Transseptal delivery systems having a deflecting segment and methods of use

A delivery system for delivering a heart valve prosthesis includes a delivery catheter and a heart valve prosthesis. The delivery catheter includes an outer sheath, an inner shaft, a distal nosecone, and a deflecting segment. The inner shaft is slidably disposed within the outer sheath. A distal end...

Beschreibung
Zusammenfassung:	A delivery system for delivering a heart valve prosthesis includes a delivery catheter and a heart valve prosthesis. The delivery catheter includes an outer sheath, an inner shaft, a distal nosecone, and a deflecting segment. The inner shaft is slidably disposed within the outer sheath. A distal end of the inner shaft is coupled to a proximal end of the deflecting segment, and a distal end of the deflecting segment is coupled to the distal nosecone. The deflecting segment includes a delivery state with the deflecting segment and the distal nosecone having a combined first longitudinal length. The deflecting segment further includes a deflected state with the deflecting segment having a second longitudinal length that is less than the first longitudinal length. The heart valve prosthesis includes a radially collapsed configuration and a radially expanded configuration. The deflecting segment is shape-set to the deflected state.
