  • Patent number: 10357271
    Abstract: A surgical instrument (10, 100) configured to facilitate gripping and manual adjustment by a left-handed or righted-handed user. The surgical instrument includes a rod (11) having a first end (12a) attachable to a working end (13, 113) of the instrument via a mount (16). The rod has a second end (12b) coupled to a handle (14) having rotational directionality for gripping by a first hand of the user. The handle is rotatable about the rod so as to allow the user to adjust an angular displacement of the user's finger relative to the working end, and a locking member (20, 146) prevents rotation of the handle relative to the rod when the beveled indent is optimally located relative to the working end.

  • Patent number: 10335187
    Abstract: Rotational atherectomy devices and systems can remove or reduce stenotic lesions in blood vessels by rotating one or more abrasive elements within the vessel. The abrasive elements can be attached to a distal portion of an elongate flexible drive shaft that extends from a handle assembly that includes a driver for rotating the drive shaft. In particular implementations, individual abrasive elements are attached to the drive shaft at differing radial angles in comparison to each other (e.g., configured in a helical array). The centers of mass of the abrasive elements can define a path that fully or partially spirals around the drive shaft. In some embodiments, a distal stability element with a center of mass aligned with the longitudinal axis is fixedly mounted to the drive shaft.
