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.
Claims20
A retainer comprising:
- a base including an outer surface;
- a protrusion extending radially outwardly from the base, the protrusion configured to retain an eyelet of a medical device, wherein the protrusion includes a surface at an obtuse angle relative to the outer surface of the base and configured to enable release of the eyelet from the protrusion via rotation of the base.
A medical device delivery system comprising:
- a catheter shaft having a lumen, the catheter including a shaft protrusion extending inwardly from an inner surface of the shaft;
- and
- a retainer disposed within the lumen, the retainer configured to restrain a medical device, wherein the retainer comprises a base and a retainer protrusion extending outwardly from the base,
- wherein the catheter shaft and the retainer are configured such that rotational movement between the catheter shaft and the retainer is configured to cause the shaft protrusion and the retainer protrusion to engage to bump the medical device off the retainer.
1 more element
A method comprising:
- rotating a catheter shaft and/or a retainer to knock a medical device coupled to the retainer off the retainer.
