lntraaortic Balloon Pump With a width of 14 inches and a weight of 95 pounds, the new Model 90T is a modular unit designed for air and ground transport. The pump offers in- stant synchronization of inflation-a timing algorithm that automatically and instantly adjusts timing for changes in patient heart rate and rhythm with- out operator intervention. Even tradi- tionally problematic rhythms such as atria1 fibrillation are automatically tracked. Triggering reliability is aided by a combination of 5 choices of trigger, automatic pacer rejection circuitry and electrosurgical interference suppres- sion.

Femoral Arterial Pressure Device The elastic bandages and sandbags nec- essary to secure continuous pressure on the femoral artery or vein after cardiac catheterization or coronary arteriogra- phy may now be replaced by HOLD” (Hemostatic Occlusive Leverage De- vice).

With HOLD, pressure is maintained for as long as it is clinically desirable by means of an elasticized groin strap held in position by a pelvic apron. The device causes neither skin abrasion nor dis- comfort during removal.

Coronary Sinus Retroinfusion Catheter The Corday@ catheter was developed to provide a method of delivering pharma- cologic agents to the myocardium more effective than intravenous administra- tion. The catheter is placed in the coro- nary sinus and its balloon inflated to block off the coronary sinus. Drugs are

then infused into the heart via a second channel in the catheter and held in place by the inflated balloon. To ensure pa- tient safety, pressure in the coronary sinus is monitored through a third chan- nel while the balloon is inflated.

Additional indications include coro- nary venous visualization, coronary si- nus blood/enzyme sampling, coronary sinus pressure monitoring and myocar- dial cooling during surgery.
