Abstract

A needle system includes a needle, a needle handle coupled to a proximal end of the needle and a needle stiffening device. The needle stiffening device includes a first handle portion, a second handle portion, a stylet having a distal end component and a shaft component, a fixing component configured to fix a proximal end of the stylet to the first handle portion, a hollow component configured to slidably receive the shaft component of the stylet and a compression device having a proximal end that makes contact with a distal end of the hollow component and a distal end that makes contact with the distal end component of the stylet. A distal end of the second handle portion makes contact with a proximal end of the hollow component within the first handle portion.
