1. A needle holder comprising:
an elongate stiff member having a proximal end, a distal end, and a longitudinal axis; a connector coupled to the distal end of the elongate stiff member, wherein the connector is capable of connecting to a needle; a guidewire holder coupled to the elongate stiff member proximally of the distal end, the guidewire holder comprising:
(a) a flexible locking element located proximally of the distal end of the elongate stiff member; and(b) a sliding knob arranged to slide over the flexible locking element in a direction parallel to the longitudinal axis and force the flexible locking element in a radial direction; and a lumen traversing the connector, the elongate stiff member, and the guidewire holder, wherein the lumen comprises an inner wall and an opening disposed proximally of the flexible locking element, wherein the lumen is configured to have a guidewire pass therethrough, whereupon sliding the sliding knob over the flexible locking element, the flexible locking element directly contacts and presses the guidewire against the inner wall and holds the guidewire in place. |
