1. An implantable medical device delivery catheter comprising:
a shaft configured to extend through a vasculature of a patient, wherein the shaft comprises a shaft lumen extending from a proximal end of the shaft to a distal end of the shaft; and
a handle connected to the proximal end of the shaft, the handle comprising:
an elongated member disposed within the handle, the elongated member comprising an elongated member lumen in fluid communication with the shaft lumen, wherein the elongated member lumen and the shaft lumen are configured to receive an inner tool configured to extend through the elongated member lumen and the shaft lumen and interface with an implantable medical device; and
a clamping assembly comprising a button configured to be actuated toward a longitudinal axis of the elongated member in a direction transverse to the longitudinal axis to compress the elongated member against the inner tool to restrain movement of the inner tool through the elongated member lumen, wherein the clamping assembly comprises a semi-cylindrical member configured to support an underside of the elongated member, wherein the button is configured to be actuated 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.
