CA 2411943

The present invention is an alignment system by which a needle or other similar invasive device can be positioned for insertion so as to have a real- time, predetermined trajectory to a targeted tissue region, thereby reducing the need for repetitive needle insertion and withdrawal to move the tip of the instrument accurately to the target site. The insertion device (20) comprises a needle (26) having a proximate puncture end (22), an energy source housing (28) located at the distal end (24), and a viewing surface or hub (32) located on the housing (28).

L'invention porte sur un système d'alignement permettant de positionner une aiguille ou un dispositif invasif similaire en vue de son introduction en temps réel selon une trajectoire prédéterminée vers une zone cible des tissus, ce qui évite de réitérer les introduction et retraits de l'aiguille pour placer l'instrument avec précision sur le site cible. Le système d'introduction (20) comporte: une aiguille (26) présentant une extrémité proximale (22) de perforation, un boîtier (28) contenant une source d'énergie placé à l'extrémité distale (24), et une surface de visualisation (32) ou moyeu placé sur le boîtier (28).
