Abstract
A process for heat treating biological tissue includes providing a plurality of energy emitters formed into an array. Treatment energy is generated from the plurality of emitters and applied to target tissue. The treatment energy has energy and application parameters selected so as to raise the target tissue temperature sufficiently to create a therapeutic effect while maintaining an average temperature of the target tissue over several minutes at or below a predetermined temperature so as not to destroy or permanently damage the target tissue.
Claims26
A process for heat treating biological tissue, comprising the steps of:
- providing a plurality of energy emitters formed into an array;
- generating treatment energy from the plurality of emitters;
- providing an initial treatment to target tissue by repeatedly applying the energy to the target tissue in a pulsed manner for the exposure duration comprising less than one second;
- halting application of the pulsed energy to the target tissue for an interval of time comprising between three seconds and three minutes;
- and
- providing a secondary treatment to the target tissue after the interval of time, within a single treatment session, by repeatedly reapplying the pulsed energy for the exposure duration comprising less than one second
- wherein the treatment energy has energy and application parameters selected so as to raise the target tissue temperature sufficiently to create a therapeutic effect while maintaining an average temperature of the target tissue over several minutes at or below a predetermined temperature so as to not destroy or permanently damage the target tissue.

- and
- wherein during an interval of time, comprising less than one second, between applications of energy applied to a first area of the target tissue, applying treatment energy to a second area of the target tissue sufficiently spaced apart from the first area of the target tissue to avoid thermal tissue damage of the target tissue;
- and
- including the step of introducing a phase delay in the activation of the energy emitters of the array to generate treatment energy in a phased manner using a predetermined delay of activation in order to apply treatment energy to each of the first and second areas of the target tissue.
