Energy induced bulking and buttressing of tissue for incontinence
View Patent ↗Devices, systems, and method for treating urinary incontinence generally rely on energy delivered to a patient's own pelvic support tissue to selectively contract or shrink at least a portion of that pelvic support tissue so as to reposition the bladder. Devices and methods apply gentle resistive heating of tissues to cause them to contract without imposing significant injury on the surrounding tissue structures. Alternative heat-applying probes heat tissue structures which comprise or support a patient's urethra. By selectively contracting the support tissues, the bladder neck, sphincter, and other components of the urinary tract responsible for the control of urinary flow can be reconfigured or supported in a manner which reduces urinary leakage.
1. A method for inhibiting incontinence of a patient, the method comprising:
advancing an electrode of aprobe into a collagenous target tissue, the electrode comprising a needle electrode; and
transmitting energy from an energy-directing element of the probe to the collagenous target tissue, the collagenous target tissue comprising or supporting a urethra of the patient, the energy being transmitted so as to induce a healing response in the collagenous target tissue, the healing response comprising bulking or buttressing of the collagenous target tissue and the bulking or buttressing of the collagenous target tissue inhibiting the incontinence, wherein the energy comprises RF energy delivered with the electrode of the probe.
2. The method of claim 1 , wherein the energy heats the collagenous target tissue sufficiently to induce shrinkage of the collagenous target tissue.
3. The method of claim 1 , further comprising introducing the probe transvaginally.
4. The method of claim 1 , wherein the tissue comprises fascia.
5. A method for inhibiting incontinence of a patient, the method comprising:
introducing a probe into a body of the patient;
penetrating into one or more tissues of the body with a plurality of tips of the probe; and
transmitting energy from the probe into the one or more tissues of the body to heat the tissue so that healing of the tissue results in bulking and buttressing of the tissue, and so that the healing-induced bulking and buttressing of the tissue inhibits incontinence.
6. The method of claim 5 , further comprising inserting the probe into a urethra of the patient.
7. The method of claim 5 , further comprising using a finger inserted into the patient to position the probe.
8. The method of claim 5 , wherein the tissue is heated to a temperature in a range from 60 to 110 C.
9. The method of claim 8 , wherein the energy comprises an electrical potential, and further comprising controlling the temperature of the tissue by limiting the electrical potential and limiting energy applied to the tissue with a timer coupled to the electrical potential.
10. A method for inhibiting incontinence of a patient, the method comprising:
introducing a probe into a body of the patient;
advancing an array of sharpened tips from the probe into a bladder neck and applying an electrical potential to the array;
transmitting energy from the probe into the bladder neck of the patient body to heat the bladder neck so that the bladder neck inhibits incontinence.
11. The method of claim 10 , further comprising using a finger inserted into a vagina of the patient to position the probe.
