Echogenic occlusive balloon and delivery system

摘要

A vessel occlusion apparatus includes an elongate shaft having a fluid delivery lumen; and an expandable member carried on a distal an end portion of the shaft, the expandable member comprising a body defining an interior region, the interior region communication with the fluid delivery lumen, the body comprising a wall having one or more embedded fluid pockets therein, each of the one or more pockets containing a fluid capable of being imaged, e.g., having echogenic qualities for detection using ultrasound imaging.

主权项

1. A system, comprising:
in combination, an echogenic balloon apparatus and an echogenic delivery apparatus, wherein the balloon apparatus comprises an elongate shaft having a fluid delivery lumen, and an expandable balloon carried on a distal end portion of the elongate shaft, the balloon comprising a balloon body defining an interior region in communication with the fluid delivery lumen of the elongate shaft, the balloon body comprising a wall having one or more embedded fluid pockets therein; and the delivery apparatus comprises an elongate tubular delivery member having a proximal portion, a distal portion, a lumen extending between the proximal and distal portions and sized to accommodate insertion of the balloon apparatus therethrough, and a wall defining at least a portion of the distal portion of the tubular delivery member, the tubular delivery member wall having one or more embedded fluid pockets; each of the respective fluid pockets in the balloon body wall and tubular delivery member wall containing an echogenic fluid such that a substantial cross section of the balloon body wall can be imaged using an ultrasound imaging device when the balloon is in an expanded or deflated configuration.
