New method for producing an innovative cannula used for spinal anaesthesia

16.12.2009
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: Temperature-controlled fiber-optic light source with liquid core

In a recent publication in the renowned journal Optica, scientists of Leibniz-Institute of Photonic Technology (Leibniz IPHT) in Jena showed that they can accurately control the optical properties of liquid-core fiber lasers and therefore their spectral band width by temperature and pressure tuning.

Already last year, the researchers provided experimental proof of a new dynamic of hybrid solitons– temporally and spectrally stationary light waves resulting...

Moving into its fourth decade, AchemAsia is setting out for new horizons: The International Expo and Innovation Forum for Sustainable Chemical Production will take place from 21-23 May 2019 in Shanghai, China. With an updated event profile, the eleventh edition focusses on topics that are especially relevant for the Chinese process industry, putting a strong emphasis on sustainability and innovation.

Founded in 1989 as a spin-off of ACHEMA to cater to the needs of China’s then developing industry, AchemAsia has since grown into a platform where the latest...

Im Focus: First real-time test of Li-Fi utilization for the industrial Internet of Things

The BMBF-funded OWICELLS project was successfully completed with a final presentation at the BMW plant in Munich. The presentation demonstrated a Li-Fi communication with a mobile robot, while the robot carried out usual production processes (welding, moving and testing parts) in a 5x5m² production cell. The robust, optical wireless transmission is based on spatial diversity; in other words, data is sent and received simultaneously by several LEDs and several photodiodes. The system can transmit data at more than 100 Mbit/s and five milliseconds latency.

Modern production technologies in the automobile industry must become more flexible in order to fulfil individual customer requirements.

Im Focus: Sharp images with flexible fibers

An international team of scientists has discovered a new way to transfer image information through multimodal fibers with almost no distortion - even if the fiber is bent. The results of the study, to which scientist from the Leibniz-Institute of Photonic Technology Jena (Leibniz IPHT) contributed, were published on 6thJune in the highly-cited journal Physical Review Letters.

Endoscopes allow doctors to see into a patient’s body like through a keyhole. Typically, the images are transmitted via a bundle of several hundreds of optical...
