Abstract

According to one aspect, a medical device may be configured for use with an endoscope and may include a tool. The tool may include an actuator, at least one extension at a distal portion of the actuator, and a distal end. The at least one extension may extend radially outward from the actuator and may have an edge configured to fragment debris within a body. The medical device may also include a cap configured for coupling to a distal end of the endoscope, and the cap may include a body defining an opening and a cavity. The opening may be configured to align with optics of the endoscope, and the at least one extension may be positioned within the cavity of the body.

First claim

We claim:

1. A medical device configured for use with an endoscope, comprising:
a tool having an actuator and at least one extension at a distal portion of the actuator, and a distal end, wherein the at least one extension extends radially outward from the actuator and has an edge configured to fragment debris within a body; and
a cap configured for coupling to a distal end of the endoscope, the cap including a body defining an opening and a channel;
wherein the opening is configured to align with optics of the endoscope, and the at least one extension is positioned within the channel of the body;
wherein a distal tip of the tool is secured within a cavity of the cap to restrict longitudinal movement of the tool and allow rotational movement of the tool about a longitudinal axis of the tool.

2. The device of claim 1 , further comprising a catheter defining a lumen housing the actuator of the tool, the lumen in fluid communication with the channel of the body of the cap.

3. The device of claim 2 , wherein the cap is integral with the catheter.

4. The device of claim 2 , further comprising an adapter, wherein the adapter includes a device port, a vacuum port, and a catheter port; wherein the device port is configured to receive the tool; and wherein the catheter port is coupled to the catheter.

5. The device of claim 1 , wherein the opening of the cap extends from a proximal end of the cap to a distal end of the cap.

6. The device of claim 1 , wherein the at least one extension is helically-shaped, tear-drop shaped, or arch-shaped.

7. The device of claim 1 , wherein the at least one extension is a plurality of wires radially spaced around the actuator.

8. The device of claim 1 , wherein the channel is configured to couple to a fluid channel of the endoscope.

9. The device of claim 1 , wherein the at least one extension of the tool is configured to rotate within the channel.

10. The device of claim 1 , wherein the cavity of the cap has a length permitting a range of longitudinal movement of the tool.

11. The device of claim 1 , wherein the cap is cylindrical, and the channel extends from a radially outer portion of the cap to a radially inner portion of the cap.

12. The device of claim 1 , wherein the channel opens to a side of the cap and the opening opens to an end of the cap transverse to the side of the cap.

13. The device of claim 1 , wherein the distal tip of the tool includes a spherical tip.

14. The device of claim 13 , wherein the spherical tip is positioned within the cavity.

15. The device of claim 1 , where the distal tip of the tool is coupled to a portion of the cap via a magnetic material.
