Vascular occlusion devices

A collection of occlusive vascular devices comprising

• a first occlusive device comprising
• a molded or extruded shape memory polymer material that is formed
• in a pre-deployed state as a monolithic, non-wound, elongate member configured for delivery via a catheter, wherein a fluid channel is formed along an entire length of the elongate member from a distal end to a proximal end to provide a continuous fluid channel through the elongate member;
• and
• in a deployed state as a coiled member, which coils from a form of the elongate member, wherein
• the fluid channel is defined by at least two continuous opposing side walls and a continuous base wall formed between the opposing side walls, each of the base wall and side walls extending entirely through the elongate member from the proximal end to the distal end;
• and
• at least a second occlusive device identical to the first occlusive device;
• wherein
• the collection includes at least both the first and second occlusive devices which, when connected end to end in series, provide a continuous fluid channel configured to transmit fluid through each elongate member from the proximal end of a most proximal of the first and second occlusive devices to the distal end of a most distal of the first and second occlusive devices.

An occlusive vascular device comprising

• a shape memory material that is formed
• in a pre-deployed state as a elongate member;
• in a deployed state as a spring-shaped coil configured to anchor against a vascular lumen;
• and
• a fabric attached to and extending along a length of the occlusive vascular device, wherein
• the fabric is collapsed about the elongate member in the pre-deployed state;
• and
• the fabric is unfurled to span across and extend interstitially between successive windings of the spring-shaped coil and occlude the vascular.
