Summary for Patent: 8,888,745

Title:	Applicator for inserting an implant
Abstract:	The invention pertains to an applicator (1) for inserting an implant, in particular a rod-like implant (2) containing an active substance, under the skin of a human or animal, comprising a housing (3), a cannula (6) extending from the housing (3), and a handle (15) for grasping and maneuvering the applicator (1) and the cannula (6) during insertion of an implant (2). In accordance with the invention, the handle (15) extends above at least part of the length of the cannula (6). Such a handle facilitates insertion of the cannula and/or accurate positioning of the implant.
