Intended Use
The Distal Access Catheter is indicated for general intravascular use, including the neuro and peripheral vasculature. It can be used to facilitate introduction of diagnostic agents or therapeutic devices. It is not intended for use in coronary arteries.
Device Description
The Distal Access Catheter consists of a catheter and accessories (hemostatic valve, introducer sheath, and a shaping mandrel). The catheter is a single-lumen, flexible catheter designed with coil and braid reinforcement. The distal segment is steamshapeable, and a hydrophilic coating is applied for navigation of the catheter through the vasculature. The radiopaque marker is located at the distal end of the catheter for visualization under fluoroscopy. The catheter body is constructed with a stainless-steel coil (less 2 cm of the catheter length) over the inner lumen liner comprised of polytetrafluoroethylene (PTFE). To provide additional shaft support, a stainless-steel wire braiding has been added over the stainless-steel coil from the proximal end to distal end. A platinum/iridium alloy radiopaque marker band is located at the distal tip of the catheter. An outer layer of varying durometers and lengths of polyamide (PA), polyether block amide (Pebax) and polyurethane (PU) covers the entire catheter body from proximal to distal end, respectively. A hub (PC) is attached to the proximal end of the catheter. A strain relief made from polyether block amide (Pebax) is placed at the proximal end of the catheter and distal end of the hub. The hub-strain relief provides for the kink resistance for the proximal end. A luer fitting on the catheter hub is used for the attachment of accessories. The outer surface of the catheter (distal 60 cm) is coated with a hydrophilic coating to reduce friction during navigation in the vasculature. A shaping mandrel (stainless steel, 80 mm in length) is provided with the catheter to be used by the physician for tip shaping. An introducer sheath (PTFE) is included to facilitate the introduction of the catheter into guide catheters during clinical use. A hemostatic valve is used to connect to the proximal section of the catheter. The Distal Access Catheter is provided sterile and for single use only. The catheter is placed in a dispenser tube (HDPE) and is placed on a packaging card (HDPE) that is provided in a sterile barrier PET/PE film and Tyvek pouch and placed in a carton box.
More Information

No reference devices were used in this submission.

No
The device description focuses on the physical components and materials of a catheter and its accessories. There is no mention of software, algorithms, or any capabilities that would suggest the use of AI or ML. The "Mentions AI, DNN, or ML" section also explicitly states "Not Found".

No.
The device facilitates the introduction of diagnostic agents or therapeutic devices but is not itself a therapeutic device.

No

The device is a Distal Access Catheter, used to facilitate the introduction of diagnostic agents or therapeutic devices. It is a tool for accessing anatomical sites, not a diagnostic device itself.

No

The device description clearly details physical components such as a catheter, introducer sheath, hemostatic valve, and shaping mandrel, all made of various materials. It also describes manufacturing processes and packaging, indicating it is a physical medical device, not software-only.

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

Here's why:

  • Intended Use: The intended use clearly states that the device is for "general intravascular use, including the neuro and peripheral vasculature." It is used to "facilitate introduction of diagnostic agents or therapeutic devices." This describes a device used within the body for procedural purposes, not for testing samples outside the body.
  • Device Description: The description details a physical catheter designed for insertion into blood vessels. It describes components like a lumen, reinforcement, coating, and radiopaque markers, all consistent with an invasive medical device.
  • Lack of IVD Characteristics: There is no mention of the device being used to analyze biological samples (blood, urine, tissue, etc.) or to provide diagnostic information based on such analysis. The device's function is mechanical and procedural.

IVD devices are specifically designed to perform tests on samples taken from the human body to provide information for diagnosis, monitoring, or screening. This device does not fit that description.

IV. DEVICE DESCRIPTION

The Distal Access Catheter consists of a catheter and accessories (hemostatic valve, introducer sheath, and a shaping mandrel). The catheter is a single-lumen, flexible catheter designed with coil and braid reinforcement. The distal segment is steamshapeable, and a hydrophilic coating is applied for navigation of the catheter through the vasculature. The radiopaque marker is located at the distal end of the catheter for visualization under fluoroscopy.

The catheter body is constructed with a stainless-steel coil (less 2 cm of the catheter length) over the inner lumen liner comprised of polytetrafluoroethylene (PTFE). To provide additional shaft support, a stainless-steel wire braiding has been added over the stainless-steel coil from the proximal end to distal end. A platinum/iridium alloy radiopaque marker band is located at the distal tip of the catheter. An outer layer of varying durometers and lengths of polyamide (PA), polyether block amide (Pebax) and polyurethane (PU) covers the entire catheter body from proximal to distal end, respectively.

A hub (PC) is attached to the proximal end of the catheter. A strain relief made from polyether block amide (Pebax) is placed at the proximal end of the catheter and distal

4

end of the hub. The hub-strain relief provides for the kink resistance for the proximal end. A luer fitting on the catheter hub is used for the attachment of accessories.

The outer surface of the catheter (distal 60 cm) is coated with a hydrophilic coating to reduce friction during navigation in the vasculature.

A shaping mandrel (stainless steel, 80 mm in length) is provided with the catheter to be used by the physician for tip shaping. An introducer sheath (PTFE) is included to facilitate the introduction of the catheter into guide catheters during clinical use. A hemostatic valve is used to connect to the proximal section of the catheter.

The Distal Access Catheter is provided sterile and for single use only. The catheter is placed in a dispenser tube (HDPE) and is placed on a packaging card (HDPE) that is provided in a sterile barrier PET/PE film and Tyvek pouch and placed in a carton box.

V. INDICATIONS FOR USE

The Distal Access Catheter is indicated for general intravascular use, including the neuro and peripheral vasculature. It can be used to facilitate introduction of diagnostic agents or therapeutic devices. It is not intended for use in coronary arteries.

VIII. CONCLUSIONS

The data presented in this submission demonstrate the technological similarity and substantial equivalence of the Distal Access Catheter when compared with the predicate devices SOFIA PLUS/Distal Access Catheter(K150366) and SOFIA Distal Access Catheter (K131482, K142014).

The subject and predicate devices,

  • . have the same indications for use,
  • . use the same operating principle,
  • . incorporate the same basic design,
  • . are packaged and sterilized using similar materials and processes.

In summary, the Distal Access Catheter described in this submission is substantially equivalent to the predicate devices.
