Patent number: 11350985Abstract: Hysteroscopic system includes a hysteroscope having a main body coupled to an extension portion. The extension portion may be a shaft configured to extend transcervically to a patient's uterine cavity. First, second, and third channels extend from the main body to a distal end of the extension portion. A fluid source is coupleable to a proximal end of the first channel, and a pressure sensor is coupleable to a proximal end of the second channel. A tissue resecting probe is configured for introduction through the third channel. At least one resistance feature is included which is configured to provide a selected level of resistance to axial sliding of the probe through the third channel while permitting rotation of the probe within the third channel.Type: GrantFiled: December 17, 2019Date of Patent: June 7, 2022Assignee: MINERVA SURGICAL, INC.Inventors: Aaron Germain, Csaba Truckai

Publication number: 20220151690Abstract: Methods, systems and devices for evaluating the integrity of a uterine cavity. A method comprises introducing transcervically a probe into a patient's uterine cavity, providing a flow of a fluid (e.g., CO2) through the probe into the uterine cavity and monitoring the rate of the flow to characterize the uterine cavity as perforated or non-perforated based on a change in the flow rate.Type: ApplicationFiled: November 22, 2021Publication date: May 19, 2022Applicant: Minerva Surgical, Inc.Inventors: Akos TOTH, Robin BEK, Dominique FILLOUX, Tejas N.

Publication number: 20220142697Abstract: Tissue is treated using a radiofrequency power supply connected to an applicator having a chamber filled with an electrically non-conductive gas surrounded by a thin dielectric wall. A radiofrequency voltage is applied at a level sufficient to ionize the gas into a plasma and to capacitively couple the ionized plasma with the tissue to deliver radiofrequency current to ablate or otherwise treat the tissue.Type: ApplicationFiled: January 14, 2019Publication date: May 12, 2022Applicant: Hermes Innovations LLCInventors: Akos Toth, Csaba Truckai

Patent number: 11324546Abstract: Tissue may be cut and extracted from an interior location in a patient's body using a probe or tool which both effects cutting and causes vaporization of a liquid or other fluid to propel the cut tissue through an extraction lumen of the cutting device. The cutting may be achieved using an electrosurgical electrode assembly, including a first electrode on a cutting member and a second electrode within a cutting probe or tool. Thus, over a first cutting portion, radio frequency current may help cut the tissue and over a second or over transition region, the RF current may initiate vaporization of the fluid or other liquid to propel the tissue from the cutting device.Type: GrantFiled: April 15, 2020Date of Patent: May 10, 2022Assignee: MINERVA SURGICAL, INC.Inventors: John H. Shadduck, Aaron Germain, Csaba Truckai, Kyle Klein, Michael D. Walker

Publication number: 20220125505Abstract: The tissue cutting device comprises an elongated assembly including both an outer sleeve and an inner sleeve. The outer sleeve has a tissue-receiving window, and the inner sleeve has a distal end which cuts tissue as the inner sleeve is advanced past the window. The tissue is received into a lumen of the inner sleeve, and the inner sleeve lumen is typically enlarged in a proximal direction to reduce the tendency of resected tissue to lodge therein. The tissue displacement member is optionally provided at a distal end of the outer sleeve to further aid in dislodging tissue which becomes captured in a distal end of the inner sleeve of the lumen.Type: ApplicationFiled: January 6, 2022Publication date: April 28, 2022Applicant: MINERVA SURGICAL, INC.Inventors: Aaron Germain, Kyle Klein, Benedek Orczy-Timko, John H. Shadduck, Michael D. Walker, Csaba Truckai, Balazs Lesko

Patent number: 11272835Abstract: A medical introducer includes an elongated tubular member having a proximal end, a distal portion, and a central lumen extending from the proximal end to a distal port in the distal portion. A frame structure is coupled to the distal portion of the elongated tubular member, where frame structure supports the distal portion of the elongated tubular member in a tapered shape and alternatively in a non-tapered shape. The elongated tubular member may include a rigid outer tube and a rigid inner tube carried in an interior lumen of the outer tube. The distal portion is typically a reinforced elastomeric tubular extension of the outer tube, and the reinforced elastomeric tubular extension may have a conical shape.Type: GrantFiled: November 8, 2018Date of Patent: March 15, 2022Assignee: Corinth MedTech, Inc.Inventors: George Chao-chih Hsu, Csaba Truckai

Patent number: 11259787Abstract: A medical instrument includes a tubular cutter extending along an axis and having a windowed outer sleeve and a moveable inner cutting sleeve. An ultrasound transducer is operatively coupled to the inner cutting sleeve in order to induce motion in the inner cutting sleeve to enhance cutting or resection of tissue by the inner cutting sleeve as it is reciprocated or otherwise moved past the cutting window. The instrument typically will include a motor drive configured to reciprocate and/or rotate the inner cutting sleeve relative to the windowed outer sleeve, usually at a reciprocation rate between 1 and 10 Hz.Type: GrantFiled: December 6, 2019Date of Patent: March 1, 2022Assignee: Hermes Innovations LLCInventor: Csaba Truckai

Publication number: 20220015620Abstract: Endoscopes include a shaft having a diameter extending about a longitudinal axis to a distal housing. An image sensor is carried by the distal housing, and a channel extends through the shaft and distal housing. A distal portion of the channel is adjustable or curved to accommodate introduction of a tool while maintaining a reduced shaft diameter. In some embodiments, a diagonal dimension of the image sensor when combined with a channel diameter is greater than a shaft diameter. In some embodiments, the distal housing is flexible to accommodate passage of a straight tool through a curved distal portion of a working channel. In some embodiments, a curved distal portion of a working channel may be reoriented to deflect a flexible tool.Type: ApplicationFiled: September 30, 2021Publication date: January 20, 2022Applicant: Meditrina, Inc.Inventors: Csaba Truckai, Daniel Truckai, Khoi Le, Kevin Moss, Britta Nelson, Nicholas Landgraf

Publication number: 20210401275Abstract: An endoscope includes a shaft having proximal and distal ends and a longitudinal axis therebetween. A handle is coupled to the proximal end of the shaft, and an image sensor is carried on the distal end of the shaft. A channel extends through at least a distal shaft portion and has a channel diameter, and a section of the channel is re-configurable between a constricted shape and a non-constricted shape to accommodate tools introduced therethrough. The combined diagonal dimension and channel diameter is usually greater than the outer shaft diameter. The image sensor may be connected to a connector on the housing by a first slack flex circuit and a lights source on the shaft may be connected to a connector on the housing by a second slack flex circuit.Type: ApplicationFiled: September 10, 2021Publication date: December 30, 2021Applicant: Meditrina, Inc.Inventors: Akos TOTH, Eugene Skalnyi, John H.
