Abstract: A device for simulating catheterization in a body channel of a patient comprising, a catheter having an elongated shaft, an inflation balloon on the shaft, and an inflation lumen extending along the shaft and communicating with the balloon. The device has a sleeve of flexible material defining a cavity to receive the portion of the shaft containing the balloon, with the sleeve having a sufficiently small width such that the balloon contacts walls of the sleeve when inflated. The sleeve has a line of weakness which ruptures when the balloon is sufficiently inflated unless relieved of pressure prior to rupture of the sleeve.

Abstract: A manometer for recording maximum pressures from a liquid supply comprising, a closed air chamber, an elongated channel communicating with the supply adjacent a lower end of the channel and communicating with the chamber through an opening adjacent an upper end of the channel, and an overflow cavity positioned to receive and collect liquid passing through the channel and opening such that the quantity of liquid collected in the cavity provides an indication of the maximum pressure achieved by the supply.

Abstract: A hemostatic device comprising, a catheter having an elongated elastic shaft, an inflatable balloon adjacent a distal end of the shaft, and a sidearm adjacent a proximal end of the catheter. The device has a traction member comprising a retaining portion to receive the catheter shaft and sidearm, with the retaining portion being connected to an object to maintain the catheter shaft under selected tension.

Abstract: A catheter assembly comprising, a catheter having an elongated shaft, and an elongated sleeve of flexible material covering at least a substantial portion of the catheter. The sleeve has a pair of opposed first and second walls extending between a pair of opposed longitudinal fold lines at sides of the sleeve with the catheter being received between the walls in a generally flat configuration of the sleeve. The sleeve has a circumferential cuff of enlarged dimensions defining an open distal end of the sleeve.
