Ablation systems and methods detect and address distortion caused by a variety of factors. A method includes measuring a temperature curve at target tissue; applying ablation energy to the target tissue; determining a peak temperature on the temperature curve; if the peak temperature is greater than the predetermined peak temperature, determining a time at which the temperature curve crosses to a lower temperature; and if the determined time is greater than a predetermined time, generating a message indicating that the target tissue was successfully ablated. Another method includes determining a distance between a remote temperature probe and an ablation probe, applying ablation energy to target tissue, measuring temperature at the remote temperature probe, estimating ablation size based on the determined distance and the temperature measured by the remote temperature probe, and determining whether the target tissue is successfully ablated based on the estimated ablation size.

A cryoprobe having a working tip formed of two coaxial flexible internal and external tubular lines, wherein the cross-section diameter of the internal line is substantially smaller than the cross-section diameter of the external line, and the length is slightly smaller than the length of the external line. The external line ends with a top closing the working tip of the cryoprobe, while the end of the internal line is open, and there are openings evenly distributed across the circumference on at least half of the section of the internal line. On the section from the handle to the end located under the top, a resistance wire is spirally wound on the internal line, wherein the distance between the wall of the external line and the wall of the internal line is larger than the diameter of the resistance wire. On the external line, no further from the top located on the top of the working tip than ⅓ of the length thereof, there is a temperature sensor connected to the handle by a power line. External and internal lines corresponding to the external and internal lines come out from the working tip outside the handle, wherein the external and internal lines together with the harness of power lines and, insulated with an insulating hose, are connected from the handle to the unit supplying air and liquid nitrogen at low pressure of up to 0.5 bars using a pump system.

The present disclosure relates to a surgical tool for cutting and hemostasis of biological tissues. The surgical tool includes a hollow blade comprising a cutting implement residing within a hollow cavity configured to provide high-pressure steam through an apical surface. The cutting implement can operate independently or in cooperation with the provided high-pressure steam. The surgical tool of the present disclosure applies a directionally-controlled, high-pressure steam flow to a tissue region of interest. A control unit provides temperature-controlled steam at a flow-rate determined in accordance with tissue type and intended procedure.

An ablation probe having a separable outer sleeve and a freezing function, comprising: an inner probe (101, 201, 301, 401), an outer sleeve (102, 202, 302, 402), and a handle (105, 205, 305, 405).

The slide of the outer sleeve (102, 202, 302, 402) on the surface of the inner probe (101, 201, 301, 401) can change the size and distribution of the ablation area of the inner probe (101, 201, 301, 401); the separable structure can form a channel between the outside of the body and the target area of treatment by means of the outer sleeve (102, 202, 302, 402) for biopsy, drug delivery, and hemostasis; the separable structure can be designed into a non-reusable structure for one-time use only to improve the safe usage of the ablation probe.

A method in which a nerve associated with a spasticity in a limb of a patient may be identified. The cryogenic cooling needle may be inserted through a skin surface. The cryogenic cooling needle may be positioned to a target tissue such that the distal end of the cryogenic cooling needle is proximate to the nerve by bending the needle, wherein the needle has varying stiffness at a proximal portion and a distal portion. A treatment cycle may be delivered to a target tissue proximate to the nerve, the treatment cycle may comprise a cooling phase wherein cooling fluid flows into the lumen so that liquid from the cooling fluid flow vaporizes within the lumen to provide cooling to the nerve so as to treat spasticity.

In a treatment system, an energy treatment instrument includes a pair of grasping pieces. An energy output source outputs electric energy to the energy treatment instrument, thereby applying treatment energy to a blood vessel grasped between the grasping pieces. A measurement section measures a blood pressure at a site related to the grasped blood vessel. A processor controls output of the electric energy from the energy output source based on a measurement result obtained by the measurement section, and thereby switches an actuation state of the energy treatment instrument between a first mode for coagulating the blood vessel and a second mode for coagulating the blood vessel target that is different from the first mode.
