Abstract: A hemostasis valve assembly for use in a medical device. The hemostasis valve assembly may include a main body portion defining an internal cavity, a seal cartridge disposed within the internal cavity, and a low pressure valve assembly positioned within the internal cavity adjacent to the seal cartridge. The low pressure valve assembly may include a first valve member having a first valve body and a second valve member having second valve body. A portion of a distal side of the first valve member may abut at least a portion of a proximal side of the second valve member.

Abstract: A medical device that includes a clamp having a body defining a channel and a fixation member that is configured to move relative to the body from an unlocked position to a locked position. The medical device includes an actuator coupled to the fixation member and configured to move the fixation member from the unlocked position to the locked position. The fixation member extends at least partially into or radially outward from the channel in response to moving from the unlocked position to the locked position.

Abstract: A surgical method for providing or enlarging an operative space is described. The surgical method can employ a shell having inflatable ribs and generally planar non-inflatable segments spaced apart by the ribs. When inflated, the ribs support the planar segments of the shell to provide an expansion space above a tissue layer. Once the shell is in the inflated configuration, a vacuum can be provided through the shell to lift the tissue layer toward the shell.
