Abstract

The disclosed technology includes an apparatus to a grip a catheter shaft including a body including a proximal end extending along a central axis to a distal end. The body can include a first handle portion, a second handle portion, and a catheter shaft grip aperture. The first handle portion can define a first recess extending along the central axis of the body from the proximal end to the distal end. The second handle portion can define a second recess extending along the central axis of the body from the proximal end to the distal end such that the first recess is aligned with the second recess. The catheter shaft grip aperture can extend along the central axis of the body from the proximal end to the distal end, be formed from the alignment of the first recess and the second recess, and be sized to receive a catheter shaft.

First claim

What is claimed is:

1 . An apparatus to grip a catheter shaft, the apparatus comprising:
a body including a proximal end and extending along a central axis to a distal end, and comprising:
a first handle portion defining a first recess extending along the central axis of the body from the proximal end to the distal end;
a second handle portion defining a second recess extending along the central axis of the body from the proximal end to the distal end such that the first recess is aligned with the second recess, and
a catheter shaft grip aperture extending along the central axis of the body from the proximal end to the distal end, formed from the alignment of the first recess and the second recess, the catheter shaft grip aperture being sized to receive a catheter shaft.

2 . The apparatus of claim 1 , wherein the catheter shaft grip aperture frictionally engages a catheter shaft and transfers rotational force applied to the body to a catheter shaft.

3 . The apparatus of claim 1 , the catheter shaft grip aperture comprising:
a relaxed state where the catheter shaft grip aperture receives a catheter shaft and is freely movable along a catheter shaft; and a grip state, where a force applied to the body causes the catheter shaft grip aperture to frictionally engage a catheter shaft.

4 . The apparatus of claim 1 , the first handle portion comprising a first connector extending outwardly from the first handle portion, and
the second handle portion comprising a second connector configured to receive the first connector and attach the first handle portion and the second handle portion to each other.

5 . The apparatus of claim 4 , wherein the first connector comprises a first male connector disposed proximate the proximal end and the second connector comprises a first female connector disposed proximate the proximal end,
wherein the first handle portion further comprises a second male connector extending outwardly from the first handle portion and disposed proximate the distal end, and wherein the second handle portion further comprises a second female connector disposed proximate the distal end and configured to receive the second male connector to attach the first handle portion and the second handle portion to each other.

6 . The apparatus of claim 1 , the first handle portion including a first hinge portion and the second handle portion including a second hinge portion, the first hinge portion and the second hinge portion rotatably connected to each other such that the first handle portion and the second handle portion can be rotated between an engaged configuration and a disengaged configuration.

7 . The apparatus of claim 6 , the first handle portion further comprising a male connector disposed on a side of the first handle portion opposite the first hinge portion,
the second handle portion further comprising a female connector disposed on a side of the second handle portion opposite the second hinge portion such that the female connector is configured to receive the male connector and secure the first handle portion to the second handle portion when in the engaged configuration.

8 . The apparatus of claim 1 , the first handle portion further comprising a second recess extending into the first handle portion generally perpendicularly to the central axis; and
the second handle portion further comprising a protrusion extending outwardly from second handle portion generally perpendicularly to the central axis, wherein the second recess is configured to receive the protrusion to facilitate alignment of the first handle portion with the second handle portion.

9 . The apparatus of claim 1 further comprising a retention member configured to apply a force to a catheter shaft when the retention member is in an engaged position.

10 . The apparatus of claim 9 , wherein the retention member is rotatable between the engaged position and a disengaged position.

11 . The apparatus of claim 10 , wherein the retention member comprises a lever arm including an engagement end configured to engage a catheter shaft, and
wherein the lever arm is configured to be actuated between the engaged position and the disengaged position by a user pushing on the lever arm at an end opposite the engagement end.

12 . The apparatus of claim 10 , wherein the retention member is biased to remain in the engaged position.

13 . The apparatus of claim 12 , wherein the retention member is spring-loaded.

14 . The apparatus of claim 1 , wherein the body further comprises a proximal attachment end configured to attach to a handle device of a catheter assembly.

15 . The apparatus of claim 1 , wherein the body further comprises a distal attachment end configured to attach to a valve of a catheter assembly.

16 . The apparatus of claim 1 , wherein the body further comprises a tip proximate the distal end configured to serve as an insertion tool.

17 . A handle for gripping a catheter shaft, the handle comprising:
a first handle portion defining a first channel extending from a proximal end to a distal end of the first handle portion; and a second handle portion defining a second channel extending from a proximal end to a distal end of the second handle portion, the first handle portion and the second handle portion attachable to each other to form a handle including an aperture extending therethrough formed by the first channel and the second channel, the aperture sized to receive a catheter shaft.

18 . The handle of claim 17 , the first handle portion comprising a first connector extending outwardly from the first handle portion, and
the second handle portion comprising a second connector configured to receive the first connector and attach the first handle portion and the second handle portion to each other.

19 . The handle of claim 18 , wherein the first connector comprises a first male connector disposed proximate the proximal end of the first handle portion and the second connector comprises a first female connector disposed proximate the proximal end of the second handle portion,
wherein the first handle portion further comprises a second male connector extending outwardly from the first handle portion and disposed proximate the distal end of the first handle portion, and wherein the second handle portion further comprises a second female connector disposed proximate the distal end of the second handle portion and configured to receive the second male connector to attach the first handle portion and the second handle portion to each other.

20 . A method of manipulating a catheter shaft using an attachable handle, the method comprising:
aligning a first handle portion with a catheter shaft; inserting a catheter shaft into a first recess of the first handle portion, the first recess extending along a central axis of the first handle portion; aligning a second handle portion with the first handle portion; attaching the second handle portion to the first handle portion to form a handle, the second handle portion including a second recess extending along a central axis of the second handle portion such that the first recess and the second recess form an aperture through the handle, the aperture being sized to receive a catheter shaft; and gripping the handle and manipulating a catheter shaft by rotating the handle.
