摘要： A medical apparatus and method useful for the efficacious thermal treatment of lumen such as varicose veins during laser surgery is provided. The method includes inserting an optical fiber into a lumen at a treatment site which has at least two treatment segments. The light-emitting section of the optical fiber is aligned with a first treatment segment within the treatment site. Energy is emitted into the lumen at the first treatment segment and a temperature of the lumen is measured at the first treatment segment. The energy delivered to the treatment segment can be adjusted in response to the temperature measurement. The light-emitting section is moved to at least a second treatment segment within the lumen and energy is emitted into the lumen at the second treatment segment. During treatment at the second treatment segment, the temperature of the lumen is measured at the second treatment segment. This method can also include storing a temperature target in the memory device; generating a temperature signal using the temperature sensor; utilizing the temperature signal to determine the measured temperature; and comparing the measured temperature to the temperature target stored in the memory device. The light-emitting section is moved to the next treatment segment when the measured temperature is equal or greater than the temperature target.

摘要： A medical apparatus and method useful for the efficacious thermal treatment of lumen such as varicose veins during laser surgery is provided. An energy delivery device comprising a diffusing optical fiber with a light-emitting section and a memory device having data programmed therein is also provided. The optical fiber includes a temperature sensor for measuring a temperature at a treatment site. An energy generator is connected to the optical fiber and to a positioning device. The optical fiber engages positioning device so that the positioning device can moveably position the light-emitting section of the optical fiber. Consequently, the optical fiber can be inserted directly into an appropriate position within a varicose portion of a vein or other lumen for thermal treatment of the vein. The memory device and a main processor are used to automatically control the operation of the medical apparatus including the intensity of energy emitted and the movement or position of the light-emitting section of the optical fiber within the vein being treated.

摘要： The present invention provides an energy delivery device for use with a medical treatment system for the more efficacious treatment of patients during laser surgery which limits the number of uses or prevents reuse of the energy delivery device after a certain threshold limit has been reached. The energy delivery device comprises a diffusing optical fiber and a memory device having data programmed therein and being operatively connected to an energy generator the optical fiber includes a temperature sensor for generating a temperature signal in a closed loop manner. The data stored in the memory device includes a multiplicity of use parameters, usage limits, usage counts, and count limits all relating to the properties of the medical treatment system. The use parameters may include an elapsed time, a total treatment time, and a number of treatment sites. A main processor is also included for calculating a temperature from the temperature signal and for updating the use parameters in response to data received by the main processor. The main processor is also used to compare the use parameters to their corresponding usage limits. The main processor can create and increment a usage count when at least one of the use parameters exceeds its corresponding usage limit. Thereafter, the main processor compares the usage count to the count limit and disables the energy delivery device when the usage count exceeds a predetermined count limit.

摘要： A diffusive tip assembly for controlling a light intensity profile during a medical procedure is provided. The diffusive tip assembly includes an optical fiber including a core and a diffuser tip that surrounds a distal end of the core. The diffuser tip includes multiple light directing features that are shaped and arranged in a pattern along an axial length of the diffuser tip. The light directing features are capable of directing light traveling from the core in a radial direction toward an outer surface of the diffuser tip for irradiating a material in proximity of the diffuser tip. An optical coupling material is disposed between the core and the diffuser tip. The optical coupling material and surfaces of the light directing features form boundaries upon which light rays traveling from the core are incident. The pattern of light directing features has a proximal portion, a central portion and a distal portion where a dimensional property of light directing features located at the proximal and distal regions is different than the dimensional property of light directing features located at the central region. The dimensional property is selected to provide a flattened light intensity profile during use.
