New method for producing an innovative cannula used for spinal anaesthesia

1. Summary
The invention relates to a patented method for producing an innovative cannula in one single operation. The cannula can through its unique geometry increase patient compliance for spinal anaesthesia. The production method facilitates automated production of the cannula and can thereby decreases the manufacturing costs. Thus, an acquirer of the patent will be able to offer an innovative medical technology product that enables less patient complication to a reasonable price and still keep the margins.
2. Technology
The new cannula for spinal anaesthesia is provided with a rigid tube (2) whose distal end (6) gradually tapers in the direction of the tip (4) and comprises a sideways placed opening (8) through where the anaesthetic fluid exits. Thanks to the unique geometry, the new cannula decreases patient complications like post spinal headache caused by the older open cannulas that punches out tissue, or the required deep insertion of conventional pencil point cannulas which might injure nerve fibres. The new production method is characterized by the deforming or bending of the cannula's angular zone, which makes it possible to produce the tip and the sideways placed opening in one single operation. Conventional pencil point cannulas require at least two production steps, thus automated production is more complicated.

3. Development Stage
The patented method exists as a prototype.
4. Market / Opportunity
Spinal anaesthesia is commonly used prior surgical procedures like caesarean section, and knee and hip operations, In Germany it is estimated that 3.5 million spinal anaesthesia procedures are exe-cuted each year (3500 hospitals x 1000 procedures/hospital/year) and each procedure requires one cannula á 8€, which gives a national market worth 28 M€. The market for cannulas used for spinal anaesthesia in Germany, France, Great Britain and the US might be as high as 500 M€. The new cannula can through its innovative geometry provide a higher patient compliance compared to conventional pencil point or open cannulas, and thereby the demand from healthcare providers is expected to be high. Through the patented production method the manufacturing costs can be kept at a minimum and the margins still be hold on a high level.

The patent could be interesting for any company active in the area of medical devices and/or an IP-company that could grant license to a number of potential licensees, resp. enforce licenses in cases of unlawful breach of the patent.

Im Focus: Researchers Discover New Anti-Cancer Protein

An international team of researchers has discovered a new anti-cancer protein. The protein, called LHPP, prevents the uncontrolled proliferation of cancer cells in the liver. The researchers led by Prof. Michael N. Hall from the Biozentrum, University of Basel, report in “Nature” that LHPP can also serve as a biomarker for the diagnosis and prognosis of liver cancer.

The incidence of liver cancer, also known as hepatocellular carcinoma, is steadily increasing. In the last twenty years, the number of cases has almost doubled...

Im Focus: Researchers at Fraunhofer monitor re-entry of Chinese space station Tiangong-1

In just a few weeks from now, the Chinese space station Tiangong-1 will re-enter the Earth's atmosphere where it will to a large extent burn up. It is possible that some debris will reach the Earth's surface. Tiangong-1 is orbiting the Earth uncontrolled at a speed of approx. 29,000 km/h.Currently the prognosis relating to the time of impact currently lies within a window of several days. The scientists at Fraunhofer FHR have already been monitoring Tiangong-1 for a number of weeks with their TIRA system, one of the most powerful space observation radars in the world, with a view to supporting the German Space Situational Awareness Center and the ESA with their re-entry forecasts.

Following the loss of radio contact with Tiangong-1 in 2016 and due to the low orbital height, it is now inevitable that the Chinese space station will...

Im Focus: Alliance „OLED Licht Forum“ – Key partner for OLED lighting solutions

Fraunhofer Institute for Organic Electronics, Electron Beam and Plasma Technology FEP, provider of research and development services for OLED lighting solutions, announces the founding of the “OLED Licht Forum” and presents latest OLED design and lighting solutions during light+building, from March 18th – 23rd, 2018 in Frankfurt a.M./Germany, at booth no.

Im Focus: Tiny implants for cells are functional in vivo

For the first time, an interdisciplinary team from the University of Basel has succeeded in integrating artificial organelles into the cells of live zebrafish embryos. This innovative approach using artificial organelles as cellular implants offers new potential in treating a range of diseases, as the authors report in an article published in Nature Communications.

In the cells of higher organisms, organelles such as the nucleus or mitochondria perform a range of complex functions necessary for life. In the networks of...
