Abstract: Protective catheter devices are disclosed including a barrel for housing a catheter including a needle extending therefrom. The catheter is slidably retained within the barrel between a fully retracted position and an extended position, in which the needle can be inserted into a patient, and the device includes a locking mechanism for controlling the position of the needle within the barrel, which includes at least two positions; namely, a first position in which the needle is freely slidable within the barrel and a second position in which the needle is locked in its retracted position within the barrel, such that the needle cannot be displaced from its retracted position without repositioning the locking mechanism.

Abstract: A composite catheter assembly for fixing, locating, inserting and accurately securing intravenous catheters having a needle thereon within body fluid conduits has an attachment plate with an elongated opening therein, a barrel having a bore extending inwardly from one open end of the barrel to define a transverse shoulder so that a passage or sized opening can be provided between the bore and the exterior of the barrel at the transverse shoulder end of the bore, a catheter assembly including, a carrier is slidably mounted in the bore of the barrel for movement of the needle on the catheter assembly from a retracted position in the barrel to an extended position into the body fluid conduit, and a retracting assembly is provided which includes, a spring that is compressed when the catheter assembly is moved from the retracted position to the extended position, and an operatively associated locking and latching assembly to hold and releasably lock the catheter assembly in the extended position and when actuated

Abstract: A Composite Catheter Assembly for fixing, locating, inserting and accurately securing intravenous catheters having a needle thereon within body fluid conduits has an attachment plate with an elongated opening therein, a barrel member having a bore extending inwardly from one open end of the barrel to define a transverse shoulder so that a passage or sized opening can be provided between the bore and the exterior of the barrel at the transverse shoulder end of the bore, a catheter assembly is slidably mounted in the bore of the barrel member for movement of the needle on the catheter assembly from a retracted position in the barrel member to an extended position into the body fluid conduit, and a retracting assembly is provided which includes, a resilient member that is compressed when the catheter assembly is moved from the retracted position to the extended position, and an operatively associated locking and latching assembly to hold and releasably lock the catheter assembly in the extended position and when

Abstract: A device for securing catheters to grafts and the like implanted in patients, primarily for use in connection with dialysis treatments is disclosed, including an anchoring bracelet for attachment to the patient at a predetermined location at which the graft is located, a rotatable saddle rotatably mounted on the anchoring bracelet, in which the saddle includes an aperture adapted to receive the catheter, a contact surface having a shape adapted to mate with the graft, and a saddle channel extending between the aperture and the contact surface, and stabilizing tabs for preventing removal of the rotatable saddle from the anchoring bracelet so that the catheter can be accurately located in the graft and firmly anchored on the patient.

Abstract: A device for securing catheters to grafts and the like implanted in patients, primarily for use in connection with dialysis treatments is disclosed, including an anchoring bracelet for attachment to the patient at a predetermined location at which the graft is located, and an adjustable saddle adjustably mounted on the anchoring bracelet, in which the saddle includes an aperture adapted to receive the catheter, a contact surface having a shape adapted to mate with the graft, and a saddle channel extending between the aperture and the contact surface, so that the catheter projects a predetermined distance from the contact surface when it has been inserted into the aperture, thereby permitting the catheter to be accurately located in the graft and firmly anchored on the patient. Such catheter devices including a catheter with a needle portion and a tubular catheter conduit for delivery of or removal of body fluids to the catheter is also disclosed.
