Abstract

A wire guide holder having a wire guide deflector. The wire guide holder is provided with a securing portion and a deflecting portion. The securing portion is provided with protrusions and/or grooves for securing a distal portion of a wire guide against longitudinal movement. The deflecting portion is configured to direct the proximal end of a wire guide into an unobtrusive position. A frictional element may be provided to prevent the wire guide from inadvertently sliding or falling out of the deflecting portion. The wire guide holder may be attached to a medical scope or a bite block. The wire guide holder may also be provided with a seal.

12. The wire guide holder of claim 9 wherein the securing portion comprises a plurality of grooves extending inwardly into the body, the plurality of grooves being configured to permit an intermediate portion of the first elongate medical device to be woven there through so as to secure a distal portion of the first elongate medical device against longitudinal movement relative to the second medical device.

13. The wire guide holder of claim 1 wherein the passageway is configured to deflect a proximal portion of the first elongate medical device at an angle greater than 45 degrees relative to one of the body and the second elongate medical device.

14. The wire guide holder of claim 1 wherein the passageway is configured to deflect a proximal portion of the first elongate medical device at an angle greater than 90 degrees relative to one of the body and the second elongate medical device.

15. The wire guide holder of claim 1 wherein the first elongate medical device comprises a wire guide and the second elongate medical device comprises an endoscope.

16. The wire guide holder of claim 1 wherein the passageway comprises a lumen extending at least partially through an interior portion of the body.

17. The wire guide holder of claim 1 wherein the passageway comprises one of a channel or a clip disposed on an exterior surface of the body.

18. A wire guide holder for securing a first elongate medical device relative to a second medical device, the wire guide holder comprising:

a body having a passageway configured to deflect a proximal portion of the first elongate medical device relative to the second medical device; and

a securing element configured to limit longitudinal movement of a distal portion of the first elongate medical device relative to the second medical device.

19. The wire guide holder of claim 18, wherein the body comprises a spine and the passageway extends through the spine.

20. The wire guide holder of claim 19, wherein the securing element comprises a plurality of projections extending outwardly from the spine, the plurality of projections being configured to permit an intermediate portion of the first elongate medical device to be woven there through so as to secure the distal portion of the first elongate medical device against longitudinal movement relative to the second medical device.

21. The wire guide holder of claim 18 wherein the passageway comprises a means for inhibiting the movement of the proximal portion of the first elongate medical device when disposed there through.

22. The wire guide holder of claim 21 wherein the means for inhibiting the movement of the proximal portion of the first elongate medical device comprises one or more elastomeric devices extending at least partially into the passageway.

23. The wire guide holder of claim 21 wherein the means for inhibiting the movement of the proximal portion of the first elongate medical device comprises a non-linear passageway.

24. The wire guide holder of claim 18 further comprising an attachment portion configured for attachment to a second elongate medical device.
