  • Method and implant for stabilizing two bone portions separated by a cut or fracture
    Patent number: 10335219
    Abstract: In a human or animal patient, two bone portions separated by a cut or fracture are stabilized in a desired position relative to each other by bringing the two bone portions into this desired position, by pulling them against each other, by providing an opening having a mouth on a bone surface and reaching across the cut or fracture and walls in both bone portions, by inserting an implant into the opening and anchoring the implant in the walls of the opening with the aid of a material having thermoplastic properties and energy transmitted into the implant for in situ liquefaction of at least part of the material having thermoplastic properties. One exemplary application of the stabilizing procedure concerns the two tibial bone portions separated by tibial plateau leveling osteotomy in a canine patient suffering from cranial cruciate ligament damage or rupture in a stifle joint.

  • Wound retractor device
    Patent number: 10278688
    Abstract: A wound protector and retractor device 1 comprises a sleeve 2, a distal member provided by a distal ring 3 of resilient material and a proximal member provided by a proximal ring 4. The sleeve 2 is led around the ring 3 and is free to move axially relative to the distal ring 3 somewhat in the manner of a pulley. The proximal ring 4 is fixed to the sleeve 2, in this case at the proximal inner end thereof. The sleeve 2 terminates in a handle or gripping portion which is reinforced by a gripping ring 15. The sleeve extends from the proximal ring 4 and the distal ring 3 is contained between inner and outer layers 2a, 2b of the sleeve 2. The resilient distal ring 3 is scrunched up and inserted through the incision 6. The sleeve 2 is then pulled upwardly. On pulling of the sleeve 2 upwardly the outer layer 2b is pulled up while the inner layer 2a is drawn around the proximal ring 3.

  • Double threaded guidance or stiffening wire for multiple use vertebral augmentation (VA) balloon
    Patent number: 10278755
    Abstract: A catheter device that includes a double-threaded guidance wire that allows multiple use of a compliant cavity creation device (i.e., treatment of more than one level).

  • Laryngoscopes
    Patent number: 10278571
    Abstract: A laryngoscope has a blade pivoted to a handle, and a light emitter lamp on the blade powered from a battery power source. A block formation at the rear end of the blade, at which it is pivoted to the head of the handle, incorporates a power source housing for the battery. The power source housing has a cover flap which cannot be opened in the operating position of the blade, but can be opened for removal of the power source in the folded position, or with the blade detached. This facilitates disposal and recycling. Electrical connectors lead from the power source housing to the light emitter lamp, and the rear end block of the blade has an external switch actuator which engages the head of the handle when the blade is extended to turn on the lamp. The power source, electrical connectors and light emitter may be combined into a discrete lighting module casing incorporated in the blade.

  • Apparatus and method for sinus lift procedure
    Patent number: 10258444
    Abstract: An osteotome for sinus lift procedures includes a body interchangeable with various handles. The body includes a shaft that is releasably received into the handle, and a tip portion. The tip portion may be directly utilized for ridge expansion/bone compression, or a succession of tip members may instead be received thereon to provide suitable diameter escalation to create the socket. A conduit in the tip portion interconnects with a conduit in a hydration port and a conduit in a tip member. A hose couples the hydration port to a syringe, to deliver fluid out the tip member to lift the membrane. Graduated syringe markings permit delivery of measured fluid quantities to control the amount of lift. A second hydration port is coupled to a graduated cylinder through a valve, which is opened after lifting is complete, to measure the fluid released. A loss of fluid measured indicates a sinus tear.

  • Scleral depressor
    Patent number: 10251634
    Abstract: A scleral depressor includes an elongated handle defining a first axis. An extension member has one end attached to the proximal end of the handle and includes a blade at the remote end thereof. The extension member defines a second axis and extends from the handle at approximately 90° thereby defining a plane. A bulbous or cylindrically shaped blade located at the remote end of the extension member has its rounded surface extending out of the plane. By properly manipulating the handle, such as by rotating the same, the rounded surface of the blade is used to depress the sclera.
