Abstract

An access valve (2) for a laparoscopic device or a intraluminal deployment device has a cylindrical diaphragm (8) with a longitudinal aperture (3), a flexible member (14) is passed circumferentially around the cylindrical diaphragm and an extension arrangement to pull the flexible member radially and/or tangentially to constrict the diaphragm to at least partially close o ff the longitudinal aperture. A rotary actuator may be used (12).

Claims (10)

1. An access valve having a cylindrical diaphragm in a substantially cylindrical housing with a longitudinal aperture through the cylindrical diaphragm, the cylindrical diaphragm being formed from a resilient material, a flexible member passed circumferentially around the cylindrical diaphragm at least for one full turn, apertures in the cylindrical housing through which the flexible member extends and a rotary actuator on the cylindrical housing with respective ends of the flexible member joined to the rotary actuator whereby rotation of the rotary actuator with respect to the cylindrical housing causes the flexible member to be pulled through the apertures to constrict the diaphragm to at least partially close off the longitudinal aperture.
2. An access valve as in Claim 1 wherein the rotary actuator is retained in position on the cylindrical housing by the flexible member extending from the rotary actuator to the cylindrical diaphragm through the apertures in the cylindrical housing.
3. An access valve as in Claim 1 wherein the rotary actuator is retained in position on the cylindrical housing by a radial flange on the cylindrical housing or on the cylindrical diaphragm.
4. An access valve as in Claim 1 wherein the cylindrical diaphragm is constructed from a silicone rubber.
5: An access valve as in Claim 1 wherein the flexible member is a string, suture or band or other suitable material.
6. An access valve as in Claim 1 further including a recessed region on the cylindrical diaphragm to act as a guide for the flexible member.
7. An access valve as in Claim 2 further including a ball and detent arrangement between the rotary actuator and the cylindrical housing whereby tactile feel of the action of the rotary actuator is provided.
8. An access valve as in Claim 1 mounted onto an access location of a laparoscopic device.
9. An access valve as in Claim 1 mounted onto a prosthesis delivery device.
10. An access valve as in Claim 1 further including an additional apertured diaphragm seal in the valve to assist with a sealing action.
