Abstract
The present invention provides a surgical device including an elongate body defining a fluid flow path therethrough. An expandable element may be coupled to the elongate body and placed in fluid communication with the fluid flow path. Moreover, the surgical device may include a first leak detection element at least partially surrounding a portion of the expandable element, and a second leak detection element may be provided in fluid communication with the fluid flow path. In addition, a console may be provided, where the console may be in communication with the first and second leak detection elements. Further, a supply of cryogenic fluid as well as a vacuum source may be provided in fluid communication with the fluid flow path.
Claims4
A method for leak detection in a medical device, comprising:
- circulating a fluid through a fluid flow path to an expandable element, the expandable element being substantially disposed within a mesh leak detection element;
- measuring an impedance between the mesh leak detection element and a second leak detection element in the fluid flow path;
- and
- discontinuing fluid flow in response to the impedance measurement.
A method for leak detection in a medical device, comprising:
- circulating a fluid through a fluid flow path to an expandable element, the expandable element being substantially disposed within a mesh leak detection element;
- detecting an electrical short between the mesh leak detection element and a second leak detection element in the fluid flow path;
- and
- discontinuing fluid flow in response to the detected electrical short.
