The invention presented here overcomes the limitations of the prior art and provides a catheter introducing system by means of which bleeding can be prevented and wall trauma can be minimized. The innovative device combines a peel-away sheath introducer set with a splittable hemostasis valve and an integrated sealing system.
The new peel-away introducer set is composed of three coaxial arranged peelable cannulae: an access cannula, a pusher and a sealing cannula. The pusher and the sealing cannula are mounted on the access cannula in a movable manner. A collagen cuff is integrated into the sealing cannula in such a way that the collagen can be positioned by the pusher at the puncture site where the collagen acts as a surgical sealant. This system allows an effective sealing of the puncture wound after removal of the access cannula. In addition, the introducer set contains a splittable hemostasis valve to prevent reflux of liquid (e.g. blood) from the punctured vessel during the implantation procedure.
The present invention could be used for procedures where a device has to be introduced into a vessel of the human or animal body. As an example the sheath introducer can be applied to establish a fully implantable and telemetrically controlled blood pressure system comprising an implant with a sensor and a telemetry unit which is connected via micro-cable with the sensor.

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.
While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.
As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...
