【発明の名称】灌流遮断カテーテル装置及び方法
Document Type and Number:
Japanese Patent JP2002523192
Kind Code:
A
Abstract:
A catheter (10) includes an introducer and a flow isolator adapted for disposition in a primary conduit (200) to facilitate flow in the primary conduit while inhibiting flow and intersecting secondary conduits (240,250,260,270). The flow isolator may include a tubular mesh and surrounding balloon structure (16). Alternatively, a sleeve can be provided with a primary opening and a secondary opening which are sized to inflate the sleeve with the body fluid. Structures for deploying the sleeve between a low-profile state and high-profile state may include expandable fingers, or pneumatic chambers inflatable from an external source. In operation the sleeve can be forced by the body fluid against the intersection with the secondary conduits to achieve isolation. Alternatively, the pneumatic chambers can be inflated to form seals with the primary conduit. A blood filter or snare is contemplated to filter any blood clots which may develop around the flow isolator.
