Abstract: The detachable balloon catheter assembly comprises a balloon and sealing valve assembly including a sealing valve being formed of a resilient material having an elongate passageway extending therethrough and being mounted in a sleeve, an inflatable balloon having a mouth portion which is bonded to the sealing valve, and a small diameter cannula having a distal end which extends through the passageway in the sealing valve. The small diameter cannula includes a connector terminal on the proximal end which is adapted to be coupled to a source of fluid pressure. The passageway in the sealing valve takes the form of an elongate slit prior to insertion of the small diameter cannula through the passageway, and upon insertion of the cannula through the passageway, the passageway takes the form of a cylindrical aperture which is in fluid-tight engagement with the outer surface of the cannula while allowing the cannula to easily slide through the passageway.

Abstract: Disclosed is a plug or closure for sealing the electrical terminal block of a cardiac pacing device from contact with body fluids while allowing access to the terminal block when the closure is in place. The closure is made of an elastomeric material and includes an upper surface containing a first concave region and a lower surface including a second concave region. The concave surfaces are connected by a self-sealing transverse slit to insure a tight seal when the plug is seated under compression within the pacing device and also to permit access to a set screw contained in the electrical terminal block when the plug is in place. Such access permits adjustment of the set screw or electrical testing while the plug is seated.
