Abstract

A method for treating a varicose vein comprises heating a dehiscent portion of a wall of the vein so as to produce a localized retraction of collagen. Heating may be via application of high-intensity focused ultrasound energy.

Claims

exact text as granted — not AI-modified
1 - 22 . (canceled) 
     
     
         23 . A method for treating a varicose vein, comprising heating a dehiscent portion of a wall of said vein so as to produce a localized retraction of collagen over a length of said vein. 
     
     
         24 . A method according to  claim 23 , wherein said heating is obtained by application of high-intensity focussed ultrasound (HIFU) energy. 
     
     
         25 . A method according to  claim 24 , wherein said heating is produced at the level of an insertion ring for a valve so as to close the valve and suppress the blood reflux. 
     
     
         26 . A method of  claim 23 , wherein said heating is produced at the level of an insertion ring for a valve so as to close the valve and suppress the blood reflux. 
     
     
         27 . A method according to  claim 23 , wherein said treating is controlled by Doppler ultrasonography using an imaging transducer. 
     
     
         28 . A method according to  claim 27 , wherein said imaging transducer is oriented so as to image a section of said vein. 
     
     
         29 . A method according to  claim 27 , wherein said imaging transducer is oriented so as to allow monitoring by the Doppler ultrasonography of blood flow in said vein. 
     
     
         30 . A method according to  claim 23 , wherein said treating is monitored by elastography.
