Problems solved by technology

Changing these different catheters during the procedure can lead to inaccuracies or movement in the positioning and position of the distal tip relative to the tissue to be ablated and can also increase the time required to deliver the desired treatment
Not to mention the risk of complications due to the repeated insertion and withdrawal of instruments into and out of the incision site, these possible inaccuracies and prolonging the duration of a particular procedure itself put the patient undergoing the procedure at higher risk
Accordingly, it would be desirable to provide a single medical device that can provide ablation patterns of various shapes and continuities without the use of additional catheters or the like with a single geometric orientation, thus limiting the ability to provide multiple ablation patterns or treatment continuities for specific tissue regions. sexual ability

Embodiment Construction

[0012] The present invention advantageously provides a medical system capable of providing wounds or ablation segments of various shapes at specific tissue sites and also capable of ensuring the continuity of the ablation wound or pattern. Referring now to the drawings, wherein like reference numerals refer to like components, an embodiment of a medical system constructed in accordance with the principles of the present invention is described in figure 1 shown in and generally designated by the reference numeral "10". The medical system generally includes a control unit or console 12 coupled to a medical instrument 14 through an umbilical system 16 . Medical device 14 may be a medical probe, catheter, balloon catheter, and device that can be delivered or otherwise positioned through vasculature and / or in proximity to a tissue region to be treated. Specifically, medical device 14 may include a device operable to thermally treat selected tissue sites, including cardiac tissue. ...

Abstract

An intravascular catheter is provided, including a flexible elongate body; an expandable element positioned on the elongate body; a substantially linear thermal segment located distally of the expandable element; a first fluid flow path in fluid communication with the expandable element; and a second fluid flow path in fluid communication with the substantially linear thermal segment.

Description

technical field [0001] The present invention relates to methods and systems for tissue treatment, and more particularly to systems and methods for thermal ablation of cardiac tissue. Background of the invention [0002] Minimally invasive devices such as catheters are commonly used in surgical procedures, including those involving ablation, dilation, and the like. In certain instances, the ablation procedure may involve creating a series of interconnected or otherwise continuous lesions to electrically isolate tissue believed to be the source of the arrhythmia. During this procedure, the physician may employ several different catheters with various variations in the geometry and / or size of the ablation elements to produce the desired pattern and / or continuity of ablation. Each catheter may have a unique geometry to create a particular wound or pattern, and during a particular procedure, multiple catheters are sequentially removed and replaced to create the desired pattern o...
