Patent Images
1. A hemostasis device for closing a puncture in an artery wall, comprising:
- a main shaft;
at least one expandable member disposed on the main shaft, wherein the expandable member in one configuration is adapted to delimit a blood coagulation volume by the engagement of the expandable member against an outside of an artery wall; and
at least one electrode, operable to supply an electric current, coupled to the main shaft in the vicinity of the blood coagulation volume, wherein upon activation of the electrode, the electrode is adapted to cause blood disposed in the blood coagulation volume to coagulate thereby causing a closure of the puncture.
