## Abstract

The present disclosure relates generally to the field of medical devices and medical device accessories. In particular, the present disclosure relates to a tool or accessory for cleaning a medical device. For example, the tool or accessory may clean a fluid delivery lumen of an endoscopic submucosal dissection (ESD) knife. The tool or accessory may include a housing with a first portion of an elongate member secured within a first portion of the housing and a second portion of the elongate member extending into a chamber of the housing.

## Claims

### Claim 1

A medical device cleaning tool, comprising:
a housing comprising a first portion and a second portion, wherein at least a portion of the second portion of the housing is rigid;
a chamber formed within the second portion of the housing, the chamber defining an opening at a distal end of the housing, wherein the chamber includes a fixed longitudinal length; and
a member fixed within the housing, wherein a first portion of the member is secured within the first portion of the housing, wherein a second portion of the member extends into the chamber, and wherein a distal end of the member and the opening are both respectively fixed lengths from the first portion of the housing.

### Claim 2 (depends on 1)

The medical device cleaning tool of claim 1, wherein an inner dimension of the chamber is substantially constant along a full length of the chamber.

### Claim 3 (depends on 1)

The medical device cleaning tool of claim 1, wherein the second portion of the member is substantially centered within the chamber.

### Claim 4 (depends on 1)

The medical device cleaning tool of claim 1, wherein the second portion of the member includes a substantially cylindrical outer dimension.

### Claim 5 (depends on 1)

The medical device cleaning tool of claim 1, wherein the second portion of the member includes a helical groove.

### Claim 6 (depends on 1)

The medical device cleaning tool of claim 1, wherein the second portion of the member includes a helical twist.

### Claim 7 (depends on 1)

The medical device cleaning tool of claim 1, wherein the first portion of the member includes an anchoring element configured to secure the first portion of the member within the housing.

### Claim 8 (depends on 1)

The medical device cleaning tool of claim 1, wherein the opening and chamber of the housing include an inner dimension configured to receive a corresponding outer dimension of a medical device.

### Claim 9 (depends on 8)

The medical device cleaning tool of claim 8, wherein the second portion of the member includes an outer dimension configured to extend into a fluid delivery lumen of the medical device.

### Claim 10 (depends on 9)

The medical device cleaning tool of claim 9, wherein the fluid delivery lumen includes an injection lumen and a main lumen, and wherein the second portion of the member includes a length sufficient to extend through the injection lumen and into the main lumen.

### Claim 11 (depends on 1)

The medical device cleaning tool of claim 1, wherein the member is a shaft, a rod, a pin, or a post.

### Claim 12 (depends on 1)

The medical device cleaning tool of claim 1, further comprising:
a plate disposed within the chamber, the plate defining an opening configured to receive the second portion of the member; and
a spring disposed within the chamber and around the member proximal to the plate.

### Claim 13

A medical device cleaning tool, comprising:
a housing including a first portion and a second portion, wherein at least the second portion of the housing is rigid;
a chamber formed within the second portion of the housing, the chamber defining an opening at a distal end of the housing, wherein the opening is spaced away from the first portion of the housing by a fixed distance; and
a member disposed within the housing, wherein a first portion of the member is secured within the first portion of the housing, and wherein a second portion of the member extends into at least a portion of the chamber, and wherein the first portion of the member includes an anchoring element including an enlarged end section that is configured to secure the first portion of the member within the housing such that the member is fixedly positioned relative to the first portion and to the second portion of the housing.

### Claim 14 (depends on 13)

The medical device cleaning tool of claim 13, wherein the opening and chamber of the housing include an inner dimension configured to receive a corresponding outer dimension of a medical device.

### Claim 15 (depends on 14)

The medical device cleaning tool of claim 14, wherein the second portion of the member includes an outer dimension configured to extend into a fluid delivery lumen of the medical device.

### Claim 16 (depends on 13)

The medical device cleaning tool of claim 13, wherein the member is a shaft, a rod, a pin, or a post.

### Claim 17 (depends on 13)

The medical device cleaning tool of claim 13, wherein the member includes a helical groove or a helical twist.

### Claim 18

A method of using a medical device cleaning tool, comprising:
using a medical device to treat a treatment site, wherein the medical device includes a fluid delivery lumen in at least a distal portion of the medical device, and wherein using the medical device to treat the treatment site includes delivering fluid to the treatment site through the fluid delivery lumen;
removing the medical device from the treatment site; and
inserting the distal portion of the medical device into a portion of the medical device cleaning tool to break-up and/or remove debris from the fluid delivery lumen,
wherein the medical device cleaning tool includes:
a housing comprising a first portion and a second portion, wherein at least a portion of the second portion of the housing is rigid;
a chamber formed within the second portion of the housing, the chamber defining an opening at a distal end of the housing, wherein the opening is spaced away from the first portion of the housing by a fixed distance; and
a member disposed within the housing, wherein a first portion of the member is secured within the first portion of the housing, and wherein a second portion of the member extends into the chamber, wherein the first portion of the member includes an anchoring element including an enlarged end section that is configured to secure the first portion of the member within the housing such that the member is fixedly positioned relative to the first portion and to the second portion of the housing, and wherein at least a portion of the second portion of the member is sized to be received within the fluid delivery lumen to break-up and/or remove the debris from the fluid delivery lumen.

### Claim 19 (depends on 18)

The method of claim 18, wherein the fluid delivery lumen includes an injection lumen and a main lumen, and wherein the second portion of the member includes a length sufficient to extend through the injection lumen and into the main lumen.

### Claim 20 (depends on 18)

The method of claim 18, wherein the medical device is a knife, and wherein the method further comprises moving the medical device cleaning tool relative to the knife.
