Abstract

Support devices and associated systems and methods for releasably retaining a delivery system handle while delivering a medical device to a target within a human are described herein. The support device is configured to engage the delivery system handle and enable a user to maneuver a distal end portion of the delivery system by manipulating features of the support device.

First claim

What is claimed is:

1. A support device for releasably retaining a delivery system handle while delivering a medical device to a target site within a human body, the support device comprising:
a first base carrying a first support configured to engage a first handle component of the delivery system handle;
a second base carrying a second support configured to engage a second handle component of the delivery system handle, wherein at least a portion of the second base is on the first base, wherein the first and second supports extend away from the first and second bases, respectively; and
a first translation assembly operably coupled to the first base and the second base, wherein the first translation assembly is configured to slidably translate the second base with respect to the first base, and wherein the first translation assembly is configured to longitudinally translate the second handle component with respect to and independent of the first handle component when the delivery system handle is supported by the support device.

2. A support device for releasably retaining a delivery system handle while delivering a medical device to a target site within a human body, the support device comprising:
a first base carrying a first support configured to engage a first handle component of the delivery system handle;
a second base carrying a second support configured to engage a second handle component of the delivery system handle, wherein at least a portion of the second base is on the first base, wherein the first and second supports extend away from the first and second bases, respectively;
a first translation assembly operably coupled to the first base and the second base, wherein the first translation assembly is configured to slidably translate the second base with respect to the first base, and wherein the first translation assembly is configured to longitudinally translate the second handle component with respect to and independent of the first handle component when the delivery system handle is supported by the support device;
a third base carrying a third support configured to engage a third handle component of the delivery system handle, wherein at least a portion of the second base is positioned between the first base and the third base, and wherein the third support extends in a direction away from the third base; and
a second translation assembly operably coupled to the second base and the third base, wherein the second translation assembly is configured to slidably translate the third base with respect to the second base to longitudinally translate the third handle component with respect to and independent of the second handle component when the delivery system handle is supported by the support device.

3. A support device for releasably retaining a delivery system handle while delivering a medical device to a target site within a human body, the support device comprising:
a first base carrying a first support configured to engage a first handle component of the delivery system handle;
a second base carrying a second support configured to engage a second handle component of the delivery system handle, wherein at least a portion of the second base is on the first base, wherein the first and second supports extend away from the first and second bases. respectively:
a first translation assembly operably coupled to the first base and the second base, wherein the first translation assembly is configured to slidably translate the second base with respect to the first base, and wherein the first translation assembly is configured to longitudinally translate the second handle component with respect to and independent of the first handle component when the delivery system handle is supported by the support device; and
a spacer component configured to space apart a portion of the first base from a surface on which the support device is configured to rest, wherein the spacer component is configured to orient the first base and the second base at an acute angle with respect to the surface on which the support device is configured to rest.

4. A support device for releasably retaining a delivery system handle while delivering a medical device to a target site within a human body, the support device comprising:
a first base carrying a first support configured to engage a first handle component of the delivery system handle;
a second base carrying a second support configured to engage a second handle component of the delivery system handle, wherein at least a portion of the second base is on the first base, wherein the first and second supports extend away from the first and second bases, respectively; and
a first translation assembly operably coupled to the first base and the second base, wherein the first translation assembly is configured to slidably translate the second base with respect to the first base, and wherein the first translation assembly is configured to longitudinally translate the second handle component with respect to and independent of the first handle component when the delivery system handle is supported by the support device;
wherein the first translation assembly comprises a first rack, a first pinion, and a first knob operably coupled to the first pinion, the first pinion being configured to rotate upon manipulation of the first knob such that the first rack translates longitudinally with respect to the first pinion to move the first and second bases relative to each other.

5. The support device of claim 4 , wherein a surface of the first base or the second base comprises the rack.

6. The support device of claim 5 , wherein the rack comprises a plurality of spaced apart protrusions or a plurality of spaced apart apertures.

7. The support device of claim 1 , wherein the first translation assembly comprises a worm gear.

8. The support device of claim 1 , wherein:
the first support comprises a first fastener configured to releasably secure the first handle component to the first base.

9. The support device of claim 2 , wherein the third support comprises a back-support configured to engage a cross-sectional end portion of the delivery system handle.

10. The support device of claim 3 , further comprising a platform, wherein the first base is coupled to the platform, and wherein the platform comprises a first end portion and a second end portion.

11. The support device of claim 10 , wherein:
the platform defines a platform axis extending through the first and second end portions;
the first base has a first terminus proximate to the first end portion of the platform and a second terminus spaced apart from the first end portion along the platform axis;
the first base has a first axis extending through the first and second termini of the first base; and
the spacer component is configured to space the second terminus of the first base from the platform such that the platform axis and the first axis form the acute angle.

12. The support device of claim 11 , wherein the spacer component is adjustable, and wherein adjusting the spacer component changes the acute angle.

13. The support device of claim 2 , further comprising a spacer component configured to space apart a portion of the first base from a surface on which the support device is configured to rest, wherein the spacer component is configured to orient the first base and the second base at an acute angle with respect to the surface on which the support device is configured to rest.

14. The support device of claim 2 , wherein the first translation assembly comprises a first rack, a first pinion, and a first knob operably coupled to the first pinion, the fir
