摘要： A method include of delivering a heart valve prosthesis includes loading the heart valve prosthesis in a crimped configuration within a dilator shaft, tracking the dilator shaft within a vasculature of a patient to a desired site with the heart valve prosthesis loaded therewithin, advancing a delivery device through the dilator shaft to the distal end of the dilator shaft, advancing the delivery device through the heart valve prosthesis to load the heart valve prosthesis onto the delivery device, advancing the delivery device with the heart valve prosthesis mounted thereon past the distal end of the dilator shaft to a treatment site within the vasculature of the patient, and deploying the heart valve prosthesis from the delivery device at the treatment site.

摘要： Methods of transcatheter delivery of a prosthetic heart valve. A distal region of a guide member assembly is advanced into a heart of a patient. The distal region is docked to native anatomy of the heart. A delivery device, including a collapsed prosthetic heart valve, is advanced over the docked guide member assembly. The collapsed prosthetic heart valve is located at an implantation site. The prosthetic heart valve is deployed from the delivery device, and then the delivery device is removed from the patient. At least a portion of the guide member assembly is removed from the patient. In some embodiments, the docking structure is docked to one or more of native mitral valve leaflets, chordae in the left ventricle, or walls of the left ventricle as part of a transseptal mitral valve delivery procedure.

摘要： Aspects of the present disclosure provide a delivery device including a tubular outer jacket having a distal end and a tyne assembly including a shaft supporting at least one tyne. In some aspects, an inner jacket is positioned within the outer jacket, wherein the tyne assembly is positioned between the outer jacket and the inner jacket. The delivery device has a delivery configuration in which the tynes are maintained within the outer jacket and a deployed configuration in which the tynes extend from a distal end of the tubular outer jacket. Aspects of the disclosure also provide methods of conducting a percutaneous coronary intervention including utilizing one or more tyne assemblies to engage the tynes of each tyne assembly with the frame to maintain the position of the delivery device.
