Abstract
The present invention relates to a surgical catheter, and more particularly, a balloon catheter having an auxiliary lumen configured to permit the advancement of a functional measurement wire to a treatment site. The auxiliary lumen communicates with a working lumen that is configured to permit the advancement of a guidewire and the functional measurement wire, so that the guidewire and functional measurement wire may selectively be advanced to the treatment site during a surgical procedure.
Claims12
A catheter for use with a wire for therapeutic or diagnostic applications, the catheter comprising:
- an outer tube having proximal and distal ends;
- an inner tube having proximal and distal ends and a working lumen extending therethrough, the inner tube being disposed within the outer tube;
- an auxiliary tube having proximal and distal ends, an auxiliary lumen extending therethrough, the auxiliary lumen communicating at the proximal end with a side port disposed in a lateral surface of the outer tube and at a distal end communicating with the working lumen of the inner tube to define a bifurcation, the auxiliary lumen being configured to permit the selective advancement of a wire to a treatment site via a distal portion of the working lumen that is distal to the bifurcation;
- and
- a stylet having proximal and distal ends and a guiding member coupled to the distal end, the distal end of the stylet being configured to be advanced into a proximal end of the working lumen.
A method for advancing a catheter into a vessel for use in therapeutic or diagnostic applications, the method comprising:
- providing apparatus comprising an outer tube having proximal and distal ends, an inner tube having proximal and distal ends and a working lumen extending therethrough, wherein the inner tube is disposed within the outer tube, and an auxiliary tube having proximal and distal ends, and an auxiliary lumen extending therethrough, the auxiliary lumen communicating at a proximal end with a side port disposed in a lateral surface of the outer tube and at a distal end communicating with the working lumen of the inner tube to define a bifurcation;
- positioning a wire within the vessel;
- inserting a proximal end of the wire through the distal end of the working lumen;
- and
- causing the proximal end of the wire to be directed into the auxiliary lumen using a stylet.
