MEDICAL DEVICES : Ensuring the safety and efficacy of through preclinical medical device testing

Porsolt is a leading provider of preclinical medical device testing services. We offer a comprehensive range of services to help you ensure the safety and efficacy of your devices, from initial concept to market launch.

We understand that the development of a new medical device is a complex and challenging process, especially in therapeutic areas (dermatology, oncology, pain, etc.) with limited treatment options. That’s why we work with you every step of the way to ensure that your device is safe and effective for patients.

Cytotoxicity is the ability of a substance to damage or kill cells. Preclinical medical devices are often tested for cytotoxicity to ensure that they are safe for use in humans. Our medical device CRO services for medical device testing include cytotoxicity testing capabilities.

Genotoxicity is the ability of a substance to damage or alter the genetic material (DNA) of a cell. This can lead to cell death, mutations, and cancer. Genotoxicity testing is an important part of the development process for preclinical medical devices testing, and is typically conducted by a medical device testing laboratory.

Irritation is a local inflammatory reaction to a substance or condition that causes redness, swelling, pain, and itching. It is an important property to consider during preclinical medical device development, as it can affect the safety of the device.

Skin Sensitization

Skin sensitization is a serious problem, as it can lead to a variety of allergic reactions, including contact dermatitis, hives, and even anaphylaxis. This is why it is important to test medical devices for skin sensitization before they are used in human subjects. Our medical device CRO services offer skin sensitization capabilities which can be used to assess the skin sensitization potential of medical devices in vitro, using cell cultures or animal models.

Toxicity is the degree to which a substance can cause harm to living organisms. Toxicity can be caused by a variety of substances, including objects and devices, chemicals, drugs, and even radiation. Preclinical medical devices development can also be toxic, if they are not properly designed and tested.

Porsolt’s approach to preclinical medical device testing is based on intricate medical device laboratory testing strategies that simulate the interactions between devices and biological systems. These activities allow us to uncover potential allergic reactions or adverse responses, including deep vein thrombosis histology, and our meticulous analysis aids in identifying sensitization risks. This information can then be used to refine device materials and design to ensure patient safety and regulatory compliance.
