Abstract
Devices and methods for accessing and treating bodily vessels and cavities are disclosed. The devices can have everting balloon catheters that can deliver heating or cooling to biological vessels.
Claims16
A thermal treatment system comprising:
- a radially outer catheter;
- a radially inner catheter slidably translatable inside the outer catheter;
- an everting balloon attached at a first end to the outer catheter and at a second end to the inner catheter;
- a thermometer attached to and/or embedded in the everting balloon;
- a heater;
- a first fluid media heated above 55° C., wherein the first fluid media is exposed to the heater and inside of the everting balloon;
- and
- a pump in fluid communication with the heater and configured to pressurize the first fluid media.
5 more elements
A method for thermal treatment of biological tissue comprising:
- positioning a device in a target site, wherein the device comprises an outer catheter, an inner catheter slidably translatable inside of the outer catheter, and an everting balloon, wherein a first end of the everting balloon is attached to the outer catheter, and wherein a second end of the everting balloon is attached to the inner catheter;
- delivering a media under pressure to the everting balloon;
- everting the everting balloon at the target site;
- heating the media to or above 55° C. with a heater, wherein the media is exposed to the heater and inside of the everting balloon;
- and
- bending the heater, wherein bending the heater comprises compressing the heater.
3 more elements
A thermal treatment system comprising:
- a radially outer catheter;
- a radially inner catheter slidably translatable inside the outer catheter;
- an everting balloon attached at a first end to the outer catheter and at a second end to the inner catheter, wherein a length of the everting balloon is more thermally insulated than the remainder of the everting balloon;
- a heater;
- a first fluid media heated above 55° C., wherein the first fluid media is exposed to the heater and inside of the everting balloon;
- and
- a pump in fluid communication with the heater and configured to pressurize the first fluid media.
