Device and method to extract material of a material reservoir

Abstract

A device to extract material of a material reservoir has at least one guide tube with internal space and with an inner wall surrounding the internal space; at least one sled that can implement a sled translation movement in the inner space along a longitudinal alignment of the guide tube; and at least one collection unit with collection surface to collect the material. The collection unit and the sled are coupled to one another such that the sled translation movement of the sled leads to a collection translation movement of the collection surface of the collection unit, and such that the collection surface can be inserted into the material reservoir and be withdrawn from the material reservoir. A rotation mechanism that is operated manually or automatically can be provided with which a wire, which acts as a collection device, can be displaced in vivo over a length of 1 mm to up to 2 cm within a venous cannula. The invention is used in medical technology, for example, to collect cells from a reservoir in the form of a bodily fluid.
