This study aimed to examine the efficacy, safety, and efficiency of the Tenzing 7 delivery catheter to deliver therapeutic devices in aspiration mechanical thrombectomy for acute ischemic strokes using clinical experience from multiple institutions.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec xml:lang=\"en\">\n            <jats:title>Methods<\/jats:title>\n            <jats:p xml:lang=\"en\">We performed a retrospective analysis of prospectively collected data from patients with acute ischemic stroke treated with aspiration mechanical thrombectomy using the Tenzing 7 delivery catheter between January 2020 and July 2022 at 6 high volume stroke centers. Primary efficacy outcome was success in aspiration catheter delivery to the face of the thrombus, and primary safety end point was rate of procedural complication.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec xml:lang=\"en\">\n            <jats:title>Results<\/jats:title>\n            <jats:p xml:lang=\"en\">Of a total of 176 patients (mean age 70.1\u00b114.9 years, 56.3% female, 89.2% middle cerebral artery occlusions), first\u2010pass effect (modified Thrombolysis in Cerebral Infarction score\u22652B) was achieved in 90\/166 (54.2%) successfully revascularized patients. Tenzing 7 delivered the aspiration catheter of choice to the site of occlusion in 95.9% of cases; the clot was not crossed with Tenzing 7 in 69% of cases. Successful recanalization (modified Thrombolysis in Cerebral Infarction score\u22652B) was achieved in 94.9% of cases requiring a median of 1 pass (interquartile range 1\u20133). Nonflow limiting vessel dissection unrelated to Tenzing 7 occurred in 4 patients (2.3%), and intracranial vessel perforation unrelated to Tenzing 7 occurred in 4 cases (2.3%).<\/jats:p>\n          <\/jats:sec>\n          <jats:sec xml:lang=\"en\">\n            <jats:title>Conclusion<\/jats:title>\n            <jats:p xml:lang=\"en\">This multicenter clinical experience using Tenzing 7 in mechanical thrombectomy demonstrated high rates of technical success and a modest complication rate, similar to the published rates of technical success with other thrombectomy techniques.
