The Amsco V-PRO 1 Plus Low Temperature Sterilization System, with VAPROX HC Sterilant, is a vaporized hydrogen peroxide sterilizer intended for use in the terminal sterilization of cleaned, rinsed and dried reusable metal and nonmetal medical devices used in healthcare facilities. The two pre-programmed sterilization cycles; the Lumen and the Non Lumen Cycles operate at low pressure and low temperature and are thus suitable for processing medical devices sensitive to heat and moisture.
The Amsco V-PRO 1 Plus Low Temperature Sterilizer System's (Lumen Cycle) was cleared under (K062297) can sterilize *'
· Instruments with diffusion-restricted spaces such as the hinged portion of forceps and scissors
* Medical, devices with a single stainless steel lumen with:
o an inside diameter of.1 mnm or larger and a length of a 125 mm or shorter
o an insider diameter of 2 mm or larger and a length of 250 mm or shorter
o an inside diameter of 3 mm or larger and a length of 400 mm or shorter
The validation testing for all lumen sizes was conducted using a maximum of twenty (20) lumens per load. Hospital loads should not exceed the maximum number of lumens validated by this testing. The validation studies were performed using a validation load consisting of two instrument trays and two pouches for a total weight of 19.65 lbs.
The Amsco V-PRO 1 Plus Low Temperature Sterilization System's (Non Lumen Cycle) the subject of this (K083097) can sterilize**:
Non-lumened instruments including non-lumened instruments with stainless steel diffusion-restricted areas such as the hinged portion of forceps or scissors.
** The validation studies were conducted using a validation load consisting of two instrument trays and two pouches for a total weight of 19.65 lbs.
