{7}------------------------------------------------
At a high level, the subject and predicate devices comprise the following same technological elements:
- . Both the subject and predicate device use a delivery catheter to place the aspiration device into the uterine cavity to remove material.
- Both the subject and predicate device employ a syringe to apply vacuum on the aspiration . device.
- . Both the subject and predicate device use similar materials in the construction of the catheter.
- . Both the subject device and predicate device utilize everting Membrane technology using the same materials, configuration, dimensions, and hydraulic principle for crossing the cervical canal.
- . Both the subject device and the predicate device have the same sterilization method, packaging construction and materials.
The following technological differences exist between the subject and predicate device:
- The subject device uses a 10cc syringe to apply vacuum suction to the Aspiration Device. The predicate device uses a 3cc syringe to apply vacuum suction.
- . The subject device utilizes a Blue Pinch Clamp and a White Pinch Clamp as one-way valves (on/off). The predicate device utilizes a Blue Stopcock and White Stopcock as one-way valves in the same locations on the catheter. The stopcock and pinch clamp share the same function and performance characteristics.
- . The subject device utilizes a 10cc syringe to infuse saline trough the catheter and into the uterine cavity.
{8}------------------------------------------------
The differences in technology do not raise different questions of safety and effectiveness, as both the subject and predicate device operate to transfer fluid/tissue through the catheter via manual pressure.
# VIII. PERFORMANCE DATA
The following performance data were provided in support of the substantial equivalence determination.
## Bench Testing
Physical bench testing confirmed that the CrossGlide™ ETS Plus performs according to the product specifications. Device evaluation consisted of physical and functional testing performed pursuant to test protocols that were used to support clearance of the predicate or reference device. Mechanical testing, including tensile and pressurization testing, was conducted to determine if the pinch clamps could operate during expected functional conditions. Additional pressurization testing was conducted to determine if the use of a 10cc syringe can maintain adequate negative pressure required for sample collection. The subject device successfully passed all functional bench testing (i.e., met predefined acceptance criteria).
### Biocompatibility testing
The subject device utilizes identical materials and manufacturing as the predicate device. Therefore, biocompatibility testing on the predicate device, which was conducted according to ISO 10993-1 "Biological Evaluation of Medical Devices" and FDA's guidance "Use of International Standard ISO 10993-1", final document issued on June 16, 2016 can be leveraged to support the biocompatibility of the subject device. Testing included the following with passing results: 1) Cytotoxicity, 2) Vaginal Irritation, and 3) Sensitization.
## Sterilization Validation
The subject device utilizes the same product design and packaging as the predicate device. The predicate device was evaluated for adoption into the current ethylene oxide (EO) sterilization cycle of the contract sterilizer. The evaluation process was performed utilizing the AAMI Guidance contained in TIR28:2016 Product adoption and process equivalence for ethylene oxide sterilization. The EO Sterilization Cycle was originally validated in 2016, using the overkill method, in accordance with ANSI/AAMI/ISO 11135:2014. The results and conclusion of this evaluation confirmed that the subject device could be adopted into the previously validated cycle.
#### Packaging, Shipping Validation, and Shelf-Life
The subject device utilizes the same product design and packaging as the predicate device. Packaging and shipping validation studies were conducted pursuant to the applicable ASTM guidelines (ASTM F88/F88M - 15 "Standard Test Method for Seal Strength of Flexible Barrier
{9}------------------------------------------------
Materials"; and, ASTM F 2096-11 "Standard Test Methods for Detecting Gross Leaks in Packaging by Internal Pressurization (Bubble leaks)"; ASTM D4169-16 Standard Practice for Performance Testing of Shipping Containers and Systems, using Distribution Cycle 13. The shelf-life is supported by packaging and performance tests conducted on samples exposed to accelerated aging conditions pursuant to ASTM F1980 - 16 "Standard Guide for Accelerated Aging of Sterile Barrier Systems for Medical Devices".
## IX: CONCLUSIONS
The CrossGlide™ ETS Plus Sonohysterography and Endometrial Tissue Sampler has the same intended use as the predicate device. There are differences in the indications for use statements for the subject and predicate devices. The differences between the subject and predicate Indications for Use do not alter the intended use of the device. In addition, the subject device has the similar technological characteristics as the predicate device and the differences do not raise different questions of safety and effectiveness. Finally, the submitted testing demonstrates that the subject device is as safe, as effective, and performs as well as the predicate device. Therefore, the CrossGlide™ ETS Plus is substantially equivalent to the cleared predicate device.
