INFLATABLE MEDICAL DEVICES
Inflatable medical devices and methods for making and using the same are disclosed. The inflatable medical devices can be medical balloons. The balloons can be configured to have a through-lumen or no through-lumen and a wide variety of geometries. The device can have a high-strength, non-compliant, fiber-reinforced, multi-layered wall. The inflatable medical device can be used for angioplasty, kyphoplasty, percutaneous aortic valve replacement, or other procedures described herein.
1 . A method for using an inflatable device for use at a target site in a biological body comprising:
inserting a working channel through the biological body, wherein the working channel has an inner diameter less than about 5 mm, and wherein the working channel has a distal port, and wherein the distal port is positioned adjacent to, or at, the target site;
delivering a first balloon through the working channel and positioning the first balloon at the target site;
after the delivering of the first balloon, delivering a second balloon through the working channel and positioning the second balloon at the target site while the first balloon is at the target site; and
delivering an unsupported pressure in free air of greater than or equal to about 150 psi to the first balloon.
2 . The method of claim 1 , wherein the first balloon has a balloon wall and wherein the balloon wall has a balloon wall area, and wherein the working channel has a working channel area, and wherein the balloon wall area is greater than or equal to about 55% of the working channel area.
3 . The method of claim 1 , further comprising delivering an unsupported pressure of greater than 200 psi to the second balloon.
4 . The method of claim 1 , further comprising inflating the first balloon
5 . The method of claim 4 , further comprising inflating the second balloon while the first balloon is inflated.
6 . The method of claim 4 , further comprising inflating the second balloon concurrent with inflating the first balloon.
7 . The method of claim 1 , further comprising deflating the first balloon.
8 . The method of Claim I, further comprising removing the first balloon through the working channel.
9 . The method of claim 1 , wherein the first balloon is in fluid communication with a first fluid channel.
10 . The method of claim 9 , wherein the second balloon is in fluid communication with a second fluid channel.
11 . The method of claim 1 , wherein the target site is located in a bone.
12 . The method of Claim II, wherein the target site is located in a vertebra.
13 . The method of claim 1 , further comprising delivering MMA to the target site.
14 . A method for using an inflatable device for use at a target site in a biological body comprising:
inserting a working channel through the biological body, wherein the working channel has an inner diameter less than about 5 mm, and wherein the working channel has a distal port, and wherein the distal port is positioned adjacent to, or at, the target site;
delivering a first balloon through the working channel and positioning the first balloon at the target site; and
delivering a second balloon through the working channel and positioning the second balloon at the target site, and
wherein the first balloon is attached to a first deployment system and the second balloon is attached to a second deployment system, and wherein the position and orientation of the first deployment system is manipulatable separate from the position and orientation of the second deployment system; and
delivering an unsupported pressure of greater than about 150 psi to the first balloon.
15 . The method of claim 14 , wherein delivering the second balloon comprises delivering the second balloon while the first balloon is at the target site.
16 . The method of claim 14 , further comprising inflating the first balloon
17 . The method of claim 16 , further comprising inflating the second balloon while the first balloon is inflated.
18 . The method of claim 16 , further comprising inflating the second balloon concurrent with inflating the first balloon.
19 . The method of claim 14 , wherein the first balloon is in fluid communication with a first fluid channel.
20 . The method of claim 19 , wherein the second balloon is in fluid communication with a second fluid channel.
21 . The method of claim 14 , wherein the target site is located in a vertebra.
22 . The method of claim 14 , further comprising delivering MMA to the target site.
23 . A method for using an inflatable device for use at a target site in a biological body comprising:
inserting a working channel through the biological body, wherein the working channel has an inner diameter less than about 5 mm, and wherein the working channel has a distal port, and wherein the distal port is positioned adjacent to or at the target site;
delivering a first balloon through the working channel and positioning the first balloon at the target site;
delivering a second balloon through the working channel and positioning the second balloon at the target site concurrent with delivering a first balloon through the working channel; and
delivering an unsupported pressure of greater than about 150 psi to the first balloon.
24 . The method of claim 23 , further comprising delivering MMA to the target site.
25 . A method for using an inflatable device for use at a target site having a target site first segment and a target site second segment in a biological body comprising:
inserting a first working channel through the biological body, and wherein the first working channel has a first distal port, and wherein the first distal port is positioned adjacent to or at the target site first segment;
inserting a second working channel through the biological body, and wherein the second working channel has a second distal port, and wherein the second distal port is positioned adjacent to or at the target site second segment;
26 . The method of claim 25 , further comprising:
delivering a first balloon through the first working channel and positioning the first balloon at the target site first segment;
delivering a second balloon through the second working channel and positioning the second balloon at the target site second segment; and
delivering an unsupported pressure of greater than about 150 psi to the first balloon.
27 . The method of claim 25 , wherein the first working channel has an inner diameter less than about 5 mm.
28 . The method of claim 25 , wherein delivering the second balloon comprises delivering the second balloon concurrent with delivering a first balloon through the working channel.
