Patent number: 10357314Abstract: A device for assisting in the positioning and sizing of an implant includes an elongate member and a block. The elongate member has length indicia at axial locations along a length for measuring a first distance from a predetermined datum of the elongate member. The block is attached to and movable along the elongate member. The block includes width indicia for measuring a second distance in a direction transverse to the first distance. A method for assisting in the positioning and sizing of an implant includes moving the elongate member along the block to axial locations along such member to determine an appropriate width and depth of insertion of the implant.Type: GrantFiled: July 8, 2015Date of Patent: July 23, 2019Assignee: Stryker European Holdings I, LLCInventors: Mael Cocaign, Julien Borgnard, Franck Day, Yogesh Pathapati, Oliver Ammann, Philippe Lehmann, Salman Chegini
