Catheter placement device including guidewire and catheter control elements
First Claim
1. A method for inserting a catheter into a body of a patient, comprising:
- obtaining a catheter insertion tool, comprising;
a housing;
a needle having a proximal end attached to the housing and a tissue-penetrating distal end extending from the housing;
a guidewire initially disposed in the needle, the guidewire coupled to a guidewire advancement assembly; and
a catheter disposed over the needle with a proximal portion initially disposed in the housing, the catheter coupled to a catheter advancement assembly including;
a handle assembly removably attached to the catheter; and
a safety clip in a safety housing, the safety clip slidably disposed over the needle;
grasping the catheter insertion tool with a first hand;
inserting the tissue-penetrating distal end of the needle into the patient using the first hand;
advancing the guidewire out of a distal opening of the needle and into the patient via the guidewire advancement assembly without relocating the first hand;
moving the catheter over the needle and into the patient via the catheter advancement assembly without relocating the first hand by moving the handle assembly relative to the housing until the safety clip captures the tissue-penetrating distal end of the needle; and
detaching the catheter insertion tool from the catheter.

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.

11. A method for inserting a catheter into a blood vessel, comprising:
-
grasping a catheter insertion tool with a first hand, the catheter insertion tool including; a housing having a top portion attached to a bottom portion, the top portion including a distal slot, the bottom portion having a distal section extending through the distal slot; a needle having a proximal end attached to the housing and a tissue-penetrating distal end extending from the housing; a guidewire advancement assembly including a guidewire having a distal end disposed in a lumen of the needle in a catheter insertion tool first position; and a catheter advancement assembly including; a catheter disposed over the needle with a proximal portion disposed in the housing in the catheter insertion tool first position, at least one wing extending laterally from the housing between the top portion and the bottom portion in the catheter insertion tool first position, and a safety housing having a safety clip therein, the safety clip disposed over the needle; inserting the tissue-penetrating distal end of the needle into the blood vessel using the first hand; activating the guidewire advancement assembly without relocating the first hand to advance the distal end of the guidewire into the blood vessel; moving the catheter advancement assembly relative to the housing without relocating the first hand to advance the catheter over the needle and the distal end of the guidewire into the blood vessel until the safety clip captures the tissue-penetrating distal end of the needle; and removing the catheter advancement assembly from the catheter. - View Dependent Claims (12, 13, 14, 15, 16)
