow implantation of a transcatheter valve in a variety of anatomies/locations.

Abstract: The expandable sheath and methods of use disclosed herein are used to deliver a prosthetic device through a patient's vasculature. The sheath is constructed to be expandable in the circumferential direction, while maintaining sufficient stiffness in the longitudinal direction to withstand pushing and resist kinking The sheath includes a plurality of curved arms extending outwardly from a longitudinally extending spine. The curved arms move away from the longitudinal axis of the sheath when pushed radially outwardly by a passing prosthetic device, and move back toward the longitudinal axis once the prosthetic device has passed.

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: 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.
