Catheter placement device including guidewire and catheter control elements
First Claim
1. A method for inserting a catheter into a patient, comprising:
- obtaining a catheter insertion tool, comprising;
a housing;
a needle distally extending from the housing, the catheter pre-disposed over the needle; and
a guidewire having a distal end pre-disposed in a lumen of the needle,the catheter including;
a catheter hub pre-disposed in the housing;
a catheter tube extending from the catheter hub, the catheter tube including a first material from a proximal end to a distal tip; and
a reinforcement component included in the distal tip of the catheter tube, the reinforcement component including a second material more rigid than the first material;
grasping the catheter insertion tool with a first hand;
inserting a distal end of the needle into the patient; and
using the first hand to;
advance the guidewire out of a distal opening of the needle utilizing a guidewire advancement assembly; and
move the catheter over the needle utilizing a catheter advancement assembly including a proximal portion in locking engagement with the housing when the guidewire advancement assembly is in a guidewire retracted position, wherein using the first hand to advance the guidewire comprises advancing the guidewire advancement assembly to a guidewire advanced position to disengage the proximal portion of the catheter advancement assembly from the housing.

Abstract
An insertion tool for inserting a catheter into a patient'"'"'s body is disclosed. The insertion tool unifies needle insertion, guidewire advancement, and catheter insertion in a single device. In one embodiment, the insertion tool comprises a housing in which at least a portion of the catheter is initially disposed, a hollow needle distally extending from the housing with at least a portion of the catheter pre-disposed over the needle, and a guidewire pre-disposed within the needle. A guidewire advancement assembly is also included for selectively advancing the guidewire distally past a distal end of the needle in preparation for distal advancement of the catheter. In one embodiment a catheter advancement assembly is also included for selectively advancing the catheter into the patient. Each advancement assembly can include a slide or other actuator that enables a user to selectively advance the desired component. Guidewire and catheter locking systems are also disclosed.

17. A method for inserting a catheter into a patient, comprising:
-
obtaining a catheter insertion tool, comprising; a housing including; a top housing portion; a bottom housing portion; and a stability structure having a top portion included with the top housing portion and a bottom portion included with the bottom housing portion, wherein the bottom portion of the stability structure includes a first arm designed to spread apart from a second arm to enable the catheter to pass out of the housing; a needle distally extending from the housing, the catheter pre-disposed over the needle; and a guidewire having a distal end pre-disposed in a lumen of the needle, the catheter including; a catheter hub pre-disposed in the housing; a catheter tube extending from the catheter hub, the catheter tube including a first material from a proximal end to a distal tip; and a reinforcement component included in the distal tip of the catheter tube, the reinforcement component including a second material more rigid than the first material; grasping the catheter insertion tool with a first hand; inserting a distal end of the needle into the patient; and using the first hand to; advance the guidewire out of a distal opening of the needle; and move the catheter over the needle utilizing a catheter advancement assembly including at least one wing extending laterally from the housing between the top portion and the bottom portion in a catheter insertion tool first position by moving the at least one wing in a distal direction with respect to the housing, thereby causing the first arm of the bottom portion of the stability structure to spread apart from the second arm. - View Dependent Claims (18, 19, 20)
