Intended Use
This guide wire is intended to be used in the neuro vasculature to facilitate the placement and exchange of therapeutic devices such as cerebral catheters during intravascular therapy. This guide wire is intended for use only in the neuro vasculature.
Device Description
The ASAHI CHIKAI Black 14 Soft Tip neurovascular guide wire is a steerable guide wire with a maximum diameter of 0.014 inches (0.36mm) and length of 200cm. The quide wire is constructed from a stainless steel core wire with platinum-nickel and stainless steel coils. The coil assembly consists of an inner coil and an outer coil, and the coil assembly is soldered to the core wire. The coil assembly construction is similar to that of the 510(k) cleared ASAHI CHIKAI black neurovascular guide wire (K141751). The distal end of the guide wire has a radiopaque tip to achieve visibility. A hydrophilic coating is applied to the distal portion of the guidewire. This change introduces a soft tip version of the round curve tip configuration.
More Information

No
The device description and performance studies focus on the physical properties and mechanical performance of a guide wire, with no mention of AI or ML.

No
The device, a guide wire, is intended to facilitate the placement and exchange of therapeutic devices, not to be a therapeutic device itself.

No

Explanation: The device is described as a guide wire intended to facilitate the placement and exchange of therapeutic devices. Its function is to guide other medical instruments, not to diagnose a condition or disease.

No

The device description clearly states it is a physical guide wire constructed from stainless steel and other materials, and the performance studies involve bench testing of physical properties like tensile strength and torque.

No, this device is not an IVD (In Vitro Diagnostic).

Here's why:

  • Intended Use: The intended use clearly states that the guide wire is used in the neuro vasculature to facilitate the placement and exchange of therapeutic devices during intravascular therapy. This describes a device used within the body for a medical procedure, not a device used to test samples outside the body.
  • Device Description: The description details the physical construction of a guide wire designed to be inserted into blood vessels.
  • Performance Studies: The performance studies focus on physical properties like tensile strength, torque strength, torqueability, and tip flexibility, as well as simulated clinical use within a model. These are all relevant to a device used in a medical procedure, not an IVD.
  • Lack of IVD Characteristics: There is no mention of analyzing biological samples (blood, urine, tissue, etc.), detecting specific analytes, or providing diagnostic information based on laboratory testing.

In summary, this device is an invasive medical device used for a therapeutic procedure, not an in vitro diagnostic device.

Summary of Performance Studies

The substantial equivalence of the ASAHI CHIKAI black line extension was evaluated in bench testing that followed the recommendations in the FDA guidance document: Coronary and Cerebrovascular Guidewire Guidance. Only those tests impacted by the device modifications were repeated.

  • Tensile Strength: To determine maximum allowable tensile load between connections, guide wire is fixed in the Tensile Testing Machine and pulled until failure. All test articles met established acceptance criteria. Acceptance criteria determined by evaluation of predicate devices and ASAHI's established tensile strength specifications.
  • Torque Strength: To determine torque strength, distal end is inserted & advanced through simulated model. Distal tip is held stationary while proximal end is rotated until failure. All test articles met established acceptance criteria. Acceptance criteria determined by evaluation of predicate devices and ASAHI's established torque strength specifications.
  • Torqueability: To determine torque response, guidewire is inserted through catheter & into Rotational Response model. Proximal end is rotated and the torque response at distal end is measured. All test articles met the acceptance criteria. Acceptance criteria determined by evaluation of predicate devices and ASAHI's established torqueability specifications.
  • Tip Flexibility: To determine flexibility of the distal end, the force to deflect the guide wire is measured by a force analyzer attached to a load cell. All test articles met established Tip Flexibility acceptance criteria. Acceptance criteria determined by evaluation of predicate devices and ASAHI's established tip flexibility specifications.
  • Bench (Simulated) Testing: To simulate clinical use, guidewire is inserted through guide catheter placed in simulated model and advanced to target area. Microcatheter is inserted over guidewire & advanced to target cerebral artery multiple times. Test results on all test articles confirmed guide wire performance. Guidewire reached target area and microcatheter was successfully advanced over guidewire to target site.

T acceptance criteria and performed similarly to the predicate device. Performance data demonstrate that the device functions as intended, and has a safety and effectiveness profile that is similar to the predicate device.

BIOCOMPATIBILITY:

The ASAHI CHIKAI Black 14 Soft Tip was compared to the predicate device. Based on the identical materials and manufacturing process used in the subject device to its predicate, the biocompatibility of the ASAHI CHIKAI Black 14 Soft Tip was verified to be the same as those of the predicate.

Conclusion:

The ASAHI CHIKAI Black 14 Soft Tip has identical intended use and the same or similar technological characteristics such as components, design, materials, sterilization method, shelf life and operating principles as the predicate devices. Performance data demonstrates that the device functions as intended. Therefore, the ASAHI CHIKAI Black 14 Soft Tip is substantially equivalent to the predicate device.
