The present invention discloses a pressure depending clutching device capable of automatically engaging and disengaging a needle from a driving force depending on the pressure experienced by needle. The device has a body with an interior space a pressure sensing element disposed in the body defining a portion of a pressure chamber and a force receiving element operatively connected to the pressure sensing element. The force receiving element has a shape complimentary to a portion of a force sending element operatively connected to a force applying structure. The pressure sensing element the force receiving element and the complementary force sending element form a driving force engaging mechanism for coupling the force applying structure to the needle during operation. Also provided are needle and syringe assemblies incorporating the disclosed clutching devices methods for manufacturing the disclosed clutching devices as well as methods for safely locating and positioning needles in the body cavity utilizing a needle and syringe assembly incorporating the disclosed clutching devices.
