Abstract
An occlusion device for placement within a body vessel may include a wire constructed support structure having a covering applied thereto. The covering includes a mixture of PET and ultra-high molecular weight polyethylene (UHMWPE). The covering is applied to the support structure via an electrospinning process to produce a non-woven fiber covering having increase strain capabilities relative to an electrospun PET covering without UHMWPE. The device has a nominal state that is radially expanded and a delivery state that is radially compressed and longitudinally extended for disposal within a low-profile delivery sheath. The covering increased strain capability allows for the device to have relative large diameter in the nominal state while still being capable of low-profile delivery. This occlusion device can provide faster occlusive capability when deployed and does not rely on delayed embolization. The covering extends across the vessel upon deployment to provide instant occlusion.
