1 Product Description 1.1 Intended Use The Galil Medical disposable Single-Point 1.5 Thermal Sensor™ and Multi-Point 1.5 Thermal Sensor™ devices are components used in conjunction with a Galil Medical Cryoablation System when performing cryoablative destruction of tissue, to aid the physician’s assessment that the Freezing/Thawing cycles meet the desired treatment protocol. NOTE: These instructions are applicable to both the Single-Point 1.5 Thermal Sensor (TS) and the Multi-Point 1.5 Thermal Sensor (MTS). Collectively, these sensors are referred to as TS/MTS. It is recommended that TS and/or MTS be inserted into strategic locations in the tissue prior to the procedure so the acquired temperature readings will provide useful information about the progress of the Freezing and Thawing processes. These realtime temperature readings can be used to monitor the temperature of the tissue being ablated and to monitor the temperature of tissue not intended to be ablated.
1.2 Technical Description Each TS/MTS has a sharp cutting tip, a shaft with circumferential marks, a color-coded handle, tubing, and an electrical connector. The shaft marks on the TS/MTS are shown in Fig 1, below. All components are illustrated in Fig 2.

Instructions for Use
8.2 TS/MTS Use 8.2.1
TS/MTS Handling and Insertion
• Correct insertion of thermal sensors into the target tissue is the responsibility of the physician. NOTE: Although TS/MTS have sharp tips, a small skin incision may be made at the point of TS/MTS insertion. • Always use two hands and support the TS/MTS mid-shaft with two fingers to eliminate the risk of bending. Do not insert the sensor into tissue while holding the handle with one hand only. • Insertion depth may be estimated using the marks on the shaft. Use image guidance as necessary to guide TS/MTS insertion and placement. • Use image guidance to verify that the TS/MTS is placed at the desired location prior to activating the cryoablation needles.
8.2.2
Notes for Monitoring Temperatures
• Select the TS/MTS sensor locations appropriate to monitor the target tissue temperature numerically and/or graphically during the cryoablation procedure. • Use data from the TS/MTS display to assess tissue temperatures in the tissue surrounding a TS/MTS. • See the respective User Manual for instructions on system controls available to manage TS/MTS displays.
8.3 TS/MTS Removal • Thaw thoroughly and stop all needle operation prior to removing a TS/MTS to minimize a risk of tissue injury. NOTE: Ensure the tissue temperature is above 0°C before removing the TS/MTS. It is preferable to remove the TS/MTS before the cryoablation needles, to allow further thawing should additional thawing be required. NOTE: Galil Medical's thermal sensors are specially designed with a three-facet, trocarlike tip to minimize bleeding. However, some bleeding may occur. In the event of bleeding, apply treatment in accordance with good clinical practice and the hospital's treatment protocol. For example, following TS/MTS removal, hold compression until hemostasis is achieved; if necessary place appropriate dressing on the insertion site.
