Detachable steel spring coils for vessel occlusion.

摘要
Spring coils for vessel occlusion were modified to include a screw-on attachment for delivery wire, which permitted safe and accurate placement of the coils. We successfully implanted coils in a dog and a lamb. They were easily retrieved from within the delivery catheters and the vessels, which is not possible with conventional coils. Coil design is described.
