Abstract
A manifold connector, sheath connector and housing connector are provided for independently connecting a fiber enclosing sheath and (laser enhanced) fiber optic catheter housing to a transluminal balloon catheter manifold. The housing connector includes a locking plate enclosure, and a planar locking plate contained in the enclosure to reciprocate between open and locking positions, and spring biased into the locking position. The sheath connector includes an elongate cylindrical body attached to the distal end of the sheath, a disc extended radially outward of the body, and a sleeve extended forwardly of the disc perimeter and coaxial with the body. Two elongate levers also are mounted to the disc perimeter, and normally are aligned with the sleeve. A detent extends radially inward from the distal end of each lever. The manifold connector has an annular groove formed in its exterior, which is positionable to receive a locking blade portion of the locking plate, thus to form an interlocking engagement of the housing connector and manifold connector. An annular recess, formed in the manifold connector behind the annular groove, receives and retains the detents when the sheath connec…
