iScience Interventional introduces micro-aspiration retinal cannula
iScience Interventional launched the iMARC Micro-Aspiration Retinal Cannula at the joint meeting of the American Academy of Ophthalmology and Pan-American Association of Ophthalmology.
The micron-scale retinal aspirator is designed to deliver self-sealing retinotomies. Its coaxial design facilitates controlled, efficient, precise fluid aspiration, according to materials provided by the company.
The iMARC's 25-gauge main shaft is 30 mm long and is designed to produce an annular vacuum to control retinal tissue. The 125-µm inner polyimide microneedle penetrates the retina to aspirate subretinal fluid, according to the brochure.
A side arm offers access to the annular space for fluid infusion and vacuum control. The main Luer connector can be attached to a vitrectomy, syringe or other vacuum source.
Additional features include a flow path engineered for maximum flow rate, a proprietary design for preventing excessive ingress of retinal tissue and a beveled tip that penetrates retinal tissue more easily, according to the brochure.
