A stimulating needle and catheter system, including components, is provided such that the position of the stimulating needle or the stimulating catheter may be identified after insertion into the body of a patient by electrically stimulating and thus locating a specific nerve. Use of the needle and catheter system is eased by providing the system to the medical practitioner in a unitary structure. That is, the needle and catheter are connected by a catheter lock. The catheter lock is attached to the hub of the needle and can be actuated to either firmly grip the catheter or allow the catheter to move axially with respect to the lock and needle assembly. Thus, supplying the catheter to the practitioner already locked into the catheter lock allows the practitioner to insert the needle into the patient and, when ready, release the catheter for disposal through the needle into the patient. This and other disclosed features allow the medical practitioner to focus attention on the medical procedure.

L'invention porte sur un système aiguille et cathéter de stimulation comprenant des composants et conçu de sorte que la position de l'aiguille ou du cathéter de stimulation puisse être identifiée après leur introduction dans le corps d'un patient, par stimulation électrique, ce qui permet de localiser un nerf spécifique. Le système aiguille et cathéter est présenté au médecin sous forme d'une structure unitaire de façon à faciliter son utilisation. A savoir que l'aiguille et le cathéter sont raccordés par un élément de blocage du cathéter. L'élément de blocage est relié au pavillon de l'aiguille et peut-être activé pour saisir fermement le cathéter ou permettre au cathéter de se déplacer axialement par rapport à l'ensemble élément de blocage et aiguille. Ainsi, en fournissant un cathéter déjà bloqué dans l'élément de blocage, ceci permet au médecin d'introduire l'aiguille dans corps du patient et, au moment voulu, de se débarrasser du cathéter par l'intermédiaire de l'aiguille introduite dans le corps du patient. Ce système permet au médecin de focaliser son attention sur l'intervention chirurgicale.
