Intended Use

The YOGA Microcatheter is intended for use in the peripheral, coronary, and neuro vasculature for the intravascular introduction of interventional/diagnostic devices.

Device Story

YOGA Microcatheter is a variable-stiffness, end-to-end braided, single-lumen catheter; designed for accessing small, tortuous vasculature. Features hydrophilic outer coating for lubricity; PTFE-lined inner lumen facilitates guide wire/device movement. Includes radiopaque marker band at tip for fluoroscopic visualization; luer fitting at proximal hub for accessory attachment; steam-shaping mandrel provided. Used in clinical settings (e.g., cath lab) by physicians; navigated through vasculature under fluoroscopic guidance. Output is the delivery of interventional or diagnostic devices to target sites. Benefits include improved access to complex, tortuous anatomy for minimally invasive procedures.

Clinical Evidence

No clinical studies were performed. Evidence consists of bench testing (visual inspection, dimensional verification, tensile strength, flow rate, burst pressure, coating integrity, trackability) and in vivo animal radiopacity testing. Biocompatibility testing was conducted per ISO 10993 standards, with some results leveraged from predicate devices (ENVOY DA, REVIVE IC).

Technological Characteristics

Variable-stiffness, braided single-lumen catheter. Materials: Pebax, Vestamid, Nylon, PTFE liner, stainless steel reinforcement, 90% Platinum/10% Iridium marker band, Grilamid hub. Dimensions: 150cm length; 2.4F–3.4F OD; 0.024"–0.032" ID. Hydrophilic coating. Sterilization: Ethylene Oxide (SAL 10^-6).

VII. Performance Testing - Animal Radiopacity testing was conducted in an in vivo animal model to ensure the user can Performance visualize the distal end of the catheter under fluoroscopy. Data, Continued

#### Performance Testing - Clinical

No clinical studies were required as appropriate verification and validation of the catheter and packaging modifications were achieved based on the similarities of the proposed device to the predicate device, and from results of bench testing.

#### Sterilization

The YOGA Microcatheter is sterilized using a validated Ethylene Oxide sterilization cycle. Based on similarities with the predicate device, the YOGA Microcatheter can be adopted into the validated sterilization process to ensure sterility assurance level (SAL) of 10th in accordance with ISO 11135-1.

#### Shelf-Life Testing

The YOGA Microcatheter will have a shelf life of 3 years based on the shelf life of currently cleared products, such as ENVOY DA (K140080) and REVIVE IC (K112828). A successful 3-vear shelf life has been demonstrated on the ENVOY DA and the REVIVE IC as well as the sterile barrier system. The materials. manufacturing process and designs have been leveraged for the YOGA Microcatheter. Based on the material and processing methods, it can be concluded that the successful aging testing of the ENVOY DA and the REVIVE IC as well as the sterile barrier system are applicable to the YOGA Microcatheter.
