Abstract
(EN)
Tissue access devices and methods of using and making the same are disclosed. The devices can have a needle, a housing having wings, a tube having a flow channel, a tube first extension, and a tube second extension, and a torsion spring having a first coil and a second coil. The first coil can have a first coil first arm and a first coil second arm. The first coil first arm can be shorter than the first coil second arm. The second coil can have a second coil first arm and a second coil second arm. The second coil first arm can be shorter than the second coil second arm. The devices can have a sensor. More energy can stored in the torsion spring when the sensor is in a sensor closed configuration than when the sensor is in a sensor open configuration.

L'invention concerne des dispositifs d'accès à des tissus biologiques et des méthodes d'utilisation et de fabrication de ceux-ci. Les dispositifs peuvent comporter une aiguille, un boîtier doté d'ailettes, un tube doté d'un canal d'écoulement, d'une première extension de tube et d'une seconde extension de tube, et un ressort de torsion doté d'une première bobine et d'une seconde bobine. La première bobine peut comporter un premier bras de bobine et un second bras de bobine. Le premier bras de bobine peut être plus court que le premier bras de bobine. La seconde bobine peut comporter un second bras de bobine et un second bras de bobine. Le second bras de bobine peut être plus court que le second bras de bobine. Les dispositifs peuvent comporter un capteur. Le ressort de torsion peut stocker plus d'énergie lorsque le capteur est dans une configuration fermée que lorsqu'il est dans une configuration ouverte.
