US Patent 11925779 Catheter insertion device including top-mounted advancement components

An insertion tool for inserting a catheter into a patient's body includes a housing in which at least a portion of the catheter is initially disposed, a hollow needle distally extending from the housing with the catheter pre-disposed over the needle, and a guidewire pre-disposed in the needle. The insertion tool can include a guidewire advancement assembly that can include a first finger pad for selectively advancing the guidewire distally past a distal end of the needle in preparation for distal advancement of the catheter. The insertion tool can further include a catheter advancement assembly that can include a second finger pad for selectively advancing the catheter into the patient. The first and second finger pads can be positioned such that a user can begin to advance the second finger pad after advancing the first finger pad without substantially re-positioning the thumb or finger of the user.
