| | System (K202218). Although the Indications for Use statement of the subject device is not identical to the predicate device, the differences do not alter the intended therapeutic use of the device and do not affect the safety and effectiveness of the device relative to the predicate. Both the JETi HTS and predicate device have the same intended use: removal of thrombi or emboli from and infusion of fluids into the peripheral vasculature including DVT.

The technological principle for both the subject and predicate device is based on a clot fragmentation mechanism, which uses aspiration and a jet with fluid delivery features. Although JETi HTS and predicate device have different clot fragmentation mechanism and catheter size offering, the different technological characteristics between the subject device and predicate do not raise different questions of safety and effectiveness. |
| --- | --- |
| Summary on Non-Clinical Testing | Non-clinical testing was not required to support the update to the Indications for Use. The JETi HTS (K232458) is used as a reference device to account for differences in the technological features between the predicate ZelanteDVT Thrombectomy System and the JETi HTS. JETi HTS (K232458) is identical in design, technological, and performance characteristics to the subject device. |
| Summary on Clinical Testing | The JETi Registry collected real-world data on the safety, performance, and clinical benefits of the JETi HTS System for the treatment of thrombosis in the peripheral vasculature. It is a prospective, single-arm, multicenter study that registered 260 subjects treated for thrombosis in the peripheral vasculature from 27 sites in the United States (US) and Europe. Subjects were treated for arterial, venous, or arteriovenous thromboses and are followed for 12 months, with data collection at baseline, during the procedure, discharge, 30-day, and 12-month visits. This was a standard of care all-comers registry, and there were no restrictions on presenting thrombus location in the peripheral vasculature or onset of signs and symptoms.

A total of 116 registered subjects were treated for lower extremity (LE) DVT. Subject mean age was 56.6 ± 18.5 years, with the youngest subject being 18 and oldest subject being 85 years old. The majority, 55.2% (64/116), were under 65 years old. The split between male 50.0% (58/116) and female 50.0% (58/116) subjects was even. Of the analysis population, 50.9% (59/116) identified as Caucasian, 6.9% (8/116) identified as Black; 1.7% (2/116) identified as American Indian or Alaskan Native; 31.9% (37/116) of subjects declined to disclose or did not disclose their race information due to Europe’s |

Treatment strategy, including the use of adjunctive therapy, was per investigator’s discretion. The majority of patients in the registry (66.1% of limbs) were not treated with any adjunctive interventional device(s) (CDT or other thrombectomy device).

The primary effectiveness endpoint, defined as at least 75% reduction in modified Marder Score from pre-JETi venogram to final venogram, per core laboratory assessment, was achieved in 84.5% (93/110) limbs, with a one-sided 97.5% lower confidence limit of 76.4% comparing to a performance goal of 64% with a p value of < 0.0001. The primary effectiveness endpoint of the JETi Registry was met. Primary effectiveness endpoint was comparable when the JETi system was used with or without adjunctive interventional device(s); with at least 75% thrombus reduction achieved in 86.8% and 83.3% of limbs, respectively.

The primary safety endpoint, defined as the composite of JETi-related major adverse events up to 30 days post-JETi per CEC adjudication, was 1.7% (2/116) (95% CI, 0.21%, 6.09%). The rate of 1.7% (2/116) is less than the acceptance criterion of 10%. The primary safety endpoint of the JETi Registry was met.

Treated vessel patency and compressibility, Villalta post-thrombotic syndrome score, leg pain, and quality of life were all improved at 30 days. |
| --- | --- |
| Statement of Equivalence | The proposed changes to the Indications for Use, namely adding the specific use for DVT, is supported by the clinical data presented and thus, has been shown to not raise new or different questions of safety and effectiveness relative to the predicate, therefore, it can be concluded that the JETi HTS is substantially equivalent to the predicate device. |
