Abstract

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.
