Abstract

An apparatus and method for introducing portals into bone is described herein. An example apparatus for introducing portals into bone includes a handle, a base, and a driving member. The driving member can be made to project past the base by operating the handle. The base is detachable from the handle. The apparatus also includes a guide coupled at a first end to the handle and at a second end to the base. The base is detachably coupled to the guide. A base coupling detachably coupling the base to the guide includes an actuating member movable between a coupled configuration wherein the base is coupled to the guide and an uncoupled configuration wherein the base is released from the guide. The actuating member is arranged so that motion of the handle toward the base moves the actuating member from the coupled configuration to the uncoupled configuration.

Claims

1. An infusion tube assembly comprising:

a bone portal;

a flexible infusion tube having a first end coupled to the bone portal and a second end;

a fitting member coupled to the second end of the flexible infusion tube; and

a strain relief member secured to the fitting member, wherein the strain relief member comprises a hole through a portion of the strain relief member, the infusion tube passing through the hole and the portion of the strain relief member engages a circumferential groove in the fitting member.

2. An infusion tube assembly according to claim 1 wherein the fitting member is larger in diameter than the flexible infusion tube.

3. An infusion tube assembly according to claim 1 wherein a section of the bone portal is fitted inside a bore of the flexible infusion tube at the first end and the bone portal is secured to the first end of the flexible infusion tube by a collar swaged around the first end of the flexible infusion tube.

4. An infusion tube assembly according to claim 3 wherein the section of the bone portal is barbed.

5. An infusion tube assembly according to claim 4 wherein the section of the bone portal comprises a plurality of graduated barbs.

6. An infusion tube assembly according to claim 3 wherein the bone portal comprises a bone stop and the bone portal is secured to the first end of the flexible infusion tube at a location close to the bone stop.

7. An infusion tube assembly according to claim 1 wherein the bone portal is shorter in length than the flexible infusion tube.

8. An infusion tube assembly according to claim 1 wherein the strain relief member is made from an elastic material.

9. An infusion tube assembly according to claim 1 in combination with a base removably attachable to a subject, the base comprising a strain relief fitting adapted to releasably retain the strain relief member.

10. An infusion tube assembly according to claim 9 wherein the base is stiff.

11. An infusion tube assembly according to claim 9 wherein the base comprises a guiding aperture dimensioned to receive the bone portal and flexible infusion tube.

12. An infusion tube assembly according to claim 11 wherein the strain relief fitting comprises a hook.

13. An infusion tube assembly according to claim 12 wherein the strain relief member has an aperture and the hook is dimensioned to pass through the aperture.

14. An infusion tube assembly according to claim 13 wherein the hook comprises a resilient arm spaced apart from a surface on the base, the resilient arm having a free end, a fixed end and a portion between the fixed end and the free end in which a side of the arm facing the surface of the base projects towards the surface of the base relative to a tip of the free end.

15. An infusion tube assembly according to claim 14 wherein the strain relief fitting further comprises a pair of guide members projecting from the base, wherein the hook is between the guide members.

16. An infusion tube assembly according to claim 15 wherein the base further comprises a guide feature arranged to indicate a desired alignment of the base with an anatomical landmark of the subject.

17. An infusion tube assembly according to claim 16 wherein the guide feature is complementary to the anatomical landmark.

18. An infusion tube assembly according to claim 12 wherein the hook comprises a resilient arm spaced apart from a surface on the base, the resilient arm having a free end, a fixed end and a portion between the fixed end and the free end in which a side of the arm facing a support surface projects towards the support surface relative to a tip of the free end.

19. An infusion tube assembly according to claim 18 wherein the strain relief fitting further comprises a pair of guide members projecting from the base, wherein the hook is between the guide members.

20. An infusion tube assembly according to claim 19 wherein the base further comprises a guide feature arranged to indicate a desired alignment of the base with an anatomical landmark of the subject.

21. An infusion tube assembly according to claim 20 wherein the guide feature is complementary in shape to the anatomical landmark.

22. An infusion tube assembly according to claim 1 in combination with an adhesive patch removably attachable to a skin of the subject, the adhesive patch carrying a strain relief fitting adapted to releasably couple to the strain relief member.
