Progressive Suppleness Pursil Catheter: a new tool for superselective angiography and embolization.

Over the past few years, major advances in the development of new microcatheter systems have greatly improved the safety and efficacy of therapeutic endovascular techniques [1 -4]. The ideal embolization catheter should have the following characteristics: simplicity of use, ability to negotiate tortuous curves with a minimum of manipulations and without trauma to the artery or induction of spasm, outer diameter small enough that the physical presence of the catheter in the vessel is not occlusive, and inner diameter large enough to permit a choice of embolic agents of various types and sizes. We present our experience with the Progressive Suppleness Pursil Catheter,* which helps fulfill these criteria.
