摘要： A device and method for dispensing a liquid with a gas includes an instrument having a cannula and a low-pressure tip. The low-pressure tip includes a tip housing that at least partially defines a high pressure chamber. A distal wall of the tip housing includes an aperture in fluid communication with the high pressure chamber. The low-pressure tip also includes a tube and a gas flow channel. The tube fluidly communicates liquid at a relatively low pressure from the cannula through the first aperture. The gas flow channel fluidly communicates gas from the cannula at a relatively high pressure and to the high pressure chamber for discharge from the aperture. The tube and aperture are adapted to dispense the liquid and the gas in order to create a low pressure zone distal of the tube to dispense droplets of the liquid.

摘要： An instrument for delivery, deployment, and tamponade of a hemostat. A delivery cannula is included and has a proximal end, a distal end, and a lumen therebetween. A shaft is configured to be introduced into and move relative to the lumen. A hemostat applicator at the distal end of the shaft includes a tamponade surface. The applicator is configured to transition between a first, compact state for introduction into and movement within the lumen, and a second, expanded state as the applicator exits from the delivery cannula.

摘要： A gas-assisted fluid-dispensing device configured to deliver an aerosol onto a surgical site. The fluid-dispensing device includes at least one fluid chamber configured to contain a fluid. The fluid chamber has a distal end and proximal end. A plunger extends at least partially into the fluid chamber from the proximal end. A spray nozzle tip is fluidly coupled to the distal end of the fluid chamber and is coupled to a gas supply. The tip is capable of generating aerosol with a gas from the gas supply and the fluid from the fluid chamber. A housing has an upper portion with a docking port configured to operably receive the fluid chamber. An actuating member is operably coupled to a plunger and is configured to apply a force to the plunger to discharge fluid from the fluid chamber and into the tip.

摘要： A device and method for removing gas from a mixture of biomaterials includes a vacuum pump movably positioned within a cavity of a syringe at least partially defining a vacuum chamber. The vacuum pump has a pump body with proximal and distal portions, a stopper connected to the distal portion, and a flow channel. The stopper includes an inlet, and the pump body includes a port. The flow channel extends from the inlet to the port and is in fluid communication with the vacuum chamber. A first valve is positioned within the flow channel between the inlet and the port.
