Intended Use

The Rosch-Uchida Transjugular Liver Access Set is intended for transjugular liver access in diagnostic and interventional procedures. The Ring Transjugular Intrahepatic Access Set is intended for transjugular liver access in diagnostic and interventional procedures.

Device Story

Transjugular Liver Access Sets facilitate percutaneous access to hepatic vasculature and portal vein for diagnostic/interventional procedures. Sets include core components (stiffening cannula, needle stylet, Teflon catheters) and accessories (introducer sets, selective catheters, wire guides). Operated by physicians in clinical settings. Core components puncture hepatic vein, liver parenchyma, and portal vein to create access pathway. Device visibility via radiopacity aids physician navigation. Output is physical access pathway for subsequent interventional tools. Benefits include minimally invasive access to liver vasculature.

Clinical Evidence

Bench testing only. No clinical data. Testing included biocompatibility (ISO 10993-1), radiopacity (ASTM F640-12), corrosion resistance, tensile strength, torque, liquid/air leakage, burst pressure (ISO 10555-1:2013), and wire guide performance (ISO 11070:2014). All components met predefined acceptance criteria.

Technological Characteristics

Components: stainless steel needles/cannulae, Teflon/polyethylene catheters, wire guides. Materials: PTFE, stainless steel, Nylon, HDPE. Sterilization: EtO (SAL 10^-6). Radiopacity: Platinum/Iridium marker bands. Standards: ASTM F640-12 (radiopacity), ISO 10555-1 (catheter performance), ISO 11070 (introducer/wire guide performance), ISO 10993-1 (biocompatibility).

Indications for Use

Indicated for transjugular liver access during diagnostic and interventional procedures in patients requiring such access.

#### IV. DEVICE DESCRIPTION

The Transjugular Liver Access Sets are comprised of various components that facilitate transjugular access to the liver for the purpose of performing diagnostic and interventional procedures. The sets are grouped into two basic types: the Ring Transjugular Intrahepatic Access Set and the Rösch-Uchida Transjugular Liver Access Set. Each set includes a core component comprised of a combination of either a stiffening cannula/Teflon catheter or needle stylet/Teflon catheter that facilitates access into the hepatic vasculature and the creation of a pathway into the portal vein. Other components included in some of these sets are a Check-Flo Introducer Set. selective catheters, and wire guides. The following components of the subject device sets have received prior 510(k) clearance: the Flexor Check-Flo Introducer Set (K142829), the van Andel Catheter (K170616), and the Torcon NB Advantage Catheter (K161822). Each component is individually packaged in an inner Tyvek pouch. All inner pouches for a given set configuration are packaged within an outer Tyvek pouch.

The Ring Transjugular Intrahepatic Access Set's core component is a Colapinto Needle and Catheter Assembly. The Colapinto Needle is a hollow 16 gage stainless steel stiffening cannula

## VII. PERFORMANCE DATA

The subject devices underwent the applicable testing listed below to ensure reliable design and performance under the testing parameters. Performance and biocompatibility testing was conducted in accordance with applicable FDA guidance documents to confirm the reliable performance of critical device characteristics. Testing on specific introducer and catheter components (the Van Andel Catheter, the Torcon NB® Advantage Catheter, and the Flexor Check-Flo Introducer Set) is not included because these devices have been previously cleared by the FDA under 510(k) numbers K170616, K161822, and K142829, respectively.

Biocompatibility Testing - - Per ISO 10993-1 and FDA guidance, testing for Cytotoxicity, Sensitization, Irritation, Acute Systemic Toxicity, Hemocompatibility(Hemolysis, Complement Activation, In Vivo Thrombogenicity), and Material-mediated Pyrogenicity tests were performed on all components of the subject device or on representative devices. All test results met the acceptance criteria, where applicable, or demonstrated that the device is biocompatible.

Performance Testing - The components in the subject device were subjected to applicable testing to assure reliable design and performance under the testing parameters. The tests for the core components (i.e., set components that puncture through the hepatic vein, liver parenchyma, and portal vein) and the accessories are listed below. In addition to the tests listed below, dimensional, surface and compatibility analysis was performed on all components in the subject

{7}------------------------------------------------

device to verify that the critical dimensions met the predefined acceptance criteria, that the surfaces of the devices were from defects, and that the set components were compatible.

# VIII. CONCLUSIONS

The results of testing provide reasonable assurance that the Transjugular Liver Access Sets have been designed so that they conform to the requirements of their intended use. The available evidence demonstrates that the subject devices are substantially equivalent to the predicate device, the GORE TIPS Set (K152913), and do not raise new questions of safety or effectiveness. This supports a determination of substantial equivalence.
