First Claim
1. A testing device for testing the sealing strength of a seal in a catheter sheath introducer comprising:
- means for receiving the introducer;
means for supplying pulsating liquid to the inside of the introducer; and
means for controlling the upper and lower pressures of the fluid supplied to the introducer while observing the sealing strength of the seal, with or without an elongate, rod-like member received therein.

Abstract
The treating device for testing the sealing strength of a seal in a catheter sheath introducer comprises a port for receiving the introducer, a mechanism for supplying pulsating liquid to the inside of the introducer, and controls for controlling the upper and lower pressures of the fluid supplied to the introducer while observing the sealing strength of the seal, with or without an elongate, rod-like member received therein. The method for testing the sealing strength of the fluid seal within a catheter sheath introducer including the steps of providing a port for engaging said introducer; engaging the introducer to the port in a fluid tight manner; supplying a pulsating flow of fluid to the inside of the introducer; controlling the upper and lower pressure parameters for the flowing fluid; and observing the seal for leakage.

18. A device for testing the sealing strength of fluid passageway seals of a catheter sheath introducer comprising:
-
a fluid container; a closed fluid system including an outflow fluid pathway from said container; means for connecting the outflow fluid pathway to an entrance tube portion of the passageway in the introducer; a return fluid pathway to said container; means for connecting the return fluid pathway to a side port of the introducer; means for creating a flow of fluid through said system; means for causing pulsation of said fluid flow between a predetermined high level of fluid pressure and a predetermined low level of fluid pressure; means for regulating said high and low predetermined pressure levels; and means for supplying electrical current to said device.
