Abstract
An elongated thermal energy delivery device for use in endovenous thermal treatment of blood vessel is provided. The energy device includes a flexible guide tip attached to its distal portion which provides for direct tracking and advancement of the energy device through the vein without the use of a treatment sheath. Also provided is a method of using the thermal energy delivery device with flexible guide tip. The method eliminates the need for a treatment sheath and accessory procedural components and the procedural steps associated with these components.
Claims34
An endovascular thermal treatment device comprising:
- an elongated thermal energy delivery device having at its distal portion an energy emitting section;
- and
- a flexible guide tip attached to the distal portion of the energy delivery device and extending distally therefrom, the flexible guide tip adapted to guide the energy emitting section through a blood vessel.
An endovascular thermal treatment device comprising:
- an elongated optical fiber having at its distal end an energy emitting face for emitting laser energy;
- a flexible guide tip attached to a distal portion of the optical fiber and adapted to guide the energy emitting face through a blood vessel, the guide tip extending distally from the distal portion of the optical fiber.
An endovascular treatment method for causing closure or reducing the diameter of a blood vessel comprising:
- advancing through a blood vessel an elongated thermal energy delivery device having at its distal portion an energy emitting section, the distal portion being attached to a flexible guide tip that extends distally from the distal portion;
- applying thermal energy through the energy emitting section while longitudinally moving the advanced energy delivery device.
A method of placing a thermal energy delivery device in a blood vessel comprising:
- creating an access site of a blood vessel;
- and
- through the access site, inserting an elongated thermal energy delivery device into the blood vessel without the use of a treatment sheath, the elongated thermal energy delivery device having at its distal portion an energy emitting section, the distal portion being attached to a flexible guide tip that extends distally from the distal portion.
