Publication number: 20210322108Abstract: A system and method for controlling the insertion of a medical tool, such as a needle, into a subject's body based on measurements of an interaction parameter associated with the interaction between the tool and a bodily tissue, such as the forces exerted on the tool during insertion. The system comprises an insertion device, at least one sensor configured to measure the interaction parameter and at least one processor configured to receive sensor measurements, detect one or more predefined patterns in the sensor measurements and control an operation of at least one of the insertion device and an imaging device, upon detecting the predefined patterns. The processor may be configured to compare the actual correlation between the sensor measurements and an insertion parameter, such as insertion depth, with an expected correlation, and determine if the medical tool is following its pre-planned trajectory based on the result of that comparison.Type: ApplicationFiled: May 18, 2021Publication date: October 21, 2021Inventors: Moran SHOCHAT, Ofer ARNOLD, Shraga Nahum GOLDBERG

Patent number: 8357151Abstract: Tissue ablation systems and methods are provided. Ablation energy (e.g., radio frequency energy) is delivered to the tissue and a physiological parameter (e.g., impedance and/or temperature) indicative of a change in moisture concentration of the tissue is sensed. The ablation energy is alternately pulsed on and off to generate an energy pulse train, with the ablation energy being pulsed on if the sensed physiological parameter crosses a threshold value indicative of an increase in the moisture concentration, and being pulsed off if the sensed physiological parameter crosses a threshold value indicative of a decrease in the moisture concentration.Type: GrantFiled: March 18, 2012Date of Patent: January 22, 2013Assignee: Boston Scientific Scimed, Inc.Inventors: S.

Patent number: 6692493Abstract: Relief of urethral obstruction is achieved by heat ablation of prostatic tissue by an ablation electrode passed within the urethra to a position in the prostate near the point of urethral obstruction. The electrode is coupled to a high frequency power supply to ablatively heat the urethra and the prostatic tissue near the urethra. Image guidance of the electrode placement is monitored by an imaging device. The temperature of the tissue is sensed at the electrode to control the high frequency heating energy and ablation process. The electrode has a blunt tip to help prevent piercing of the wall of the urethra during insertion of the electrode into the urethra through the penis and the positioning of the electrode tip near to the point of urethral obstruction. Several forms of electrodes, apparatus, and methods accommodate the specific objectives.Type: GrantFiled: August 26, 2002Date of Patent: February 17, 2004Assignees: Cosman Company, Inc., The General Hospital CorporationInventors: Francis J.
