Abstract
A catheter device for treating a vascular disease is provided. The catheter device includes an energy delivery device such as an optical fiber for delivering laser energy and a catheter. The catheter lumen receives the optical fiber and a fluid such as an anesthetic agent or vasoconstricting agent. According to the invention, a plurality of exits are formed in the sidewall of the catheter. The exits are in communication with the catheter lumen and administer the fluid into the blood vessel. By administering the fluid from within the catheter lumen, the present catheter device eliminates the need to make numerous external punctures to deliver fluid injections.
Claims26
A catheter device for treating a vascular disease comprising:
- an energy delivery device;
- and
- a catheter operable to be inserted into a blood vessel and including:
- at least one lumen through which the energy delivery device and fluid are received;
- and
- a plurality of exits disposed in the sidewall of the catheter and being in communication with the at least one lumen for administration of the fluid into the blood vessel.
A catheter device with a laser energy delivery device for treating a venous disease, comprising:
- an optical fiber capable of delivering laser thermal energy to a target area to be treated;
- and
- a catheter operable to be inserted into a vein and including:
- at least one lumen through which the optical fiber and fluid are received;
- and
- a plurality of exits disposed in the sidewall of the catheter and being in communication with the at least one lumen for administration of the fluid into the vein.
A catheter device with a laser energy delivery device for treating varicose veins, comprising:
- an optical fiber capable of delivering thermal laser energy to a target area to be treated;
- and
- a catheter operable to be inserted into a varicose vein and including:
- at least one lumen through which the optical fiber and a fluid are received, the fluid containing a vasoconstricting agent or anesthetic agent, or both;
- and
- a plurality of exits disposed in the sidewall of the catheter and being in communication with the at least one lumen for administration of the fluid into the varicose vein.
A method of treating a vascular disease comprising:
- inserting into a vessel a catheter having at least one lumen and a plurality of exits disposed in the sidewall of the catheter;
- inserting an energy delivery device into the at least one lumen of the catheter to position a distal end of the energy delivery device near a distal end of the catheter;
- and
- introducing a fluid into the at least one lumen of the catheter such that the fluid flows out of the at least one lumen into the vessel through the plurality of exits in the sidewall.
