A topless catheter, which can be used as either a guiding catheter for guiding balloon dilatation catheters into a body lumen, or as a diagnostic catheter for conducting radio opaque dyes into a predetermined body lumen or both is disclosed. The topless catheter comprises a cylinderical catheter shaft, integrally connected to an arcuate topless guiding finger. The guiding finger is adapted for placement proximate to, or partially within a predetermined blood vessel for subselective placement of a dilation balloon catheter. By virtue of the manner in which the guiding finger is configured, blood flow through the more distal arteries is substantially unimpeded without detracting from the support and guidance features, found in conventional guiding catheters.

A guiding catheter for use in the diagnosis and treatment of arterial stenosis, constructed and arranged to (i) conduct radio opaque dyes into a predetermined blood vessel and (ii) guide a balloon dilation catheter into the blood vessel to relieve the stenosis, said guiding catheter comprising: an axially elongate cylindrical shaft, having a proximal end and a distal end; an open section having a uniform arcuate cross-sectional configuration along its length, said open section being integrally connected to said distal end of said shaft; and a soft tip, abutted against said open arcuate portion, and bonded thereto, said soft tip formed of a material substantially more malleable than that of said shaft.
