Abstract

A delivery device for a collapsible medical device may include a handle and a delivery assembly having a compartment for receiving the medical device. A catheter member may extend from the handle to the delivery assembly. The catheter member may have a first portion with a first compliance value and a second portion with a second compliance value different from the first compliance value. An internally threaded member may be fixedly connected to the delivery assembly. An externally threaded member may have a first portion operatively connected to the actuation member and a second portion threadedly coupled to the internally threaded member so that manipulation of the actuation member causes axial movement of the compartment relative to the catheter member.

Claims20

Dependent claims

A method of delivering a medical device into a heart valve annulus of a patient, comprising:

positioning the medical device within a distal portion of a catheter member of a delivery device;
positioning a sheath over a proximal portion of the catheter member so that an intermediate portion of the catheter member is uncovered by the sheath, the intermediate portion of the catheter member being positioned between the proximal and distal portions of the catheter member;
advancing the catheter member to a position adjacent the heart valve annulus within the patient while the intermediate portion of the catheter member is uncovered by the sheath and the distal portion of the catheter member has a first relative orientation with respect to the proximal portion of the catheter member;
advancing the sheath distally to at least partially cover the intermediate portion of the catheter member while the catheter member is adjacent the heart valve annulus to change the first relative orientation to a different second relative orientation;
and
delivering the medical device into the heart valve annulus of the patient while the distal portion of the catheter member is in the second relative orientation.
