Intended Use
The AXS Infinity LS Plus Long Sheath is indicated for the introduction of interventional devices into the peripheral, coronary, and neuro vasculature.
Device Description
The AXS Infinity LS Plus Long Sheath is a variable stiffness catheter that has a catheter shaft reinforced with a stainless-steel mixed coil design (single wind and cross coil wind). It has a radiopaque Platinum/Iridium marker band on the distal end. The distal 10 cm of the AXS Infinity LS Plus Long Sheath has a hydrophilic coating which reduces the insertion force and allows the catheter to traverse the vasculature more easily. The catheter has a maximum average outer diameter of 0.109", where no point is > 0.112" and a nominal inner diameter of 0.091". It is available in three working lengths: 70 cm, 80 cm, and 90 cm. The AXS Infinity LS Plus Long Sheath has a PTFElined lumen. The AXS Infinity LS Plus Long Sheath is inserted at a vascular access point to provide access to the target site and once in place, provides a reinforcing conduit for other intravascular devices. Accessories included with the device are a Tuohy-Borst Hemostasis Valve and a Vessel Dilator. The accessories are identical to those in the previous clearance (K172468). The AXS Infinity LS Plus Long Sheath is supplied sterile, non-pyrogenic, and intended for single use only.
More Information

Not Found

No
The device description and performance studies focus on the physical characteristics and mechanical performance of a catheter sheath, with no mention of software, algorithms, or data processing that would indicate AI/ML.

No
The device is described as a 'catheter' and is indicated for 'introduction of interventional devices' and providing a 'reinforcing conduit for other intravascular devices'. It facilitates therapeutic interventions but is not therapeutic itself.

No

Explanation: The device is indicated for the "introduction of interventional devices" and provides a "reinforcing conduit for other intravascular devices," clearly stating its purpose is for interventional procedures, not diagnosis.

No

The device description clearly details a physical catheter with a reinforced shaft, marker band, hydrophilic coating, and a PTFE-lined lumen. It also includes physical accessories (Tuohy-Borst Hemostasis Valve and Vessel Dilator). This is a hardware medical device.

Based on the provided information, this device is not an IVD (In Vitro Diagnostic).

Here's why:

  • Intended Use: The intended use is for the "introduction of interventional devices into the peripheral, coronary, and neuro vasculature." This describes a device used in vivo (within the body) for a procedural purpose, not for examining specimens in vitro (outside the body) to diagnose a condition.
  • Device Description: The description details a catheter designed to be inserted into blood vessels to facilitate other procedures. This aligns with an interventional medical device, not an IVD.
  • Lack of IVD Characteristics: There is no mention of analyzing biological specimens (blood, urine, tissue, etc.), reagents, or any other components typically associated with in vitro diagnostic testing.

Therefore, the AXS Infinity LS Plus Long Sheath is an interventional medical device, not an In Vitro Diagnostic.

Device Description:

The AXS Infinity LS Plus Long Sheath is a variable stiffness catheter that has a catheter shaft reinforced with a stainless-steel mixed coil design (single wind and cross coil wind). It has a radiopaque Platinum/Iridium marker band on the distal end. The distal 10 cm of the AXS Infinity LS Plus Long Sheath has a hydrophilic coating which reduces the insertion force and allows the catheter to traverse the vasculature more easily. The catheter has a maximum average outer diameter of 0.109", where no point is > 0.112" and a nominal inner diameter of 0.091". It is available in three working lengths: 70 cm, 80 cm, and 90 cm. The AXS Infinity LS Plus Long Sheath has a PTFElined lumen. The AXS Infinity LS Plus Long Sheath is inserted at a vascular access point to provide access to the target site and once in place, provides a reinforcing conduit for other intravascular devices. Accessories included with the device are a Tuohy-Borst Hemostasis Valve and a Vessel Dilator. The accessories are identical to those in the previous clearance (K172468). The AXS Infinity LS Plus Long Sheath is supplied sterile, non-pyrogenic, and intended for single use only.

Indications for Use

The AXS Infinity LS™ Plus Long Sheath is indicated for the introduction of interventional devices into the peripheral, coronary, and neuro vasculature.

Technological Characteristics and Product Feature Comparison

The AXS Infinity LS Plus Long Sheath is composed of a PTFE inner liner, a reinforcing stainless-steel single and cross-coil wind middle layer, and a polymer jacket outer layer. A polycarbonate Luer hub is bonded onto the proximal end. The device features segmented, progressively softer distal segments with a soft tip, designed to minimize vessel trauma, which contains a radiopaque platinum iridium marker band to provide visualization by fluoroscope. Stryker Neurovascular has demonstrated that the AXS Infinity LS Plus Long Sheath (modified) is substantially equivalent to the Predicate device (K172468), based on same or similar materials, same intended use, similar design and the same fundamental operating principles. A comparison of the Subject device with the Predicate device is summarized in Table 5-2, below.

Risk Assessment

A Risk Assessment of the AXS Infinity LS Plus Long Sheath with design changes has been conducted in accordance with EN ISO 14971:2012 Medical devices- Application of risk management to medical devices. Based on the similarity in design and identical intended use of the AXS Infinity LS Plus Long Sheath, the same risk and risk mitigation activities were applied. There were no changes in functionality. Additionally, a risk analysis was conducted at several points throughout the design process and documented throughout the process in updates to the DHF, and where necessary, updates to risk documentation. An impact assessment was also performed to analyze the effect of the proposed modifications to the existing AXS Infinity LS Plus Long

Sheath. Results of testing are appropriate for determining that the AXS Infinity LS Plus Long Sheath is substantially equivalent to the legally marketed Predicate device.

Summary of Non-Clinical Data

Testing was conducted for the specifications that were impacted by the changes to the AXS Infinity LS Plus Long Sheath: Proximal shaft material (coextrusion); mixed coil winding pattern and pitch; modifications to the wall thickness and lengths of different polymer sections along the catheter shaft; modification to the outer diameter and use of a different adhesive to secure the marker band. Summary descriptions of the testing, which substantiates the safe and effective performance of the subject device and its substantial equivalence to the Predicate device is provided below.
