Latest Patents

Farrissey's latest patents include the Expandable Introducer Sheath and the Transseptal Crossing Needle Device. The Expandable Introducer Sheath is designed for use in interventional procedures, allowing for insertion into a treatment vessel in a first unexpanded configuration. This sheath can expand in diameter during the insertion of a device through its main lumen and can then re-collapse to its unexpanded diameter. The design features an inner heat-set folded layer and an outer elastomeric layer, which provides a barrier to minimize the risk of vessel trauma during the unfolding process.

The Transseptal Crossing Needle Device is another innovative creation by Farrissey. This device facilitates the insertion of an outer sheath through a septum. It includes an inner dilator sheath that receives a needle with a curved end portion. The needle's design, featuring an angled transverse end surface, is intended to reduce or eliminate skiving of material from the inner walls of the sheath, enhancing the safety and effectiveness of the procedure.
