Patent number: 11950765Abstract: Multi-stage catheter device configured to navigate through complex narrow tissue openings such as lung bronchi pathway openings of 3 millimeters or less. The device comprises a proximal catheter portion containing a hollow torque shaft, with a distal catheter portion connected to the proximal portion by a rotatable coupler connected to this hollow shaft. The distal position of the proximal catheter can be controlled by up to four independently controlled proximal stage steering cables positioned outside of the shaft, and the shaft itself can be used to rotate the distal catheter about the rotatable coupler. The position of the distal end of the distal catheter can be further controlled by up to four independently controlled distal stage steering cables positioned inside of the hollow shaft. The device is tipped by a tool plate, which can be equipped with various sensors and other instruments, connected to the outside via other conduits.Type: GrantFiled: May 26, 2023Date of Patent: April 9, 2024Assignee: Syncrobotix, Inc.Inventor: Gregory P.

Patent number: 11925427Abstract: Computerized system and method of manufacturing an articulated surgical device. Surgical device pathway data (often from medical scans), target and entry point location data, and design parameters in computer memory are used to automatically design, and subsequently manufacture the customized device. The device typically comprises a plurality of units, which may have varying lengths and widths, connected to other units by at least one moveable joint. The device is configured to accommodate multiple pull cables, often running from the distal to the proximal end. These cables enable an operator, often using a proximal control device, to precisely control the orientation of the distal end as the device traverses a patient's body pathways. The distal end of the device may have an effector unit configured to perform a medical task. Design and manufacture are facilitated by use of AI computerized design methods and computer controlled (CNC, laser cutting, 3D printing) methods.Type: GrantFiled: March 19, 2023Date of Patent: March 12, 2024Inventor: Gregory P. Schmitz

Publication number: 20210322113Abstract: A joint device for a robotic surgery tool includes a yoke and two links movably coupled with the yoke. The yoke may include a circumferential base, forming a central opening and four cylindrical pivot bosses extending laterally from the base at ninety-degree intervals. A first link is movably coupled with a first set of two of the four cylindrical pivot bosses and extends from the yoke in a first direction, such that the first link pivots in a first plane relative to the yoke. A second link is movably coupled with a second set of two of the four cylindrical pivot bosses and extends from the yoke in a second direction, such that the second link pivots in a second plane orthogonal to the first plane. Thus, the joint device provides for movement in two opposed planes from one yoke.Type: ApplicationFiled: May 12, 2021Publication date: October 21, 2021Inventor: Gregory P. SCHMITZ

Patent number: 9924953Abstract: Described herein are elongate devices for modifying tissue having a plurality of flexibly connected rungs or links, and methods of using them, including methods of using them to decompress stenotic spinal tissue. These devices may be included as part of a system for modifying tissue. In general, these devices include a plurality of blades positioned on (or formed from) rungs that are flexibly connected. The rungs are typically rigid, somewhat flat and wider than they are long (e.g., rectangular). The rungs may be arranged, ladder like, and may be connected by a flexible connector substrate or between two or more cables. Different sized rungs may be used. The blades (on the rungs) may be arranged in a staggered arrangement. A tissue-collection or tissue capture element may be used to collect the cut or modified tissue.Type: GrantFiled: September 19, 2016Date of Patent: March 27, 2018Assignee: Amendia, Inc.Inventors: Gregory P.
