Abstract: Valve assemblies having improved ability to selectively control flow of fluids through the catheter and prevent leakage of fluids from the proximal end of a catheter that is positioned within a patient. Such improved catheter valve assemblies also prevent leakage of fluids after repeated insertion and removal of medical instruments through the valve.

Abstract: Methods and devices to facilitate positioning of a catheter into a vessel. Devices include axially concentric assemblies of a piercing cannula, a shield and tubing such as a catheter where the shield can be passively or actively locked into position over the cannula tip to prevent inadvertent needle sticks.

Abstract: The invention relates to a blocking mechanism for a skin incision device and to a method of controlling of a skin incision device by a blocking mechanism. The blocking mechanism comprises a blocking means and a trigger means, which by, respectively, a fixing means and a locating means are mounted in a housing of the cooperating incision device, and which are provided with an engaging means configured to cooperate mutually with each other so that an inadvertent firing of the blocking mechanism and an inadvertent actuation of the incision device prior to use of the device as well as a re-use of the device is not possible, and an indication of a state of use of the device by the blocking means and the trigger means is unambiguous.

Abstract: The invention relates to a safety needle device, for a medical instrument, to insert a needle into a patient's body to a determined insertion depth. The safety needle device, in two variants with a fixed insertion depth and with an insertion depth adjustment, comprises a hub, a needle, a protecting shield, longitudinal resilient means, transverse resilient means, a housing, and is provided with different technical means configured to cooperate with each other in order to perform different functions of the device. The safety needle device enables to control a state of use of the device, wherein the device is a disposable one and it ensures its user a protection against an accidental or intentional prick of the needle before and after the due use of the device for the purpose for which it is intended.
