Abstract: A mouth-nose mask for reducing the transmission of pathogens via droplets of secretion is disclosed. The mouth-nose mask includes a central fold which defines a chin-nose line of the mouth-nose mask and separates the mouth-nose mask into two substantially congruent halves. A fastening means for fastening the mouth-nose mask to a wearer's ears or back of the head is attached to the ends of the two halves remote from the central fold. The mouth-nose mask includes at least two superposed layers of a filter material, the at least two layers defining the outer shape of the mouth-nose mask and being only partially joined to one another at their edges.

Abstract: The invention relates to an aspiration catheter for the aspiration of material from blood vessels. The aspiration catheter according to the invention comprises a tubular catheter wall (2) having a first distal opening (3) and a first proximal opening (4). These two openings (3, 4) are connected to each other by a first lumen (5). The aspiration catheter further comprises a tubular guide sleeve (6) having a second distal opening (7) and a second proximal opening (8). A second lumen (9) extends between these two openings (7, 8). The tubular guide sleeve is arranged within the first lumen (5), wherein the second lumen (9) extends coaxially to the first lumen (5). The second proximal opening (8) extends laterally through the tubular catheter wall (2). The tubular guide sleeve is connected to the tubular catheter wall (2) in a region (X) of the first distal opening (3) and in a region (Y) of the second proximal opening (8).
