Description / Abstract:
General
This technical information report (TIR) addresses vascular
exposure to particles arising from the manufacturing environment
for vascular medical devices and from the use of vascular medical
devices. It is intended to assist vascular medical device
manufacturers in determining the source of particulates,
establishing product particulate limits, defining appropriate test
methods, and assessing the clinical relevance of particulate
contamination.
Inclusion
This document specifically includes particles generated as a
result of manufacturing, packaging, and acute application of a
vascular medical device or any accessories bundled with the device
used for insertion and implementation of the product. In the
absence of bundled accessories, this TIR recommends testing the
device in conjunction with commonly used or suggested
accessories.
Exclusion
This TIR does not address particulates that arise from
degradation or wear of the device, whether these particles be
either deliberate or nondeliberate. This document specifically
excludes particles arising from the operating room or clinical
environment in which the device might be implemented. Furthermore,
the scope of this document specifically excludes visible particles
that would normally be found using standard visual inspection
techniques that are part of the manufacturing process. This
document does not address patient-generated particles that might be
produced before, during, or following implementation of the device.
Liquids are not considered to be particles in the context of this
document. In addition, therapeutic particles intentionally
delivered are not included in this document, although
characterization of these particles using methods described in this
document may be appropriate.
