ABSTRACT:
A catheter insertion device (10) is disclosed which is usable to insert a very flexible catheter (12) formed of a silicone elastomer into the blood vessel of a patient. Catheters of highly flexible material, such as silicone elastomer, are highly desirable for use as such catheters in that they do not initiate a build-up of fibrin in the blood stream as do other, more rigid, catheters. A hub member (18) is slidably received over a needle (14) carrying the catheter (12) and a semi-rigid sleeve (26) extends under the proximal end of the catheter (12) so as to aid in removing the catheter (12) from the needle (14) after the needle (14) has been inserted into the blood stream of the patient.
