A stiffening tube is fixed to the distal end of the handle extending distally from the handle. A flexible outer tube is fixed to the stiffening tube and extends distally therefrom. A cut portion of the flexible outer tube has a plurality of cuts positioned therealong. In a first configuration, the flexible outer tube extends parallel to or in alignment with the stiffening tube, but in a second configuration, the flexible outer tube is curved at the cut portion. The plurality of cuts may be arranged into two patterns. Each cut arranged in a first pattern is offset at an angle from each cut arranged in a second pattern. The pattern, shape, and size of the cuts determines the movement of the flexible outer tube to the second configuration.

  • Patent number: 10517631
    Abstract: The invention provides a rotational atherectomy device having, in various embodiments, a flexible, elongated, rotatable drive shaft with a system of eccentric abrading heads attached thereto. At least part of the eccentric enlarged abrading heads in the system have a tissue removing surface—typically an abrasive surface. In certain embodiments, the abrading heads may be at least partially hollow. Preferably the eccentric enlarged abrading heads have centers of mass spaced radially from the rotational axis of the drive shaft, facilitating the ability of the system of eccentric abrading heads to work together to open the stenotic lesion to a diameter substantially larger than the outer resting diameter of the enlarged abrading heads when operated at high speeds. Therefore, certain embodiments comprise a system having unbalanced centers of mass to not only stimulate greater rotational diameters but also arranged in a manner whereby a debris-removing augering effect occurs.

  • Patent number: 10363615
    Abstract: This document provides orthopedic and dental devices and methods for their use. For example, novel bone drills and dental drills are described. The bone and dental drills have at least some centers of mass that are offset from the drills' axis of rotation. Accordingly, the bone and dental drills may rotate and cut using a precessional pattern of motion. The design facilitates bone cutting, chip formation and hauling capacity, irrigation and bone harvesting. In some embodiments, the bone chips are collected in a removable apparatus fixed to the distal portion of the drill, and the collected bone chips can be used for bone grafting.

  • Patent number: 10314633
    Abstract: A system for augmenting a bone structure. A shape memory device includes a deflectable distal segment including temperature-dependent memory metal material. The shape memory device is slidably received within a guide cannula. The deflectable distal segment may include a substantially longitudinally straightened form, such as when subjected to a force from the guide cannula. The deflectable distal segment forms a first deflected shape having a first bend away from said straight longitudinal axis at a first elevated temperature greater than an initial temperature, and forms a second deflected shape having a second bend away from said straight longitudinal axis at a second elevated temperature greater than said first elevated temperature. The shape memory device may create voids within the bone structure with the deflectable distal segment at the first and/or second bends. Methods for positioning a shape memory device within a bone structure are also disclosed.

  • Patent number: 9687254
    Abstract: Instrument and method for removing material from an intervertebral disc. The instrument includes outer and inner tubular members. The outer tubular member defines a passage and a cutting window. The inner tubular member is coaxially disposed within the passage, and defines a central lumen and a cutting tip. The cutting tip forms an open mouth having a plurality of teeth. Upon assembly, the cutting tip is exposed within the cutting window combining to define a shaving head. A manual decorticating implement is coupled to the outer tubular member and defining a scraping surface. A powered handpiece is coupled to the inner tubular member, and the shaving head is inserted into an intervertebral disc and positioned such that the cutting tip contacts targeted material (e.g., nucleus, annulus and/or end plate). The handpiece is activated to rotate the cutting tip relative to the cutting window. Contacted material is sheared between an edge of the cutting window and the teeth of the cutting tip.
