Publication number: 20230157594Abstract: Transvaginal and/or transcervical fetal oximetry probes may be configured to take measurements in the endocervical canal of a pregnant mammal that may be used to determine a fetal hemoglobin oxygen saturation level using, for example, oximetry, pulse oximetry, and/or tissue oxygen saturation calculations. Transurethral fetal oximetry probes may be configured to be inserted into a urethra of a pregnant mammal and be positioned proximate to a wall of a bladder of the pregnant mammal proximate to the fetus. Once in position, the Transurethral fetal oximetry probe may take measurements that may be used to determine a fetal hemoglobin oxygen saturation level using, for example, oximetry, pulse oximetry, and/or tissue oxygen saturation calculations.Type: ApplicationFiled: March 24, 2021Publication date: May 25, 2023Inventors: NEIL PADHARIA RAY, RUSSELL DELONZOR

Publication number: 20220361774Abstract: Systems, devices, and methods for performing trans-abdominal fetal oximetry and/or trans-abdominal fetal pulse oximetry using physiological characteristics and/or a calibration factor may receive a physiological characteristic of a pregnant mammal and determine one or more potential impact(s) of the physiological characteristic on a behavior of an optical signal projected into the abdomen of the pregnant mammal Then a calibration factor for the optical signal responsively to the impact. The calibration factor may then be used to calibrate a fetal detected electronic signal so that a level of fetal hemoglobin oxygen saturation may be determined.Type: ApplicationFiled: July 24, 2020Publication date: November 17, 2022Inventors: NEIL PADHARIA RAY, MARK ANDREW ROSEN, ADAM JACOBS, RODNEY P.

Patent number: 9510898Abstract: A method of ablating a uterine fibroid using a particular trocar is disclosed. The trocar comprises a plurality of ablation stylets. The trocar is adjustable to assume a plurality of configurations, each of the configurations having the stylets extended to a different extent from the trocar. A region to he ablated is imaged, The size of the region to be ablated is noted. The size of the region to be ablated is compared to a matrix of known ablation regions, each of the known ablation regions being associated with one of the configurations of the particular trocar. The region to be ablated is associated with a most nearly matching known ablation region by comparison of the region to be ablated to the known ablation regions. A trocar is inserted into the uterine fibroid at a position, which more closely matches the position of the particular trocar with respect to the known ablation region. The stylets are deployed from the trocar to an extent corresponding to the configuration.Type: GrantFiled: August 18, 2013Date of Patent: December 6, 2016Inventors: Gordon Epstein, Bruce Lee, Russell Delonzor, Adam Hagmann, Richard Spero

Publication number: 20070156125Abstract: A medical device, such as a cryogenic biopsy device, includes a disposable unit and a reusable unit. The disposable unit, such as a treatment needle or probe, is at least partially insertable into the body of a medical subject and includes an encodable device for storing information. The reusable unit is connectable to the disposable unit and includes a controller. The disposable unit transfers the information to the controller in the reusable unit. The controller then directs activities of the medical device in response to the information stored in the disposable unit.Type: ApplicationFiled: December 30, 2005Publication date: July 5, 2007Inventor: Russell DeLonzor
