Abstract

The present invention provides a medical system including a protective sleeve for a medical device having a distal end positionable in a blood vessel, the protective sleeve including a body defining a passage therethrough and a vent in fluid communication with the passage, where at least a portion of the distal end of the medical device is positionable within the passage. An introducer device may be included having a sheath, where the sheath defines a first passage for receiving a portion of the catheter. In addition, the sleeve may be releasably engageable with the introducer device for subsequent insertion of the medical device into the introducer device.

Claims

1. An accessory sleeve for a medical device having a distal end positionable in a blood vessel, the accessory sleeve comprising:

a body defining a first opening, a second opening, and a passage extending from the first opening to the second opening, wherein the body defines a vent in fluid communication with the passage, wherein the body is substantially rigid, and wherein at least a portion of the distal end of the medical device is positionable within the passage.

2. The accessory sleeve according to claim 1, wherein the body defines a lip proximate the first opening, and wherein the vent is an opening in the lip.

4. The accessory sleeve according to claim 1, wherein the body defines a bezel tip proximate the first opening.

5. The accessory sleeve according to claim 1, further comprising a port in fluid communication with the passage.

6. The accessory sleeve according to claim 5, wherein the port includes a protrusion extending from the body, the protrusion defining a channel in fluid communication with the passage.

7. The accessory sleeve according to claim 1, further comprising a layer of material having a low coefficient of friction disposed about at least a portion of the passage.

8. The accessory sleeve according to claim 1, wherein the body is substantially transparent.

3. (canceled)

9. A medical device, comprising:

an elongate body defining a proximal end, a distal end, and a fluid flow path therethrough;

an inflatable element coupled to the distal end of the elongate body in fluid communication with the fluid flow path; and

a sleeve defining a first opening, a second opening, and a passage extending from the first opening to the second opening, wherein the sleeve defines a vent in fluid communication with the passage, wherein the sleeve is substantially rigid, and wherein at least a portion of the inflatable element is positionable within the passage.

10. The medical device according to claim 9, wherein the sleeve defines a lip proximate the first opening, and wherein the vent is an opening in the lip.

12. The medical device according to claim 9, wherein the sleeve defines a port in fluid communication with the passage.

13. The medical device according to claim 12, wherein the port includes a protrusion extending from the sleeve, the protrusion defining a channel in fluid communication with the passage.

20. The medical device according to claim 13, wherein a substantial portion of the second passage is concentric with a portion of the first passage upon releasable engagement of the sleeve to the introducer device.

11. (canceled)

14. A medical device for use with a catheter, comprising:

an introducer device having a sheath, wherein the sheath defines a first passage for receiving a portion of the catheter; and

a substantially rigid sleeve defining a first opening, a second opening, and a second passage extending from the first opening to the second opening, wherein the sleeve defines a vent in fluid communication with the passage, wherein at least a portion of the catheter is positionable within the passage, and wherein the sleeve is releasably engageable with the introducer device to place the second passage in fluid communication with the first passage.

15. The medical device according to claim 14, wherein the introducer device includes a valve disposed within the first passage.

16. The medical device according to claim 14, wherein the sleeve defines a lip proximate the first opening, and wherein the vent is an opening in the lip.

18. The medical device according to claim 14, wherein the sleeve defines a port in fluid communication with the passage.

19. The medical device according to claim 18, wherein the port includes a protrusion extending from the sleeve, the protrusion defining a channel in fluid communication with the passage.

17. (canceled)

21. A method of performing a medical procedure, comprising the steps of:

slidably positioning a portion of a medical device into a passage of a substantially rigid sleeve;

releasably engaging the sleeve with an introducer device, where the releasable engagement between the sleeve and the introducer element defines a vent; and

slidably inserting a portion of the medical device into the introducer device.

22. The method according to claim 21, wherein the medical device is a catheter having one or more inflatable elements disposed thereon.

23. The method according to claim 21, wherein the introducer device includes a sheath able to receive a portion of the medical device therein.

24. The method according to claim 21, wherein the step of releasably engaging the sleeve with the introducer device includes positioning a substantial portion of the passage concentric to an opening of the introducer device.
