METHOD AND SYSTEM FOR DELIVERING AN IMPLANT UTILIZING A LUMEN REDUCING MEMBER
First Claim
1. A method of delivering an implant through a vascular space to a vascular site in a body, the method comprising:
- providing a guide, a displacement member, a first catheter having a body, a distal end and a proximal end and defining a first cavity, and a second catheter having a body, a distal end and a proximal end and defining a second cavity, the second catheter being insertable within the first cavity;
advancing the distal ends of the first and second catheters together along the guide and through the vascular space to the vascular site;
removing the second catheter and the guide from the first cavity;
inserting the implant into the first cavity of the first catheter; and
advancing the implant through the first cavity to the vascular site using the displacement member.

Abstract
Method and system for inserting an implant, such as vaso-occlusive device, an embolic containment device, or a stent into a vascular space to a vascular site in a body utilizing a lumen-reducing catheter. The method and system can be used to treat aneurysm, tumors and other vascular malformations. A guide is inserted into the vascular space. First and second catheters are inserted into the vascular space along the guide. The first or delivery catheter defines a first cavity, and the second or lumen-reducing catheter defines a second, smaller cavity. The second catheter is inserted within the first catheter. In one embodiment, an implant is advanced together with the first and second catheters to a vascular site. In an alternative embodiment, after the first and second catheters are positioned, the guide and the second catheter are removed from the first cavity, and an implant is inserted through the first cavity. With these configurations, radial movement of the guide is restricted to the smaller, second cavity rather than the larger, first cavity.
