Abstract

Hemostasis valves and methods for making and using hemostasis valves are disclosed. An example hemostasis valve may include a main body having a proximal end region. A cartridge may be at least partially disposed within the proximal end region. The cartridge including a seal member. The cartridge may have a proximal member, a distal member, and may define a seal holding region. The seal member may have an axial thickness of about 0.04 to about 0.2 inches. The seal member may be secured within the seal holding region by a mechanical bond.

First claim

What is claimed is:

1 . A hemostasis valve, comprising:
a main body having a proximal end region; a cartridge at least partially disposed within the proximal end region, the cartridge including a seal member; wherein the cartridge has a proximal member, a distal member, and defines a seal holding region; wherein the seal member has an axial thickness of 0.04-0.2 inches; and wherein the seal member is secured within the seal holding region by a mechanical bond.

2 . The hemostasis valve of claim 1 , wherein the mechanical bond includes a crimp.

3 . The hemostasis valve of claim 1 , wherein the seal member has an axial thickness of 0.075-0.095 inches.

4 . The hemostasis valve of claim 1 , wherein the seal member has a distal face with a distal slit, wherein the seal member has a proximal face with a proximal slit; and wherein the distal slit and the proximal slit are axially spaced 0.01-0.02 inches.

5 . The hemostasis valve of claim 4 , wherein the distal slit is arranged orthogonally with the proximal slit.

6 . The hemostasis valve of claim 1 , further comprising a plunger coupled to the proximal end region of the main body.

7 . The hemostasis valve of claim 1 , wherein the seal member has a seal body and a peripheral region designed to engage the seal holding region of the cartridge.

8 . The hemostasis valve of claim 7 , wherein the peripheral leg region has a radial thickness of 0.001-0.02 inches.

9 . The hemostasis valve of claim 7 , wherein the central seal region has a width that is at least twice as large as a radial thickness of the peripheral leg region.

10 . The hemostasis valve of claim 1 , wherein the proximal end region of the main body includes one or more threads and further comprising a nut threadably engaged with the one or more threads.

11 . A hemostasis valve, comprising:
a main body having a threaded proximal end region; a nut threadably engaged with the threaded proximal end region; a plunger coupled to the threaded proximal end region; a cartridge at least partially disposed within the threaded proximal end region, the cartridge including a seal member; wherein the seal member is secured within a seal holding region of the cartridge by a mechanical bond; and wherein the seal member has an axial thickness of 0.04-0.2 inches.

12 . The hemostasis valve of claim 11 , wherein the mechanical bond includes a crimp.

13 . The hemostasis valve of claim 11 , wherein the seal member has an axial thickness of 0.075-0.095 inches.

14 . The hemostasis valve of claim 11 , wherein the seal member has a distal face with a distal slit, wherein the seal member has a proximal face with a proximal slit; and wherein the distal slit and the proximal slit are axially spaced 0.01-0.02 inches.

15 . The hemostasis valve of claim 14 , wherein the distal slit is arranged orthogonally with the proximal slit.

16 . The hemostasis valve of claim 11 , wherein the seal member has a central seal region and a peripheral leg region designed to engage the seal holding region of the cartridge.

17 . The hemostasis valve of claim 16 , wherein the peripheral leg region has a radial thickness of 0.001-0.02 inches.

18 . The hemostasis valve of claim 16 , wherein the central seal region has a width that is at least twice as large as a radial thickness of the peripheral leg region.

19 . A hemostasis valve, comprising:
a main body having a threaded proximal end region; a nut threadably engaged with the threaded proximal end region; a plunger coupled to the threaded proximal end region; a cartridge at least partially disposed within the threaded proximal end region, the cartridge including a seal member; wherein the seal member is secured within a seal holding region of the cartridge by a crimp bond; wherein the seal member has a central seal region and a peripheral leg region designed to engage the seal holding region of the cartridge; and wherein the central seal region has a width that is at least twice as large as a radial thickness of the peripheral leg region.

20 . The hemostasis valve of claim 19 , wherein the seal member has an axial thickness of 0.075-0.095 inches.
