[Application of plasma-mediated cold ablation in otorhinolaryngology].

Vestnik otorinolaringologii, 2009
A total of 226 surgical operations were made with a Coblator II plasma surgery system including tonsillectomy, uvulopalatoplasty, reduction of inferior turbinates, and removal of soft palate neoplasm. This method permitted to avoid intraoperative bleeding and reduce to 2% the frequency of hemorrhage in the postoperative period.

Radiofrequency Ablation of Renal Transitional Cell Carcinoma with Protective Cold Saline Infusion

Journal of Vascular and Interventional Radiology, 2003
Radiofrequency (RF) ablation is a feasible option for treatment of renal tumors when definitive tumor resection is not performed. Renal hilar and ureteral masses are generally more difficult than peripheral renal tumors to approach with RF ablation because of the higher associated risks of injury to the hilar vessels and the collecting system.

Generation of cold low divergent atomic beam of indium by laser ablation

Review of Scientific Instruments, 2005
The formation of low-energy (below 100m∕s), low divergence (without any collimation optics) pulsed indium atomic beam via ablation of thin film by direct illumination (unfocused) from the rear side with second harmonic of Q-switched Nd:YAG laser under high vacuum (∼10−5Torr) is reported. Angular divergence of an ablated indium beam was measured for the

Confinement of a plasma column by ablation fronts from cold gas plugs

The Physics of Fluids, 1979
A cylindrical plasma column of about 1–2 eV temperature and ne ≈ 1016 cm−3 is confined and compressed in the axial direction by an ablation front supported with a specific power in the range W/ρ1 = 108–5×109 W cm/g. Pressure and particle velocity are measured as a function of W/ρ1 and compared with model predictions.

ABLATION TESTING IN HOT AND COLD COAXIAL JETS. PHASE 1: COLD FLOW FEASIBILITY TESTS

1970
Abstract : An investigation was conducted to determine the feasibility of extending the capability of ablation test facilities by surrounding the high enthalpy flow with a coaxial cold air jet. The investigation included both analytical and cold flow experimental studies.

[Radiofrequency current or cryoballoon for ablation of atrial fibrillation? : Hot or cold?]

Herz, 2018
Atrial fibrillation (AF) is the most common form of cardiac arrhythmia. The aim of therapy in symptomatic patients is the establishment of a stable sinus rhythm (SR). Catheter ablation with isolation of the pulmonary veins is the essential component of all forms of ablation therapy and provides the most effective treatment option.

Evolution of Frost Penetration and Ablation in the Surrounding Rock of Cold Region Tunnels

2018
Taking Jiangluling tunnel as an example, a numerical model for investigating the evolution of the frost penetration and ablation in the surrounding rock of cold region tunnels is presented based on the governing equations of the coupling problem of temperature and air flow fields in cold region tunnels.

Hot vs cold knife for endoscopic ablation of posterior urethral valves

Journal of Pediatric Urology
Introduction:Posterior urethral valves (PUV) are the most frequent cause of congenital lower urinary tract obstruction in males. Despite early surgical ablation, up to 22% of patients develop chronic kidney disease and 11% progress to end-stage renal disease.
