Abstract
An embolic coil delivery system includes a catheter and an embolic coil disposed within the catheter, the embolic coil including a coil wire and a fiber bundle. A method of producing an embolic coil delivery system includes: advancing a delivery sheath over a distal end of an embolic coil while applying tension to the embolic coil via a retaining device that is attached to the distal end of the embolic coil.
Claims20
A system comprising:
- a catheter having a delivery end;
- and an embolic coil at least partially disposed within the catheter, the embolic coil including a coil wire having an end fitting configured to releasably couple to an end fitting of a
- delivery wire, and multiple fiber bundles contacting the catheter, each fiber bundle having a first bundle end attached to the coil wire and a second bundle end opposite the first bundle end;
- wherein more fiber bundles are attached to a first half of the coil adjacent the end fitting than are attached to a second half of the coil.

A system comprising:
- a delivery wire with an end fitting;
- a coil wire having a first end, an opposite second end, and a midpoint located halfway between the first end and the second end;
- an end fitting at the first end of the coil wire, the end fitting configured to releasably couple the embolic coil to the end fitting of the delivery wire;
- and multiple fiber bundles attached to the coil wire;
- wherein more fiber bundles are attached to the coil wire between the first end and the midpoint than are attached to the coil wire between the second end and the midpoint, and wherein the coil is an embolic coil.

A system comprising:
- a catheter having a delivery end;
- a delivery wire with an end fitting;
- and an embolic coil disposed within the catheter, the embolic coil having a first half and a second half, the second half disposed between the first half and the delivery end of the catheter, the embolic coil including a coil wire and multiple fiber bundles contacting the catheter, the coil wire having an end fitting configured to releasably couple to the end fitting of the delivery wire and each fiber bundle extending from a first bundle end attached to the coil wire to a second bundle end opposite the first bundle end;
- and wherein more fiber bundles are attached to the first half of the embolic coil than are attached to a second half of the coil.
