20140214071 | EMBOLIC COIL DELIVERY SYSTEM AND METHOD OF USING SAME - A device and method of treating an aneurysm in a cranial artery of a patient includes providing a coil delivery system having a bypass catheter with a proximal end portion, a distal end portion, and an intermediate portion. The bypass catheter also includes a bypass lumen extending from the proximal end portion to the distal end portion and a coil delivery lumen that extends from the proximal end portion to a coil delivery opening in a side wall of the bypass catheter. The coil delivery system also includes an embolic coil or multiple coils capable of being deployed separately through the coil delivery opening and electrolytically detached, and at least one balloon disposed about an outer surface of the bypass catheter and capable of substantially preventing blood flow around the outer surface of the bypass catheter when inflated. The system may be used without coil embolization to provide endovascular bypass with segmental vessel occlusion during brain surgery such as craniotomy with clipping of a cerebral aneurysm. | 07-31-2014 |
20120004596 | Catheter for Use in Revascularization Procedures and Method of Using Same - A method of removing vascular blockage includes providing a catheter system. comprising an outer catheter, a cutting catheter having a serrated distal end, a bypass catheter, and a guidewire. In the catheter system, the bypass catheter is slidably disposed within the cutting catheter and the outer catheter. The method includes positioning a distal end of the catheter system at a proximal end of an occlusion located within a vessel and moving the bypass catheter through the occlusion so that a medicated treatment solution may be delivered through the bypass catheter to an area of the brain or other tissue served by the vessel blocked by the occlusion. Both during and after the delivery of medicated treatment solution to the blocked part of the vessel with the bypass catheter, the physician may engage the occlusion with the cutting catheter by moving the cutting catheter in a clockwise/counterclockwise or forward/backward direction within the outer catheter, cutting and then removing at least a portion of the occlusion from the vessel. | 01-05-2012 |
