Abstract
An intravascular heat transfer device is provided with a mixing-inducing surface formed by an easily manufacturable process. The device can have a plurality of elongated, articulated segments, each having a mixing-inducing exterior surface. A flexible joint connects adjacent elongated, articulated segments. The device may be conveniently formed, e.g., by vapor deposition or molding, and further lacks undercuts so that the same may be conveniently removed from, e.g., a two-part mold.
Claims17
A heat transfer device for intravascular temperature control of a patient, comprising:
- a flexible layer of a material, the flexible layer having a feature to produce mixing in fluid flowing adjacent said layer, the flexible layer and feature shaped and configured such that the flexible layer may be removed from a multi-part mold in the absence of an undercut,
- wherein the heat transfer device includes heat transfer segments separated by articulating joints.
A method for performing a medical procedure while managing and controlling the temperature of the patient, comprising:
- intravascularly inserting a catheter having a heat transfer element into a patient to be treated, the heat transfer element being formed of a flexible layer of a material, the flexible layer having a feature to produce mixing in fluid flowing adjacent said layer, the flexible layer and feature shaped and configured such that the flexible layer may be removed from a multi-part mold in the absence of an undercut;
- and
- cooling or heating the heat transfer element to control the patient's temperature.
