Catheter insertion device
First Claim
1. A catheter insertion device, comprising:
- a handle comprising a front face having an opening;
a needle cannula partially within the handle, the needle cannula comprising a sharp distal tip extending distally from the handle;
a guidewire partially within the handle and the needle cannula; and
a first actuator connected to the handle and the guidewire, the first actuator being movable relative to the handle to move the guidewire relative to the handle, and the opening in the front face of the handle configured to receive the first actuator, wherein;
moving the first actuator in a proximal direction relative to the handle causes a distal end of the guidewire to move in a distal direction away from the handle, andmoving the first actuator in the distal direction relative to the handle causes the distal end of the guidewire to move in the proximal direction towards the handle,such that moving the first actuator in a longitudinal direction for a distance causes the guidewire to move in an opposite longitudinal direction of the first actuator for the same distance.

Abstract
A catheter insertion device that allows for single-handed insertion of the catheter within the vasculature of the patient is disclosed. The catheter insertion device includes a handle, a needle cannula partially within the handle, a guidewire partially within the handle and the needle cannula, and a first actuator connected to the handle and the guidewire. The first actuator is movable in a proximal direction relative to the handle to cause the guidewire to move in a distal direction away from the handle, and is movable in a distal direction relative to the handle to cause the guidewire to move in a proximal direction towards the handle. The catheter insertion device can also include a needle support that stabilizes the needle cannula during insertion of the needle cannula into a patient.

26. A catheter insertion device, comprising:
-
a handle; a needle cannula partially within the handle, the needle cannula comprising a sharp distal tip extending distally from the handle; a guidewire partially within the handle and the needle cannula; a first actuator connected to the handle and the guidewire, the first actuator being movable relative to the handle to move the guidewire relative to the handle; and a needle support rotationally coupled to a region of the handle and configured to stabilize a portion of the needle cannula during insertion of the needle cannula into a patient, wherein moving the first actuator in a longitudinal direction for a distance causes the guidewire to move in an opposite direction for the same distance. - View Dependent Claims (27)
