Publication number: 20240148988Abstract: A method includes applying an actuating voltage to a solenoid for a first time span to actuate the solenoid against a bias. The method includes lowering voltage applied to the solenoid to a holding voltage that is lower than the actuating voltage to hold the solenoid against the bias for a second span of time. The solenoid has a coil to which the actuating and holding voltages are applied. The coil is rated for continuous operation at a rated voltage. The actuating voltage is above the rated voltage.Type: ApplicationFiled: March 7, 2022Publication date: May 9, 2024Applicant: Conmed CorporationInventor: Michael L. Koltz, Jr.

Publication number: 20240123166Abstract: A manifold assembly for a surgical gas delivery system is disclosed, which includes a manifold body including an inlet port for receiving gas from an outlet side of a compressor and an outlet port for recirculating gas to an inlet side of the compressor, a bypass valve communicating with the inlet port and the outlet port of the manifold body, an air ventilation valve for dynamically controlling the ingress of air from atmosphere, a smoke evacuation valve for dynamically controlling the egress of gas from the manifold assembly when the gas delivery system is operating in a smoke evacuation mode, and a gas fill for dynamically controlling the receipt of gas from a source of surgical gas.Type: ApplicationFiled: December 11, 2023Publication date: April 18, 2024Applicant: Conmed CorporationInventor: Michael L. Koltz, JR.

Publication number: 20230017125Abstract: A power delivery approach for delivering power to an electrosurgical vessel sealer when the jaws of the sealer surround tissue to be desiccated. Power delivery commences at a starting point that is at least 40 Joules and then decreases over a first predetermined period of time to a predetermined minimum power level to provide approximately 15 Joules in total. When the predetermined minimum power level is reached, power is then continuously increased over a second predetermined period of time to fully desiccate the tissue. Power delivery is terminated prior to over-desiccation of the tissue.Type: ApplicationFiled: December 11, 2020Publication date: January 19, 2023Applicant: Conmed CorporationInventor: Michael L. Koltz, JR.

Publication number: 20220273390Abstract: A force limiting apparatus for a surgical instrument to prevent too much force being applied to the jaws of the instrument. The instrument has a body with a drive shaft coupled to a pair of jaws, a bearing tube secured to the drive shaft, and a pair of tracks carrying a pivot pin that is biased into one end of the track. A lever is coupled to the pivot pin and abuts the bearing tube to move the bearing tube and close the jaws when squeezed by a user. If the lever is over actuated, the pivot pin will slide along the track against the bias of the spring assembly with the lever pivoting about the bearing tube rather than the pivot pin. As a result, the additional movement of lever does not result in any addition force being transmitted to the drive shaft via the bearing tube.Type: ApplicationFiled: July 28, 2020Publication date: September 1, 2022Applicant: Conmed CorporationInventors: Mason Williams, Michael L. Koltz, JR.

Publication number: 20220241003Abstract: A coating for the electrode of an electrosurgical instrument that increases the capacitance of the electrode. The coating comprises a high permittivity material such as barium titanate, lead zirconate titanate, calcium copper titanate, or a conjugated polymer. The coating may have a thickness of 0.0016 inches and can be included with one of more insulative layers.Type: ApplicationFiled: March 27, 2020Publication date: August 4, 2022Applicant: Conmed CorporationInventor: Michael L. Koltz, JR.

Publication number: 20200330149Abstract: An electrosurgical device having a pair of jaws, at least one electrode supported by one of the pair of jaws, and a polymer mat positioned in covering relation a portion of the at least one electrode. The polymer mat comprises a plurality of polymer fibers having an average width of between 1 and 100 micrometers. The polymer mat has a porosity of between 6E-10m2 and 2.5E-7m2. Between 10 and 90 percent of the electrode may be exposed.Type: ApplicationFiled: April 20, 2020Publication date: October 22, 2020Applicant: Conmed CorporationInventor: Michael L. Koltz, JR.

Patent number: 9408653Abstract: A powered screwdriver system includes an electric ratchet. In accordance with one aspect, the powered screwdriver system includes a driver housing and includes a motor disposed within the housing. A working end provides a rotational output and is mechanically coupled to the rotor. A power source provides power to the motor. A controller receives signals representative of a motor condition and, based on the received signals, controls the motor in a manner providing the electric ratchet.Type: GrantFiled: July 21, 2014Date of Patent: August 9, 2016Assignee: Medtronic Xomed, Inc.Inventors: Christopher L. Fair, Michael L. Koltz, Jr.

Patent number: 9289541Abstract: A surgical fluid manager includes a pump releasably engageable to tubing and a user interface. The user interface is configured to enable finger-touch selection of a fluid flow rate through the tubing and configured to operate in at least one of a first mode or a second mode. In the first mode, the flow rate is controlled via direct selection of one of a plurality of selectable digital numeric values, while in the second mode the flow rate is controlled via user selection of one alphanumeric identifier within a scale of alphanumeric identifiers. Each respective alphanumeric identifier directly corresponds to just one instrument size within a scale of instrument sizes.Type: GrantFiled: August 22, 2008Date of Patent: March 22, 2016Assignee: Medtronic, Inc.Inventors: Gerould W. Norman, Charles F. Scott Carpenter, Michael L. Koltz, Jr., Stephen R. Viviano
