Intended Use
Pre-Formed Guidewires are intended to facilitate the introduction and placement of interventional devices within the chambers of the heart, including those used within transcatheter aortic valve procedures.
Device Story
Pre-Formed Guidewire is a 0.035" diameter, 260-300cm long stainless steel wire used to facilitate placement of interventional devices in heart chambers. Device consists of inner stainless steel core and outer stainless steel coil coated in green PTFE; distal end features double-curve shape. Used by clinicians in interventional cardiology settings. Guidewire acts as a track for delivery of interventional devices, such as those for transcatheter aortic valve procedures. Benefits include improved navigation and placement of interventional tools within cardiac chambers. Device is not for use in coronary or cerebrovascular arteries.
Clinical Evidence
Bench testing and a GLP animal study were performed. Bench testing included dimensional, tensile strength, tip flexibility, catheter compatibility, packaging, tip shape retention, particulate, visual, fracture, flex, corrosion resistance, and linear stiffness tests. A GLP animal study evaluated safety and performance compared to the predicate. No new biocompatibility testing was required as materials remained unchanged. Results demonstrate the device is as safe and effective as the predicate.
Technological Characteristics
Materials: Stainless steel (ASTM A313) core and coil; coil coated in green PTFE. Dimensions: 0.035" diameter, 260-300cm length. Tip: Double-curve shape. Standards: ISO 10993, ISO 11070, ISO 11135, ISO 11138. Non-powered, mechanical device.
Indications for Use
Indicated for facilitating introduction and placement of interventional devices within heart chambers, including transcatheter aortic valve procedures. Contraindicated for use in cerebrovasculature or coronary arteries.
Regulatory Classification
Identification
A catheter guide wire is a coiled wire that is designed to fit inside a percutaneous catheter for the purpose of directing the catheter through a blood vessel.
Special Controls
*Classification.* Class II (special controls). The device, when it is a torque device that is manually operated, non-patient contacting, and intended to manipulate non-cerebral vascular guide wires, is exempt from the premarket notification procedures in subpart E of part 807 of this chapter subject to the limitations in § 870.9.

#### DEVICE DESCRIPTION 2.6
The 0.035" diameter, 260-300cm length guidewire is composed of two primary wire components: a core and a coil. Both components are manufactured from Stainless Steel per ASTM A313. The core wire is a stainless steel wire which forms the inner body of the guidewire. The coil component is the guidewire's outer layer and is a stainless steel wire coated in Green Polytetrafluoroethylene (PTFE), The coil and the core components are welded together on the distal and proximal ends, forming the guidewire. The distal ends are shaped into a double-curve. The following table shows the characteristics of the product family:

#### QUALITY SYSTEM CONTROL 2.11
### DESIGN CONTROLS
LRM is in conformance with the design control procedure requirements as specified in 21 CFR Part 820.30. Risk analysis was completed by means of a Failure Mode and Effects Analysis and all verification and validation activities resulted in the ability to demonstrate that the predetermined acceptance criteria were met.
### MATERIALS / SUPPLIER / PRODUCT / PROCESS CONTROLS
LRM has formal quality systems in placed to assure that each product manufactured remains equivalent to the predicate products, and that the changes will not have an adverse effect on safety or effective use of the product. The quality systems include Engineering Change Order Review, Material Qualification, Supplier Qualification, Product Qualification, and Process Qualification. These controls are applied to each product size / group.
#### 2.12 QUALIFICATION TESTING
The conclusions drawn from bench testing and biocompatibility testing demonstrate compliance with the design input summary which shows the device is at least as safe and effective as the current legally marketed device.
### BENCH TESTING
In order to demonstrate equivalence of the guidewire, Lake Region Medical performed bench testing to establish requirements. Test devices were manufactured and inspected according to established requirements for visual/tactile, dimensional and mechanical attributes. The devices were then subjected to the following test methods to show the devices comply with the design input summary:
- Dimensional -
- -FDA Tensile Strength
- -FDA Tip Flexibility
- -FDA Catheter Compatibility
- -Packaging Study
- -Tip Shape Retention
- -Particulate
- ISO Visual "
- -ISO Fracture
- -ISO Flex
- -ISO Corrosion Resistance
- -Linear Stiffness
## BIOCOMPATIBILITY TESTING
There were no changes to materials used in the design or manufacture of the Pre-Formed guidewire family; therefore, no additional biocompatibility tests were completed.
### ANIMAL STUDY
A GLP Animal study was completed to evaluate safety and performance of the guidewire compared to the currently marketed device. The study shows the guidewires are substantially equivalent to the legally marketed device.
#### 2.13 CHANGES FROM PREDICATE DEVICE
- Additional tip shape, Extra Small -
- -Distal core grind diameter minimum made larger
#### 2.14 SUBSTANTIAL EQUIVALENCE DATA
The changes included in this 510(k) for the Pre-Formed guidewire family do not change the indications for use of the Mandrel guidewires and is not a change to the fundamental scientific technology. The information summarized above shows the device will perform as well as the previously marketed device.
