Abstract: A device for guiding a drilling of a femoral head of a femur in femoral head resurfacing comprises a body defining a guide channel adapted to receive and guide a drilling component therein. Arms are pivotally connected to the body and biased toward one another, the arms each having a contact end extending below the body, the contact ends adapted to contact a femoral neck when the body is in a hovering position relative to the femoral head. Sensors produce a signal indicative of an orientation angle of each of the arms relative to the body. A processor unit calculates the orientation angles of the arms from the signal, and evaluates from the orientation angles an alignment of the body relative to the femur. A visual output produces a visual signal representative of said alignment. A method for aligning a drill guide device on a femur for subsequent drilling a femoral head with a guide channel in the drill guide device is also provided.

Abstract: A method for aligning a bone cutting guide on a tibia may involve coupling a cutting guide alignment device and an attached cutting guide with a tibia, adjusting the alignment device in a varus/valgus orientation, adjusting the alignment device in an anterior/posterior orientation, attaching the cutting guide to the tibia, and removing the alignment device from the cutting guide, leaving the cutting guide attached to the tibia. The adjustments to the alignment device may be made according to vertically and horizontally oriented laser lights emitted from the alignment device. As the alignment device is adjusted, the bone cutting guide attached to the alignment device changes position relative to the tibia.

Abstract: A package for use in holding, dispensing, and spreading a viscous substance, such as a condiment. The package may include a thin-walled rigid planar member with at least one centrally-located opening, a flexible membrane forming a sealed reservoir on one surface and a flexible membrane forming a removable cover over the opening on the opposing surface. The reservoir membrane may be permanently sealed to the rigid planar member about a perimeter that surrounds the perforation. The cover, reservoir membrane and the rigid planar member form a sealed cavity with which to safely store and transport the contents, with the cover being removed for dispensing and spreading purposes.
