    摘要： A medical probe for the heating of soft tissue, such as collagen tissue, wherein the medical probe has an elongated body with a proximal and distal end, a heating source, an RF electrode. Optional components include a thermocouple, and an insulative sleeve. The probe's elongated body is preferably hollow and flexible. The RF electrode and the heating source are powered by independently controlled power sources and cooperate to maintain a constant and smooth temperature to the distal end of the RF electrode. The heating source may be a contained liquid, such as saline, or an electrothermal mass, such as a ferrite, a toroid, a resistive element, or the like. Current induced from the conductor to the heating source creates heat in the heating source. The thermocouple measures the temperature of the heating source and adjusts the power to the conductor to maintain the heating source's temperature.

    摘要： An electrosurgical aspiration instrument that permits aspiration of an area being treated by the instrument. The instrument is coupled at a proximal end to a power source and includes an energy application surface area at a distal end. The power source supplied energy to the energy application surface area such that the distal end of the instrument may apply energy to the treatment area to modify the characteristics of biological material, such as biological tissue in the area. An aspiration lumen is formed through the instrument with an opening through the energy application surface area. The energy application surface area is configured to reduce blockage of the opening. Accordingly, aspiration may be performed simultaneously with electrosurgical treatment whereby unwanted matter such as by-products, biological debris and excess fluid is removed from the treatment area. The electrosurgical aspiration instrument also permits both functions to be performed at different times, with the advantage of not requiring instruments to be switched on during the treatment procedure or removed from the treatment site.

    摘要： A surgical probe for use in a hollow vessel or other region of the body which comprises a multi-lumen catheter having a transparent, non-compliant balloon coupled to the distal end, such that the balloon has a known shape when inflated. A direct visualization scope is provided in a first lumen of the multi-lumen catheter providing direct visualization into the hollow vessel through the non-compliant balloon. An adapter is coupled to a second lumen of the multi-lumen catheter near the proximal end to supply a transparent fluid through the second lumen to inflate the balloon to the predefined shape. In this aspect, the balloon operates to clear the scope tip by pressing tissue on the walls of the hollow vessel out of the way of the end of the scope. This provides the user of the device a consistent clear view of the tissue at the tip of the scope. A fiber optic is provided in a third lumen of the multi-lumen catheter to deliver light energy to the hollow vessel through the non-compliant balloon. A mechanism is provided for positioning the light emitting tip of the fiber optic within the balloon to establish a known propagation distance to the surface of the balloon for the light energy emitted from the light emitting tip.

    摘要： A fiber optic radiation transmission system is provided in which an optical fiber and a radiation source are connected to establish optical communication therebetween. Additionally, a connecting system is provided for connecting an optical fiber and a radiation source such that optical communication is established therebetween. The systems include a connector which carries the optical fiber therein. The connector is extendable within the system toward the radiation source to bring the optical fiber into optical communication with the radiation source. More particularly, the systems are configured in such a way that when the connector is extended sufficiently within the system, it seats the optical fiber relative to the radiation source under bias, thereby establishing a reliable optical connection. Once the optical connection is thus established, the connector engages a connection port associated with the radiation source to secure the system in a fully connected configuration appropriate for use. Thus, in a method of using such a system, the user simply extends the connector until the connector engages the connection port. The present invention thus provides efficient and reliable systems in which optical communication is established between an optical fiber and a radiation source.

    摘要： Methods and apparatus are described for irradiating living tissue via a cavity or lumen, using an inflatable balloon applicator. In a preferred embodiment the applicator balloon has a balloon skin with x-ray contrast material in relatively low concentration, so that an outline of the balloon will appear sharply when imaged externally. In another preferred embodiment the balloon catheter has a drain for withdrawing liquids from the cavity, which may include channels or texture on the exterior of the balloon. Methods are described for using a switchable miniature x-ray tube, variable as to voltage and current, to achieve accuracy in an isodose profile.

    摘要： A device and method of use for securing and coring of tumors within the body during a biopsy of the tumor, specifically breast tumors. An adhesion probe for securing the tumor is described. The probe secures the tumor by piercing the tumor and providing a coolant to the distal tip to cool the tip. The cooled tip adheres to the tumor. A coring instrument adapted for cutting a core sample of the tumor is described. The instrument is provided with a cannula that can cut a core sample of the tumor. The instrument is adapted for use with the probe with the probe fitting within the cannula. The instrument can be used in conjunction with the probe to secure and core a sample of the tumor for biopsy.
