Device for the injection of drugs into microvessels

A catheter and a catheter system for the injection of drugs in a microvessel, in particular in a retinal microvessel is provided, wherein the catheter compromises a single piece tubing (1) made of quartz glass, the tubing having an end portion (2) having a sharp tip (3), the end portion tapering towards said sharp tip (3). The catheter is mounted to a sleeve (5) which is mounted to the tip (6) of an endoscope.

Method and apparatus for producing glass bodies by means of redrawing methods

In redrawing methods a kind of rod or raw blank glass is heated and drawn in a malleable shape to a glass body with requested end profile. The advantages of redrawing methods are the possibilities to produce profitably smaller quantities of glass bodies and to organize a flexible production.
