Abstract
A device for use in withdrawing a catheter such as a balloon catheter from a vessel in the vascular system in order to inhibit damage to the vessel wall includes an assembly defining a passageway through which to pass the catheter. The assembly is dimensioned and arranged to be grasped by a user, and it includes components for coupling the assembly to the catheter so that the user can withdraw the catheter from the vessel by moving the assembly generally axially. The coupling components are adjustable to enable the user to select a desired maximum amount of force that can be coupled from the assembly to the catheter, and for this purpose one embodiment includes a cap-and-compressible-disk arrangement on a body member in which a spring-coupled handle member is telescopingly disposed, graduations along the handle member providing a visually discernible indication of relative handle member position and therefore of the magnitude of a force being coupled by the user to the assembly.
