Abstract

Apparatuses and methods for controlling a medical device delivery assembly are provided. The apparatus can comprise a first engagement device and a coupling mechanism. The first engagement device can be used to engage a first component. The coupling mechanism can have a port and at least one wing. The at least one wing can be disposed adjacent to the port and be configured to facilitate interconnection of the first engagement device with the coupling mechanism.

Claims

1. A control mechanism for a stent delivery assembly, comprising:

an alignment base comprising a first port, a second port proximal to the first port, and a channel extending along a longitudinal axis between the first and second ports, the base further comprising a pair of wings, on opposing sides of the channel, extending outwardly from the base, the wings being movable between a first position in which the channel is in a relaxed, closed configuration and a second position in which the channel is in a deflected, open configuration;

a first engagement device, couplable to the first port, for engaging a first component, wherein when coupled to the first port, the first engagement device is (i) permitted to rotate about the longitudinal axis without causing the first engagement device to move along the longitudinal axis and (ii) restricted from moving along the longitudinal axis relative to the first port; and

a second engagement device, couplable to the second port, for engaging a second component, wherein when coupled to the second port, the second engagement device is (i) permitted to rotate about the longitudinal axis without causing the second engagement device to move along the longitudinal axis and (ii) restricted from moving along the longitudinal axis relative to the second port,

wherein the first and second engagement devices are (i) removable from the first and second ports when the wings are moved to the second position and (ii) retained in the first and second ports when the wings are in the first position to allow the first and second components to be axially aligned along the longitudinal axis.

2. The control mechanism of claim 1, wherein the wings are separated by a slot, extending into and along the channel, configured to permit the second component to be inserted or removed from the channel.

3. The control mechanism of claim 1, wherein the wings both extend in a first plane.

4. The control mechanism of claim 1, wherein the first port is disposed at a first end of the base, and the second port is disposed at a second end of the base, and each of the wings extends from the first end to the second end along opposing sides of the channel.

5. The control mechanism of claim 1, wherein the first port comprises at least one alignment portion, and the first engagement device comprises at least one mating portion configured to be aligned with the alignment portion when the first engagement device is coupled to the first port.

6. The control mechanism of claim 5, wherein the first port comprises a plurality of alignment portions configured to allow the first engagement device to be positioned at a plurality of axial positions relative to the base to adjust a spacing between the first and second engagement devices.

7. The control mechanism of claim 5, wherein the at least one alignment portion comprises a recess, and the at least one mating portion comprises a protrusion.

8. The control mechanism of claim 7, wherein the at least one alignment portion comprises an annular recess, and the at least one mating portion comprises an annular protrusion.

9. The control mechanism of claim 1, wherein the wings move between the first and second positions in a direction transverse to the longitudinal axis.
