Latest Patents
One of Sew-Wah Tay's latest inventions is the expandable introducer sheath. This invention comprises a method and device designed to provide an expandable introducer sheath. The method involves inserting an elongate flexible tubular sheath into a vessel, with a proximal end extending outward through the skin, allowing for the slidable reception of intravascular devices. When a larger size introducer sheath is required, the sheath can be manipulated while still in the vessel to expand its inner diameter. In one embodiment, the sheath is constructed from a shape-memory polymer, which is manipulated by inserting a heated mandrel within the sheath to facilitate expansion. This innovative design ensures that the sheath retains its expanded inner diameter. Alternatively, the sheath can be formed from a telescoping multi-tubular arrangement of progressively larger tubes. The insertion of this inventive sheath into the skin necessitates only a single small puncture, which can be expanded as needed while the sheath remains in place.
