Patent ID: 8864779

Claim:
A device for intracorporeal application of an auxiliary medical material, the device comprising: a hollow application tube for inserting the auxiliary medical material into a surgical area, the application tube having at least one window thereon, wherein the at least one window is spaced away from a distal opening of the application tube; and a winding insert configured to be inserted into the application tube, the winding insert having a distal portion onto which the auxiliary medical material is wound and a proximal portion that comprises a various catch steps, the various catch steps being spaced apart from each other in an axial direction of the winding insert such that each catch step marks a corresponding working step and a particular insertion depth of the winding insert inside the hollow application tube; wherein the application tube and the winding insert are configured such that: i) at a first catch step and a first corresponding working step, the auxiliary medical material can be inserted through the at least one window to wind onto the winding insert while the distal portion is completely inside the application tube; ii) at a second catch step and a second corresponding working step, the distal portion is inserted distally farther into the application tube than at the first catch step and the auxiliary medical material cannot be unwound through the at least one window; and iii) at a third catch step and a third corresponding working step, the distal portion and the auxiliary medical material extend through the distal opening of the application tube.
