Patent ID: 8864812

Claim:
An interventional delivery system for simultaneously delivering a plurality of vessel devices to an acutely angled branched treatment site, said interventional delivery system comprising: a first catheter having a catheter shaft with a proximal end and a distal end; a side branch vessel segment separate from the first catheter; a connection fixedly securing the catheter shaft and the side branch vessel segment such that the side branch vessel segment extends from the distal end generally toward the proximal end of the catheter shaft and an apex opening is defined between the catheter shaft and the side branch vessel segment; a second catheter having a main body with a proximal end and a distal end, the main body being disposed around at least a portion of the first catheter a side branch vessel device attached to the side branch vessel segment of the first catheter; a main vessel device attached to the distal end of the second catheter main body; and a bifurcated guidewire having a main segment extending through the catheter shaft and terminating at a connection point, the bifurcated guidewire having a leading tip and a reverse facing tip each extending from the connection point, the leading and reverse facing tips extending in generally opposite directions, wherein the leading tip extends through the apex opening and the reverse facing tip extends into the side branch vessel segment, the reverse facing tip being axially slidable within the side branch vessel segment in response to selective axial displacement of the main segment of the bifurcated guidewire relative to the catheter shaft.
