Abstract
A tapered implantable device includes an ePTFE tubular member having a tapered length portion. The tapered length portion provides rapid recovery properties. The tapered length portion can feature a microstructure that includes a multiplicity of bent fibrils.
Claims14
An implantable article comprising:
- a polymeric tube comprising a first length portion having a first diameter and a second length portion having a second diameter, the first length portion having a first rapid recovery property defined by a difference between an extended length of the first length portion and a recovered length of the first length portion;
- and
- a tapered length portion extending between the first length portion and the second length portion, the tapered length portion having a tapered length portion rapid recovery property that is defined by a difference between an extended length of the tapered length portion and a recovered length of the tapered length portion, wherein the first rapid recovery property differs from the tapered length portion rapid recovery property at a compression ratio between 30% and 95%.
An implantable article comprising:
- a polymeric tube comprising a first portion having a first diameter and a second portion having a second diameter, the first diameter being less than the second diameter, and the first portion having a first rapid recovery property defined by a difference between an extended length of the first portion and a recovered length of the first portion;
- and
- a tapered portion extending between the first portion and the second portion, the tapered portion having a tapered portion rapid recovery property that is defined by a difference between an extended length of the tapered portion and a recovered length of the tapered portion, wherein the tapered portion rapid recovery property defines a compression ratio of between 30% and 95%.
