Abstract: A device for one-handed insertion of a hollow needle and a guidewire includes a grip, an actuator carriage, a wire guide feed mount, a wire feed surface, and a plunger with a guidewire passage colinear with the needle. The actuator carriage has a trigger and is coupled with the plunger. The wire guide feed mount is mounted on the actuator carriage and has a guide fitting that couples with the plunger and directs the guidewire through the plunger. When the grip is engaged by one hand, a digit of the hand can advance the guidewire through the plunger by engaging the guidewire between the digit and the wire feed surface, sensing a degree of resistance encountered by a tip of the guidewire, with another digit of the hand urging the trigger and drawing the plunger rearwardly and/or forwardly, while the hand continues to engage the grip.

Abstract: A device for one-handed insertion of a hollow needle and a guidewire, includes a grip, a hollow needle, an actuator carriage, a plunger with a guidewire passage through said plunger, the actuator carriage having a trigger, the actuator being coupled with the plunger wherein the plunger is disposed such that the guidewire passage is co-linear with said hollow needle. A wire guide feed mount is mounted on said actuator carriage and has a guide fitting adapted to couple with said plunger and direct the guidewire into the guidewire passage through the plunger. The device further includes a wire feed surface.

Abstract: A device for one-handed insertion of a guidewire into a vessel or cavity is provided. The device has a body, an actuator carriage, a guidewire feed, and a syringe. The body has a handle, a guideway, and a clip to retain the syringe. The syringe has a barrel and a plunger with a flange and a guidewire passage. The actuator carriage has a trigger and a clip to grasp the syringe plunger flange. The actuator carriage slides along the body guideway. The guidewire feed has a wire feed surface. The thumb engages wire at the wire feed surface to advance and retract the wire through the guidewire passage and a finger moves the trigger to move the syringe plunger rearwardly and/or forwardly, while the remaining fingers of the one hand grasp the handle. The device allows the user to sense resistance encountered by the tip of the wire.
