Kurzfassung

A German university has developed a reliable, safe and easy-to-use system for introducing devices into the vessels of human or animal bodies. The peel-away sheath introducer set with an integrated sealing system minimizes the risk of bleeding and vessel wall trauma. The University seeks industrial partners for research collaboration with licensing option and/or commercialization of the technology.

Details

The introduction of a device (e.g. a catheter) into a vessel of a human or animal body in order to accomplish a medical procedure is related to some fundamental problems. The device must be inserted through a puncture site in the vessel wall into the lumen of the vessel. This causes bleeding and possibly wall trauma.

Currently, sheath introducers and hemostatic agents (agents causing the bleeding process to stop) are used to minimize these risks. However, these approaches have not been able to fully solve the problems. There is still a need for a reliable, safe and easy-to-use device.

A German University has developed a catheter introducing system which prevents bleeding and minimizes wall trauma, thus overcoming the limitations of the conventional methods. 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 coaxially 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 way. 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 the 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.

Innovative Aspects:
- Safe, easy-to-use and minimally invasive introducing procedure;
- Reduced bleeding during the intervention;
- Minimal risk of wall trauma;
- Effective sealing after removal of the access cannula.
