Stent delivery device with embolic protection
First Claim
1. A device configured to deliver a stent within a body lumen and provide embolic protection, the delivery device comprising:
- a filter device adapted to provide embolic protection during a procedure, said filter device comprising;
a guidewire, a filter assembly mounted to said guidewire, and a restraining member adapted to apply a restraining force upon at least a portion of said filter assembly to prevent deployment of a filter;
a stent delivery device cooperating with said filter device, said stent delivery device comprising;
a stent adapted to be placed within the body lumen; and
a dilation assembly configured to support said stent and assist with placing said stent within the body lumen, said dilation assembly cooperating with said restraining member;
wherein said filter device, said dilation assembly, and said stent are substantially simultaneously disposed within the body lumen to deliver said stent to the body lumen.

Abstract
A delivery device adapted to insert and deploy a stent within a body lumen. The delivery device includes a guide member adapted to retain a dilation assembly and a stent within a lumen thereof until the stent is to be deployed into the body lumen. The delivery device is configured to enable simultaneous insertion of the guide member, dilation assembly, stent, and optional guidewire within a body lumen. Following deploying the stent, the delivery device can be removed, while providing the capability of optionally maintaining the guide member or the guidewire to function or act as an exchange wire for additional surgical devices.
