Inflatable medical devices
Inflatable medical devices and methods for making and using the same are disclosed. The devices can be medical invasive balloons, such as those used for transcutaneous heart valve implantation, such as balloons used for transcatheter aortic-valve implantation. The balloons can have high strength, fiber-reinforced walls.
1 . A lamination apparatus, comprising:
a medical balloon comprising a plurality of layers in need of lamination; and
a vacuum bag in which the medical balloon is positioned;
wherein the vacuum bag is configured to be evacuated to laminate the medical balloon.
2 . The lamination apparatus of claim 1 , wherein the vacuum bag comprises opposed sheets of material between which the medical balloon is located.
3 . The lamination apparatus of claim 1 , further including a heater for heating the medical balloon.
4 . The lamination apparatus of claim 1 , further including a suction tube for evacuating the vacuum bag.
5 . The lamination apparatus of claim 1 , wherein at least one layer of the plurality of layers comprises one or more fibers.
6 . The lamination apparatus of claim 1 , wherein at least one layer of the plurality of layers comprises an adhesive.
7 . The lamination apparatus of claim 1 , wherein at least one layer of the plurality of layers comprises a seam.
8 . The lamination apparatus of claim 1 , wherein the medical balloon comprises a mandrel.
9 . The lamination apparatus of claim 8 , wherein the mandrel comprises a water-soluble mandrel.
10 . A lamination apparatus, comprising:
a medical balloon comprising a plurality of layers in need of lamination; and
an evacuated receiver comprising a vacuum bag in which the medical balloon is positioned;
wherein the receiver is configured to be evacuated to laminate the medical balloon.
11 . The lamination apparatus of claim 10 , wherein the evacuated receiver comprises opposed sheets of flexible material between which the medical balloon is located.
12 . The lamination apparatus of claim 10 , wherein at least one layer of the plurality of layers comprises: (i) one or more fibers; (ii) an adhesive; or (iii) a seam.
13 . The lamination apparatus of claim 10 , wherein the medical balloon comprises a mandrel.
14 . The lamination apparatus of claim 13 , wherein the mandrel comprises a water-soluble mandrel.
15 . A method of laminating a medical balloon having a plurality of layers in need of lamination, comprising:
placing the medical balloon into a vacuum bag; and
evacuating the vacuum bag to laminate the medical balloon.
16 . The method of claim 15 , further including the step of heating the medical balloon in the vacuum bag.
17 . The method of claim 15 , further including the step of providing the medical balloon over a mandrel.
18 . The method of claim 17 , further including the step of dissolving the mandrel.
