Abstract:
1. A two-piece, separable hemostasis seal configured to permit passage of a medical device therethrough, the seal being generally cylindrical with a perimeter and a longitudinal axis and comprising: a first resilient seal portion including a first sealing member having a first mating surface oriented generally parallel to the longitudinal axis, a first projecting portion, and a first receiving portion; and a second resilient seal portion including a second sealing member having a second mating surface oriented generally parallel to the longitudinal axis, a second projecting portion, and a second receiving portion, wherein the first and second sealing members each have a first thickness near the perimeter and a second thickness near the longitudinal axis, and the first and second projecting portions have a third thickness near the perimeter and a fourth thickness near the longitudinal axis, wherein the first thickness is greater than the second thickness, and the third thickness is greater than the fourth thickness, and wherein, when the medical device is not positioned between the first and second resilient seal portions, the first mating surface mates with the second mating surface along its entire extent, and the first and second projecting portions mate with and sealingly engage the second and first receiving portions, respectively, along the entire extents thereof, and wherein, when the medical device is positioned between the first and second seal portions, the first and second mating surfaces form a first fluid seal with respect to the medical device via contact with the outer surface of the medical device, and the first and second projecting portions form a second fluid seal with the medical device via contact with the outer surface of the medical device; and wherein the first and second seal portions when mated define a proximal face having a generally conical concave cross-sectional profile including an apex at or near the longitudinal axis, and an opposite distal face having a concave cross-sectional profile and including a generally planar portion disposed about and generally orthogonal to the longitudinal axis.
