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.

First claim

What is claimed is:

1. A medical device cleaning tool, comprising:
a housing comprising a first portion and a second portion, wherein the housing includes a decreasing diameter taper from the first portion of the housing to the second portion of the housing;
a chamber formed within the second portion of the housing, the chamber defining an opening at a distal end of the housing; and
an elongate member disposed within the housing, wherein a first portion of the elongate member is secured within the first portion of the housing and a second portion of the elongate member extends into the chamber.

2. 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.

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

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

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

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

7. 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.

8. The medical device cleaning tool of claim 7 , wherein the second portion of the elongate member includes an outer dimension configured to extend into a fluid delivery lumen of the medical device.

9. The medical device cleaning tool of claim 8 , wherein the fluid delivery lumen includes an injection lumen and a main lumen, and wherein the second portion of the elongate member includes a length sufficient to extend through the injection lumen and into the main lumen.

10. The medical device cleaning tool of claim 9 , wherein the injection lumen includes an inner dimension less than an inner dimension of the main lumen and greater than an outer dimension of the second portion of the elongate member.

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

12. The medical device cleaning tool of claim 1 , further comprising a clip attachment disposed on an outer surface of the first portion of the housing.

13. A medical device cleaning tool, comprising:
a housing including a first portion and a second portion, wherein the housing includes a decreasing diameter taper from the first portion of the housing to the second portion of the housing;
a chamber formed within the second portion of the housing, the chamber defining an opening at a distal end of the housing;
an elongate member disposed within the housing, wherein a first portion of the elongate member is secured within the first portion of the housing and a second portion of the elongate member extends into the chamber;
a plate disposed within the chamber, the plate defining an opening configured to receive the second portion of the elongate member; and
a spring disposed within the chamber and around the elongate member proximal to the plate.

14. The medical device cleaning tool of claim 13 , wherein the opening of the chamber includes an inner dimension less than an inner dimension of the remaining portion of the chamber, and
wherein at least the second portion of the housing is rigid.

15. The medical device cleaning tool of claim 14 , wherein the inner dimension of the opening defines a first planar surface configured to contact a distal end of the plate and a proximal end of the chamber defines a second planar surface configured to contact a proximal end of the spring.

16. The medical device cleaning tool of claim 15 , wherein the plate is configured to move from a first axial position in which the plate is in contact with the first planar surface and the spring is substantially uncompressed between the first and second planar surfaces and a second axial position in which the plate moves toward the second planar surface and the spring is compressed between the first and second planar surfaces.

17. The medical device cleaning tool of claim 16 , wherein the plate is configured to move from the first to second axial position when a distal portion of a medical device is advanced into the chamber, and wherein the plate is configured to move from the second to first axial position when a distal portion of a medical device is removed from within the chamber.

18. A medical device cleaning tool, comprising:
a housing comprising 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; and
an elongate member disposed within the housing, wherein a first portion of the elongate member is secured within the first portion of the housing and a second portion of the elongate member extends into the chamber,
wherein the housing includes a decreasing diameter taper from the first portion of the housing to the second portion of the housing.

19. The medical device cleaning tool of claim 18 , wherein the elongate member extends a length through a portion of the chamber, and
wherein the length through the portion of the chamber is less than a total length of the chamber.
