Claim 9:
10. A method comprising:
engaging a clamping assembly of a handle of a medical device delivery catheter for a first time to restrain movement of an inner tool through an elongated member lumen of an elongated member disposed within the handle, wherein engaging the clamping assembly comprises actuating a button of the clamping assembly toward a longitudinal axis of the elongate member in a direction transverse to the longitudinal axis to compress the elongated member against the inner tool, wherein the clamping assembly comprises a semi-cylindrical member configured to support an underside of the elongated member, wherein engaging the clamping assembly comprises actuating the button from a first position to a second position in which the button compresses the elongated member against the inner tool, and wherein the button is further configured to be actuated from the second position to the first position in response to a longitudinal force in a direction of the distal end of the catheter;
with the clamping assembly engaged for the first time, introducing a distal end of a shaft of the delivery catheter into a vasculature of a patient toward a tissue site, wherein the shaft comprises a shaft lumen extending from a proximal end of the shaft to a distal end of the shaft, wherein the handle is connected to the proximal end of the shaft, wherein the shaft lumen is in fluid communication with the elongated member lumen, wherein the shaft lumen and the elongated member lumen are configured to receive the inner tool, and wherein the inner tool is configured to interface with an implantable medical device;
releasing the clamping assembly, wherein releasing the clamping assembly comprises actuating the button of the clamping assembly away from the longitudinal axis of the elongate member;
with the clamping assembly released, actuating the inner tool, wherein actuating the inner tool comprises moving the inner tool through the shaft lumen and the elongated member lumen;
after actuating the inner tool, engaging the clamping assembly a second time to restrain movement of the inner tool through the elongated member lumen; and
with the clamping assembly engaged the second time, proximally withdrawing the shaft from the patient.
