419 studies
The device was cleared through the FDA 510(k) pathway on July 28, 1983, by Austin Biological Laboratories. It is classified as a Class 1 device under product code JTR.
What It Is
Lyophilized microorganisms are freeze-dried biological agents used in clinical applications such as embolization. They are intended to maintain viability and functionality over extended storage periods.
Clinical Applications
Commonly used in scenarios requiring long-term storage of microorganisms, such as in laboratories or clinical settings where immediate use is not feasible. They are also used in research and therapeutic applications.
Evidence Summary
The literature includes 11 studies, ranging from 1963 to 2023, covering various aspects of lyophilized microorganisms. Study types include randomized controlled trials and observational studies.
Reported Outcomes
Published studies report that lyophilized microorganisms maintain viability and functionality over extended periods. They are effective in applications such as protein degradation and bioplastic degradation.
Safety Profile
Reported complications include potential loss of viability and activity if storage conditions are not optimized. No significant adverse events were noted in the reviewed studies.
Evidence Limitations
The evidence is limited by the small number of studies focusing on specific clinical outcomes. Further research is needed to explore the full range of clinical applications and long-term safety.
