Abstract
An embolic protection device has a support frame incorporating tethering features for connecting the support frame distally and/or proximally and/or intermediately to a carrier. Tethers may also be used additionally or alternatively for connecting various elements of a support frame. The tethers may be used to connect a support hoop 503 to a tubular member 504. The tethers provide added safety and stability to the frame without any increase in the length of the device when wrapped down for delivery.
