A detachable balloon system includes an inflatable balloon with a self-sealing valve. The balloon has an elastomeric membrane and a proximal opening. The self-sealing valve is made up of a valve body for receiving an inflation instrument to inflate the balloon. The valve body is preferably formed of a biocompatible elastomeric material and includes a base portion and a sealing portion. The base portion is bonded to the elastomeric membrane so as to seal the proximal opening of the balloon. The sealing portion is located within the balloon and extends distally from the base into the balloon. The sealing portion is compressibly sealable in response to a pressure within the balloon following inflation of the balloon and removal of the inflation instrument. A balloon dispenser for housing a balloon prior to receipt of an inflation instrument is also described.

A linear delivery system and method for deployment of a detachable balloon at a target site in a patient in vivo is disclosed. The system includes a unitary sheath assembly having a retractable shaft and base, and a balloon delivery device configured for insertion through the lumen of the sheath assembly. The linear method of delivery overcomes disadvantages and limitations caused by undesirable movement of the assembly or separation of the catheter from the delivery system during inflation of the balloon. The linear delivery system further includes properties that increase the ease of use and stability of the device so as to reduce the effort required by the physician and discomfort experienced by the patient during deployment of a detachable balloon.

An apparatus for gripping a centrifuge bowl includes a single pivoting retaining arm having a stationary jaw. The retaining arm is capable of pivoting into and out of position such that the centrifuge bowl can be loaded and unloaded. A moveable jaw pivots about the retaining arm to lock the stem of the centrifuge bowl against the stationary jaw when actuated by a latching mechanism. At the same time, a catch on the latching mechanism locks the retaining arm to a latching shaft.

A fluid flow apparatus includes a peristaltic pump rotor mounted to a deck module assembly. A disposable software set is provided which includes a cassette which has a primary flexible tube and a pump platen adjacent to which the primary flexible tube resides. Tubing with blood processing bags are coupled to the manifold along with the input port of the rotor of a disposable blood processing centrifuge bowl. The software set also includes a three-to-one manifold which connects the primary tube to a plurality of secondary flexible tubes. Fluid flow through the secondary flexible tubes is controlled by a plurality of pinch valves which pinch the secondary tubes closed against closing surfaces on the cassette. A deck module assembly allows a user to properly secure the cassette relative to the pump rotor and the pinch valves. A flat surface is provided on the manifold to couple sonic radiation into the manifold and sense the presence of fluids therein.

A volume sensor is described for automating an extracorporeal system used for the recovery and concentration of salvaged blood. The system includes a disposable plastic reservoir in which blood is collected from the surgical site and stored for processing. Volume is sensed in one embodiment by a strain gage device which is sensitive to vertical forces. In another embodiment volume is sensed by measuring the transit time of an ultrasonic pulse-echo signal generated by piezoelectric transducer.

A fluid flow apparatus includes a peristaltic pump rotor mounted to a deck module assembly. A disposable software set is provided which includes a cassette which has a primary flexible tube and a pump platen adjacent to which the primary flexible tube resides. Tubing with blood processing bags are coupled to the manifold along with the input port of the rotor of a disposable blood processing centrifuge bowl. The cassette is removably secured to the hardware apparatus such that the flexible tube contacts both the platen of the cassette and the rollers of the pump rotor. The pump rotor is rotated to induce a fluid flow through the primary flexible tube. The software set also includes a three-to-one manifold which connects the primary tube to a plurality of secondary flexible tubes. Fluid flow through the secondary flexible tubes is controlled by a plurality of pinch valves which pinch the secondary tubes closed against closing surfaces on the cassette. A deck module assembly allows a user to properly secure the cassette relative to the pump rotor and the pinch valves.
