Abstract

A device retention assembly includes a delivery system and a device retention mechanism retaining the delivery system. The device retention mechanism includes a tray, a base coupled to the tray, and retaining flanges pivotally coupled to the base. The delivery system is enclosed within an opening defined by the base and retaining flanges. A key locks the device retention mechanism in the closed position retaining the delivery system. The key must be removed to unlock the device retention mechanism to release the delivery system.

Claims

1. A device retention mechanism comprising:

a base;

a tray, the base being coupled to the tray;

retaining flanges;

pivots coupling the retaining flanges to the base;

locking plates coupled to the retaining flanges such that the retaining flanges and the locking plates are pivotally coupled to the base by the pivots; and

locking plate apertures configured to receive the locking plates, wherein the tray comprises the locking plate apertures, wherein the locking plates are spaced apart from the locking plate apertures when the retaining flanges are in a closed position,

wherein the base comprises a device retaining surface configured to receive a delivery system,

wherein the retaining flanges comprise device retaining surfaces configured to receive the delivery system,

wherein the device retaining surface of the base and the device retaining surfaces of the retaining flanges collectively define a cylindrical surface.

2. The device retention mechanism of claim 1 wherein the retaining flanges are adjacent one another with a gap in between when in the closed position.

3. The device retention mechanism of claim 1 wherein the locking plates lie in a common plane.

4. A device retention mechanism comprising:

a base;

retaining flanges;

pivots coupling the retaining flanges to the base;

locking plates coupled to the retaining flanges;

locking plate apertures configured to receive the locking plates; and

a device removal assist card configured to prevent the locking plates from entering into the locking plate apertures.

5. The device retention mechanism of claim 4 wherein the device removal assist card is located between the locking plates and the locking plate apertures.

6. The device retention mechanism of claim 5 wherein the device removal assist card is removable to allow the locking plates to access the locking plate apertures.

7. The device retention mechanism of claim 4 further comprising:

proximal locking plate retaining posts;

distal locking plate retaining posts, wherein the locking plate apertures are between the proximal locking plate retaining posts and the distal locking plate retaining posts.
