#### Intended Use / Indications for Use
The Upstream GoBack Crossing Catheter is intended to be used in conjunction with steerable guidewires to access discrete regions of the peripheral vasculature. It may be used to facilitate placement and exchange of guidewires.
The Upstream GoBack Crossing Catheter is not intended for use in the coronary, cerebral or carotid vasculature.
# Device Description
The Upstream GoBack Crossing Catheter is a sterile, single lumen support catheter, that consists of a reinforced polyimide shaft with a stainless steel tip, and PTFE polymer coated nitinol hypotube inside the shaft. The nitinol tube has a pre-shaped lancet tip at the distal end and a hub at the proximal end for guidewire access. The nitinol tube can move at limited displacement inside the shaft, by moving a sliding knob in the catheter handle.
The Upstream GoBack Crossing Catheter is intended for use with 0.014" and 0.018" non-coated quidewires and the effective length of the catheter is 120 cm with an outer diameter of 1.4 mm.
{4}------------------------------------------------
# Comparison of Technological Characteristics
The GoBack Catheter, the OutBack catheter and the Wingman Crossing Catheter have very similar technological features. Each of the devices is a single-lumen, sterile, single-use catheter comprised of biocompatible materials. The GoBack Catheter, the OutBack catheter and the Wingman Crossing Catheter shafts are composed of braided polymer tubes of three layers - a middle layer composed of metal stainless steel wires, with an outer polymer jacket and an inner polymer liner. A slide-able flexible metal tube is located inside the shaft of all devices. Further, the GoBack Catheter, the predicate and reference devices all incorporate a distal lancet tip of the slide-able metal tube, and proximal female luer hub. The slide-able metal tubes are coated with PTFE or Teflon coating to permit smooth tracking of the metal tube inside the shaft.
Although there are minor differences between the GoBack Catheter and the predicate device, none of these differences raise new types of safety or effectiveness questions. The GoBack Catheter needle tip is curved with a maximal needle tip protrusion of 11 mm whereas the predicate device consists of a curved needle tip with a maximal tip protrusion of 8 mm. This difference does not raise new questions of safety or effectiveness as both devices consist of adequate device mechanisms for device needle navigation through the peripheral vasculature, which has been confirmed by bench testing.
The GoBack Catheter radiopague marker is mounted directly on the needle and serves to identify the needle tip location and needle curve direction. while the predicate's similar radiopaque marker is mounted on the catheter shaft and serves to identify only the needle curve direction. This minor technological difference does not raise new issues of safety or effectiveness because the key question of device detection using radiopaque markers during clinical procedures is the same for both the subject and predicate device.
The dimensions of the GoBack Catheter are within the range of dimensions of the predicate. The GoBack Catheter is 120 cm in length. The OutBack catheter length is 80 cm and 120 cm, while the Wingman Crossing Catheter is available in several length sizes, including 65 cm, 90 cm, 135 cm, and 150 cm. The outside diameter of the GoBack Catheter is 1.4 mm, the OutBack catheter is 2.0 mm, and the Wingman catheter has outside diameters of 1.3-1.5 mm. Thus, the dimensions of the GoBack Catheter do not raise new types of safety or effectiveness questions because the length and outside diameter of the GoBack Catheter are within the range of dimensions of the cleared predicate and reference devices.
Furthermore, all verification testing conducted with the GoBack Catheter demonstrates that the device meets its intended design and performance specifications, and that minor differences in technological features do not impact safety or effectiveness. Therefore, any minor technological differences do not raise new questions of safety or efficacy of the device and it satisfies the second criterion for substantial equivalence based on the technological characteristics compared to the predicate device.
# Performance Testing Summary
The following nonclinical performance testing has been conducted to support the substantial equivalence of the Upstream GoBack Crossing Catheter to its predicate device. In all instances, the Upstream GoBack Crossing Catheter functioned as intended.
- . Sterilization validation was established in accordance with ISO 11135 and EN 868-5.
- . Packaging integrity and accelerated aging studies were completed in accordance with ISO 11607-1, ISO 11607-2, ASTM F1980-07, and ASTM F1929.
{5}------------------------------------------------
- Biocompatibility of the patient-contacting components of the device was established in accordance with ISO 10993-1 and included cytotoxicity, sensitization, irritation/intracutaneous reactivity, systemic toxicity (acute), hemocompatibility (hemolysis and thromboresistance), pyrogenicity, and complement activation.
- . Functional bench testing was conducted on sterile devices (air leakage test, liquid leakage test, force at break test, surface test, catheter dimensions test, catheter delivery and kink testing, catheter torque testing, needle tip protrusion testing, marker movement test, torque at break test, bending to kink test, transfer of torsional force, needle penetration force catheter radio-opaque testing, corrosion testing, catheter hydration testing, catheter environmental testing, and packaging sealing testing).
In addition, a retrospective evaluation of 25 subjects was conducted based on clinical cases performed at Leipzig University Medical Center and at Bad-krozingen Heart-Center, both in Germany, to provide additional clinical data regarding the safety and technical success of the GoBack Catheter for recanalization of chronic total occlusion (CTO) in the iliac/femoropoptiteal arteries.
Study subjects were required to have claudication or critical limb ischemia (Rutherford Category 2-5) and a de novo or re-occluded CTO (99-100%) lesion in a native iliac/femoropopliteal artery. The indication for intervention in these cases included claudication and critical limb ischemia. In all cases, conventional recanalization could not be successfully achieved.
The primary safety endpoint was a composite rate of major adverse Endpoints events (MAES) related to the GoBack Catheter through 24 hours post index procedure including: death, perforation reguiring intervention and clinically significant peripheral embolism. The primary effectiveness endpoint was device technical success, defined as the placement of a guidewire in the true lumen distal to a CTO as confirmed by the angiography core lab.
Of the subjects enrolled, 20 of 25 (80%) were male. The average age was 67 ± 10 years (range: 39 -82). The average lesion length was 21 ± 12 cm (range: 4 – 55). Investigators achieved a 92% percent (23/25) technical success rate using the GoBack Catheter to cross CTOs in the iliac/femoropopliteal arteries. At 24 hours post procedure (pre-discharge), all patients experienced an improvement of at least one category in the Rutherford classification, a six-stage scale commonly used to assess the severity of symptoms associated with PAD. No device-related adverse event was seen during the procedures or at 24 hours post procedure. These results support the substantial equivalence of the GoBack Crossing Catheter
# Substantial Equivalence
The Upstream GoBack Crossing Catheter and the predicate device have the same intended use and very similar indications, technological characteristics and principles of operation. The minor technological differences between the Upstream GoBack Crossing Catheter and its predicate raise no new types of safety or effectiveness questions. Performance testing demonstrates that the Upstream GoBack Crossing Catheter performs as intended and meets all design specifications with respect to its mechanical and handling characteristics, and that its materials are biocompatible. Thus, the Upstream GoBack Crossing Catheter is substantially equivalent to the Cordis Outback Catheter predicate device.
