Abstract

Hemostasis valves and methods for making and using hemostasis valves are disclosed. An example method for assembling a hemostasis valve may include positioning a plunger along a threaded proximal end region of a main body. The threaded proximal end region may include one or more threads and an axial slot extending through the one or more threads. The method may also include advancing the plunger along the threaded proximal end region to a position where a proximal end of the plunger is disposed distally of at least a portion of the one or more threads and disposing a nut adjacent to the threaded proximal end region. The method may also include aligning an alignment tab of the nut with the axial slot, engaging the nut with the one or more threads while the alignment tab is aligned with the axial slot, and rotating the nut 45-270°.

First claim

What is claimed is:

1 . A method for assembling a hemostasis valve, the method comprising:
positioning a plunger along a threaded proximal end region of a main body; wherein threaded proximal end region of the main body includes one or more threads and an axial slot extending through the one or more threads; advancing the plunger along the threaded proximal end region of the main body to a position where a proximal end of the plunger is disposed distally of at least a portion of the one or more threads; disposing a nut adjacent to the threaded proximal end region of the main body, the nut having an alignment tab formed thereon; aligning the alignment tab with the axial slot; engaging the nut with the one or more threads while the alignment tab is aligned with the axial slot; and rotating the nut 45-270° relative to the threaded proximal end region of the main body.

2 . The method of claim 1 , further comprising disposing a first seal member within the threaded proximal end region of the main body.

3 . The method of claim 1 , further comprising disposing a cartridge at least partially within the threaded proximal end region of the main body, the cartridge including a second seal member.

4 . The method of claim 3 , wherein rotating the nut 45-270° relative to the threaded proximal end region of the main body engages the nut with the cartridge.

5 . The method of claim 1 , further comprising moving the plunger proximally relative to the threaded proximal end region of the main body.

6 . The method of claim 5 , further comprising disposing a spring within the plunger.

7 . The method of claim 6 , further comprising securing a plunger cap to the plunger.

8 . The method of claim 1 , wherein the threaded proximal end region of the main body has a first locking indicator.

9 . The method of claim 8 , wherein the plunger includes a second locking indicator and wherein positioning a plunger along a threaded proximal end region of a main body includes aligning the first locking indicator with the second locking indicator.

10 . The method of claim 1 , wherein rotating the nut 45-270° relative to the threaded proximal end region of the main body includes rotating the nut 90-180° relative to the threaded proximal end region of the main body.

11 . The method of claim 1 , wherein rotating the nut 45-270° relative to the threaded proximal end region of the main body includes rotating the nut 180° relative to the threaded proximal end region of the main body.

12 . A method for assembling a hemostasis valve, the method comprising:
advancing a plunger along a threaded proximal end region of a main body; wherein the threaded proximal end region has one or more threads and an axial slot; wherein advancing the plunger along a threaded proximal end region of a main body includes advancing the plunger to a position where a proximal end of the plunger is disposed distally of at least a portion of the one or more threads; engaging a nut with the threaded proximal end region of the main body, the nut having an alignment tab formed thereon; aligning the alignment tab with the axial slot; and rotating the nut 90-180° relative to the threaded proximal end region of the main body.

13 . The method of claim 12 , further comprising disposing a first seal member within the threaded proximal end region of the main body and further comprising disposing a cartridge at least partially within the threaded proximal end region of the main body, the cartridge including a second seal member.

14 . The method of claim 13 , wherein rotating the nut 45-270° relative to the threaded proximal end region of the main body engages the nut with the cartridge.

15 . The method of claim 12 , further comprising moving the plunger proximally relative to the threaded proximal end region of the main body.

16 . The method of claim 15 , further comprising disposing a spring within the plunger and securing a plunger cap to the plunger.

17 . The method of claim 12 , wherein the threaded proximal end region of the main body has a first locking indicator, wherein the plunger includes a second locking indicator, and wherein positioning a plunger along a threaded proximal end region of a main body includes aligning the first locking indicator with the second locking indicator.

18 . The method of claim 12 , wherein rotating the nut 90-180° relative to the threaded proximal end region of the main body includes rotating the nut 180° relative to the threaded proximal end region of the main body.

19 . A method for assembling a hemostasis valve, the method comprising:
disposing a cartridge at least partially within a threaded proximal end region of a main body; wherein the proximal end region of the main body has an axial slot formed therein; engaging a nut with the threaded proximal end region of the main body, the nut having an alignment slot formed therein; aligning the alignment slot with the axial slot; rotating the nut 90-180° relative to the threaded proximal end region of the main body; and coupling a plunger to the main body.

20 . The method of claim 19 , wherein rotating the nut 90-180° relative to the threaded proximal end region of the main body includes rotating the nut 180° relative to the threaded proximal end region of the main body.
