Embolic protection device having inflatable frame
First Claim
1. An embolic protection device for capturing emboli during treatment of a stenotic lesion in a body vessel, the device comprising:
- an inflatable frame having a deployed state and an undeployed state, the inflatable frame including a proximal portion extending to a distal portion, the proximal portion defining a proximal opening in fluid communication with the distal portion for supplying fluid thereto, the distal portion having a predetermined shape and extending freely independent of any support member to a closed distal end when the inflatable frame is in the deployed state, the closed distal end being a free end independent of any support member connected thereto; and
a filter attached to the inflatable frame for capturing emboli, the filter having a lip attached to the inflatable frame, a body extending distally from the lip, and a closed tail;
wherein the distal portion of the inflatable frame extends toward the closed tail of the filter to the closed distal end.

Abstract
An embolic protection device for capturing emboli during treatment of a stenotic lesion in a body vessel is provided. The device includes an inflatable frame having a deployed state and an undeployed state and a filter attached to the inflatable frame for capturing emboli. The inflatable frame includes a distal portion having a predetermined shape and extending freely to a closed distal end when the inflatable frame is in the deployed state. The filter includes a lip attached to the inflatable frame to define an open end of the filter when the inflatable frame is in the deployed state, a body extending from the lip and disposed about the inflatable frame, and a closed tail configured to capture the emboli during treatment of the stenotic lesion.

8. An embolic protection assembly for capturing emboli during treatment of a stenotic lesion in a body vessel, the assembly comprising:
-
a balloon catheter having a tubular body portion and an expandable balloon fluidly connected to the tubular body; and an embolic protection device at least partially coaxially disposed within the balloon catheter during treatment of the stenotic lesion in the body vessel, the embolic protection device comprising; an inflatable frame having a deployed state and an undeployed state, including a proximal portion extending to a distal portion, the proximal portion defining a proximal opening in fluid communication with the distal portion for supplying fluid thereto, the distal portion having a predetermined shape and extending freely independent of any support member to a closed distal end when the inflatable frame is in the deployed state, the closed distal end being a free end independent of any support member connected thereto; and a filter including a lip attached to the inflatable frame to define an open end of the filter when the inflatable frame is in the deployed state, a body extending from the lip and disposed about the inflatable frame, and a closed tail configured to capture the emboli during treatment of the stenotic lesion; wherein the distal portion of the inflatable frame extends toward the closed tail of the filter to the closed distal end. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15, 16)
