Abstract: A multi-component sealant applicator comprises a dual catheter for delivering sealant. Each catheter communicates with one of a pair of fluid sealant agent sources and comprises a mixing volume within the dual catheter for mixing multiple components of a multi-component sealant prior to discharge from a distal end of the catheter and a clearing system to clear undesired material from the mixing volume or the vicinity of the mixing volume, wherein one catheter is mounted for longitudinal movement within the other and the inner catheter is usable as a plunger to remove clogs. The catheter may comprise a reciprocal drive mechanism proximally coupled with the dual catheter to move one catheter longitudinally with respect to the other. The drive mechanism may comprise a ratchet and pawl.

Abstract: A blood collection device includes a needle hub with a flashback chamber and a vent plug covering the flashback chamber. The vent plug permits a flow of air across the vent plug but prevents a flow of liquid across the vent plug. An intravenous cannula is mounted to the hub and extends into the flashback chamber. A non-patient cannula is mounted to the hub and also extends into communication with the flashback chamber. A passive shielding device is mounted to the hub and can be moved from a proximal position where the intravenous cannula is exposed to a distal position where the intravenous cannula is partly shielded. The flashback chamber can be observed to provide an early indication of venous access. A fluid collection tube then can be placed in communication with the non-patient needle and can simultaneously trigger movement of the safety shield.

Abstract: Devices and methods are disclosed for achieving chest drainage in humans or other animals. Chest drainage is often required following traumatic injury or surgery. The devices and methods disclosed herein are especially useful in the emergency, trauma surgery or military setting. The devices utilize a chest tube with a cutting distal end and a central blunt trocar. The blunt trocar or obturator shields the sharp cutting distal end of the chest tube until controllably retracted. Once the blunt trocar or obturator is retracted, the chest tube is advanced out through its sterile, protective package and into the patient. The blunt trocar is advanced back into its position to shield the sharp tip of the chest tube during patient insertion. The chest tube also includes a hold-down mechanism that is created by an adhesive seal to the patient's chest and ribbons or straps that are wrapped around the chest tube once it is correctly positioned.

Abstract: An elongated, rigid cannula has a peripheral wall defining a central bore and a side port for introduction of material into the bore. A covering of resilient, flexible material is provided in the area of the side port, with a corresponding aperture aligned with the port of the cannula. The aperture of the resilient covering can be somewhat smaller than the underlying cannula port, forming a resilient margin that overhangs and surrounds the port.

Abstract: A catheter includes a tube formed of plastic, a helical spring coil formed of metal and a ribbon which is longitudinally substantially non-extendable. The coil is coaxially disposed within the tube and substantially coextensive longitudinally with the tube. The ribbon is disposed within the coil, proximal ends of the ribbon and the coil being secured together, and the ribbon distal end being secured to the coil body at a predetermined point of the coil body adjacent but substantially proximally spaced from the coil distal end. The ribbon precludes substantial longitudinal extension of the coil body intermediate the coil proximal end and the predetermined point, thereby to limit longitudinal extension and increase the pull strength of the catheter.
