Abstract

A splittable medical valve is disclosed that is configured with an interfacing region that permits the valve to be placed over or inside of a tubular medical device, such as a splittable introducer sheath, to prevent loss of bodily fluids and/or reduce ingress of air-borne pathogens. The valve further includes a sealing element configured to accept passage of a medical device, such as a catheter, sheath, pacemaker lead, or other ancillary device therethrough, whereby the valve body is split along one or more lines or fissure to allow removal of the valve from around the ancillary device.
