IN-VITRO DEVICE MONITORING DURING MINIMALLY INVASIVE ABLATION THERAPY
First Claim
1. A method of monitoring or controlling an interventional procedure, comprising the acts of:
- establishing a procedure-specific analyte and a set-point value thereof;
obtaining a sample of a bodily fluid;
performing the interventional proceduredetermining a value of the analyte in the bodily fluid; and
comparing the analyte value with the set-point value.

Abstract
A method and apparatus for monitoring and controlling interventional therapy is described, where the interventional therapy results in the destruction of tissue and the release of chemical markers. When interventional therapy results in destruction of a patient tissue, such as cancerous tissue, a variety of chemical markers may be released into the bloodstream. An in-vitro diagnostic (IVD) device may be used to measure the concentration of an analyte representing a marker and compare the measured concentration with a predetermined set point so as to monitor or control the procedure. The blood for the analysis may be obtained either inter-procedurally or intra-procedurally depending on the promptness of the effect being measured and the speed of measurement.

20. A system for interventional treatment comprising:
-
an interventional apparatus capable of delivering or removing localized energy to a location in a patient body; an in-vitro diagnostic (IVD) device; wherein a bodily fluid is analyzed by the IVD device to determine a value of an analyte, and the value of the analyte is compared with a pre-determined value to control a value of the localized energy. - View Dependent Claims (21, 22, 23, 24)

25. A computer program product, stored on a machine readable medium, comprising:
instructions for configuring a computer to; accept a measured value of an analyte from an in-vitro diagnostic (IVD) device; compare the measured value of the analyte with a stored value and control the energy delivered or removed from a patient by an interventional device based on a relation between the measured value and the stored value. - View Dependent Claims (26, 27)
