Abstract

Endoscope assemblies, biopsy caps, and methods for making and using the same. An example endoscope assembly may include an endoscope having a channel formed therein and a port that provides access to the channel. A cap may be coupled to the port. The cap may include a base and an outer shell. A locking member may be coupled to the outer shell. An inner seal member may be disposed within the outer shell. One or more openings may extend through the cap and into the channel. An actuator may be coupled to the base for shifting the inner seal member between an unsealed configuration and a sealed configuration.

Claims

6. An endoscope assembly, comprising:

an endoscope having a channel formed therein and a port that provides access to the channel; and

a cap coupled to the port, the cap including a base, an outer shell, a locking member coupled to the shell, an inner seal member disposed within the outer shell, one or more openings extending through the cap and into the channel, and an actuator coupled to the base for shifting the inner seal member between an unsealed configuration and a sealed configuration.

1. An endoscope biopsy cap, comprising:

a base portion for attaching the biopsy cap to an endoscope;

a body portion;

a compression seal member disposed within the body portion, wherein the compression seal member is configured to shift between a sealed configuration and an unsealed configuration; and

a collet coupled to the body portion.

2. The biopsy cap of claim 1, wherein the base portion includes a pair of clips and one or more ramped surfaces disposed adjacent the pair of clips.

3. The biopsy cap of claim 2, wherein the body portion includes threads and wherein the collet includes threads that are coupled with the threads of the body portion.

4. The biopsy cap of claim 3, wherein the body portion is rotatable relative to the collet.

5. The biopsy cap of claim 4, wherein the collet includes one or more ramped surfaces that are disposed adjacent the compression seal member, and wherein rotation of the body portion shifts the position of the collet such that the ramped surfaces urge the compression seal member radially inward.

7. The assembly of claim 6, further comprising a strain relief member extending out from the central opening.

8. The assembly of claim 7, wherein the strain relief member is a portion of the inner seal member.

10. The assembly of claim 6, wherein the outer shell includes a chuck that is configured to shift between a first position and a second position.

11. The assembly of claim 10, wherein the actuator shifts the chuck between the first position and the second position.

12. The assembly of claim 11, wherein the actuator includes a rotatable ring member coupled to the outer shell.

13. The assembly of claim 6, wherein the inner seal member includes a first seal region and a second seal region.

14. The assembly of claim 13, wherein the first seal region is configured to seal against the port.

15. The assembly of claim 13, wherein the second seal region is configured to seal against a device extending through the inner seal member.

16. The assembly of claim 6, wherein the inner seal member is deformable within the shell.

17. The assembly of claim 16, wherein the unsealed configuration is a non-twisted configuration, and wherein the sealed configuration is a twisted configuration.

8-1. The assembly of claim 6, wherein the inner seal member includes one or more sets of overlapping flaps.

18. An endoscope biopsy cap, comprising:

an outer shell having an opening formed therein and a base;

a locking member coupled to the outer shell for securing the position of a medical device disposed in the opening;

an inner seal member disposed within the outer shell; and

an actuator coupled to the base for shifting the inner seal member between an unsealed configuration and a sealed configuration.

19. The cap of claim 18, wherein the actuator includes a rotatable ring member coupled to the shell.

20. The cap of claim 18, wherein the inner seal member includes a first seal region and a second seal region, wherein the first seal region is configured to seal against the port, and wherein the second seal region is configured to seal against a device extending through the inner seal member.
