Best-in-Class Compression Resistance

Express™ SD Renal and Biliary Premounted Stent System Best-in-Class Compression Resistance
Express™ SD Renal and Biliary Premounted Stent System Compression Resistance bench test results
Compression Resistance defined as the force required to compress the fully expanded stent. Compression Resistance measured using the hoop force tester in 37° C air. Bench testing performed by Boston Scientific Corporation. Data on file. N=3. Express SD, RX Herculink Plus, Herculink Elite, PALMAZ Blue and Racer stents tested: 6 x 18 mm. Formula 418 RX tested: 6 x 20mm. Bench test results may not necessarily be indicative of clinical performance.
 

Minimal Foreshortening

Express™ SD Renal and Biliary Premounted Stent System Foreshortening bench test results
Foreshortening defined as the change in stent length from crimped conditions to nominally expanded condition in 37° C water, as measured by a magnified vision system. Bench testing performed by Boston Scientific Corporation. Data on file. N=3. Express SD, RX Herculink Plus, Herculink Elite, PALMAZ Blue and Racer stents tested: 6 x 18 mm. Formula 418 RX tested: 6 x 20mm. Bench test results may not necessarily be indicative of clinical performance.
 

Very Low Recoil

Express™ SD Renal and Biliary Premounted Stent System shows Very Low Recoil in Bench Tests
Stent Recoil defined as the change in stent diameter from nominally pressurized catheter to non-pressurized catheter condition in 37° C water, as measured by a magnified vision system. Bench testing performed by Boston Scientific Corporation. Data on file. N=3. Express SD, RX Herculink Plus, Herculink Elite, PALMAZ Blue and Racer stents tested: 6 x 18 mm. Formula 418 RX tested: 6 x 20mm. Bench test results may not necessarily be indicative of clinical performance.

Clinical Information

RENAISSANCE Clinical Trial

Overview The RENAISSANCE Trial was a prospective, multi-center, single arm study designed to evaluate the Express SD Renal Premounted Stent System in the treatment of atherosclerotic lesions in the aortorenal ostium.

The primary objective was to demonstrate superiority of the duplex triggered, angiographically-confirmed binary restenosis rate at 9-months over the 40% pre-specified Objective Performance Criterion (OPC) representative of PTRA. 

Trial Design The RENAISSANCE Trial enrolled 100 patients (117 lesions) with de novo or restenotic ostial atherosclerotic lesions ≤15mm long in vessels between 4.0 and 7.0mm diameter with diameter stenosis ≥70%. 

Outcomes Primary Endpoint: 21.3% binary in-stent restenosis rate at 9-months, defined as the proportion of target lesions with ≥50% diameter stenosis based on angiographic core lab assessment.
