摘要： Ablation systems and methods detect and address distortion caused by a variety of factors. A method includes measuring a temperature curve at target tissue; applying ablation energy to the target tissue; determining a peak temperature on the temperature curve; if the peak temperature is greater than the predetermined peak temperature, determining a time at which the temperature curve crosses to a lower temperature; and if the determined time is greater than a predetermined time, generating a message indicating that the target tissue was successfully ablated. Another method includes determining a distance between a remote temperature probe and an ablation probe, applying ablation energy to target tissue, measuring temperature at the remote temperature probe, estimating ablation size based on the determined distance and the temperature measured by the remote temperature probe, and determining whether the target tissue is successfully ablated based on the estimated ablation size.

摘要： The present disclosure is directed to a fluid cooled ultrasonic surgical instrument and related systems and methods of use therefor. In some embodiments, the disclosed ultrasonic surgical instrument is adapted for used within an insufflated cavity or pneumoperitoneum of a patient. The instrument includes a housing having an elongate shaft, a waveguide disposed at a distal end of the shaft, a coolant inlet port defined in an outer surface of the housing, and a coolant pump disposed within the housing and configured to move coolant from the coolant inlet port to the waveguide. During use, insufflation gas from within the pneumoperitoneum is drawn into the instrument shaft by the coolant pump, and blown over the waveguide to provide cooling. The delivery of ultrasonic energy and activation of the pump may be controlled by a processor in response to user input and waveguide temperature.

摘要： A method for coupling a body conduit to tissue includes engaging an implant about an outer surface of a catheter. The implant receives a bioactive agent having tissue growth properties. The method involves inserting the catheter through the body conduit and into a tissue opening across a resected area, positioning the implant in the resected area, inflating a balloon to anchor the catheter within the tissue opening such that the implant bridges the body conduit and the tissue opening across the resected area, and maintaining the catheter and the implant in vivo to enable the bioactive agent to secure the implant in the resected area to permanently bridge the body conduit and the tissue opening.

摘要： An ultrasonic surgical instrument includes a transducer assembly having a distal engagement member and configured to supply ultrasonic energy. A waveguide defines a longitudinal axis and has a proximal engagement member configured to threadingly engage the distal engagement member. The waveguide is configured to transmit the ultrasonic energy therealong to a distal end thereof for treating tissue. A torque member is coupled to the transducer assembly and is disposed about the longitudinal axis. The torque member is selectively rotatable about the longitudinal axis and relative to the waveguide to threadingly engage the transducer assembly and the waveguide to one another. The torque member includes a plurality of fingers pivotably coupled thereto and movable between a closed position and an open position. In the open position, each finger extends substantially perpendicularly from the longitudinal axis to define a moment arm that facilitates the engagement of the transducer assembly and the waveguide.

摘要： A biopsy instrument for removing nodes such as lymph nodes may include one or more of a blade for mechanical cutting of the ducts that connect the node to surrounding tissue and/or an energy emitter for emitting energy to seal the ducts and/or contribute to the gentle removal of the node from its connecting ducts. The biopsy instrument may include a ring clamp assembly made up of two opposing ring structures that may be clamped together such that the desired tissue sample (e.g., a lymph node) is captured within the inside opening of the clamped rings. Connecting ducts may be severed using either a blade or energy emitted from the ring clamps.
