Hemostasis valves and methods for making and using hemostasis valves
Hemostasis valves and methods for making and using hemostasis valves are disclosed. An example hemostasis valve may include a main body having a distal end region and a proximal end region. A first seal member may be disposed within the proximal end region of the main body. A cartridge may be at least partially disposed within the proximal end region of the main body. The cartridge may include a second seal member. The cartridge may have one or more projections formed thereon. The proximal end region of the main body may have one or more recesses formed therein. The one or more recesses may be designed to engage the one or more projections. A plunger may be coupled to the proximal end region of the main body.
1. A hemostasis valve, comprising:
a main body having a distal end region and a proximal end region;
a cartridge at least partially disposed within the proximal end region of the main body, the cartridge including a first seal member;
a second seal member disposed within the proximal end region of the main body;
wherein the cartridge has one or more projections formed thereon;
wherein the proximal end region of the main body has one or more recesses formed therein, the one or more recesses being designed to engage the one or more projections;
wherein the proximal end region of the main body includes one or more external threads;
a nut threadably engaged with the one or more external threads; and
a plunger coupled to the proximal end region of the main body, adjacent the nut.
2. The hemostasis valve of claim 1 , wherein the one or more recesses comprise one or more grooves formed along an inner surface of the proximal end region of the main body.
3. The hemostasis valve of claim 1 , wherein the one or more recesses comprise one or more slots formed along the proximal end region of the main body.
4. The hemostasis valve of claim 1 , wherein engagement of the one or more projections with the one or more recesses is designed to limit rotation of the cartridge relative to the proximal end region of the main body.
5. The hemostasis valve of claim 1 , further comprising a ring member disposed along an outer surface of the proximal end region of the main body.
6. The hemostasis valve of claim 1 , wherein the cartridge includes two projections positioned along opposing sides of the cartridge.
7. The hemostasis valve of claim 1 , wherein the proximal end region of the main body includes two recesses.
8. A hemostasis valve, comprising:
a main body having a distal end region, a side port, and a proximal end region;
a high pressure seal member disposed within the proximal end region of the main body;
a cartridge at least partially disposed within the proximal end region of the main body, the cartridge including a low pressure seal member;
wherein the cartridge has one or more projections formed thereon;
wherein the proximal end region of the main body has one or more recesses formed therein, the one or more recesses being designed to engage the one or more projections so as to limit rotation of the cartridge relative to the proximal end region of the main body;
wherein the proximal end region of the main body includes one or more external threads;
a nut threadably engaged with the one or more external threads; and
a plunger coupled to the proximal end region of the main body, adjacent the nut.
9. The hemostasis valve of claim 8 , wherein the one or more recesses comprise one or more grooves formed along an inner surface of the proximal end region of the main body.
10. The hemostasis valve of claim 8 , wherein the one or more recesses comprise one or more slots formed along the proximal end region of the main body.
11. The hemostasis valve of claim 8 , wherein the cartridge includes two projections positioned along opposing sides of the cartridge.
12. The hemostasis valve of claim 8 , wherein the proximal end region of the main body includes two recesses.
13. A hemostasis valve, comprising:
a main body having a threaded proximal end region;
a nut threadably engaged with the threaded proximal end region;
a cartridge at least partially disposed within the threaded proximal end region of the main body, the cartridge including a first seal member;
a second seal member disposed within the threaded proximal end region of the main body;
wherein the cartridge has a pair of opposing projections formed thereon; and
wherein the threaded proximal end region of the main body has a pair of opposing recesses formed therein, the recesses being designed to engage the projections so as to limit rotation of the cartridge relative to the threaded proximal end region of the main body.
14. The hemostasis valve of claim 13 , wherein the recesses comprise grooves formed along an inner surface of the threaded proximal end region of the main body.
15. The hemostasis valve of claim 13 , wherein the recesses comprise slots formed along the threaded proximal end region of the main body.
16. The hemostasis valve of claim 13 , further comprising a plunger coupled to the threaded proximal end region of the main body.
17. The hemostasis valve of claim 13 , wherein the second seal member comprises a high pressure seal.
18. The hemostasis valve of claim 13 , wherein the first seal member comprises a low pressure seal with at least one cut, slit, or slot formed therein.
