Abstract
A method and device for improved minimally invasive vascular treatments. The method comprises introducing a catheter into a vein to be treated. The catheter is adapted to introduce an energy transmitting member and a fluid into the vein to be treated. The fluid introduced via the catheter can include, but is not limited to: saline solutions, cooled saline solutions, liquids for vapor generation, vasoconstricting agents, anesthetic agents and/or a formulation containing an ingredient which can be activated by the applied energy.
Claims27
A method of treating veins, comprising:
- introducing a treatment device inside a vein;
- providing a cooling fluid directly inside the vein via a distal end of the treatment device to internally cool the vein;
- introducing an energy-transmitting member inside the vein via the distal end of the treatment device to irradiate the vein with energy;
- advancing a distal end of the energy-transmitting member to protrude beyond the distal end of the treatment device inside the vein;
- and
- irradiating said vein via the protruding distal end of the energy-transmitting member;
- and
- wherein a part of said cooling fluid is vaporized during the step of irradiating said vein.
An endoluminar method of treating vascular irregularities, comprising:
- providing a multichannel introducing device inside a vein;
- delivering a fluid via the multichannel introducing device to directly infuse a treatment site inside the vein with the fluid;
- introducing an energy-transmitting member to the treatment site inside the vein via a distal end of the multichannel introducing device;
- advancing a distal end of the energy-transmitting member to protrude beyond the distal end of the multichannel introducing device inside the vein;
- and
- irradiating the treatment site inside the vein via the protruding distal end of the energy-transmitting member;
- wherein the treatment site inside the vein is infused with the fluid prior to or simultaneously with energy emission from the protruding distal end of said energy-transmitting member.
A device for treating veins, comprising:
- an energy-transmitting member adapted to emit energy to a vein from inside the vein;
- and
- a catheter configured to be positioned inside the vein;
- wherein the catheter is adapted to introduce a cooling fluid directly inside the vein and to introduce the energy-emitting member inside the vein;
- wherein a distal end of the energy-transmitting member is configured to protrude beyond a distal end of the catheter to irradiate the inside of the vein;
- and
- wherein a part of said cooling fluid is vaporized during irradiation of said vein.
A treatment system for endoluminar treatment of vascular irregularities comprising:
- an energy-transmitting member adapted to emit energy to a vein from inside the vein;
- and
- a catheter configured to be positioned inside the vein;
- wherein a distal end of the catheter is adapted to introduce a cooling fluid directly inside the vein and to introduce the energy-transmitting member inside the vein, such that at least some of the cooling fluid is vaporized inside the vein by the energy emitted by the energy-transmitting member;
- and
- wherein a distal end of the energy-transmitting member is configured to protrude beyond the distal end of the catheter to irradiate the inside of the vein.
A treatment system for endoluminar treatment of vascular irregularities comprising:
- an energy-transmitting member adapted to emit energy to a vein from inside the vein;
- and
- a catheter configured to be positioned inside the vein;
- wherein the catheter comprises at least one channel for introducing the energy-transmitting member inside the vein and at least one channel for introducing a cooling fluid directly inside the vein and wherein a part of said cooling fluid is vaporized during irradiation of said vein;
- and
- means for timing said introduction of the cooling fluid and for timing energy emission from said energy-emitting member;
- wherein a distal end of the energy-transmitting member is configured to protrude beyond a distal end of the catheter to irradiate the inside of the vein.
