Abstract
The methods of the invention include examining a blood vessel to be treated, preferably with the aid of ultrasound, calculating a volume of the portion of the blood vessel, and treating the portion with a volume of treatment agent where the volume of treatment agent is a function of the volume of the portion of the blood vessel. Apparatus for implementing the methods are provided.
Claims26
A method for determining a treatment volume of a fluid treatment agent for treating the interior of a portion of a blood vessel, said method comprising:
- obtaining an indication of a volume V of the portion of the blood vessel to be treated;
- and
- determining said treatment volume as a function of said indication.
A method for treating a portion of a blood vessel with a sclerosing agent, comprising:
- determining indications of diameters of the blood vessel at a plurality of locations along said blood vessel;
- using said indications, determining a sclerosing agent treatment volume;
- and
- using said sclerosing agent treatment volume to treat said portion of said blood vessel.
A method according to 18, wherein:
- said function is a fraction of said blood vessel volume V minus a volume.
An apparatus for calculating the treatment volume of a treatment agent to be dispensed inside a blood vessel for treating a portion of the blood vessel, comprising:
- input means for receiving data related to the length of said portion of the blood vessel and diameters at least three locations along the length of said portion of the blood vessel;
- processor means for calculating the volume of the blood vessel based on said data and for calculating the treatment volume based on the volume of the blood vessel;
- and
- output means for conveying the treatment volume, said output means being coupled to the processor means.
