摘要：
A delivery catheter is in various embodiments configured to deliver an anchoring device to a native valve annulus of a patient's heart, where the anchoring device can better secure a prosthesis at the native annulus. The delivery catheter can includes a distal section that includes one or more spines or is laser cut to assume a particular shape for better facilitating delivery of the anchoring device at the implant site and can include a flexible tube, a first pull wire, and a second pull wire. The flexible tube can comprise a bore extending between the first end and the second end sized for passing the anchoring device therethrough. The distal portion can comprise a first flexing section and a second flexing section. Actuation of the first pull wire and the second pull wire can cause the flexible tube to move from a first configuration to a second configuration.
