    Abstract: A pressure relief mechanism is incorporated into a modified syringe-type inflation device that may be coupled to a balloon catheter for inflating and deflating the balloon. An engagement mechanism selectively engages and disengages from a threaded shaft for advancing or withdrawing a plunger placed in slidable, yet sealing fit within a cylindrical chamber. In a first engaging position, the threaded shaft may be forcibly advanced or withdrawn in the cylindrical chamber, while in a second disengaged position, the plunger may be quickly pulled back.

    Abstract: The present invention generally relates to a medical device and procedure for accurately positioning a catheter across a desired region within a patient's vasculature. In particular, the present invention provides a hub assembly unit that allows a physician to precisely position a stent within a vessel utilizing a stent delivery catheter. The hub assembly unit includes a fine adjustment mechanism. The fine adjustment mechanism extends or contracts the length of the hub assembly unit in controlled incremental units. These controlled fine displacements are then translated directly to the stent delivery or balloon dilation catheter.

    Abstract: A fluid injection system is disclosed The system is adapted to employ first and second injectors which may sequentially, or simultaneously, inject first and second fluids into a patient via a catheter. The first and second injectors may be power actuated. The actuation of the injectors may be controlled via a controller of the system. The user may be provided with an operator interface module to enable the control of the system to be affected during operation. A separate waste line may be provided to drain the system effectively and efficiently. A pressure sensor may be provided proximate the catheter to reduce pressure signal wave dampening and fluid waste.

    Abstract: Disclosed is a manifold including a housing having multiple ports and multiple bores networking the ports. An actuatable valve, such as a slidable valve, including one or more bores may be positioned in the housing such that the valve is actuatable between a first position and a second position. Actuation of the valve may selectively establish a desired fluid pathway through the manifold. One or more seals may be interposed between the valve and the housing. The seal includes at least a first sealing element, a second sealing element, and a land extending between the sealing elements. The sealing elements are configured to provide a fluid tight seal between the housing and the valve when the valve is in either the first or second position, and the land is configured to provide a fluid tight seal between the housing and the valve when the valve is in an intermediate position.
