Abstract

A medical device made of a hybrid polymeric structure includes a tubular body including a first layer and a second layer. The first layer includes a fibrous matrix comprising a plurality of randomly oriented nanofibers made at least in part of a first polymeric material and pores formed between at least a portion of the nanofibers. The second layer is made at least in part of a second polymeric material. At least a portion of the second layer is disposed about and between the plurality of nanofibers such that at least a portion of the second polymeric material is embedded into at least a portion of the pores of the fibrous matrix.
