Method, system, and apparatus for dermatological treatment
An apparatus for treating dermatological tissue, including at least two pins configured to be inserted in dermatological tissue to deliver electromagnetic energy to target dermatological tissue, and an electrical signal generator electrically coupled to the at least two pins, and creating a pulsed electrical signal across the at least two pins.
1. A method for treating a blood vessel in dermatological tissue, comprising:
inserting at least two pins in the dermatological tissue so as to cause the blood vessel in dermatological tissue to be positioned between the at least two pins; and
applying a repetitive pulsed electrical signal across the at least two pins to deliver electromagnetic energy to target the blood vessel,
wherein the repetitive pulsed electrical signal has a plurality of pulses, each pulse having a duration, with consecutive pulses separated by a delay time,
wherein the pulse duration is in a range of 10 to 300 msec, and the delay time is in a range of 5 to 100 msec.
2. The method of claim 1 , wherein the duration of the delay time limits undesired thermal injury to the dermatological tissue surrounding the blood vessel caused by sustained delivery of electrical energy.
3. The method of claim 1 , wherein the at least two pins form a bipolar configuration.
4. An apparatus for treating dermatological tissue, comprising:
at least two pins configured to be inserted in the dermatological tissue and positioned to have a blood vessel in dermatological tissue therebetween; and
an electrical signal generator electrically coupled to the at least two pins, and configured to create a repetitive pulsed electrical signal across the at least two pins to deliver electromagnetic energy to target the blood vessel,
wherein the repetitive pulsed electrical signal has a plurality of pulses, each pulse having a duration, with consecutive pulses separated by a delay time,
wherein the pulse duration is in a range of 10 to 300 msec, and the delay time is in a range of 5 to 100 msec.
5. The apparatus of claim 4 , wherein the at least two pins form a bipolar configuration.
6. The apparatus of claim 4 , wherein each pulse has a root mean square voltage level between 20 V and 250 V for a duration of 10 msec to 300 msec.
