CA 2599938

Methods of manufacturing a catheter introducer or needle assembly and needle shield are disclosed. A needle shield has a blocking object (preferably a ball) which moves from an non- shielding position to a shielding position. The catheter introducer is made by placing the blocking object into the shield and inserting the proximal end of the needle into the shield while the blocking object is in the shielding position. The catheter introducer is made using extruded polymeric tubes which may have coextruded reinforcing.

La présente invention concerne des procédés de fabrication d~un élément d~introduction de cathéter ou ensemble d~aiguille et dispositif de protection d~aiguille. Un dispositif de protection d~aiguille possède un objet de blocage (de préférence une bille) qui se déplace d~une position de non-protection à une position de protection. L~élément d~introduction de cathéter est réalisé en plaçant l~objet de blocage dans le dispositif de protection et en insérant l~extrémité proximale de l~aiguille dans le dispositif de protection alors que l~objet de blocage est dans la position de protection. L~élément d~introduction de cathéter est réalisé à l~aide de tubes polymères extrudés qui peuvent avoir un renforcement coextrudé.
