Method and system for circumcision

Abstract

A system for effecting ischemic necrosis in a foreskin of a penis includes an inner ring having an inner surface comprising an inner diameter and an outer surface comprising an outer diameter and at least one circumferential groove; and an outer ring configured to substantially fit around the circumferential groove of the inner ring, wherein the inner ring is configured to fit to a portion of a glans of the penis that lies between an inner surface of the foreskin and the glans of the penis and the at least one outer ring is configured to fit an outer surface of the foreskin, the inner ring and the outer ring thereby compressing the foreskin in the circumferential groove with a compression force, and wherein the compression force is sufficient to effect ischemic necrosis in the foreskin.

What is claimed is: 
     
         1 . A method for circumcising a foreskin of a penis, comprising:
 positioning at least one inner ring over a portion of a glans of the penis that lies between an inner surface of the foreskin and the glans of the penis;   positioning at least one outer ring around an outer surface of the foreskin, thereby applying a compression force over the foreskin between the inner ring and the outer ring, the compression force being sufficient to effect ischemic necrosis of the foreskin; and   removing necrotic foreskin.   
     
     
         2 . The method of  claim 1 , comprising positing the outer ring directly over the outer surface of the foreskin. 
     
     
         3 . The method of  claim 1 , comprising using a deployment element for positing the outer ring over the outer surface of the foreskin. 
     
     
         4 . The method according to  claim 1 , wherein the compression force is substantially between a pressure range of 0.1-20 atmospheres. 
     
     
         5 . The method according to  claim 1 , comprising retracting the foreskin sufficiently to reveal at least a portion of the glans of the penis before positioning the inner ring around the portion of the glans of the penis. 
     
     
         6 . The method according to  claim 1 , comprising pulling retracted foreskin over the inner ring after the positioning of the inner ring around the portion of the glans of the penis. 
     
     
         7 . The method according to  claim 1 , comprising stretching an opening of the foreskin sufficiently to insert inner ring through the opening before positioning the inner ring around the portion of the glans of the penis. 
     
     
         8 . The method according to  claim 1 , comprising vertically positioning the inner ring through the opening. 
     
     
         9 . The method of  claim 1 , wherein the inner ring is a rigid or semi rigid ring element comprising an inner surface comprising an inner diameter; and an outer surface comprising an outer diameter and at least one circumferential groove and the outer ring is elastic and is positioned to substantially fit around the circumferential groove of the rigid or semi rigid ring. 
     
     
         10 . A system for effecting ischemic necrosis in a foreskin of a penis, comprising
 an inner ring comprising an inner surface comprising an inner diameter and an outer surface comprising an outer diameter and at least one circumferential groove; and   an outer ring being configured to substantially fit around the circumferential groove of the inner ring,   wherein the inner ring is configured to fit to a portion of a glans of the penis that lies between an inner surface of the foreskin and the glans of the penis and the at least one outer ring is configured to fit an outer surface of the foreskin.   
     
     
         11 . The system of  claim 10 , wherein the inner diameter of the inner ring in a relaxed state is at least slightly larger than a diameter of a shaft of the penis; wherein a diameter of the at least one outer ring in a relaxed state is at least substantially equal to the diameter of the shaft of the penis. 
     
     
         12 . The system of  claim 10 , wherein the outer ring is fitted around the circumferential groove to apply a compression force, the compression force being substantially between a pressure range of 0.1-20 atmospheres. 
     
     
         13 . The system of  claim 10 , wherein the at least one circumferential groove has an asymmetrical cross sectional shape. 
     
     
         14 . The system of  claim 10 , wherein a radial direction of the at least one circumferential groove is perpendicular to a longitudinal axis of at least one of the inner ring and the outer ring. 
     
     
         15 . The system of  claim 10 , comprising a deployment element configured to hold the at least one outer ring in a stretched form and for releasing the at least one outer ring over a portion of the foreskin and for fitting into the at least one circumferential groove of the inner ring, once the inner ring is placed around a portion of the penis. 
     
     
         16 . The system of  claim 15 , wherein the deployment element comprises at least three flanges, each one of the at least three flanges substantially located around a circumference of the deployment element, such that the outer ring is stretched around the at least three flanges, in a polygon shape. 
     
     
         17 . The system of  claim 10 , wherein the inner ring is a rigid or semi rigid ring and the outer ring is elastic. 
     
     
         18 . A system for effecting ischemic necrosis in a foreskin of a penis, comprising:
 a rigid or semi-rigid ring, the rigid or semi-rigid ring comprising an inner surface comprising an inner diameter; and an outer surface comprising an outer diameter and at least one circumferential groove;   at least one elastic ring being configured to substantially fit around the circumferential groove of the rigid or semi rigid ring; and   a deployment ring configured to hold the at least one elastic ring in a stretched form and for releasing the at least one elastic ring over a portion of the foreskin and for fitting into the at least one circumferential groove of the rigid ring, once the rigid ring is placed around a portion of the penis.   
     
     
         19 . The system of  claim 18 , wherein the elastic ring is fitted around the circumferential groove to apply a compression force, the compression force being substantially between a pressure range of 0.1-20 atmospheres. 
     
     
         20 . The system of  claim 18 , wherein the inner diameter of the rigid or semi-rigid ring in a relaxed state is at least slightly larger than a diameter of a shaft of the penis; wherein a diameter of the at least one elastic ring in a relaxed state is at least substantially equal to the diameter of the shaft of the penis; and wherein the rigid or semi-rigid ring is placed around a first surface of the foreskin.
