摘要:
Methods are disclosed for delivering energy to a body of a human or animal during a treatment procedure using an electrosurgical generator, a pre-set overall procedure time being defined for the treatment procedure, a ramp time being defined for a parameter to reach a pre-set threshold during the treatment procedure, the method comprising: measuring the parameter over time; and if the parameter has not substantially reached the pre-set threshold by the ramp time, setting a procedure extension time responsive to the time difference between the ramp time and the time at which the pre-set threshold was reached, and extending the overall procedure time by the procedure extension time.
摘要:
An apparatus is disclosed for removing tissue from a patient's body. The apparatus comprises a first elongate member defining a lumen and having an open distal end. The open distal end defines an opening and comprises a tip, where the tip is structured to reduce damage to tissue within the patient's body. The apparatus further comprises a tissue removal member disposed within the lumen of the elongate member. The tissue removal member comprises a distal end that is recessed from the tip of the elongate member. At least a portion of the tissue removal member protrudes beyond the opening to allow access to tissue distal to the opening. Related hollow members with blunt tips are also disclosed.
摘要:
Embodiments of a system and method are described for delivering energy to a body of a human or animal through a plurality of energy delivery devices. In some embodiments, a plurality of energy delivery devices are coupled to a generator and the number of energy delivery devices is automatically detectable. Furthermore, in some embodiments, the amount of energy delivered through the energy delivery devices is controlled, at least in part, by dynamically varying the amount of time that each energy delivery device is delivering energy.
摘要:
A method and apparatus are disclosed for detecting, analyzing and displaying errors in a energy source of a medical treatment system. Detected errors are analyzed to define further errors. Errors may be classified, for example, in response to severity, and prioritized. Prioritization may depend on a scope of the error, an order of occurrence, importance, or other factors.
摘要:
This invention discloses a cannula comprising an elongate shaft comprising a distal region and a proximal region and defining a lumen therebetween, and further comprising a wall defining at least one lateral aperture therethrough and a distal end defining at least one distal aperture. The distal region comprises an electrically exposed and conductive distal tip and the outer surface of the cannula between the distal tip and the proximal region is non-conductive.
摘要:
An electrosurgical apparatus having improved placement accuracy is provided. The electrosurgical apparatus comprises an elongate shaft having a proximal end, a distal end and at least one lumen therethrough, a stylet positioned within a lumen, a conductive tip at the distal end for delivery of energy to the tissue, an electrical coupling at or near the proximal end for flexibly coupling a power source control unit to supply energy to the conductive tip, a fluid delivery connection interface flexibly coupled at or near the proximal end for coupling a fluid delivery mechanism. The apparatus further comprises a temperature sensor. A method of delivering electrical energy to a target treatment area of an animal body is also provided.
摘要:
An electrosurgical apparatus for treating tissue comprises an elongate shaft including a proximal region, a distal region having an electrically conductive region and one or more lumens through the shaft. A stylet is located within one of the lumens for obturating at least a portion of an opening defined by a distal end of the elongated shaft. The stylet distal end has a sensor and may include an occluding component substantially surrounding and affixed to it. The elongated shaft and the stylet can possibly be configured to allow passage of fluid through the lumen while the stylet is located within the lumen. Related stylet configurations are also disclosed.
摘要:
An electrosurgical device comprising a means for impeding flow for delivering energy to a region of tissue is described. In addition, a method of treating the sacroiliac region of a patient's body by delivering energy is also described. The method includes the steps of inserting a probe into a target site within the sacroiliac region of a patient's body and delivering energy to the probe to treat tissue within the target site.
