### 7.1 Device Description (HI-TOROUE PROGRESS)

The HI-TOROUE PROGRESS Guide Wire (K091825, cleared Sept. 25, 2009) is an existing family of guide wires, designed to provide improved torque response and crossing while maintaining tactile feedback in stenotic vessels. The subject wire is a core to tip design, where the core material runs through the entire length of the wire. This family of guide wires has a maximum diameter of 0.0140" with a stainless steel core and is provided in 190cm extendable and 300cm exchange lengths. The distal core segment of the PROGRESS guide wire family is offered in 5 configurations: PROGRESS 40. PROGRESS 80, PROGRESS 120, PROGRESS 140T and PROGRESS 200T. Each configuration is identical in design except for those design features that impact tip stiffness.

### 7.2 Device Description (HI-TOROUE PILOT)

The HI-TOROUE PILOT Guide Wire (K030549/K101116, originally cleared Mav 14, 2003) is an existing family of guide wires constructed using a 304V stainless steel core. HI-TORQUE PILOT Guide Wires have a maximum diameter of 0.0140" and are available in 190cm extendable lengths and a 300 cm exchange length. There are three HI-TORQUE PILOT™ Guide Wire designs with varying tip stiffness (i.e., HI-TORQUE PILOT™ 50, HI-TORQUE PILOT™ 150, and HI-TOROUE PILOT™ 200 Guide Wires). The distal segment of the guide wire includes a series of tapered grinds and a flat section, which reduce the diameter and stiffness of the distal core, thus yielding the desired flexibility and performance.

#### 7.3 Indication for Use (HI-TOROUE PROGRESS and HI-TOROUE PILOT)

Intended to facilitate the delivery of catheter-based interventional devices during percutaneous transluminal coronary angioplasty (PTCA) and percutaneous transluminal angioplasty (PTA). This guide wire may be used with compatible stent devices during therapeutic procedures. The guide wire may be used to reach and cross a target lesion. provide a pathway within the vessel structure, facilitate the substitution of one diagnostic or interventional device for another, and to distinguish the vasculature. This guide wire may also be used to cross or assist in crossing de novo chronic total coronary occlusions (CTO).

#### 7.4 Technological Characteristics

There have been no physical changes to the subject devices as compared to the currently marketed predicate devices except for a change in indication and related clinical information provided in the IFU and labeling. Comparisons of the technological characteristics such as product performance, design, and intended use between the subject and predicate devices show that they are substantially equivalent.

{2}------------------------------------------------

### 7.5 In Vitro Bench, Biocompatibility, Packaging and Sterilization Testing

There have been no physical changes to the subject devices as compared to the predicate devices except for a change in indication statement and related clinical information provided in the IFU and labeling. Comparisons of in-vitro bench, biocompatibility, packaging, and sterilization testing are not necessary. The subject and predicate devices are identical and in-vitro bench testing, biocompatibility, packaging and sterilization for the subject devices are therefore substantially equivalent to their respective predicate devices.

### 7.6 EXPERT CTO Guidewire Clinical Trial Summary

### Objectives

The primary objectives of this trial are to:

- assess the safety and effectiveness of the HI-TORQUE (HT) PROGRESS and HT . PILOT guide wires in recanalization of chronic total occlusions and
- assess the safety and effectiveness of the MINI TREK Coronary Dilatation . Catheter in predilatation of chronic total occlusions.
- assess the safety and effectiveness of the XIENCE V, XIENCE nano, and . XIENCE PRIME Everolimus Eluting Coronary Stent Systems for the treatment of chronic total coronary occlusions.

Although the guidewire and predilatation portions of the EXPERT CTO clinical trial are complete, the longer term safety and effectiveness results of the XIENCE V and XIENCE PRIME stent systems in the treatment of chronic total occlusions is ongoine. The MINI TREK predilatation results and XIENCE V and XIENCE PRIME results will be reported separately.

## Trial Design

The EXPERT CTO is a prospective, multi-center, single-arm study. Approximately 250 subjects with signs and/or symptoms considered typical of ischemic heart disease attributed to a CTO are expected to be enrolled. Subjects will undergo elective, attempted CTO percutaneous revascularization.

For the initial 138 subjects enrolled. HT PROGRESS or HT PILOT guide wires (the study guidwires) were used in each case. Other, non-study guidewires may also have been used in each case at the discretion of the physician. Successful guide wire crossing was defined as confirmation of the presence of a guide wire in the distal true lumen. Guide wire subjects were followed through hospital discharge. The target lesions were predilated using a standard angioplasty balloon. For at least the initial 60 subjects with successful guide wire crossing, identified as confirmation of the guide wire in the distal true lumen, the MINI TREK Coronary Dilatation Catheter was to be used for the first predilatation attempt. The XIENCE V and/or XIENCE PRIME stents were to be used in all subjects

{3}------------------------------------------------

for whom recanalization and predilatation of the target lesion was completed. Stent subjects are to be followed through 5 years with follow-up at 30 days, 6 months, 1 year, and annually thereafter through 5-years.

#### 7.7 -Results

### Primary Endpoint Analysis

The primary endpoint of successful recanalization of the CTO was achieved in 79.0% (109/138) of the subjects with a lower one-sided 95% confidence interval (CI) of 72.8%. The individual criteria for successful recanalization included: confirmation of placement of any guide wire in the distal true lumen in 89.9% (124/138) of the subjects and absence of in-hospital MACE (per ARC MI definition) in 89.1% (123/138) of the subjects.

Because the lower one-sided 95% Cl is above the protocol-specified performance goal of 62.5% (p<0.0001), the study guide wire is considered to have successfully met its endpoint. Refer to Table 7-2

| | Guide Wire<br>Success | Two-sided<br>95% CI | Performance<br>Goal | Lower<br>Bound of<br>one-sided<br>95% CI | P-value |
|-------------------------------------------------------------------------|-----------------------|---------------------|---------------------|------------------------------------------|---------|
| Guide Wire-related Endpoint | 79.0% (109/138) | [71.2%,85.5%] | 62.50% | 72.8% | <0.0001 |
| Confirmation of placement of any<br>guide wire in the distal true lumen | 89.9% (124/138) | [83.6%,94.3%] | -- | -- | -- |
| Absence of in-hospital MACE** | 89.1% (123/138) | [82.7%,93.8%] | -- | -- | -- |

### Table 7-2 Primary Endpoint Results – All Guidewires

** Based on ARC MI.

To allow for a more meaningful comparison to literature, an alternate analysis of the primary endpoint was performed. The successful recanalization rate was calculated using the MI per protocol definition for the second component of absence of in-hospital MACE. , Successful recanalization of the CTO was achieved in 87.7% (121/138) of the subjects with a lower one-sided 95% CI of 82.3%. Table 7-3 shows the results of the alternate analysis of the primary endpoint. The individual criteria for successful recanalization included: confirmation of placement of the guide wire in the distal true lumen in 89.9% (124/138) of the subjects and absence of in-hospital MACE (per protocol MI definition) in 97.8% (135/138) of the subjects. The lower bound of the one-sided 95% CI of the primary endpoint in the secondary analysis is approximately 20% above the protocolspecified performance goal of 62.5% (p<0.0001).

| Absence of in-hospital MACE** | 97.8% (135/138) | [93.8%,99.5%] |

#### 7.8 Clinical Summary Conclusion

The EXPERT CTO clinical trial and results demonstrate that the study guide wires, HI-TORQUE PROGRESS and HI-TORQUE PILOT families, were successfully used to treat chronic total coronary occlusions and that the primary and secondary endpoints of the guide wire portion of the study were met, and therefore support a CTO indication for these wires. No new safety or effectiveness issues were raised during the testing program and, therefore, these devices may be considered substantially equivalent to the predicate devices.
