Abstract

Claims (27)

1. A delivery member for delivering an implantable medical device to a target location of a body vessel, the delivery member comprising:

a proximal hypotube;

a flexible coil extending from a distal end of the proximal hypotube;

a compressible distal hypotube extending from a distal end of the flexible coil;

a lumen extending from a proximal end of the proximal hypotube, through the proximal hypotube, through the flexible coil, through the compressible distal hypotube, and to a distal end of the compressible distal hypotube;

a sleeve extending along a majority of the flexible coil, wherein the sleeve is effective to inhibit radial expansion of the flexible coil;

a stretch-resistant loop wire comprising a first end and a second end, each affixed to the proximal hypotube, the stretch-resistant loop wire further comprising a loop opening positioned approximate a distal end of the compressible distal hypotube,

wherein the stretch-resistant loop wire is effective to inhibit longitudinal elongation of the flexible coil; and

a pull wire extending through the lumen,

wherein the stretch-resistant loop wire and the pull wire are positioned to secure the implantable medical device to the delivery member,

wherein the stretch-resistant loop wire and the pull wire are movable to release the implantable medical device from the delivery member,

wherein the stretch-resistant loop wire is under tension when the implantable medical device is secured to the delivery member,

wherein the compressible distal hypotube is compressed due to tension in the stretch-resistant loop wire when the implantable medical device is secured to the compressible distal hypotube, and

wherein the compressible distal hypotube is movable to decompress upon movement of the stretch-resistant loop wire and pull wire to release the implantable medical device.

2. The delivery member of claim 1 ,

wherein the flexible coil is more flexible than one or both of the proximal hypotube and the compressible distal hypotube.

3. The delivery member of claim 1 , wherein the flexible coil comprises:

a non-radiopaque proximal coil extending from a proximal end of the flexible coil;

a non-radiopaque distal coil extending from the distal end of the flexible coil; and

a radiopaque central coil extending between the non-radiopaque proximal coil and the non-radiopaque distal coil.

4. The delivery member of claim 1 , where in the flexible coil comprises:

a wire wound to form the flexible coil and defining a portion of the lumen, the wire comprising a diameter measuring from about 0.0008 inch to about 0.005 inch.

5. The delivery member of claim 4 , wherein the wire comprises a substantially circular cross section.

6. The delivery member of claim 1 , further comprising:

a distal portion length measurable from the distal end of the compressible distal hypotube to a proximal end of the flexible coil,

wherein the distal portion length measures about 40 cm.

7. The delivery member of claim 1 , wherein the compressible distal hypotube comprises a spiral cut.
