  • 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: 9504454
    Abstract: The transoral repair of choanal atresia is a method for the surgical repair of choanal atresia that uses a transoral approach. The procedure includes the use of a curved drill, a curved shaver, curved grasping forceps, and a suction irrigator. After endotracheal intubation, a retractor is inserted to retract the tongue. A 120° angled telescope is inserted behind the soft palate into the nasopharynx to visualize the posterior choanae. A curved drill is used to drill the atretic plate from the vomer medially to the lateral pterygoid plate laterally. The drilled section of the atretic plate is removed to clear the obstruction.

  • Patent number: 9386837
    Abstract: A skin care device comprising a handle and swappable heads connected via a magnetic drive. Avoidance of a mechanical coupling between the handle and the head enhances safety. The magnetic power is converted to electrical power to operate the LEDs and anything else needing electrical power as well as mechanical forces releasing therapeutic cream upon the consumer's skin. The device may further apply RF to the skin for complementary treatment. Using the magnetic drives allows the transfer of power without using serrated gears and because there are no electrical connectors allows using swappable heads on the same handle in humid or wet conditions. The handle is charged inductively.

  • Patent number: 9339345
    Abstract: A cutting apparatus for joint cutting system using robot includes a shaft combined with a motor in a part of a robot arm, a cutter having a cutting head at the end of the shaft, a sleeve in which the shaft is inserted, and a cutter support member having a sleeve base where the sleeve is fixed, characterized in that the sleeve is a standalone member of a hollow bar with a center hole and is separable from and combinable with the sleeve base. The sleeve and the sleeve base are so separable that it is possible to reinforce the strength of the sleeve, which retrains the bending force to the sleeve, though the diameter of the sleeve is minimized.
