This invention is an apparatus and method for delivering a treating element (22), such as a radiation source, through a catheter (60) to a desired site in avascular system of a patient, such as a coronary artery, for inhibiting the formation of scar tissue such as may occur in restenosis following balloon angioplasty. The apparatus includes an elongate flexible catheter tube (20) having proximal and distal portions, with a lumen (202) extending therebetween, and a diameter sufficiently small for insertion into the patient's vascular system. One or moretreating elements (22), such as a capsule or pellet containing radioactive material, is positionable within the lumen and movable between the proximal and distal endportions under the force of a liquid flowing through the lumen. A method for using such apparatus, including a method for using such apparatus simultaneously with a balloon angioplasty procedure, is disclosed.

Appareil et méthode permettant de livrer, au moyen d'un cathéter (60), un élément thérapeutique (22), comme une source de rayonnement, jusqu'à un site précis du système vasculaire d'un patient, comme une artère coronaire, en vue d'inhiber la formation de tissus cicatriciels comme peut en produire une resténose suivant une angioplastie à ballonnet. L'appareil comprend un cathéter souple allongé (20) comptant une portion proximale et une autre distale, entre lesquelles passe une lumière (202), d'un diamètre assez petit pour permettre de l'insérer dans le système vasculaire du patient. Un ou plusieurs éléments thérapeutiques (22), comme une capsule ou une pastille contenant un matériau radioactif, peuvent ainsi être placés dans la lumière et se déplacer sous la pression d'un liquide entre les extrémités proximales et distales. Une méthode permettant d'utiliser cet appareil simultanément à l'angioplastie est décrite.
