A laser strikes and aseptically heats or sterilizes the end of two flexible tube ends for connection. Tube holders are pushed toward each other to bring the tube ends into contact. A weld detector checks the characteristics of the weld. A laser optics assembly may be used to chance the direction of the lacer and focus the laser at the tube ends. In addition, a crimping device is used to compress a single flexible tube for disconnection. The laser strikes the compressed area. The crimping device continues to pinch the area and forms a seal in the tube. The tube is separated into two tube segments, each segment has a sealed end.

Apparatus and method for connecting and disconnecting flexible tubing

Flow-through systems for processing biological fluid are disclosed. The flow-through systems include a removal device in the flow path for removing unwanted compounds and agents. The removal device includes a removal media contained within a housing made of two separate portions sealed together. The housing is maintained in a substantially vertical disposition, thereby ensuring substantially uniform and complete exposure of the fluid to the media.

Flow-through removal device and system using such device

A laser strikes and aseptically heats or sterilizes the end of two flexible tube ends for connection. Tube holders are pushed toward each other to bring the tube ends into contact. A weld detector checks the characteristics of the weld. A laser optics assembly may be used to change the direction of the laser and focus the laser at the tube ends. In addition, a crimping device is used to compress a single flexible tube for disconnection. The laser strikes the compressed area. The crimping device continues to pinch the area and forms a seal in the tube. The tube is separated into two tube segments, each segment has a sealed end.

This invention provides a medical device for delivering volumetric quantities of a first and a second biochemically reactive fluid in which separate MBUs atomize the fluids. The device of the present invention includes a fluid delivery device for laparoscopically delivering fluids having two feed conduits for delivering fluid to feed ports of the mechanical breakup units, the mechanical breakup units having two feed ports for receiving fluid from the feed conduits and directing such fluid into spin chambers and funneling portions having a sloped sidewall for directing fluid from the spin chambers through an exit port. The device is suitably dimensioned for creating a spray of two fluids with different viscosities such as fibrinogen and thrombin in such a manner that the thrombin spray cone encompasses the fibrinogen spray cone at a distance of about one inch from the exit port with a 0.5 cc/second flow rate to avoid depositing unreacted fibrinogen on a surface. Other instruments such as optical fibers may be incorporated within the device.

Mechanical breakup unit for biochemically reactive fluid delivery device

A vacuum demand valve for delivering a flowable material is disclosed. The valve has a housing having a proximal end, a distal end, an intermediate segment therebetween defining a passageway wherein the flowable substance can flow from the proximal end to the distal end. The housing can be a tubing. A valve member is located along the intermediate segment. The valve member has a closed condition wherein the flow of the flowable material from the proximal end to the distal end is stopped and an open condition wherein the flow of the flowable material from the proximal end to the distal end is unstopped. The valve member is biased in the closed condition and is responsive to a partial vacuum provided by the user through the passageway for placing the valve member in the open condition.

This invention provides a medical device for delivering volumetric quantities of a first and a second biochemically reactive fluid comprising a first container having an opening, the first container being adapted to contain the first biochemically reactive fluid; a second container having a second fluid opening adjacent the first fluid opening, the second container being adapted to contain the second biochemically reactive fluid; a spray unit for separately atomizing the first and second biochemically reactive fluids into an aerosol with at least one energy source of a liquid energy, a mechanical energy, a vibration energy, and an electric energy; a fluid pressurizer for pressurizing the first and the second biochemically reactive fluids for delivery under pressure through the spray unit onto a surface; and wherein the first and second biochemically reactive fluids first mix on the surface.

Fibrin delivery device and method for forming fibrin on a surface

A precise fluid flow meter fabricated by micromachining techniques measures a wide range of fluid flow rates. Two serial portions of an enclosed channel have different cross-sectional areas, and therefore different flow velocities. The fluid carries the thermal pulse through the flow channel to two sensor elements spaced apart along the channel downstream from the heating element. The transit time of the thermal pulse between the two sensor elements measures the fluid flow velocity.
