<p>A support catheter assembly (10) for facilitating medical procedures includes a tubular body and a continuous lumen from its proximal end to its distal end. A manipulating member is connected to the tubular body (12) for inserting, advancing, withdrawing and maneuvering the body during a medical procedure. The manipulating member may be a wire (14) of a manipulating tube (16). The tubular body also may be provided with a funnel shaped (26) lumen opening at its proximal end to facilitate insertion of devices therethrough, and radiopaque markers for subcutaneously detecting the location of the device during a medical procedure and, more particularly, for detecting its location relative to other devices used in the medical procedure. A method also is disclosed for using the tube assembly to facilitate insertion of a PTCA catheter into a stenotic region and for holding open the lumen through that region after angioplasty has been performed.</p> |
