Guiding catheter stabilization system

摘要

Guiding catheter support devices, systems, and methods for stabilizing a guiding catheter while positioned in a vessel of a patient are disclosed. The device comprises a stabilizing wire with an elongate portion and a fortified end, wherein the fortified end is more rigid than the elongate portion. The stabilizing wire is inserted into a guiding catheter while it is positioned in a vessel of a patient and increases the rigidity of at least a portion of the guiding catheter thereby providing support and stabilizing the catheter. A standard guiding catheter may be used or a guiding catheter with a primary lumen and a stabilization lumen having a blind distal end may be used, wherein the stabilizing wire is inserted into the stabilization lumen.

主权项

1. A guiding catheter system, comprising:
a guiding catheter comprising a proximal end, a distal end, a primary lumen and a secondary lumen; and a stabilizing wire comprising an elongate part and a first fortified end disposed on a first end of the elongate part, wherein the first fortified end forms a first end of the stabilizing wire and is more rigid than the elongate part; wherein the secondary lumen extends the entire length of the guiding catheter and has a distal blind end at a distal edge of the distal end of the guiding catheter; and wherein the stabilizing wire is configured to be inserted into the secondary lumen to the blind end while the guiding catheter is at an ostium of a vessel of a patient such that the first fortified end of the stabilizing wire increases the rigidity of at least a portion of the guiding catheter thereby preventing the guiding catheter from disengaging from the ostium of the vessel; and wherein the first fortified end of the stabilizing wire is configured to change the shape of at least a portion of the guiding catheter when the first fortified end of the stabilizing wire is inserted such that the guiding catheter rests on a wall of the aorta opposite an ostium of a coronary artery.
