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.

Profile

Invention

Drainages serve for the removement of fluids from body cavities by transluminal or percutaneous access. The size of the fluid-filled cavity can change during treatment, and consequently the length of the drainage needs to be adjusted. Current commercially available drainages have a predetermined geometry and length, or must be perforated and cut to the required length prior to use.

VariDRAIN has been developed in order to increase the variability of drainage geometry and power.

The invented drainage consists of two concentric tubes, which can be shifted against each other. According to require-ments the tubes can be rigid or flexible and preshaped in a broad range of variants. The outer tube is perforated and the particular holes can be selectively closed or opened by shifting the inner tube.

Thereby, the operator is able to adjust the length and power of the drainage according to the anatomic conditions and the course of the treatment. This invention thereby has significant advantages as compared to current commercially available drainage systems with regard to the variation range and capabilities.

Commercial Opportunities

On behalf of the RWTH Aachen University, PROvendis is seeking for interested companies for cooperation and/or licensing.

Current Status                        

A prototype has been built for demonstration. We are happy to inform you about the patent status.

Competitive Advantages

  • Variable length and power of the Drainage
  • Optimal removal of fluids at each time-point of treatment
  • Broad range of capabilities
