Abstract
A vascular implant configured for occluding a vasculature of a patient having a biocompatible polymeric structure formed of a plurality of filaments spaced to maintain surface porosity and an inner radiopaque coil positioned within the longitudinally extending opening of the polymeric structure and attached to the polymeric structure. The polymeric structure and radiopaque coil are attached forming a joint at the distal end.
Claims20
A vascular implant configured for occluding a vasculature of a patient, the vascular implant comprising:
- a biocompatible polymeric structure formed of a plurality of filaments and having a proximal end and a distal end, the filaments spaced to maintain surface porosity, the polymeric structure forming a tubular body having a first longitudinally extending opening;
- and
- a radiopaque coil having a proximal end and a distal end, the radiopaque coil positioned within the longitudinally extending opening of the polymeric structure, wherein the polymeric structure and radiopaque coil are attached forming a joint at the distal end of the radiopaque coil along a length extending for at least 0.002 inches and not exceeding a length of about 0.050 inches, the polymeric structure covering the distal end of the radiopaque coil.

A vascular implant configured for occluding a vasculature of a patient, the vascular implant comprising:
- a biocompatible polymeric structure formed of a plurality of filaments and having a proximal end and a distal end, the filaments spaced to maintain surface porosity, the polymeric structure forming a tubular body having a first longitudinally extending opening;
- and
- an inner element composed of a radiopaque coil having a proximal end and a distal end, the radiopaque coil positioned within the longitudinally extending opening of the polymeric structure, wherein the polymeric structure and radiopaque coil are attached to form a joint at the distal end of the radiopaque coil along a length wherein the joint covers at least two distalmost coil windings of the radiopaque coil.

A vascular implant configured for occluding a vasculature of a patient, the vascular implant comprising:
- a biocompatible polymeric structure formed of a plurality of filaments and having a proximal end and a distal end, the filaments spaced to maintain surface porosity, the polymeric structure forming a tubular body having a first longitudinally extending opening;
- and an inner element composed of a radiopaque coil having a proximal end and a distal end, the radiopaque coil positioned within the longitudinally extending opening of the polymeric structure, wherein the polymeric structure and radiopaque coil are attached at a plurality of discrete spaced apart non-continuous regions at a distal portion of the radiopaque coil, wherein a distance from a proximalmost discrete region to a distalmost discrete region is between about 0.002 inches and about 0.050 inches.
