A method for producing hemostasis of an artery of a patient having a puncture following arterial catheterization including introducing a hemostasis device including at least one electrode into the vicinity of the puncture, supplying an electric current to the at least one electrode, thereby heating
A method for producing hemostasis of an artery of a patient having a puncture following arterial catheterization including introducing a hemostasis device including at least one electrode into the vicinity of the puncture, supplying an electric current to the at least one electrode, thereby heating blood in the vicinity of the puncture and causing coagulation of the blood and subsequently removing the hemostasis device from the patient.
1. A method for producing hemostasis of an artery of a patient having a puncture following arterial catheterization comprising: introducing a hemostasis device into a vicinity of the puncture, the hemostasis device comprising: a main shaft;an expandable member disposed on the main shaft; andat least
1. A method for producing hemostasis of an artery of a patient having a puncture following arterial catheterization comprising: introducing a hemostasis device into a vicinity of the puncture, the hemostasis device comprising: a main shaft;an expandable member disposed on the main shaft; andat least one electrode coupled to the main shaft;expanding the expandable member to form a region delimited by engagement of the expandable member against an outside of an artery wall;allowing a limited volume of blood to collect outside the artery wall and within the region;supplying an electric current to said at least one electrode, thereby heating the region causing coagulation of the limited volume of blood in the region and causing closure of said puncture; andsubsequently removing said hemostasis device from the patient. 2. A method according to claim 1 and wherein said at least one electrode comprises a pair of electrodes. 3. A method according to claim 1 and wherein said introducing comprises introducing via a catheter introducer. 4. A method according to claim 1 and wherein said introducing also comprises inflating an anchor balloon attached to an end of said hemostasis device. 5. A method according to claim 4, further comprising deflating the anchor balloon. 6. A method according to claim 1 and wherein said removing of said hemostasis device comprises deflating said expandable member. 7. A method according to claim 1 and wherein said introducing also comprises positioning said at least one electrode in close proximity to the region. 8. A method according to claim 1 and wherein said supplying comprises supplying electrical power at RF frequencies. 9. A method according to claim 8 and wherein said electrical power comprises electrical power in the range of 0.1-10 watts at up to 25 volts. 10. A method according to claim 1 and wherein said supplying also comprises adjusting said electric current based on feedback measurement. 11. A method for producing hemostasis of an artery of a patient having a puncture following arterial catheterization comprising: introducing a hemostasis device into a vicinity of the puncture, the hemostasis device comprising: a main shaft;an expandable member disposed on the main shaft; andat least one electrode coupled to the main shaft;positioning said at least one electrode in proximity with said puncture;expanding the expandable member to form a region delimited by engagement of the expandable member against an outside of an artery wall;allowing a limited volume of blood to collect outside the artery wall and within the region;supplying an electric current to said at least one electrode, thereby heating the region, causing coagulation of the limited volume of blood in the region and causing closure of said puncture; andsubsequently removing said hemostasis device from the patient. 12. A method according to claim 11 and wherein said positioning comprises: inflating an anchor balloon attached to an end of said hemostasis device;and subsequently deflating said anchor balloon. 13. A method according to claim 11 and wherein said at least one electrode comprises a pair of electrodes. 14. A method according to claim 11 and wherein said supplying comprises supplying electrical power at RF frequencies. 15. A method according to claim 14 and wherein said electrical power comprises electrical power in the range of 0.1-10 watts at up to 25 volts. 16. A method according to claim 11 and wherein said supplying also comprises adjusting said electric current based on a feedback measurement.
