Abstract

According to an aspect, a medical device includes a needle member having a curved portion, a handle coupled to the needle member, and a pusher member including a sheath and an extension member. The sheath may be bendable. The extension member is configured to be slidably coupled to a track of the handle such that extension member slides within the track during a medical procedure. The sheath defines a lumen configured to receive a portion of the needle member. The extension member is configured to be de-coupled from the track of the handle after the medical procedure. The sheath is configured to be de-coupled from the needle member after the medical procedure. In some examples, the sheath of the pusher member is configured to bend to conform to the curved portion when the sheath of the pusher member is moved over the curved portion of the needle member.

First claim

What is claimed is:

1 . A medical device comprising:
a needle member having a curved portion; a handle coupled to the needle member; and a pusher member including a bendable sheath and an extension member, the extension member configured to be slidably coupled to a track of the handle such that extension member slides within the track during a medical procedure, the bendable sheath defining a lumen configured to receive a portion of the needle member, the extension member configured to be de-coupled from the track of the handle after the medical procedure, the bendable sheath configured to be de-coupled from the needle member after the medical procedure, the bendable sheath of the pusher member configured to conform to the curved portion when the bendable sheath of the pusher member is moved over the curved portion of the needle member.

2 . The medical device of claim 1 , further comprising:
a protrusion component configured to be coupled to the handle, the protrusion component configured to limit movement of the pusher member in relation to the handle during the medical procedure.

3 . The medical device of claim 2 , wherein the protrusion component includes an insert having a base and a flexible projection that extends from the base, the insert configured to be inserted into a slot of the handle such that, when inserted, the flexible projection protrudes into the track of the handle.

4 . The medical device of claim 2 , wherein the protrusion component includes an insert having a flexible projection, the insert being coupled to the track of the handle.

5 . The medical device of claim 2 , wherein the protrusion component includes a removable pin, the handle defining a through-hole configured to receive the removable pin such that a portion of the removable pin protrudes into the track of the handle.

6 . The medical device of claim 2 , wherein the protrusion component includes an adjustable pin assembly including a modified pin and a spring-loaded detent.

7 . The medical device of claim 1 , wherein the extension member defines a slot.

8 . The medical device of claim 1 , wherein the bendable shaft includes a plurality of recesses.

9 . The medical device of claim 1 , wherein the extension member defines an enlarged portion of a proximal end of the extension member.

10 . A medical device comprising:
a needle member; a handle coupled to the needle member; a pusher member including a sheath and an extension member, the extension member configured to be slidably coupled to a track of the handle such that extension member slides within the track during a medical procedure, the sheath defining a lumen configured to receive a portion of the needle member, the pusher member configured to be de-coupled from the handle; and a protrusion component configured to be coupled to the track of the handle, the protrusion component configured to protrude into the track of the handle such that a travel distance of the pusher member is limited.

11 . The medical device of claim 10 , wherein the needle member includes a curved portion, and sheath is bendable such that the sheath is configured to bend over the curved portion of the needle member when decoupling the pusher member from the needle member.

12 . The medical device of claim 10 , wherein the pusher member defines a slot such that the pusher member is configured to be de-coupled from the needle member via the slot.

13 . The medical device of claim 10 , wherein the protrusion component includes an insert having a base and a flexible projection that extends from the base, the insert configured to be inserted into a slot of the handle such that, when inserted, the flexible projection protrudes into the track of the handle.

14 . The medical device of claim 10 , wherein the protrusion component includes an insert having a flexible projection, the insert being coupled to the track of the handle.

15 . The medical device of claim 10 , wherein the protrusion component includes a removable pin, the handle defining a through-hole configured to receive the removable pin such that a portion of the removable pin protrudes into the track of the handle.

16 . The medical device of claim 10 , wherein the protrusion component is adjustable between a first semi-locked position and a second semi-locked position.

17 . The medical device of claim 10 , wherein the extension member defines a slot.

18 . A medical device comprising:
a needle member; a handle coupled to the needle member; a pusher member including a sheath and an extension member, the extension member configured to be slidably coupled to a track of the handle such that extension member slides within the track during a medical procedure, the sheath defining a lumen configured to receive a portion of the needle member, the pusher member configured to be de-coupled from the handle, the pusher member configured to be de-coupled from the handle; and a protrusion component configured to be coupled to the track of the handle, the protrusion including an insert configured to be inserted into a slot of the handle such that, when inserted, the insert is configured to protrude into the track of the handle to limit a travel distance of the pusher member.

19 . The medical device of claim 18 , wherein the insert is removable after the medical procedure.

20 . The medical device of claim 18 , wherein the insert is not removable after the medical procedure.
