Abstract

The present disclosure describes implantable medical devices comprising covers, such as a balloon cover. Such devices can comprise a first layer of a porous polymeric material, such as ePTFE, surrounded by layers of a porous polymeric material having an imbibed elastomer, such as polyurethane. The cover can be used to assist in deployment of an expandable implant, such as a stent-graft, within the body of the patient.

First claim

1 - 7 . (canceled)

8 . An outer cover for a medical balloon comprising at least one pleat aligned along at least a portion of a longitudinal axis.

9 . The outer cover for a medical balloon of claim 8 , further comprising a medical balloon having the same number of pleats as the outer cover, wherein the outer cover coaxially surrounds the medical balloon, and wherein an inner surface of the outer cover substantially conforms to an outer surface of the medical balloon.

10 . The outer cover for a medical balloon of claim 8 , wherein the outer cover comprises ePTFE.

11 . The outer cover for a medical balloon of claim 9 , wherein the medical balloon comprises a non-compliant material.

12 . A catheter assembly comprising:
a catheter tube; a balloon coupled to the catheter tube and comprising at least one pleat when in a collapsed configuration; and an outer cover coaxially surrounding the balloon comprising at least one pleat, wherein an inner surface of the outer cover substantially conforms to an outer surface of the balloon.

13 . The catheter assembly of claim 12 , wherein the outer cover an innermost porous polymer layer and at least one comprising a porous polymer imbibed with an elastomeric component.

14 . The catheter assembly of claim 12 , wherein the balloon comprises a non-compliant material.

15 . The catheter assembly of claim 12 , further comprising an expandable implant.

16 . The catheter assembly of claim 15 , wherein the expandable implant comprises a stent member.

17 . The catheter assembly of claim 16 , wherein the stent member comprises a malleable metal.

18 . The catheter assembly of claim 16 , wherein the stent member comprises at least one ring.

19 . The catheter assembly of claim 15 , wherein the expandable implant comprises at least one biocompatible polymeric graft member.
