Abstract
The invention relates to a valve used in medical procedures. More specifically the invention relates to an introducer sheath valve used in minimally invasive and conventional surgical procedures. The valve may accommodate a wide range of surgical implement diameters, shapes, and multiple implements without imposing the high frictional forces of known valves.
Claims20
A valve comprising:
- an outer tube;
- an inner tube formed of a multi-layer construct;
- and
- a pressurizable space formed between an inner surface of the outer tube and an outer surface of the inner tube, the pressurizable space being configured to expand upon being pressurized and to expand via radially inward deflection of the inner tube and radially outward deflection of the outer tube.

An introducer sheath valve comprising:
- an outer tube having an inner surface and an outer surface, the outer tube formed of an elastomeric material;
- an inner tube having an inner surface and an outer surface, the inner tube formed of a multi-layer construct;
- a pressurizable space formed between the inner surface of the outer tube and the outer surface of the inner tube;
- and
- a connector fluidly coupled to the pressurizable space,
- wherein when the pressurizable space is pressurized, the outer tube distends radially outward from the inner tube to provide a visual indicator of pressurization and the inner tube collapses radially inward to form a seal.
3 more elements
A system comprising:
- a valve including,
- an outer tube having an inner surface and an outer surface;
- an inner tube having an inner surface and an outer surface, the inner tube formed of a multi-layer construct;
- and
- a pressurizable space formed between the inner surface of the outer tube and the outer surface of the inner tube,
- wherein the valve is transitionable between a non-pressurized state and a pressurized state in which the outer tube expands outwardly and the inner tube collapses inwardly;
- and
- an introducer sheath extending proximally from the introducer sheath valve.
