Patent number: 11890259Abstract: An occlusion clearing device for a patient has a housing with a motor(s) that generates repetitive motion, which is reciprocating, rotational or both. A clearing stem including a sheath that has a lumen, wherein aspiration is conducted through the sheath lumen. A wire is located in the sheath lumen and receives repetitive motion from the controller. The sheath terminates in a sheath end having at least one sheath opening. The wire terminates in a wire tip, which may be flat, helical, or tubular. The wire tip is positioned within the sheath end, in proximity to the sheath opening(s), and movement of the wire tip and/or sheath end relative to each other creates shearing forces that break up an adjacent occlusion.Type: GrantFiled: March 4, 2019Date of Patent: February 6, 2024Inventors: Roger B Bagwell, Ryan S Clement, Katherine M Erdley, Maureen L Mulvihill, Casey A Scruggs, Douglas R Dillon, Timothy J Higgins

Patent number: 11793543Abstract: An automatic insertion device and method of using the same is provided. A vibrator and an extender are connected to a penetrating member and are both in electrical communication with a controller. A detector identifies a subcutaneous target for insertion and the insertion angle, distance and trajectory for the penetrating member are calculated. The vibrator provides vibrations to the penetrating member and the extender advances the penetrating member for insertion. The vibrator and extender are in electrical communication with one another during the insertion process and adjustments to the insertion speed are made based on feedback of vibrational load encountered by the vibrator during insertion, and adjustments to the vibrations are made based on feedback of insertion load encountered by the extender during insertion. Iterative samples are taken to constantly adjust the operation of one motor based on the operations and feedback from the other motor.Type: GrantFiled: April 1, 2020Date of Patent: October 24, 2023Assignees: Obvius Robotics, Inc., Baylor College of MedicineInventors: Roger B.

Publication number: 20170080166Abstract: A system, device and method for insertion of a penetrating member into tissue is disclosed, which may be handheld and automated. A detector obtains data regarding subdermal locations of tissue structures, including cavities such as blood vessels. A processor calculates the distance between a preselected target point below the tissue surface, such as within a blood vessel, and the tissue surface, and adjustment data for vertical, angular and extension adjustment of the penetrating member. Vertical, angular and extension actuators carry out the adjustments in real-time as calculated and directed by the processor. Changes in the location of the target point result in automatic recalculation and adjustment by the processor and various actuators. A vibrational actuator induces vibration to the penetrating member during insertion, overcome tissue deformation and vein rolling. A guidewire may be inserted through or by the device, for dilator and catheter insertion once the penetrating member is removed.Type: ApplicationFiled: September 16, 2016Publication date: March 23, 2017Applicants: Actuated Medical, lnc., Baylor College of Medicine, Texas Heart instituteInventors: Roger B.

Publication number: 20160374723Abstract: A medical device for reducing the force necessary to penetrate living being tissue using a variety of reciprocating motion actuators. The reciprocating actuator drives a penetrating member, such as a needle, through the tissue at a reduced force while the device detects the passage of the penetrating member through the tissue. Upon passage of the penetrating member through the tissue, a feedback system monitors electromechanical properties of a control signal of the device and automatically modifies control based thereon, e.g., electrical power to the reciprocating actuator is automatically terminated.Type: ApplicationFiled: September 7, 2016Publication date: December 29, 2016Applicant: Actuated Medical, lnc.Inventors: Paul L.

Publication number: 20160303360Abstract: A transdermal delivery system including a first passive portion containing a substance for delivery in a reservoir and a second active portion that includes an ultrasonic source. The ultrasonic source includes piezoelectric element(s) that receive electrical stimulation and move radially. A support member fixed to one side of the piezoelectric element(s) restricts movement at that side, so the opposite side expands and contracts. A fulcrum attached to the support member opposite of the piezoelectric element(s) provides an anchor point about which the piezoelectric element(s) bends and flexes upon electrical stimulation. This provides a low ultrasound frequency with a smaller sized transducer than previously known. The active portion is applied to provide electrical stimulation for a certain length of time and removed, whereas the passive portion may remain for a longer duration. A feedback loop also monitors and adjusts the electrical stimulation to maintain a uniform or constant resonance frequency.Type: ApplicationFiled: April 15, 2016Publication date: October 20, 2016Applicant: Actuated Medical, Inc.Inventors: Maureen L.
