Abstract
A parent artery occlusion (PAO) device which provides for immediate occlusion of a cerebral artery to isolate a defect. The PAO device includes a self-expanding wire-frame prolate structure which is partially covered with an ePTFE membrane.
Claims21
A system comprising:
- a delivery member;
- and
- an embolic implant comprising:
- a wire frame structure comprising:
- a pair of opposing zigzag segments including a plurality of elements, each element of the plurality of elements defining an open end and a closed end opposite the open end, and each element of the plurality of elements being joined at the respective open end to another element via struts to form a central portion of the wire frame structure, the closed ends of the elements pointing proximally or distally away from a longitudinal center of the wire frame structure;
- a first plurality of longitudinally oriented struts extending from proximally pointing closed ends of the elements, the first plurality of longitudinally oriented struts being joined together at a proximal end of the wire frame structure;
- and
- a second plurality of longitudinally oriented struts extending from distally pointing closed ends of the elements, the second plurality of longitudinally oriented struts being joined together at a distal end of the embolic implant;
- a blood impermeable membrane covering at least a part of the wire frame structure and extending from the proximal end of the wire frame structure to at least distal to the longitudinal center of the wire frame structure;
- and
- a detachment joint configured to releasably join a proximal end of the wire frame structure to the delivery member.

An embolic implant comprising:
- a wire frame structure comprising:
- a pair of opposing zigzag segments including a plurality of elements, each element of the plurality of elements defining an open end and being joined at the respective open end to another element via struts to form a central portion of the wire frame structure, the elements defining proximal or distal vertices pointing proximally or distally away from a longitudinal center of the wire frame structure;
- a first plurality of longitudinally oriented struts extending from the proximally pointing vertices of the elements, the first plurality of longitudinally oriented struts being joined together at a proximal end of the wire frame structure;
- and
- a second plurality of longitudinally oriented struts extending from the distally pointing vertices of the elements, the second plurality of longitudinally oriented struts being joined together at a distal end of the embolic implant;
- and
- a blood impermeable membrane covering at least a part of the wire frame structure extending from the proximal end of the wire frame structure to at least distal to the longitudinal center of the wire frame structure;
- and
- a detachment joint configured to releasably join a proximal end of the wire frame structure to a delivery member.
