Abstract
The invention relates to an RF-activated guidewire to electrosurgically pass through occlusive material to allow the use of other vescular therapeutic devices to traverse the guidewire through the occlusive material. More particularly, the invention relates to a catheter system for penetrating occulsive tissue in an arterial lumen, comprising: a substantially tubular sheath means; an electrically conductive guidewire, said guidewire having an electrosurgical tip and passing through said sheath means; and a voltage generating means electrically connected to said electrically conductive guidewire to activate said electrosurgical tip.
