Abstract
A blood vessel occlusion system and method includes a handheld probe including a power source, the probe being adapted to transmit energy from the power source through a body surface and into a target blood vessel, for example a varicose vein. Further included is a manual or automatic switch mechanism adapted to enable and disable the power source in response to a predetermined level of compression applied, by means of the probe against the target blood vessel. When the blood vessel is compressed sufficiently to collapse and substantially slow or substantially prevent a flow of blood therethrough, the power source is activated and the vessel is cauterized, leaving the blood vessel in a condition that is resistant to recanalization.
Claims9
A method for occluding a target blood vessel such as a varicose vein, the method comprising the steps of:
- applying sufficient pressure to the target blood vessel to cause collapse of the vessel and substantially slow a flow of blood therethrough,
- trapping at least some of the blood in a compressed portion of the blood vessel;
- and
- transmitting energy into the target blood vessel, during the step of applying sufficient pressure, to permanently close the vessel.
