The Flexseal Introducer Sheath was cleared by the FDA via the 510(k) pathway on May 30, 2019. It is manufactured by Freudenberg Medical Mis and classified as a Class 2 device.

What It Is

The Flexseal Introducer Sheath is a medical device with a hydrophilic coating designed to facilitate vascular access by reducing friction during insertion. It is primarily used in embolization procedures to introduce catheters and other devices into the vascular system.

Clinical Applications

Commonly used in procedures involving embolization coils and liquid agents, the Flexseal Introducer Sheath is utilized in scenarios requiring smooth and atraumatic vascular access, particularly in complex or tortuous vascular anatomies.

Evidence Summary

The available literature includes 10 studies ranging from case reports to pilot studies, published between 2021 and 2023. These studies explore various aspects of hydrophilic coatings and their impact on device performance and safety.

Reported Outcomes

Published studies report that the hydrophilic coating on the Flexseal Introducer Sheath enhances deliverability and reduces vessel trauma. However, there are concerns about potential polymer embolization, which could lead to adverse outcomes.

Safety Profile

Reported complications include the potential for hydrophilic polymer embolization, which may result in ischemia, infarction, or death. These findings highlight the importance of monitoring for adverse events during and after procedures.

Evidence Limitations

The evidence is limited by the small number of studies specifically focused on the Flexseal Introducer Sheath. Further research is needed to fully understand the long-term safety and efficacy of the hydrophilic coating in diverse clinical settings.
