Perfectus Biomed work to a number of standard and customised medical device test methods.

Infections relating to medical implants such as catheters, stents and joint prosthesis can result in a number of healthcare problems. These include local and systemic infection, implant replacement, patient pain and discomfort and associated healthcare costs. An improvement in the antimicrobial nature of medical implants therefore helps to improve patient well-being while also minimising healthcare costs.

We can help support your research and development into microbial infection control of medical devices. We offer a range of test methods, including coating efficacy, endotoxin detection, bioburden assessment and implantable device assessment. Standard test methods include ASTM D7907, BS EN 1616, BS EN ISO 10993 and ISO 22196, as well as GLP compliant testing.

Please contact us to discuss how we can support research and development programmes related to infection control on medical devices and support your product through medical device regulations.

Medical Devices

We can use the PMM to test for bacterial adhesion to and host cell toxicity of experimental devices.

Urogenital Health

Since much of the human genital tract is composed of mucosal tissue, the PMM can be used for predictive preclinical testing of compounds or products related to urogenital health.

Inflammation and Biocompatibility

The PMM offers a unique way to investigate inflammatory cytokine concentrations in a cost-effective manner. We can perform ELISAs and multiplex assays to determine whether experimental compounds are pro- or anti-inflammatory.

Infectious Diseases

Mucosal tissue is an ideal environment for microbial growth, making the PMM an excellent application for testing the efficacy of products to treat infectious disease pathogens. We can test for efficacy against planktonic and biofilm infections with this model.
