The jaw member is pivotally connected to the distal end of the outer tube, the distal end of the inner tube acting on the jaw member, and the inner tube sliding with respect to the outer tube and driving the jaw member to pivot with respect to the blade. A first abutting portion provided on the distal ends of the inner tube and the outer tube forms a support between the inner and outer tube, so as to avoid a radial clearance change between the inner tube and the outer tubes without affecting the relative sliding movement of the inner and outer tubes.Type: ApplicationFiled: April 14, 2024Publication date: August 29, 2024Applicant: REACH SURGICAL, INC.Inventors: Qiang YANG, Fengxian ZHENG, Yanyang LEI, Xiaoyun FAN, Sandong LI

Publication number: 20240285303Abstract: A surgical cutting device in otology for the production of a thin tissue or cartilage slice, has an elongate device body aligned along a longitudinal axis, a handle-like grip, and a cutting head with a cutting blade having a blade body with a sharp cutting edge. The cutting blade is arranged within a cutting window which is continuously open in a direction transverse to the direction of the longitudinal axis. The cutting blade is positioned in the cutting window so that its sharp cutting edge is aligned parallel to a transverse axis which extends perpendicular to the longitudinal axis and obliquely to the direction. The sharp cutting edge is positioned axially away from the blade body in the direction of the longitudinal axis towards the handle-like grip. The cutting blade is connected to the device body either rigidly or movably about the transverse axis.Type: ApplicationFiled: February 23, 2024Publication date: August 29, 2024Applicant: Heinz Kurz GmbHInventors: Thomas STIEGELE, Alexander SANDER, Matthias MERTENS

Publication number: 20240285307Abstract: Systems and methods involve abrading a patient lung airway wall to reduce mucus production therein. Exemplary techniques include rotationally and/or linearly oscillating an abrasive material against the airway wall so as to damage mucus producing tissues, for example by removing goblet cells, while destroying less than the entire airway wall. The abrasive material may be present on the surface of an expandable balloon body or another expandable device, which can be delivered to the patient treatment site via a bronchoscope. In some cases, the abrasion techniques can cause cell damage or death at a controlled or predetermined tissue depth.Type: ApplicationFiled: April 29, 2024Publication date: August 29, 2024Inventor: Mark L.

Publication number: 20240285308Abstract: A flexible drive shaft assembly is provided for an intravascular medical device, for example and without limitation, a blood pump, a rotational atherectomy device, or a rotational thrombectomy device. The blood pump embodiment provides an electric motor and a rotational impeller, with a rotational drive shaft disposed therebetween and configured to rotationally drive the impeller. The drive shaft is moved from an undeformed length to a deformed length when connected between the electric motor and the rotational impeller to provide a biasing force on the rotational impeller in the proximal direction to maintain the impeller in a desired axial or linear location. In other embodiments, drive shaft comprises a proximal section with a length and a spring constant and a distal section of relatively longer length and a relatively higher spring constant. In other embodiments, hypotube(s) and/or support mandrel(s) may be provided.Type: ApplicationFiled: May 9, 2024Publication date: August 29, 2024Inventors: Benjamin D. Haselman, Tristan A.
