Abstract: According to the invention, an uterotubal implant device is provided. Said uterotubal implant device comprises at least two compressible self-expanding bodies which are composed of a grid structure and are coupled to one another in a longitudinal direction such that one body is arranged distally in the longitudinal direction and the other body is arranged proximally in the longitudinal direction, at least one of the bodies having a spindle- or funnel-shaped design.

Abstract: A tubular nonwoven structure as an active agent carrier (“sleeve”) for the atraumatic treatment of hollow organs, in particular applicable via a balloon catheter, as well as a method for the production thereof, wherein the sleeve is folded about a longitudinal sleeve axis in an initial state and is unfoldable in a final state for attachment to an inner wall of a hollow organ, the tubular sleeve is formed of first biodegradable polymer nanofibers and the folding of the sleeve is directed as pleating about a longitudinal sleeve axis, a medicinal active agent is incorporated into the first polymer nanofibers and/or is arranged in interspaces between the polymer nanofibers, and the first polymer fibers are formed such that the polymer fibers degrade over a period of 2 weeks to 3 months so that the active agent can be delivered to a hollow organ wall in this period of time.

Abstract: The invention relates to a tubular sleeve for the atraumatic treatment of hollow organs, wherein the sleeve is folded in an initial state and can be unfolded in order to lie against an inner wall of a hollow organ in a final state. The sleeve is characterized in that the sleeve is formed of an outer wall and an inner wall, which are arranged concentrically to each other, wherein the outer wall and the inner wall are tightly connected to each other at ends thereof in such a way that an approximately tubular compartment is formed in the region between the outer wall and the inner wall and the folding of the sleeve is directed about a sleeve longitudinal axis.
