L. Gore & Associates, Inc. - **Product Code:** [DYB](/submissions/CV/subpart-b%E2%80%94cardiovascular-diagnostic-devices/DYB.md) - **Decision Date:** Nov 20, 2012 - **Decision:** SESE - **Submission Type:** Traditional - **Regulation:** 21 CFR 870.1340 - **Device Class:** Class 2 - **Review Panel:** Cardiovascular ## Indications for Use The GORE® DrySeal Sheath with hydrophilic coating is intended to be inserted in the vasculature to provide a conduit for the insertion of endovascular devices while minimizing blood loss associated with such insertions. ## Device Story The GORE® DrySeal Sheath is an introducer sheath system used in the vasculature to facilitate endovascular device insertion while minimizing blood loss. The device comprises a polyethylene introducer sheath with a tapered tip and radiopaque marker band, a dilator for vessel access, and a DrySeal Valve. The valve consists of an outer silicone tube and an inner film tube; the space between these tubes is pressurized with 2.5mL of saline via a provided syringe to create a seal. The device is used by clinicians in a procedural setting. The addition of a hydrophilic coating improves lubricity during insertion. The device functions as a mechanical conduit; it does not involve electronic processing, AI, or software. ## Clinical Evidence No clinical data. Substantial equivalence supported by bench testing, including biocompatibility (ISO 10993), sterilization validation (ISO 11135-1), packaging integrity, product shelf-life, and design verification testing (lubricity and particulation comparative analysis). ## Technological Characteristics Polyethylene introducer sheath with tapered tip and radiopaque marker band; DrySeal Valve (silicone/film construction) pressurized with 2.5mL saline; hydrophilic coating for lubricity. Sterilization via validated methods. Complies with ANSI/AAMI/ISO 10993 for biocompatibility. ## Regulatory Identification A catheter introducer is a sheath used to facilitate placing a catheter through the skin into a vein or artery. ## Predicate Devices - GORE® DrySeal Sheath ([K093791](/device/K093791.md)) ## Submission Summary (Full Text) > This content was OCRed from public FDA records by [Innolitics](https://innolitics.com).

The introducer sheath is a polyethylene tube with a tapered leading tip and marker band incorporated within the sheath material to allow identification under fluoroscopy. The sheath has an insert molded hub on the trailing end, which is attached to the GORE® DrySeal Valve. The GORE® DrySeal Valve is comprised of an outer silicone tube and an inner film tube. The region between the silicone tube and film tube is pressurized by injecting 2.5mL of saline into the space, using the provided syringe, during procedural preparation of the device. The dilator has a tapered leading end and provides dilatation of the access vessel. A mark on the trailing end of the dilator ensures correct positioning of the dilator within the sheath. ### Device Modification A hydrophilic coating has been added to the GORE® DrySeal Sheath. No other changes were made to the proposed device from that cleared under K093791. #### Predicate Devices #### GORE® DrySeal Sheath with hydrophilic coating: GORE® DrySeal Sheath (K093791) #### Indications The GORE® DrySeal Sheath with hydrophilic coating is intended to be inserted in the vasculature to provide a conduit for the insertion of endovascular devices while minimizing blood loss associated with such insertions. {2}------------------------------------------------ ### Biocompatibility Results for all biocompatibility testing demonstrate that the materials used meet the requirements of ANSI/AAMI/ISO 10993. | Test | Test Description | Result
