Abstract

A sheath adapter may be used within a medical device to provide one or more additional lumens. One sheath for use with a medical device may comprise a C-shaped elongate shaft extending from a proximal end to a distal end, the C-shaped elongate shaft configured to fit onto a shaft of the medical device and a lumen extending at least partially along a length of the elongate shaft, the lumen having a first port disposed proximate the distal end of the C-shaped elongate shaft and a second port disposed proximate the proximal end of the C-shaped elongate shaft.

Claims

1. A sheath for use with a medical device, the sheath comprising:

a C-shaped elongate shaft extending from a proximal end to a distal end, the C-shaped elongate shaft configured to fit onto a shaft of the medical device; and

a lumen extending at least partially along a length of the elongate shaft, the lumen having a first port disposed proximate the distal end of the C-shaped elongate shaft and a second port disposed proximate the proximal end of the C-shaped elongate shaft.

2. The sheath of claim 1, wherein the lumen is a first lumen, and the sheath further comprising a second lumen having a first port disposed proximate the distal end of the C-shaped elongate shaft and a second port disposed proximate the proximal end of the C-shaped elongate shaft.

3. The sheath of claim 2, wherein the second port of the second lumen is the second port of the first lumen.

4. The sheath of claim 1, wherein the first port of the lumen is disposed on a distal-facing surface of the C-shaped elongate shaft.

5. The sheath of claim 1, wherein the first port of the lumen is disposed on a side of the C-shaped elongate shaft.

6. The sheath of claim 1, further comprising a connecting member disposed at the second port of the lumen, wherein the connecting member is configured to connect to a pressure sensor.

7. The sheath of claim 1, further comprising a connecting member disposed at the second port of the lumen, wherein the connecting member is configured to connect to a fluid line.

8. The sheath of claim 1, further comprising a connecting member disposed at the second port of the lumen, wherein the connecting member is configured to connect to an aspiration line.

9. The sheath of claim 1, wherein the C-shaped elongate shaft is configured to securely snap onto the shaft of the medical device.

10. The sheath of claim 1, wherein the C-shaped elongate shaft has a circularly shaped cross-section with a gap having a gap width, the cross-section defining a channel having a channel diameter, and wherein the gap width is less than the channel diameter.

11. The sheath of claim 1, wherein the C-shaped elongate shaft is configured to flex in order to fit onto the shaft of the medical device.

12. The sheath of claim 1, wherein the medical device comprises an endoscope.

13. A medical device sheath comprising:

an elongate shaft extending from a proximal end to a distal end, the elongate shaft having a channel extending from the proximal end to the distal end, wherein a wall of the elongate shaft only partially surrounds the channel, the channel configured to receive a shaft of a medical device therein; and

a lumen extending at least partially along a length of the elongate shaft within the wall of the elongate shaft, the lumen having a proximal port disposed proximate the proximal end of the elongate shaft and a distal port disposed proximate the distal end of the elongate shaft.

14. The medical device sheath of claim 13, further comprising a connection member disposed at the proximal end of the elongate shaft, the connection member configured to connect to the medical device.

15. The medical device sheath of claim 13, wherein the medical device is an endoscope or a hysteroscope.

16. The medical device sheath of claim 13, wherein the channel has a channel diameter, and wherein the channel diameter is less than or equal to a diameter of the shaft of the medical device.

17. The medical device sheath of claim 13, wherein the channel has an opening extending in a longitudinal manner along at least a portion of the elongate shaft,

wherein a width of the opening is smaller than a diameter of the shaft of the medical device, and

wherein the wall of the elongate shaft is configured to flex to receive the shaft of the medical device through the longitudinally extending opening of the channel within the channel.

18. A medical device system comprising:

a hysteroscope comprising;

a longitudinally extending shaft, and

one or more lumens extending along at least a portion of the shaft; and

a sheath adapter comprising;

an elongate shaft extending from a proximal end to a distal end, a wall of the elongate shaft defining a channel having a longitudinally extending lateral opening, and

a lumen extending at least partially along a length of the elongate shaft and within the wall of the shaft, the lumen having a first port disposed proximate the distal end of the elongate shaft and a second port disposed proximate the proximal end of the elongate shaft,

wherein the hysteroscope shaft is configured to fit within the channel.

19. The medical device system of claim 18, wherein the shaft of the hysteroscope has an outer diameter and the channel of the sheath has an inner diameter, wherein the inner diameter of the channel is less than or equal to the outer diameter of the shaft of the hysteroscope.

20. The medical device sheath of claim 18, wherein a width of the longitudinally extending lateral opening of the channel is smaller than the shaft diameter of the hysteroscope, and wherein the wall of the elongate shaft is configured to flex to receive the shaft of the hysteroscope through the longitudinally extending lateral opening of the channel within the channel.
