Abstract:

A vacuum demand value ( ) is capable of delivering a flowable material. 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 tubing. A valve member ( ) is located along the intermediate segment ( ). The valve member ( ) has a closed condition wherein 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.

International Classification:

A61M 3700

US Classification:

604 82

Abstract:

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.

Abstract:

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.
