| gastric balloon | An inflatable device implanted in the stomach as an adjunct to therapy of morbid obesity. Specific types include the silicone Garren-Edwards gastric bubble (gegb), approved by the FDA in 1985, and the ballobes balloon. (12 Dec 1998) |

| detachable balloon | A small balloon, attached to the tip of a catheter, which can be released to occlude a vessel. (05 Mar 2000) |
| intra-aortic balloon | An externally and intermittently inflatable balloon placed into the descending aorta and which, on activation during diastole, augments blood pressure and organ perfusion by its pulsatile thrust; then, on deflation, decreases the cardiac work with each systole-the so-called counterpulsation principle-by reducing cardiac afterload. (05 Mar 2000) |
| intra-aortic balloon pump | <cardiology, equipment> A device which is threaded into the aorta that augments the strength of the hearts contraction. The counter pulsation, produced by the inflation of a balloon within the aorta, provides an rhythmic increase in aortic pressures. The net effect is an increase in coronary artery blood flow. Intra-aortic balloon pump is a temporary lifesaving measure that is used to treat severe cardiac damage due to a massive heart attack. (27 Sep 1997) |
| intra-aortic balloon pumping | Counterpulsation in which a pumping unit synchronised with the patient's electrocardiogram rapidly fills a balloon in the aorta with helium or carbon dioxide in early diastole and evacuates the balloon at the onset of systole. As the balloon inflates, it raises aortic diastolic pressure, and as it deflates, it lowers aortic systolic pressure. The result is a decrease in left ventricular work and increased myocardial and peripheral perfusion. (12 Dec 1998) |
| laser-assisted balloon angioplasty | <cardiology, procedure> Techniques using laser energy in combination with a balloon catheter to perform angioplasty. These procedures can take several forms including: 1. Laser fibre delivering the energy while the inflated balloon centres the fibre and occludes the blood flow. 2. Balloon angioplasty immediately following laser angioplasty. 3. Laser energy transmitted through angioplasty balloons that contain an internal fibre. (05 Mar 2000) |
