Abstract

An intraluminal catheter (24) for directing a guidewire (26) and/or catheter (26a) in a desired direction within a bodily vessel or cavity. The intraluminal catheter (24) has a first elongate tubular member (52) and a support means which can comprise a second elongate tubular member (51) that can pass over a main support guidewire (23). The catheter (24) acts as a platform as the guidewire (26) is passed through the first elongate tubular member (52) and is deflected transversely outwardly by an angled surface (54) through an aperture (50). A
second intraluminal catheter (60) has a first elongate tubular member (63) and a support means comprising a second elongate tubular member (61). The first elongate tubular member (63) has a main portion (65) and an end portion (66), with the end portion (66) being deflectable relative to the locus of the main portion so as to direct the guidewire (26) passing through the end portion (66) in a desired direction in the bodily vessel.
