Abstract
Apparatus for introducing a catheter percutaneously into the body of a living being. The apparatus comprises a tubular member having a distal end portion and a proximal end portion. The proximal end portion is in the form of a hollow housing for a hemostatic valve assembly comprising a lubricant reservoir and a valve element. The reservoir is formed of a foam material impregnated with a lubricant liquid, e.g., silicone. The valve element is a disk-like member formed of resilient material, e.g., silicone impregnated with polydimethylsiloxane, located distally of the reservoir and has a openable passageway extending through it for the catheter to pass. The reservoir applies the lubricating fluid-in a controlled manner onto the catheter as it is passed through it, to thereby facilitate the passage of the catheter through the openable passageway in the valve element. The hollow housing is arranged to produce peripheral pressure on the valve element to facilitate its closure.
