System and Method for Inserting a Catheter

摘要

The invention provides methods and systems for introducing a catheter into a blood vessel. A catheter set comprising a pre-loaded stylet in a catheter is connectable to a guidewire. The guidewire may be introduced into the patient through a hollow needle. The stylet can then be connected to the guidewire, and the catheter advanced over the stylet and the guidewire into the access site and into position in the blood vessel of the patient. The invention reduces the time and placement steps required to position a catheter in a vessel and lowers the associated procedural costs. The invention reduces the frequency and severity of complications generally associated with introducing a catheter, thereby improving patient outcomes and lowering healthcare costs.

主权项

1. A method for introducing a catheter into a blood vessel, the method comprising:
inserting a hollow needle into a blood vessel; feeding a guidewire through the needle, the guidewire having a proximal end and a distal end; removing the needle from the blood vessel; providing a catheter set comprising:
a catheter having a proximal end and a distal end and defining a lumen; anda stylet having a proximal end and a distal end, wherein the stylet is disposed within the catheter lumen, and wherein the distal end of the stylet extends out of the distal end of the catheter; connecting the distal end of the stylet to the proximal end of the guidewire to create a stylet-guidewire complex; advancing the catheter into the vessel over the stylet-guidewire complex; and withdrawing the stylet-guidewire complex.
