EXPANDABLE SHEATH - A simplified explanation of the abstract

This abstract first appeared for US patent application 18747761 titled 'EXPANDABLE SHEATH

Simplified Explanation: The patent application describes an expandable sheath with multiple layers designed to provide radial force and encapsulation for medical devices.

• The expandable sheath consists of a first polymeric layer, a braided layer made of filaments, a resilient elastic layer, and a second polymeric layer.
• The braided layer and elastic layer are positioned between the first and second polymeric layers, providing support and flexibility to the sheath.
• The elastic layer applies radial force to the braided layer and the first polymeric layer, enhancing the expandability of the sheath.
• The second polymeric layer is bonded to the first polymeric layer, ensuring the encapsulation of the braided and elastic layers within the sheath.

Potential Applications: 1. Medical devices such as stents or catheters could benefit from the expandable sheath's design. 2. The sheath could be used in minimally invasive procedures where flexibility and support are crucial. 3. It may find applications in various surgical interventions requiring precise control and expandability.

Problems Solved: 1. Provides radial force and support to medical devices during procedures. 2. Ensures encapsulation and protection of delicate components within the sheath. 3. Enhances the expandability and flexibility of medical devices for improved performance.

Benefits: 1. Improved control and precision during medical procedures. 2. Enhanced flexibility and support for medical devices. 3. Increased durability and protection for delicate components.

Commercial Applications: The expandable sheath could be utilized in the medical device industry for various procedures, potentially improving patient outcomes and procedural efficiency.

Questions about Expandable Sheaths: 1. How does the expandable sheath enhance the performance of medical devices during procedures? 2. What are the potential applications of the expandable sheath technology in the medical field?

Original Abstract Submitted

An expandable sheath is disclosed herein, which has a first polymeric layer and a braided layer positioned radially outward of the first polymeric layer. The braided layer includes a plurality of filaments braided together. The expandable sheaths further include a resilient elastic layer positioned radially outward of the braided layer. The elastic layer is configured to apply radial force to the braided layer and the first polymeric layer. The expandable sheath further includes a second polymeric layer positioned radially outward of the elastic layer and bonded to the first polymeric layer such that the braided layer and the elastic layer are encapsulated between the first and second polymeric layers. Methods of making and using the devices disclosed herein are also disclosed, as are crimping devices that may be used in methods of making the devices disclosed herein.
