Patent number: 7494492Abstract: A compact hand held device is provided that can be safely used by those suffering from acne, blemished skin or fine wrinkles. The hand held device includes an on/off switch and a button that pulses the device when it is placed on the target site. A battery within the device powers a circuit board and drives a short pulse of current through a heating element, which heats up to approximately 300° C. in less than 0.1 sec. Thermal conduction transfers the heat to the skin and causes a biological response that accelerates acne clearing, treats blemished skin or fine wrinkles. The total heat transferred is low enough to prevent burns.Type: GrantFiled: August 30, 2005Date of Patent: February 24, 2009Assignee: Therative, Inc.Inventors: Luiz B. Da Silva, George Choi

Patent number: 7491180Abstract: A method of determining the size and/or placement of a prosthetic disc in a disc space between adjacent endplates of two vertebrae in a selected spinal area, comprising: using a computer to identify the disc space parameters of height, width, depth and lordosis between the adjacent vertebral endplates; using a computer to create an artificial volume corresponding to an actual prosthetic disc that can be positioned in the disc space in accordance with a manufacturer's size and lordosis specifications for prosthesis; using a computer to determine the center of the disc space and the center of rotation of the prosthetic disc volume; using a computer to position the prosthetic disc volume in the disc space such that the center of rotation of the prosthetic disc volume is positioned posterior to the center of the disc space; and using a computer to determine the prosthetic disc volume that fits within the disc space in accordance with a surgeon's or manufacturer's specification for prosthesis.Type: GrantFiled: June 27, 2007Date of Patent: February 17, 2009Inventor: Hector O. Pacheco

Patent number: 7491206Abstract: An adjustable drill guide is provided that can be used to deliver a cross pin at a distance near the entrance to the femoral bone tunnel during ligament surgery. The cross pin positioned at the joint line, or tunnel opening, compresses and secures the graft within the bone tunnel, thereby preventing the graft from swaying back and forth post surgery when the joint is in motion. The adjustable drill guide assembly comprises a guide frame that includes an arm portion and a base portion that extends transversely to the arm portion. A rod member connects to the base portion for extending into the hone tunnel of the bone. Also included is a guide member configured for connection to the arm portion. The guide member is configured to be in moveable and lockable disposition along a length of the arm portion.Type: GrantFiled: June 27, 2003Date of Patent: February 17, 2009Assignee: Ethicon, Inc.Inventors: Gregory R. Whittaker, Thomas C. May

Patent number: 7481815Abstract: A novel coplanar X-ray guided method and aiming arm device for insertion of distal locking screws in intramedullary bone nails. Radiopaque target markers in the aiming arm enable the easy positioning of an X-ray source such that an X-ray beam is coplanar with the aiming arm transverse holes. After the X-ray source is accurately oriented, a single X-ray snapshot is enough to assess the exact distortion of the implanted intramedullary nail. The X-ray beam need not be coaxial with the nail holes. The aiming arm includes a mobile portion and a fixed portion fastened to the nail, and the aiming arm can be adjusted, displacing the mobile portion over the fixed portion, to compensate for the distortion of the intramedullary nail caused by implantation in bone.Type: GrantFiled: September 23, 2004Date of Patent: January 27, 2009Assignee: Synthes (U.S.A.)Inventor: Alberto Angel Fernandez
