Modular hemostatic valve
View Patent ↗A modular hemostatic valve includes a splittable valve body. The splittable body defines a passageway. A sealing element positions in the passageway. The sealing element is configured to facilitate the passage of a first medical device, and the splittable valve body is configured to engage a second medical device.
1. A modular hemostatic valve, comprising:
a splittable valve body, the splittable body defining a passageway; and
a sealing element positioned in the passageway,
wherein the sealing element is configured to facilitate the passage of a first medical device, and the splittable valve body has a first end and a second end,
a first splittable end lead capturing the first end of the splittable valve body, and a second splittable end lead capturing the second end of the splittable valve body, the first and second splittable end leads being spaced from each other and configured to retain the splittable valve body and sealing element as an assembled array,
the splittable valve body including longitudinal guide tracks allowing only axial assembly of the splittable end leads to the splittable valve body.
2. The modular hemostatic valve of claim 1 , wherein at least one of the splittable end leads further defines an interfacing region configured to engage a second medical device.
3. The modular hemostatic valve of claim 1 , wherein the splittable valve body comprises a first shell and a second shell connected to the first shell to form the passageway.
4. The modular hemostatic valve of claim 1 , wherein each of the splittable end leads further comprises an elongated protrusion for engagement with one of the longitudinal guide tracks.
5. The modular hemostatic valve of claim 1 , wherein each splittable end capturing an end of the splittable valve body comprises a first half member and a second half member connected to the first half member.
6. The modular hemostatic valve of claim 5 , wherein the first and second half members of the splittable end lead define a receiving chamber configured to capture an end of the splittable valve body.
7. The modular hemostatic valve of claim 2 , wherein the at least one splittable end lead further comprises a coupling component configured to facilitate the passage of the first medical device and a barbed lead configured to be captured by the second medical device.
8. The modular hemostatic valve of claim 1 , wherein the sealing element defines a slot configured to facilitate the passage of the first medical device.
9. The modular hemostatic valve of claim 1 , wherein the sealing element comprises of a material selected from a group consisting of silicone foam, viscous liquid glycerin, gel, sponge, densely packed minute beads and stripes of collagen.
10. The modular hemostatic valve of claim 1 , wherein the sealing element comprises of a shape selected from a group consisting of a longitudinally extending tube-shaped, a pill-shaped, a plug-shaped with seal rings or seam, and a solid tube with internal ripples.
11. A modular hemostatic valve comprising:
a shell having a distal end and a proximal end,
a passageway extending longitudinally through the shell between the proximal and distal ends;
a longitudinally extending sealing element positioned within the passageway, the sealing element having an intemal surface adapted to contact any medical device passing through the shell sufficiently to provide a barrier against fluid backflow though the shell,
the shell including a longitudinal hinge and a mating protrusion and hub permitting quick lateral disassembly from the medical device passing through the shell,
the shell further including a cylindrical interfacing region extending longitudinally from one end of the shell to surround and capture an end of a second medical device, the cylindrical interfacing region including a longitudinal guide track permitting only axial coupling of the second medical device to the cylindrical interfacing region.
12. The modular hemostatic valve of claim 11 wherein the sealing element has an end extending into the cylindrical interfacing region of the shell.
13. The modular hemostatic valve of claim 11 , wherein the sealing element comprises of a primary sealing member and a secondary sealing member separated from the primary sealing member by an intermediate wall.
14. The modular hemostatic valve of claim 13 , wherein the secondary sealing member further comprises a lateral groove leading to a side port.
15. The modular hemostatic valve of claim 11 , further comprising a side port in fluid communication with the passageway, the side port being configured to engage a third medical device.
