Gentle hemorrhoid treatment offering a substantially painless healing
The teachings provided herein are directed to a methods and devices for treating a hemorrhoid in a subject in a manner that produces substantially less post-procedural pain in the subject, the method minimizing or avoiding a removing or a necrosis of a rectal tissue fold.
1. A method of treating a hemorrhoid comprising:
inserting an anoscope including a body defining a proximal opening into an anus of a subject having a hemorrhoid, the body defining a work space communicating with the proximal opening;
directly visualizing the rectal tissue through the anoscope;
forming a fold of rectal tissue through a window defined in the anoscope above the hemorrhoid and a dentate line in the subject, the fold of rectal tissue including a vascular supply to the hemorrhoid;
securing the fold of rectal tissue with a pressure in a range of 10 kPa to 1000 kPa between pinching surfaces of the anoscope; and
occluding the vascular supply to the hemorrhoid in a targeted manner by delivering energy to the pinching surfaces of the anoscope to heat the fold of rectal tissue to a temperature in a range of 50° C. to 65° C. and to avoid removal of or necrosis of rectal tissue to facilitate ischemic regression of the hemorrhoid.
2. The method of claim 1 , further including limiting the time period for securing the fold of rectal tissue to avoid removal or necrosis of the rectal tissue.
3. The method of claim 1 , further comprising incorporating a portion of the hemorrhoid into the fold.
4. The method of claim 1 , wherein securing the fold includes securing the fold with a pressure in the range of 50 kPa to 1000 kPa.
5. The method of claim 1 , wherein heating the fold of rectal tissue includes applying the energy from a plurality of discrete regions on the pinching surfaces of the anoscope to a corresponding plurality of discrete areas on the fold of rectal tissue.
6. The method of claim 1 , wherein securing the fold of rectal tissue includes applying pressure to the fold of rectal tissue at an angle ranging from about 0 degrees to about 90 degrees from a central axis of the anoscope.
7. The method of claim 1 , wherein occluding the vascular supply to the hemorrhoid in a targeted manner includes providing RF energy to the fold of rectal tissue.
8. The method of claim 1 , wherein securing the fold of rectal tissue includes actuating a handle of the anoscope to move a shutter of the anoscope to compress the fold of rectal tissue between the pinching surfaces of the anoscope.
9. The method of claim 1 , wherein directly visualizing rectal tissue through the anoscope includes visualizing the rectal tissue through the proximal opening.
10. The method of claim 1 , wherein directly visualizing rectal tissue through the anoscope includes visualizing the rectal tissue without using fiber optics.
11. A method of facilitating ischemic regression of a hemorrhoid comprising:
inserting an anoscope including a body defining a proximal opening into an anus of a patient having a hemorrhoid, the body defining a work space communicating with the proximal opening;
directly visualizing rectal tissue through the anoscope;
identifying rectal tissue that has a vascular supply to the hemorrhoid;
forming a fold of rectal tissue through a window defined in the body above the hemorrhoid and a dentate line;
securing the fold of rectal tissue between pinching surfaces of the anoscope; and
subsequently occluding the vascular supply to the hemorrhoid without removing or causing necrosis of the rectal tissue within the fold of rectal tissue to achieve ischemic regression of the hemorrhoid, wherein occluding the vascular supply to the hemorrhoid includes heating the fold of rectal tissue to a temperature within a range of 50° C. to 65° C. through application of energy through the pinching surfaces of the anoscope.
12. The method of claim 11 , further including limiting the time period for securing the fold of rectal tissue to avoid removal or necrosis of the rectal tissue.
13. The method of claim 11 , wherein forming a fold of rectal tissue includes positioning the rectal tissue between the pinching surfaces of the anoscope.
14. The method of claim 13 , wherein heating the fold of rectal tissue includes applying an energy from a plurality of discrete regions on the pinching surfaces of the anoscope to a corresponding plurality of discrete areas on the fold of rectal tissue.
15. The method of claim 11 , wherein securing the fold of rectal tissue includes applying pressure to the fold of rectal tissue at an angle ranging from about 0 degrees to about 90 degrees from a central axis of the anoscope.
16. The method of claim 11 , wherein heating the fold of rectal tissue to a temperature within a range of 50° C. to 65° C. includes providing RF energy to the fold of rectal tissue.
17. The method of claim 11 , further including facilitating visualization of the fold of rectal tissue by forming the anoscope at partially from a translucent or transparent material.
18. The method of claim 11 , wherein directly visualizing rectal tissue through the anoscope includes visualizing the rectal tissue through the proximal opening.
19. The method of claim 11 , wherein directly visualizing rectal tissue through the anoscope includes visualizing the rectal tissue without using fiber optics.
