Abstract

A method for positioning a device, such as an endcap, on an endoscope is disclosed. The method can be used, for example, for facilitating pressing an endcap onto an endoscope, including in those applications where the endscope is disposed in a sheath and the endcap is positioned at the distal end of the sheath.

Claims

1. A method for positioning a device on an endoscope comprising the steps of:

providing an endoscope;

providing a device sized to be positioned on an end of the endoscope; and

applying a pushing force on the device while simultaneously applying a pulling force on the endoscope, wherein the pulling force applied to the endoscope is applied through an opening in the device.

2. The method of claim 1 wherein the pulling force applied to the endoscope is applied through a through bore in the device.

3. The method of claim 1 wherein the pulling force is applied through an opening in the device sized to receive the end of the endoscope.

4. The method of claim 1 wherein the device comprises an endcap having a bore for receiving an end of the endoscope, and wherein the pulling force is applied to the endoscope through the bore in the endcap.

5. The method of claim 1 wherein the device is positioned on an endoscope disposed in a sheath, and wherein the step of applying the pulling force on the endoscope is performed without grasping the sheath.

6. The method of claim 1 wherein the pulling force is applied to the endoscope radially inward of the outer surface of the endoscope.

7. The method of claim 1 wherein the pulling force is applied to a surface of a channel within the endoscope.

8. The method of claim 1 wherein the pulling force is applied around the distal end of the endoscope.

9. The method of claim 1 comprising the step of engaging an inside surface of the endoscope.

10. The method of claim 1 comprising engaging the inside surface of an endoscope by expanding a member within the endoscope.

11. A method of positioning and endcap on an endoscope comprising the steps of:

providing an endoscope;

providing a sheath for receiving the endoscope;

providing an endcap associated with the distal end of the sheath;

positioning the endoscope at least partially within the sheath; and

applying a force to the endoscope through the endcap.

12. The method of claim 11 further comprising the step of applying a force to the endcap.

13. The method of claim 11 further comprising the step of a pushing force to the endcap simultaneously with applying a pulling force on the endoscope.

14. The method of claim 11 wherein the step of applying a force to the endoscope is performed without contacting the sheath.

15. The method of claim 11 comprising applying a pulling force to the endoscope simultaneously with applying a pushing force to the endcap, wherein the pulling force is applied to an outer surface of the endoscope.

16. The method of claim 11 comprising applying a pulling force to the endoscope simultaneously with applying a pushing force to the endcap, wherein the pulling force is applied to a surface associated with an internal channel of the endoscope.

17. A method of positioning and endcap on an endoscope comprising the steps of:

providing an endoscope;

providing a sheath for receiving the endoscope;

providing an endcap disposed at a distal end of the sheath;

positioning the endoscope at least partially within the sheath; and

pressing the endcap onto a distal end of the endoscope without grasping the sheath.

18. A method of positioning an endcap on an endoscope comprising the steps of:

providing an endoscope;

providing a loading element having a first end and a second end, the second end adapted to releasably engage the distal end of the endoscope;

releasably positioning the loading element on the distal end of the endoscope;

inserting the first end of the of the loading element at least partially through the endcap; and

pulling on the loading element while pushing on the endcap.
