The present invention provides a vascular catheter apparatus for temperature measurement of vascular tissue, comprising a flexible body (14, 15, 18), at least two thermal sensors (10) mounted on resiliently biased projections (11) depended from the body; and a carrier (13) for transmitting temperature data at the vascular wall from the sensors (10) to a remote device. A computer program associated with the vascular catheter apparatus is provided for manipulating image data and temperature data to generate an output in which the temperature data is mapped onto a corresponding position on an image where that temperature data was detected to provide an integrated graphical image output. The temperature data is thermography data that represents surface temperature at a vascular wall, and the image data is representative of the vascular wall morphology.
A vascular catheter apparatus for temperature measurement of vascular tissue, comprising a flexible body, at least two thermal sensors mounted on resiliently biased projections depended from the body, and a carrier for transmitting temperature data at the vascular wall from the sensors to a remote device.
An apparatus according to any preceding claim, wherein the sensor is a thermistor.
An apparatus according to any preceding claim, additionally comprising a remote device adapted to acquire substantially continuous temperature measurements by continuous sampling of data from said apparatus.
An apparatus according to any preceding claim, wherein the projections comprise a superelastic material.
An apparatus according to any preceding claim, wherein the apparatus comprises a distal end, comprising the sensors and projections, and a proximal end comprising connection means adapted to enable electric and/or mechanical contact between the remote device and the sensors.
An apparatus for manipulating a multiple lumen catheter, comprising a first lumen mount for holding a first lumen of the catheter, and a second lumen mount for holding a second lumen of the catheter, and a drive mechanism, wherein each of the first and second lumen mounts is selectively connectable to the drive mechanism for both independent and relative movement with respect to the other lumen mount to control the configuration of the catheter.
A computer program product comprising computer executable instructions for manipulating image data and temperature data to generate an output in which the temperature data is mapped onto a corresponding position on an image where that temperature data was detected to provide an integrated graphical image output, wherein the temperature data is thermography data that represents surface temperature at a vascular wall, and the image data is representative of the vascular wall morphology.
A method of obtaining temperature data at a vascular wall comprising the steps of withdrawing a thermography catheter that senses vascular wall temperature over a predetermined length of the vascular tissue and processing the temperature data with reference to image data representative of the vascular wall morphology to provide an integrated graphical image output in which the temperature data is mapped onto a corresponding position on the image where that temperature data was detected.
