This experimental study was conducted to evaluate the microbiological and mechanical risks of reusing angioplasty catheters after decontamination and resterilization. The catheters studied were decontaminated in an ultrasound chamber, rinsed, dried, wrapped, and resterilized at 25 or 35 Kgray. Steri

โฆ Synopsis
titate the amount of pyrogen present in this setting. Of greatest importance is an evaluation of how much pyrogen is present, rather than its absolute presence or absence. Acceptable levels of pyrogen in medical devices have been defined. According to United States Pharmacopeia guidelines, catheters should be cut into 1-inch sections and extracted with 400 ml of pyrogen-free water. The extract is tested using the Lirnulus amebocyte lysate method. The maximum amount of endotoxin allowed is 20 endotoxin units per device [2].

Manipulation of thin-walled coronary guiding catheters, especially directional coronary atherectomy guides, may sometimes be difficult. This is particularly so in patients with tortuous or ectatic aorto-iliac arterial systems. To improve torque transmission and eliminate kinking, the introducer cath
