Embodiment Construction

[0054] In the following, means for supporting temperature changes in tissue are described. More particularly, the device is suitable for performing cryoablation in human or animal tissue and includes a treatment monitoring arrangement and / or an adhesion management arrangement.

[0055] Turning now first to the disposal monitoring arrangement, this is in figure 1 As schematically shown in , the treatment monitoring arrangement is at least partially integrated into the cryoablation probe CAA. The probe CAA is arranged to administer cryoablation at a lesion in human or animal tissue.

[0056] For more details refer to figure 1 , shows an elongated, generally cylindrical probe body P (shown in partial cutaway side view) terminating at one end in a metal handling head TH. At the other end of the elongated probe body P there is a connector module CON.

[0057] The connector module CON comprises a first connector CON1 arranged to connect the probe to the cryogenic source CS. The...

Abstract

A cryo-ablation systems with a probe body (P) having a treatment head (TH) with a tip portion (TP) for contacting tissue at a region of contact and configured for imparting a temperature change to thetissue at said region of contact. A plurality of electrodes (Ej) are arranged spaced apart from said tip portion and around said tip portion, configured to measure an electrical property of the tissue in a neighborhood around said region of contact. Adhesion management means are also envisaged.

Description

technical field [0001] The invention relates to a device for supporting temperature changing operations in tissue, a method for supporting temperature changing operations in tissue, a computer program element and a computer readable medium. Background technique [0002] Cervical cancer is the most common cause of cancer death among women in relatively low resource settings such as refugee camps or countries with relatively low GDP per capita. [0003] At this point, downstaging efforts (i.e. cancer reduction measures) are seen in many developing countries (e.g. India, China) and are expected to be driven by large-scale screening by national health ministries or UN health agencies. It is planned to increase in the future. In particular, level 1 evidence (i.e., evidence from at least one appropriately designed randomized controlled trial) showed a benefit of relatively simple point-to-point management ("see and treat" strategy) to achieve downstaging and thus reduce risk of c...
