Patent number: 9314319Abstract: A transfer part for holding an implant has a clamping portion for clamping connection with the implant. The clamping portion has a radial groove, a clamping ring and a force transmission element. The clamping ring is insertable into the radial groove to directly engage with the implant. The force transmission element secures the clamping connection against rotation. An inner ampule for receiving and securing a transfer part for holding an implant has an upper fixing portion and a lower fixing portion. The upper fixing portion reaches to a large surface recess in the ampule for insertion and removal of the transfer part, and has a laterally open indentation enlarging towards the recess adapted for the closely fitting insertion of the transfer part. The lower fixing portion has a laterally open indentation towards the recess adapted to receive the implant.Type: GrantFiled: October 15, 2004Date of Patent: April 19, 2016Assignee: Straumann Holding AGInventors: Marcello Memmolo, Daniel Günter
