摘要:
A catheter having a distal assembly with multiple spines with proximal endsaffixed to thecatheter and free distal ends. The spines have different lengths so distalends of the spines tracedifferent circumferences along an inner tissue surface of a tubular region tominimize risk of veinstenosis. The spine lengths can be configured so that the distal ends trace ahelical pattern. Thedistal assembly may have a plunger which deflects the spines when movedlongitudinallyrelative to the distal assembly. The catheter may include a second distalassembly distal of a firstdistal assembly wherein the first and second distal assemblies are separatedby a fixed distancedor an adjustable distance.
