    摘要： A catheter and introducer needle assembly with a needle shield is provided. The needle shield includes a means for preventing unwanted distal movement of the needle once the needle has been withdrawn into the needle shield. The needle shield also includes a means for connecting the needle shield to the catheter hub until the sharp distal tip of the introducer needle has been withdrawn into the needle shield. Thus, when the distal end of the introducer needle extends from the distal portion of the needle shield, the needle shield is connected to the catheter hub and when the sharp distal end of the introducer needle is withdrawn into the needle shield, the needle shield is disconnected from the catheter hub. At that point, the sharp needle tip is secured within the needle shield.

    摘要： A catheter assembly is disclosed having wings extending from the catheter adapter wherein each of the wings includes a stiffening member located therein. Each of the stiffening members may also define a means for maintaining the position of the stiffening members during the molding process to ensure that the stiffening member is properly located in the wing.

    摘要： The assembly of this invention comprises an elastic plug that is retained in a medical device, such as a catheter. A needle having a distal portion and a proximal portion resides in the elastic plug. The proximal portion has a different cross-section than the distal portion. In one embodiment, the cross-section of the proximal portion is smaller than the distal portion. Upon removal of the needle from the catheter and the elastic plug, the space in the elastic plug that had been occupied by the proximal portion of the needle is closed to effectively achieve the sealing function of the plug. The needle may include one or more notches in fluid communication with the needle lumen. One notch is preferably located at the juncture between the proximal portion and the distal portion of the needle to facilitate the blood flow between the needle and the catheter for better visualization of blood flashback by the clinician.

    摘要： A specific configuration for an over the needle catheter having a tapered outer wall and an angled introducer tip is disclosed. The catheter is molded of polyurethane material which is treated with a surface lubricant to ease the over the needle introduction of the catheter after venipuncture. The polyurethane material permits a minimal wall thickness for maximum flow with requisite strength and flexibility characteristics.
