Intrathecal chronic catheterization in the rat.
This article describes the fixing of intrathecal cannula to the processus transversus T1. This method of fixing prevents rejection and allows the use of chronic cannula for experiments on animals over long periods up to one year. The intrathecal implantation may be made caudally from T1 using cannula from 1 to 7.5 cm. The technique for repeated perfusion in the freely behaving rat is described.
