1. A guiding device for inserting and advancing more than one catheter and/or guidewire through a vascular tree of a patient in an endovascular treatment, the device comprising:
- a shaft comprising a proximal end, a distal end and at least one fluid delivery lumen in fluid communication with the proximal end and the distal end, the distal end including a wire-guiding channel having a length for slidably receiving a guiding wire whereby the shaft may be advanced through a blood vessel of the patient by slidably advancing the distal end of the shaft over the guiding wire, wherein the guiding channel comprises a resilient groove open to one side of the guiding channel and adapted for lateral insertion and resilient retention of the guiding wire in the guiding channel.

Abstract
A guiding device and method for inserting and advancing more than one catheter and/or guidewire through the vascular tree of a patient in endovascular treatments, particularly through tortuous blood vessels, the guiding device comprising an open or close guiding channel provided at a distal end of the catheter or guidewire, whereby the catheter or guidewire may be easily advanced through the vessel over a previously installed guidewire.

9. A guiding device for inserting and advancing more than one guidewire through a vascular tree of a patient in an endovascular treatment, the device comprising:
- a flexible conduit defining a main guidewire comprising a proximal end, a distal end, and at least one lumen in fluid communication with the proximal end and the distal end, the distal end including a guiding channel having a length for slidably receiving an additional guidewire whereby the main guidewire may be advanced through a blood vessel of the patient by slidably advancing the distal end over the additional guidewire, wherein the guiding channel comprises a resilient groove open to one side of the guiding channel and adapted for lateral insertion and resilient retention of the guiding wire in the guiding channel.

16. A method for inserting and advancing more than one catheter and/or guidewire through a vascular system of a patient in an endovascular treatment, the method comprising the steps of:
-
providing a catheter having a catheter shaft comprising a proximal end, a distal end and at least one fluid delivery lumen in fluid communication with the proximal end and the distal end, the distal end including a guiding channel having a length for slidably receiving a guiding wire, wherein the guiding channel comprises a resilient groove, laterally inserting the guiding wire into the channel of the catheter through the resilient groove, and advancing the catheter through a vessel of the patient by slidably advancing the distal end over the guiding wire. - View Dependent Claims (17, 18)
