Abstract
In some embodiments, a medical device delivery system includes a catheter and a retainer. The retainer can be engaged with the medical device to restrain relative movement of the medical device in one or more axial and/or radial directions. A variety of retainers and retainer systems are disclosed, many of which can reliably disengage the medical device from the retainer. Methods for using the medical device delivery system are also described.
Claims14
A medical device delivery system comprising:
- a catheter sheath having a lumen;
- and
- a retainer disposed within the lumen, the retainer configured to restrain a medical device, wherein the retainer comprises a toggle,
- wherein the catheter sheath and the retainer are configured such that relative axial movement between the catheter sheath and the retainer actuates the toggle such that the toggle bumps the medical device from the retainer.

A medical device delivery system comprising:
- a catheter sheath having a lumen;
- and
- a retainer disposed within the lumen, the retainer configured to restrain a medical device, the retainer including an actuator having a first end, a second end, and a hinge disposed between the first end and the second end and coupling the actuator to a base of the retainer,
- wherein the catheter sheath and the retainer are configured such that relative axial movement between the catheter sheath and the retainer activates the actuator to move the first end radially inward and the second end radially outward to disengage the medical device from the retainer.
