An Expandable Introducer Sheath

Patent No. EP3738533 (titled "An Expandable Introducer Sheath") was filed by Freudenberg Medical on Aug 25, 2015. The application was issued on Feb 15, 2023.

Patent Summary

An expandable introducer sheath for inserting a medical device into a patient's body vessel comprises a body extending along an axis from a proximal end to a distal end. The body consists of an inner layer, an outer layer, and an expandable reinforcement member disposed between these layers. This reinforcement member is configured to radially expand as the medical device is axially advanced or retracted through the sheath, subsequently retracting to its original diameter upon the device's exit. Additionally, a protective sheath is disposed in an overlaying and surrounding relationship with the outer layer. This protective sheath is characterized by its ability to radially expand in conjunction with the outer layer and expandable reinforcement member during the axial movement of the medical device.
