Abstract: A device for facilitating positioning of a needle during a medical procedure may include a needle receiver configured for removable/reversible attachment of a proximal end of a needle; a stop set back from a distal end of the needle receiver and against which a needle received by the needle receiver abuts; and a trigger configured to move the needle receiver relative to the stop when activated by a user such that the stop forces detachment between the needle receiver and the needle. The device may monitor the pressure at the distal end of the needle as the needle is advanced and provide indication to a user when a predetermined pressure or pressure differential is reached.
