Review
The Cutting Balloon is a unique angioplasty device used in percutaneous coronary interventions. The advantage of the Cutting Balloon is its ability to reduce vessel stretch and vessel injury by scoring the vessel longitudinally rather than causing an uncontrolled disruption of the atherosclerotic plaque. The atherotomes deliver a controlled fault line during dilatation to ensure that the crack propagation ensues in an orderly fashion. Lower balloon inflation pressures (4 8 atmospheres) are recommended with the Cutting Balloon. The Cutting Balloon also dilates the target vessel with less force to decrease the risk of a neoproliferative response and in-stent restenosis.

We investigated the use of ultralow profile balloon catheters (Scimed ACE, USCI Probe, Cordis, Orion) for coronary angioplasty through 6 French diagnostic catheters (Schneider, Cordis). Contrast injection was assisted with a Hercules pump (Cordis) in all cases. During 21 procedures, angioplasty of 27 lesions in 20 selected patients was attempted (1.3 lesion/procedure). Twelve lesions were in the right, 10 in the left anterior descending, and 5 in the left circumflex coronary artery. Balloon size varied between 2.5 and 3.5 mm. Twenty lesions could be successfully dilated (74%) through the 6 French catheter and 7 lesions required an exchange to a 7 French angioplasty guiding catheter. For 5 cases, another balloon was also necessary to complete the procedure. The final overall success rate was 100% per patient and per lesion and there were no major complications. Despite the small internal catheter lumen (1.22 mm) coronary visualization was adequate, and mechanical support was good. Failures of 6 French catheters were attributed to insufficient torque control and excessive friction when the balloon crossed the tapered end of the diagnostic catheter. Coronary angioplasty through a diagnostic 6 French catheter is feasible and may represent a reasonable alternative for simple cases that are done during the same session as the diagnostic angiography. Once available, 6 French high flow angioplasty guiding catheters without a tapered tip should improve success while retaining the advantage of a small femoral puncture site.

Today, the majority of coronary stents are balloon-expandable and are deployed using a balloon-tipped catheter. To improve deliverability, the membrane of the angioplasty balloon is typically folded about the catheter in a pleated configuration. As such, the deployment of the angioplasty balloon is governed by the material properties of the balloon membrane, its folded configuration and its attachment to the catheter. Despite this observation, however, an optimum strategy for modelling the configuration of the angioplasty balloon in finite element studies of coronary stent deployment has not been identified, and idealised models of the angioplasty balloon are commonly employed in the literature. These idealised models often neglect complex geometrical features, such as the folded configuration of the balloon membrane and its attachment to the catheter, which may have a significant influence on the deployment of a stent. In this study, three increasingly sophisticated models of a typical semi-compliant angioplasty balloon were employed to determine the influence of angioplasty balloon configuration on the deployment of a stent. The results of this study indicate that angioplasty balloon configuration has a significant influence on both the transient behaviour of the stent and its impact on the mechanical environment of the coronary artery.

Balloon angioplasty was introduced among the armament of therapy for coronary heart disease in 1977 by Gruentzig in Zurich. Since the first case was successful, this method of treatment spread out rapidly so that at the present time, more than 400,000 procedures are being performed per year in the U.S. The reasons for such on explosive success includes the relative safety of the procedure, the reduction in cost as compared to surgical bypass procedures, the short in-hospital stay, and short recovery time.

Review
Coronary artery disease affects patients worldwide and is a major cause of morbidity and mortality. Historically, the treatment approach for patients with coronary syndromes has been surgical. In the 1970s, percutaneous balloon angioplasty was introduced, leading to creation of a new field of interventional cardiology, which allowed a non-surgical minimally invasive approach to treat patients with coronary artery disease. However, the major limitations of balloon angioplasty were acute vessel closure and later restenosis. The introduction of bare metal stents and then drug-eluting stents (DES) revolutionized the practice of interventional cardiology and allowed for safe treatment of increasingly complex coronary artery lesions. Although drug-eluting coronary stents improve patient outcomes, they still have limitations. These limitations may arise from delayed endothelialization, local vessel hypersensitivity and endothelial dysfunction secondary to the drug elution, the durable polymer coating, or the stent scaffold. This comprehensive review will discuss the evolution of intracoronary stents from their introduction to current utilization of DES as well as future research on bioabsorbable stents and polymers.
