This premarket notification proposes the following changes to the current legally marketed 40 cc Grande NTTM: 1. The proposed 40 cc Grande™ has a polyurethane central lumen. The polvurethane central lumen design is similar to that of the predicate Model 940 with a smaller ID and OD. ### DEVICE DESCRIPTION പ് The proposed 40 cc Grande™ consists of a polyurethane blend symmetrical balloon at the distal end of a polyurethane-covered nylon The balloon is coated with a thin layer of silicone fluid. shaft. A polvurethane central lumen runs throughout the length of the catheter and terminates at the distal tip. This central lumen may be used to pass the device over a guidewire. The balloon is supplied prewrapped for insertion and supplied with a 0.025 inch extra stiff quidewire and 10 F introducer. ### F. INDICATIONS FOR USE The indications for use for the 40 cc Grande™ is identical to that of the currently marketed predicate devices. The indications are as follows: - · Refractory power failure. - · Cardiogenic shock. - · Unstable refractory angina. - · Impending or extending myocardial infarction (MI). Hemodynamically significant mechanical complications secondary to acute MI: - · Ventricular septal defect. - · Mitral valve regurgitation. - · Papillary muscle rupture. - · Angiography/Angioplasty patients. - · Septal shock. #### C. TECHNOLOGICAL CHARACTERISTICS The 40 cc Grande™ is Identical to the predicate 40 cc Grande NTTM except for the central lumen which is made of polyurethane (same as predicate Model 940 with smaller ID and OD). Test data and information demonstrates that the use of the 40 cc Grande™ is substantially equivalent to the performance of the predicate devices on the BSC/CA 3001, Datascope Systems 90 and 97, St. Jude/Aries 700, Kontron KAAT and Bard H-8000 IABP's. {2}------------------------------------------------ ### H. NONCLINICAL TESTS ### 1. Initial Performance Testing: To demonstrate the unwrapping and integrity of the 40 cc Grande™ post insertion and removal, test samples were tested on the BSC/CA 3001 IABP. All the proposed 40 cc Grande™ IAB's opened (unwrapped) per the Directions for Use and QA final acceptance criteria. Demonstration that the proposed 40 cc Grande™ can be inserted and removed from it's introducer twice, inserted into another introducer and passed the unwrapping test demonstrates the integrity of the device post insertion and removal. ### 2. Sheathed Insertion Test: The force required to insert the 40 cc Grande™ through it's introducer, over it's guidewire at 34.8 oz was demonstrated to be substantially equivalent to the force required to insert the predicate Model 940 at 30.1 OZ. - 3. Sheathless Insertion Test: The tightest restriction that the 40 cc Grande™ can pass through 100% of the time is 0.100 inch which is substantially equivalent to the predicate 40 cc Grande NT™ at 0.100 inch, the 40 cc Datascope 9.5 F Percor-Stat at 0.100 inch and the 40 cc 9 F Kontron/Arrow IAB at > 0.105 inch. This restriction is well below the 0.118 inch dilator size provided for use with the sheathless introduction technique. - 4. Maximum Pumping Rate Limit Test: The maximum pumping rate limit, defined as the maximum pumping rate at which the balloon is able to inflate and deflate fully (greater than or equal to 90% of it's nominal volume), was measured for the 40 cc Grande™ on the BSC/CA 3001 IABP. The maximum pumping rate limit was 175 bpm which is substantially equivalent to the predicate 40 cc Grande NTM at 170 bpm and greater than the Model 940 at 140 bpm. The proposed 40 cc Grande™ combined inflation/deflation time of 245 msec compares favorably with the combined inflation/deflation times of the predicate Model 940 at 275 msec and 40 cc Grande NTTM at 264 msec. - 5. Reliability and Integrity Test: The reliability of the 40 cc Grande™ was compared to that of the predicate 40 cc Grande NTTM and Model 940 by pumping test samples for a minimum of 3.6 million cycles. The 40 cc Grande™ test samples were all able to cycle as reliably as the predicate devices. Dimensional inspection, visual inspection for signs of surface wear, and leak testing were performed following reliability testing. No changes in dimensions, signs of surface wear or leaks were noted. {3}------------------------------------------------ Following reliability testing, dimensional and visual inspections and leak testing, the 40 cc Grande™ test samples were subjected to a maximum pumping rate limit test on the BSC/CA 3001. The maximum pumping rate limit post-reliability was 176 bpm which compares well with the prereliability value of 175 bpm. Inflate and deflate times were also found comparable post-reliability versus pre-reliability testing. ### 6. Trackability Test: 40 cc Grande™ test samples were inserted over their guidewire, into position, and withdrawn as a set to demonstrate that the catheters can perform with their insertion accessories. All the 40 cc Grande™ as well as the predicate devices were able to track their guidewire into place without There were no catheter kinks, no guidewire kinks, nor any incident. problems encountered inserting or removing the catheters through their introducer. ## 7. Transmembrane Pressure and Volume Measurement Test: The volume of the 40 cc Grande™ at a transmembrane pressure of 50 mmHq was found to be 41.6 cc which meets the acceptance criteria of 40 cc +/- 5% and is substantially equivalent to the predicate 40 cc Grande NT™ at 41.7 cc. At a 40 cc displacement, the 40 cc Grande™ transmembrane pressure on average will be 21.5 mmHg which meets the acceptance criteria of < 50 mmHg and is substantially equivalent to the predicate 40 cc Grande NTTM at 26.7 mmHg. 8. Kink Resistance Test: 40 cc Grande™ test samples were manufactured, sterilized, aged to their intended shelf life of 2 years and tested for their ability to bend around the smallest radius without failure. The proposed 40 cc Grande™ with a mean kink radius of 0.51 inch was found to be less than the predicate Model 940 at 0.54 inch. ### CUNICAL TESTS . No clinical testing was was was and performed by Boston Scientific Corporation/Cardiac Assist in support of this premarket notification. ### . ل PACKAGING AND STERILIZATION There are no changes to the packaging and sterilization of the 40 cc Grande™ as compared to the predicate devices. The catheters are placed in a plastic tray and sealed into Tyvek/Mylar pouches and sterilized using 100% Ethylene Oxide gas. Ethylene oxide gas residuals and bacterial endotoxin levels are monitored for compliance with maximum release limits. {4}------------------------------------------------ ### POTENTIAL COMPLICATIONS K.

The intended use of the 40 cc Grande. " remains identicalto that of the currently marketed IABC's. All of the devices are intended to provide temporary circulatory support of the left ventricle through controlled mechanical displacement of a volume of blood in the aorta. The mechanical action of the IAB catheter therapy lowers the cardiac workload by two means : - Systolic unloading, as noted by a reduction in the patient's systolic 1. - pressure, which provides reduced myocardial oxygen consumption (MVO,). . . - Diastolic augmentation which provides an increase in the mean 2. aortic pressure and leads to an improvement in systemic and coronary arterial perfusion. Balloon pump therapy is achieved by inserting and intra-aortic balloon catheter into the descending thoracic aorta via the common femoral Balloon inflation is timed to occur during diastole, beginning arterv. with the aortic valve closure. The balloon remains inflated until the onset of left ventricular ejection or systole, then rapidly deflates, reducing the aortic pressure, which in turn reduces the afterload.
