Abstract

Claims (39)

1 . A method of manufacturing an irrigation sleeve, said method comprising:

forming a sleeve body between a proximal sleeve end and a distal sleeve end, the sleeve body having a first lumen and a second lumen spaced from the first lumen, the second lumen having a generally crescent-shaped profile;

positioning a shaft into the second lumen at the distal sleeve end; and

reforming the sleeve body around the shaft adjacent to the distal sleeve end to differentiate the second lumen into a distal lumen region having a cylindrical profile defined by the shaft and a proximal lumen region having the crescent-shaped profile.

2 . The method as set forth in claim 1 , further comprising:

providing a first mandrel assembly having an insertion guide shaped to support the shaft;

supporting the sleeve body with the first mandrel assembly; and

positioning the shaft into the insertion guide of the first mandrel assembly.

3 . The method as set forth in claim 1 , further comprising removing the shaft from the distal lumen region of the second lumen.

4 . The method as set forth in claim 1 , further comprising:

providing a second mandrel assembly having a conical region;

supporting the sleeve body with the second mandrel assembly; and

reforming at least a portion of the sleeve body adjacent to the distal sleeve end around the conical region of the second mandrel assembly.

5 . The method as set forth in claim 4 , further comprising removing at least a portion of the sleeve body adjacent to the distal sleeve end to define a lumen outlet in fluid communication with the distal lumen region.

6 . The method as set forth in claim 1 , wherein the proximal lumen region of the second lumen extends from a lumen inlet adapted for fluid communication with an irrigation source to a lumen transition, and the distal lumen region of the second lumen extends from the lumen transition to a lumen outlet arranged to direct fluid adjacent to a head of a cutting accessory, the proximal lumen region having a larger cross-sectional area than the distal lumen region taken at the lumen transition.

7 . The method as set forth in claim 6 , wherein the lumen transition defines a transition surface, and wherein the distal lumen region comprises a transition inlet defined in the transition surface such that the distal lumen region extends in fluid communication between the transition inlet and the lumen outlet.

8 . The method as set forth in claim 7 , wherein the lumen outlet is arranged between the lumen transition and the distal sleeve end.

9 . The method as set forth in claim 7 , wherein the lumen outlet is arranged at the distal sleeve end.

10 . The method as set forth in claim 7 , wherein the transition surface has an outer periphery defined at least partially by the generally crescent-shaped profile of the proximal lumen region.

11 . The method as set forth in claim 7 , wherein the proximal lumen region of the second lumen has a profile comprising a first lumen corner surface and a second lumen corner surface; and wherein the transition surface has a profile comprising a first transition corner surface arranged generally coincident with the first lumen corner surface of the proximal lumen region.

12 . A method of manufacturing an irrigation sleeve, said method comprising:

forming a sleeve body between a proximal sleeve end and a distal sleeve end, the sleeve body having a first lumen and a second lumen spaced from the first lumen;

positioning a shaft into the second lumen at the distal sleeve end; and

reforming the sleeve body around the shaft adjacent to the distal sleeve end to differentiate the second lumen into a distal lumen region having a cylindrical profile defined by the shaft and a proximal lumen region;

wherein the second lumen is spaced out of fluid communication with the first lumen.

13 . The method as set forth in claim 12 , further comprising:

providing a first mandrel assembly having an insertion guide shaped to support the shaft;

supporting the sleeve body with the first mandrel assembly; and

positioning the shaft into the insertion guide of the first mandrel assembly.

14 . The method as set forth in claim 12 , further comprising removing the shaft from the distal lumen region of the second lumen.

15 . The method as set forth in claim 12 , further comprising:

providing a second mandrel assembly having a conical region;

supporting the sleeve body with the second mandrel assembly; and

reforming at least a portion of the sleeve body adjacent to the distal sleeve end around the conical region of the second mandrel assembly.

16 . The method as set forth in claim 15 , further comprising removing at least a portion of the sleeve body adjacent to the distal sleeve end to define a lumen outlet in fluid communication with the distal lumen region.

17 . The method as set forth in claim 12 , wherein the proximal lumen region of the second lumen extends from a lumen inlet adapted for fluid communication with an irrigation source to a lumen transition, and the distal lumen region of the second lumen extends from the lumen transition to a lumen outlet arranged to direct fluid adjacent to a head of a cutting accessory, the proximal lumen region having a larger cross-sectional area than the distal lumen region taken at the lumen transition.

18 . The method as set forth in claim 17 , wherein the lumen transition defines a transition surface, and wherein the distal lumen region comprises a transition inlet defined in the transition surface such that the distal lumen region extends in fluid communication between the transition inlet and the lumen outlet.

19 . The method as set forth in claim 17 , wherein the lumen outlet is arranged between the lumen transition and the distal sleeve end.

20 . The method as set forth in claim 18 , wherein the transition surface has an outer periphery defined at least partially by a generally crescent-shaped profile of the proximal lumen region, and wherein the proximal lumen region of the second lumen has a profile comprising a first lumen corner surface and a second lumen corner surface; and wherein the transition surface has a profile comprising a first transition corner surface arranged generally coincident with the first lumen corner surface of the proximal lumen region.
