No
The device description clearly details a physical guide wire constructed from materials like stainless steel and coated with Microglide® and PTFE. It undergoes bench testing for physical properties like tensile strength and torsional strength, and in vivo testing in animals, all indicative of a hardware device. There is no mention of software as the primary or sole component.
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 a steerable wire intended to facilitate the placement of other medical devices (balloon catheters, atherectomy devices, stent devices) within the body during percutaneous procedures.
- Device Description: The description details the physical construction and coatings of a guide wire designed for navigating within the vascular system.
- Lack of In Vitro Activity: There is no mention of the device being used to examine specimens derived from the human body in vitro (outside the body) to provide information for diagnosis, monitoring, or compatibility testing.
IVD devices are specifically designed to perform tests on biological samples (like blood, urine, tissue) to provide diagnostic or other medical information. This guide wire is an invasive surgical tool used to assist in procedures performed directly on the patient's body.

Device Description
The ACS HI-TORQUE BALANCE MIDDLEWEIGHT™ Guide Wire is a steerable guide wire intended to facilitate placement of balloon dilatation catheters during Percutaneous Transluminal Coronary Angioplasty (PTCA) and Percutaneous Transluminal Angioplasty (PTA). The wire is also intended to facilitate the placement of equipment, such as atherectomy and compatible stent devices, during other diagnostic and therapeutic intravascular procedures. It is not intended for use in the cerebral vasculature.
The proximal and distal portions of the guide wire are constructed from a core assembly. A series of tapers and flats, which reduce the diameter of the core wire distally, yields the desired tip flexibility. The ACS HI-TORQUE BALANCE MIDDLEWEIGHT™ Guide Wire is coated with Microglide® from 40cm to 3cm back from the distal tip, while the remaining portion is coated with polytetrafluoroethylene (PTFE). Both coatings are intended to reduce friction for improved movement of the wire within the catheter.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
Bench Testing:
The tensile strengths of the guide wire distal tip and hypotube junction were determined by pull tests. These tests demonstrated that the ACS HI-TORQUE BALANCE MIDDLEWEIGHT™ Guide Wire has adequate tensile strength.
The torsional strength of the distal tip and hypotube junction were determined by turns-to-failure tests. This test showed that the ACS HI-TORQUE BALANCE MIDDLEWEIGHT™ Guide Wire has adequate torsional tip strength.
The correlation between rotation of the proximal end and the corresponding rotation of the distal end of the guide wire was determined by the rotational accuracy test. This test showed that the ACS HI-TORQUE BALANCE MIDDLEWEIGHT™ Guide Wire has an adequate torque response.
The tip flexibility testing demonstrated that tip flexibility of the ACS HI-TORQUE BALANCE MIDDLEWEIGHT™ Guide Wire has acceptable tip flexibility.
In vivo Testing:
An animal study was completed to evaluate and compare the performance of the ACS HI-TORQUE BALANCE MIDDLEWEIGHT™ Guide Wire to that of the ACS Hi-Torque Floppy Xtra Support® Guide Wire (K913353, October 23, 1991) when used in combination with the Johnson and Johnson (JJIS) Stent Delivery System, the DVI AtheroCath-GTO Atherectomy Catheter, and with the CVIS UltraCrossIntravascular ultrasound catheter.
The results of these studies show that the ACS HI-TORQUE BALANCE MIDDLEWEIGHT™ Guide Wire performs as well as or better than the ACS Hi-Torque Floppy Xtra Support® Guide Wire in the majority of the performance parameters when used to facilitate the placement of equipment, such as atherectomy and compatible stent devices, and during other diagnostic and therapeutic intravascular procedures.

3. Performance Standards:
Performance standards have not been established under Section 514 of the Federal Food, Drug, and Cosmetic Act for vascular guide wires.
Device Description: 4.
The ACS HI-TORQUE BALANCE MIDDLEWEIGHT™ Guide Wire is a steerable guide wire intended to facilitate placement of balloon dilatation catheters during Percutaneous Transluminal Coronary Angioplasty (PTCA) and Percutaneous Transluminal Angioplasty (PTA). The wire is also intended to facilitate the placement of equipment, such as atherectomy and compatible stent devices, during other diagnostic and therapeutic intravascular procedures. It is not intended for use in the cerebral vasculature.
The proximal and distal portions of the guide wire are constructed from a core assembly. A series of tapers and flats, which reduce the diameter of the core wire distally, yields the desired tip flexibility. The ACS HI-TORQUE BALANCE MIDDLEWEIGHT™ Guide Wire is coated with Microglide® from 40cm to 3cm back from the distal tip, while the remaining portion is coated with polytetrafluoroethylene (PTFE). Both coatings are intended to reduce friction for improved movement of the wire within the catheter.
5. Summary of Substantial Equivalence:
A comparison of the ACS HI-TORQUE BALANCE MIDDLEWEIGHT™ Guide Wire to the predicate ACS HI-TORQUE BALANCE® Guide Wire (K925381, approved February 12, 1993), indicates that the new guide wire is substantially equivalent to the predicate guide wire with regard to its materials, design, and functional properties, and packaging.
The ACS BALANCE MIDDLEWEIGHT™ Guide Wire is a steerable guide wire intended to facilitate placement of balloon dilatation catheters during Percutaneous Transluminal Coronary Angioplasty (PTCA) and Percutaneous

Transluminal Angioplasty (PTA). The wire is also intended to facilitate the placement of equipment, such as atherectomy and compatible stent devices, during other diagnostic and therapeutic intravascular procedures. It is not intended for use in the cerebral vasculature. The ACS HI-TORQUE BALANCE MIDDLEWEIGHT™ Guide Wire is substantially equivalent to the ACS Hi-Torque Floppy Xtra Support® Guide Wire (K913353, approved October 23, 1991) with regard to its intended use.
The design of the new ACS BALANCE MIDDLEWEIGHT" Guide Wire is constructed from a stainless steel core wire. Like the predicate 0.014" HI-TORQUE BALANCE® guide wire, the new guide wire design includes a series of tapers and flats which reduce the diameter of the core wire distally, yielding the desired tip flexibility. Unlike the 0.014" HI-TORQUE BALANCE® Guide Wire, the ACS HI-TORQUE BALANCE MIDDLEWEIGHT™ wire diameters and tapers along the length of the distal portion of the guide wire have been modified to yield the desired support over the distal 30 centimeters of the wire. This modification involves no new materials or processes in comparison to the predicate wire, and has no effect on the distal tip of the guide wire. Therefore, the tapers and diameters positioned at different locations proximal to the tip cannot significantly impact the safety or effectiveness of the guide wire.
ર્. Testing Data:
Bench Testing:
The tensile strengths of the guide wire distal tip and hypotube junction were determined by pull tests. These tests demonstrated that the ACS HI-TORQUE BALANCE MIDDLEWEIGHT™ Guide Wire has adequate tensile strength.
The torsional strength of the distal tip and hypotube junction were determined by turns-to-failure tests. This test showed that the ACS HI-TORQUE BALANCE MIDDLEWEIGHT™ Guide Wire has adequate torsional tip strength.
The correlation between rotation of the proximal end and the corresponding rotation of the distal end of the guide wire was determined by the rotational accuracy test. This test showed that the ACS HI-TORQUE BALANCE MIDDLEWEIGHT™ Guide Wire has an adequate torque response.
The tip flexibility testing demonstrated that tip flexibility of the ACS HI-TORQUE BALANCE MIDDLEWEIGHT™ Guide Wire has acceptable tip flexibility.

In vivo Testing:
An animal study was completed to evaluate and compare the performance of the ACS HI-TORQUE BALANCE MIDDLEWEIGHT™ Guide Wire to that of the ACS Hi-Torque Floppy Xtra Support® Guide Wire (K913353, October 23, 1991) when used in combination with the Johnson and Johnson (JJIS) Stent Delivery System, the DVI AtheroCath-GTO Atherectomy Catheter, and with the CVIS UltraCrossIntravascular ultrasound catheter.
The results of these studies show that the ACS HI-TORQUE BALANCE MIDDLEWEIGHT™ Guide Wire performs as well as or better than the ACS Hi-Torque Floppy Xtra Support® Guide Wire in the majority of the performance parameters when used to facilitate the placement of equipment, such as atherectomy and compatible stent devices, and during other diagnostic and therapeutic intravascular procedures.
Biocompatibility:
Since the materials for the ACS HI-TORQUE BALANCE MIDDLEWEIGHT™ Guide Wire are identical to those of the predicate 0.014" HI-TORQUE BALANCE® Guide Wire, the biocompatibility data from the predicate device were used to demonstrate that the materials and processes utilized in the new guide wire are biocompatible for short term use within the vascular system.
7. Sterilization:
The ACS BALANCE MIDDLEWEIGHT™ Guide Wire is sterilized by the same methods and following the same parameters as those used for the predicate 0.014" HI-TORQUE Balance@ Guide Wire (K925381, approved February 12, 1993),
