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-modified1 - 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.Cited by (0)
