Abstract: A surgical apparatus includes a hub, a closure valve, an internal seal member, and a spring. The hub defines an internal chamber. The closure valve is disposed within the internal chamber and defines an internal bore extending therethrough. The closure valve is movable relative to the hub between a first position, substantially sealing the internal chamber, and a second position, establishing a fluid passage extending completely through the hub. The internal seal member is disposed within the internal bore of the closure valve and is movable relative to the closure valve between a closed position, substantially sealing the internal bore, and an open position, establishing an internal passage, different from the fluid passage, extending completely through the closure valve. The spring is disposed within the internal chamber and is configured to bias the internal seal member towards the closed position, thereby biasing the closure valve towards the first position.

Abstract: A surgical fluid transfer apparatus for passage of fluids includes a hub defining a longitudinal axis and having an internal chamber, an elongated member extending from the hub and a closure valve disposed within the internal chamber. The closure valve is adapted for movement between a first position substantially sealing the internal chamber to prevent passage of fluids and a second position establishing a fluid passage within the hub to permit passage of fluids therethrough. The closure valve includes a valve housing and a seal member. The seal member has an open condition establishing an internal passage different than the fluid passage to permit passage of an access instrument through the closure valve and a closed condition in the absence of the access instrument. The inner wall portions of the valve housing cooperate with the seal member to permit the seal member to assume the closed condition thereof.

Abstract: A surgical fluid transfer apparatus for passage of fluids includes a hub defining a longitudinal axis and having an internal chamber, an elongated member extending from the hub and defining a longitudinal conduit and a closure valve disposed within the internal chamber of the hub. The closure valve is adapted for movement between a first position substantially sealing the internal chamber to prevent passage of fluids and a second position establishing a fluid passage within the hub to permit passage of fluids therethrough. The closure valve includes a valve housing having inner wall portions defining a general tapered internal bore and a seal member at least partially disposed within the tapered internal bore of the valve housing. The seal member defines a general tapered configuration and has an open condition permitting passage of an access instrument through the closure valve and into the longitudinal conduit of the elongated member and a closed condition in the absence of the access instrument.

Abstract: Featured is a medical infusion device for vascular access with enhanced flashback visualization that includes a hub assembly having a flashback chamber. The hub assembly includes a proximal portion, a distal portion and a substantially transparent window section intermediate the proximal portion and distal portion. A needle is coupled to the flashback chamber so that fluid flows through the lumen of the needle into the flashback chamber after the needle is inserted into a blood vessel. A contrasting member is disposed on at least a portion of the hub assembly, so that when blood enters the flashback chamber, the contrasting member provides a high-contrast background when viewed through the window section.

Abstract: Featured is a vascular access device such as an IV catheter device including a housing, a tubular member, a seal member, a compression member, and a securing mechanism. The housing includes a proximal and distal portion and a chamber that extends between the proximal and distal housings. The tubular member is coupled to the housing distal portion so it is fluidly coupled to the chamber. The seal member is disposed within the chamber and the securing mechanism secures the seal member distal end to the housing proximal portion so the seal member is sealingly and compressibly retained between a chamber proximal end and the securing mechanism. Such a seal member also forms a septum, which is compressed by the compression member to prevent seepage upon removal of a stylet.
