Abstract: A device for positioning a probe in living tissue, the device including a casing having an underside for positioning on the tissue, the probe, which can be moved relative to the casing beyond the underside in an insertion direction to be inserted into the tissue, and a signal means carried by the casing such that it can be moved in the insertion direction to an end position, wherein the signal means slaves the probe when moving in the insertion direction.

Abstract: A device for inserting a cannula into tissue, including a cannula, a protective element which can accommodate said cannula, an operating element for moving the cannula out of the protective element, and a holder fixedly connected to the cannula. The invention encompasses a system for connecting a liquid supply to the cannula.

Abstract: An insertion head for medical or pharmaceutical uses including a housing with a side that can be positioned on tissue and a penetrating device with a tip, the penetrating device carried by the housing in a protected orientation in which the housing covers the tip and a penetrating orientation in which the tip protrudes, wherein the penetrating orientation is angled relative to the protected orientation.

Abstract: A membrane with at least one passage extending through an elastic material of the membrane, wherein when a cannula is inserted in the passage, the passage is expanded and the elastic material presses against the cannula and surrounds the cannula in a seal, wherein the membrane can be compressed relative to the passage, and wherein, in one embodiment, the passage exhibits a cross-sectional area having a long main axis and a short main axis perpendicular to the long main axis. The invention encompasses a membrane-cannula combination for biological and medical uses, and a membrane-connecting device combination for connecting a fluid guide and a catheter.

Abstract: A cannula, for introduction into a body tissue, the cannula flexible after introduction, and rigid below a critical temperature and flexible above the critical temperature. In a method for the introduction of the cannula into the body tissue, the cannula is cooled to a temperature below the critical temperature and introduced into the body tissue. After being introduced, the cannula is brought to a temperature above the critical temperature by warming and thus becomes flexible.

Abstract: The application relates to portable medical devices that can be placed on a patient's skin and that include a silicone-based adhesive for attaching the device to the skin removeably or releasably. In preferred embodiments, the adhesive is a silicone pressure-sensitive adhesive (PSA) or a silicone soft-skin adhesive (SSA).
