An apparatus for controlling deposition of material from a plasma transferred wire arc (PTWA) torch within a bore is provided. The apparatus includes a duct and a plurality of cannons. The duct includes a plurality of fluid passageways separated by cross-members. The plurality of cannons are disposed adjacent and downstream from the plurality of fluid passageways of the duct. The flow of fluid is simultaneously directed through all of the fluid passageways and the plurality of cannons and past the PTWA torch in the bore.

A free radical sterilization system having a chamber defining a region, and a generator for generating free radical reach effluent from a free radical electric generator and/or a vaporizer. A closed loop circulating system without a free-radical destroyer is provided for supplying the mixture of free radicals from the electric generator mixed with the hydrogen peroxide solution in the form of the effluent to the chamber. The free-radical sterilization system is used in sterilizing items in the chamber and, with an open-bottomed wound chamber, in treating wounds on a body.

A thermal spray apparatus to apply coatings to external and internal surfaces in restricted areas is provided. The apparatus includes: a fuel input line; an oxidizing gas input line; coolant input and outlet; a combustion chamber that facilitates primary combustion; a diverging section that splits the primary combustion flow into two or more streams; an elbow section that redirects the combustion streams; a convergent/divergent nozzle; a convergence section that recombines the combustion streams into a single combustion stream within an injection zone of the convergent/divergent nozzle; and a feedstock injector for the injection of feedstock material for forming said coatings into said injection zone of the convergent/divergent nozzle; wherein the convergent/divergent nozzle has a nozzle throat downstream of the injection zone whereby in operation the injection pressure of the feedstock material upstream of the nozzle throat approximates the pressure of the combustion stream within the injection zone. The apparatus may also include the use of an accelerating gas.

A cartridge device is provided for applying a fiber matrix to a tubular member such as a saphenous vein graft. The cartridge includes a housing, a tubular member holder, a rotational drive, and a polymer delivery assembly. The housing defines a chamber which surrounds the tubular member holder. The rotational drive rotates the tubular member during the fiber application process.

A surgical spray instrument is disclosed comprising a main body connectable to a transfer tube; a propellant actuator for selectively releasing propellant from the main body and along the transfer tube and out through a distal end thereof. An ion emitter is arranged along the tube, the ion emitter having an ion emission zone. This enables the directed and concentrated delivery of therapeutic, pharmacological and diagnostic agents to tissues inside or outside of the body. There is further disclosed a surgical assembly for enabling uniform deposition of a particulate material to a surface of an intracorporeal cavity of a patient. The surgical assembly comprises an ion emitter; a dispenser having an outlet locatable within the cavity and for dispensing the particulate material therefrom, and a processor for determining a location of the ion emission zone of the ion emitter in dependence upon the position of the outlet of the distributor within the cavity to provide for the uniform deposition.

A system for use in maintaining a pipe includes a motorized apparatus including a body assembly and at least one maintenance device. The at least one maintenance device includes a sprayer, a heater, and an infrared sensor. The system includes at least one controller configured to apply the at least one coating material to the interior surface of the pipe at a work location using the sprayer, heat the interior surface of the pipe at the work location using the heater to begin a cure of the at least one coating material, generate one or more infrared images of the work location using the infrared sensor while using the heater to cure the at least one coating material, and perform a non-destructive evaluation (NDE) of the work location based on the one or more infrared images.
