Abstract

A seal is provided for effectively inhibiting the egress of fluids from the working channel of an endoscope when an elongate device having a region with a non-circular cross-sectional shape is disposed therein. The seal has a body portion with a proximal end adapted for insertion of the elongate device, a distal end adapted for connection to the proximal end of the endoscope, and a wall defining a lumen adapted to receive the elongate device and to provide access to the working channel of the endoscope. The seal includes a sealing element for sealing the region of the elongate device with a non-circular cross-sectional shape. The sealing element conforms to the profile of the non-circular region.

Claims

1. A medical device system, comprising:

an endoscope including a channel formed in the endoscope; and

a sealing device comprising;

a seal body capable of attaching to the endoscope and to provide access to the channel formed in the endoscope; and

a seal disposed within the seal body, the seal being capable of sealing against a medical device extending through the seal body and into the channel.

2. The medical device system of claim 1, further comprising an elongate medical device extending through the sealing device and the endoscope.

3. The medical device system of claim 1, wherein the seal body includes an adapter that allows the seal body to be attached to a plurality of differently-sized endoscopes.

4. The medical device system of claim 2, wherein at least a portion of the medical device has a non-circular cross-sectional shape.

5. The medical device system of claim 2, wherein the medical device includes a catheter or a guidewire.

6. The medical device system of claim 1, wherein the seal includes a plurality of inward-projecting protrusions.

7. The medical device system of claim 2, wherein the seal includes a projection having a shape complementary to the non-circular cross-sectional shape of the medical device.

8. The medical device system of claim 1, wherein the seal body includes a clamp configured to engage a port on the endoscope.

9. The medical device system of claim 1, wherein the seal body further comprises means for applying a compressive force on the seal.

10. A medical device system, comprising:

an endoscope;

a seal attached to the endoscope;

an elongate medical device extending through the seal and the endoscope; and

a seal member disposed within the seal, the seal member being sealed against the medical device.

11. The medical device system of claim 10, wherein the seal member includes a foam disk.

12. The medical device system of claim 10, wherein the medical device includes a catheter or a guidewire.

13. The medical device system of claim 10, wherein at least a portion of the medical device has a non-circular cross-sectional shape.

14. The medical device system of claim 10, wherein the seal member includes a plurality of inward-projecting protrusions.

15. A sealing device for use with a medical device and an endoscope, the sealing device comprising:

a seal body configured for attachment to an endoscope and to provide access to a channel formed in the endoscope; and

a seal disposed within the seal body, the seal being configured to seal against a medical device extending through the seal body and into the channel.

16. The sealing device of claim 15, wherein the seal body includes an adapter that allows the seal body to be attached to a plurality of differently-sized endoscopes.

17. The sealing device of claim 15, wherein at least a portion of the medical device has a non-circular cross-sectional shape.

18. The sealing device of claim 15, wherein the seal includes a plurality of inward-projecting protrusions.

19. The sealing device of claim 15, wherein the seal body includes a clamp configured to engage a port on the endoscope.

20. The sealing device of claim 15, wherein the seal body further comprises means for applying a compressive force on the seal.
