Patent ID: 8506534

Claim:
A hemostasis valve comprising: an elongate valve housing having a first port, a second port opposite the first port and a fluid path running between the first and second ports which is aligned to a longitudinal axis of the valve housing, the valve housing having a cylindrical straight portion and a conical portion; an occluder slideable within the housing between first and second positions, the occlunder having: a structural occluder ring slideable against the interior surface of the cylindrical straight portion of the elongate valve housing; a plurality of structural occlusion shafts each having distal end portion connected to the structural occlude ring and a free end portion; the free end portions of the occlusion shafts slideable against the interior surface of the conical portion of the elongate valve housing, the free end portions collectively forming a plug configured to fit within the first port to occlude the first port when the occluder is in the first position, the proximal end portions being closer to the first port than the structural occluder ring; wherein the structural occlusion shafts are forced apart from each other when the occluder is in the second position to spread open the proximal end portions of the occlusion shafts and allow fluid to flow through the first port.
