Patent ID: 8734379

Claim:
A medical shunt system, comprising: a tubular sheath designed for partial insertion into a fetal bladder, the sheath including a lumen; and a flexible implantable device for insertion into the sheath, the implantable device comprising: a flexible anchor comprising a proximal disk-shaped member, a distal disk-shaped member parallel to the proximal member, a trunk connecting the proximal and distal members, and a passage that extends through the trunk; an elongate flexible catheter extending through the trunk, the catheter defining a plurality of proximal ports, a plurality of distal ports, a longitudinal axis, and a catheter lumen providing fluid communication between the proximal ports and the distal ports, a proximal portion and a distal portion of the catheter each having a curved pig-tail shape when not under force from another member; a rigid guidewire for insertion into the catheter lumen and for maintaining the catheter in an elongate disposition when located within the lumen of the sheath; a rigid and elongate delivery member releasably fixed to the anchor, wherein the delivery member is designed to both push and pull the implantable device through the lumen of the sheath, and wherein the delivery member is designed to be released from the anchor after placement of the implantable device; and wherein the implantable device is designed to be compressed into the lumen of the sheath so as to be deployed into a fetal bladder.
