摘要:
A method includes inserting into a patient body acatheter, which includes an insertion tube and at leastan expandable distal-end device coupled to a distal endof the insertion tube. The distal-end device is expandedin a blood vessel, thereby forming an annular guidingtrench between the distal-end device and a circumferenceof the blood vessel, the annular trench shaped to receiveand guide a distal tip of a medical instrument. Thedistal tip of the medical instrument is guided in theannular guiding trench formed by the expanded distal-enddevice of the catheter, so as to approach multiple pointson the circumference of the blood vessel.
