How to use Technologies offered

A search for a cancer, preclinical stage, synthetic opportunity would use the selection "Therapeutics, Diagnostics" in 'Sector', 'Cancerous, neoplasmatic' in 'Disease Category', 'Drugs, Small Molecule' in 'Technology' and 'Preclinical' in 'Development Stage'.

Selection of 'Enabling Technology, Platform Technology' in 'Sector' will identify all kinds of research technologies that can be used in more areas of life sciences than pharmaceuticals only.

Each technology profile gives the name of a company or academic institute as source of the offer, and a link allowing to contact the potential licensor. In most cases a profile includes a pdf covering the available non-confidential information as well as detailed contact data.

Registered users can create non-public notifications profiles which will inform them about new 'Technologies Offered' entries fitting their needs as specified. In addition these profiles allow them to filter the available information more comfortably.


Methods of production of vascular prostheses

Organization name

EZN Erfinderzentrum Norddeutschland GmbH



The area of application of this invention is medical engineering, specifically in the area of biological vascular prostheses.

State of the art

Vascular prostheses can either be of biological origin or can be produced from synthetic material. Biological prostheses offer the advantage that they are not recognized by the patient as a foreign body and hence the ingestion of medication like anticoagulants can be avoided. In comparison to the state of the art, the invention allows for the production of complex bifurcated vascular prostheses from degradable polymers that serve as scaffolds for the body’s own cells.


The invention concerns a process for the production of bifurcated vascular prostheses by the polymer-processing technology electrospinning. For this purpose, a collector was designed that consisted of three mandrels of which two were hollow and could be fixed to the main collector by means of threaded rods.

The invention presents the advantage that the vascular prosthesis has a material structure that when seeded with cells from the body, possesses all the functions of the original tissue and does not act as a foreign body.

  • Production of complex geometries for biodegradable vascular prostheses
  • Deposition of fibers at angles and indentations
  • Possible to use almost any polymer
Property right
  • Application procedure initiated
