Abstract
A sheath which contains a catheter or guide wire is provided with a connector at one end which, in turn, has a sealing membrane which can be pierced by a hollow needle when the catheter/guide wire is to be expelled from the adaptor assembly. An introducer, which is to be implanted in a body cavity such as a blood vessel, also has a hub with a sealing membrane disposed across the hub so as to abut the sealing membrane of the adaptor assembly. This membrane is also pierced by the hollow needle when the connection is made prior to insertion of a catheter or guide wire into the blood vessel. In one embodiment, a syringe may be provided with a connector and mounted on the hub of the introducer.
