Here's what makes peripheral testing unique. Your femoral stent gets compressed with every step the patient takes. Your carotid system must navigate tortuous anatomy without releasing embolic particles that cause strokes. We help you prove your device survives the extreme mechanical forces peripheral territories demand.
Peripheral devices face forces coronary devices never see. Your femoral stent endures compression, flexion, and torsion with every step. Carotid devices must cover plaque without releasing embolic particles. AAA grafts need seal zones that prevent leaks while accommodating tortuous vessels. Drug-eluting devices require sustained activity over long lesions. Each territory has distinct challenges.
We test mechanical performance through compression, flexion, and torsion protocols. These replicate what happens during normal walking. Our vascular labs have anatomically accurate models. Carotid bifurcations. Aortic aneurysms. Lower extremity vessels with realistic calcification and tortuosity. High-resolution imaging tracks device expansion, apposition, and seal quality.
Your carotid stent compresses atherosclerotic plaque against vessel walls. We evaluate neointimal hyperplasia over struts, measuring tissue growth that could cause restenosis. Our pathologists examine endothelialization completeness and inflammation severity using standardized grading. This demonstrates your stent maintains vessel patency without triggering excessive tissue reactions that could reblock the artery or destabilize plaque that increases stroke risk.
Your stent graft contacts aortic and iliac tissue at seal zones where hooks or barbs may penetrate vessel walls. We evaluate tissue response at attachment sites, measuring inflammation, vessel wall integrity, and healing patterns. We also assess graft material biocompatibility and whether tissue grows into graft interstices appropriately. Our pathologists score these responses using ISO 7198 protocols for vascular grafts. This demonstrates your device achieves stable fixation without excessive vessel injury and shows that graft healing prevents endoleaks while maintaining structural integrity.
Your IVC filter struts penetrate or contact the caval wall chronically. We evaluate tissue response at strut-wall interfaces, measuring inflammation, vessel wall integrity, and tissue encapsulation that affects retrievability. Our pathologists assess endothelial healing over struts and fibrotic tissue formation using ISO 10993 protocols for chronic vascular implants. This demonstrates your filter achieves stable fixation without causing excessive vessel wall injury or tissue ingrowth that prevents retrieval in temporary designs.
Your embolic protection device contacts blood briefly during procedures. We evaluate blood contacting material biocompatibility, measuring platelet changes and potential for thrombosis on filter surfaces. Our testing follows ISO 10993 hemocompatibility protocols for short-term blood contact. This demonstrates your filter captures emboli safely without causing blood reactions that could create new complications during protected interventions.
Your drug-coated stent must prevent neointimal tissue from reblocking vessels. We evaluate neointimal hyperplasia, the excessive smooth muscle cell growth that causes restenosis at multiple timepoints. Our pathologists measure neointimal thickness, assess inflammation severity, and verify complete endothelial coverage over struts using standardized grading. We also evaluate polymer biocompatibility and drug effects on healing. This demonstrates your drug dosing prevents reblockage without delaying endothelialization that protects against late thrombosis.
Your drug-coated balloon must prevent peripheral vessel reblockage without leaving a permanent implant behind. We evaluate neointimal thickness in treated segments, measuring how much scar tissue develops after drug treatment. Our pathologists assess inflammation patterns, endothelial healing quality, and media layer integrity using standardized histological grading. This demonstrates your drug concentration prevents excessive smooth muscle proliferation without causing chronic vessel inflammation or delayed healing that increases late restenosis risk.
Let's talk about your device. Carotid. AAA. Femoropopliteal. What territory. What biomechanical stresses it faces. We'll design a validation strategy that demonstrates durability under the forces your device will actually encounter.
