Abstract
Balloon catheters according to the present invention have surface contours with protrusions and grooves to make non-continuous lesions. There is a heating element inside the balloon. The balloon will be filled with a fluid before ablation to expand the balloon for tissue contact, and to transfer heating energy from the heating element to the tissue in contact with the balloon. Since the balloon surface has contours with grooves and protrusions, the tissue contact will not be continuous along the balloon surfaces, and therefore the ablation on the tissue will not be continuous. The energy transmitter can be ultrasound transducer, electrical resistant heater, and microwave antenna.

The fluid-filled ball conduit in electrical heating the inside has been used to heating and has transformed uterine cancer cell.And the ball conduit of ultrasonic heating has been used for heating transformation heart tissue.These ball conduits have following advantage: the heat tissue and do not cause tissue to burn equably on the ball surface has good the contact with tissue, and can side by side heat in large area and transform tissue in body cavity.But these ball conduits also are not used in heating and transform sphincter to shrink body cavity.One of its reason is exactly that these ball conduits tend to cause continuous transformation tissue, particularly continuously around body cavity one to transforming tissue, this is undesirable.
Summary of the invention
Thereby the objective of the invention is to create the ball conduit that the large tracts of land tissue of can discontinuous heating transforming body cavity makes the body cavity contraction.
Technical scheme of the present invention is as follows:
According to the present invention, provide a kind of the heating to transform ball conduit that bodily cavity tissue uses it has a heating element heater at the front end of conduit, this heating element heater with a ball cover, ball the inside can be filled with so that ball expand and heat passed to the fluid of ball, transform the tissue that contacts with ball with heating, it is characterized in that: there is surface texture on the ball surface, and described surface texture has projection and the recess between described projection, so that discontinuous to the transformation of tissue.
Preferably, the projection of ball surface texture and recess are microscler.
Preferably, microscler projection and recess are parallel to the interior catheter shaft of ball.
Preferably, microscler projection and recess are not parallel to the interior catheter shaft of ball.
Preferably, projection and recessed part are equally distributed.
Preferably, projection and recessed part are irregular distributions.
Preferably, heating element heater is a resistance heater.
Preferably, heating element heater is a microwave antenna.
Preferably, heating element heater is a ultrasound source, therefrom ultrasound wave with heat by in the tissue that the fluid in the ball passes to ball contacts.
Preferably, ball has at least a thermal resistance to come the thermometric degree above being installed in.
Preferably, be used to heat the sphincter of the bodily cavity tissue that transforms nose, esophagus, cardia, stomach, pyloric ostium, intestinal, anus, urinary tract and opening of bladder.
There is the convex-concave surface structure on the ball surface of ball conduit of the present invention, and promptly the outstanding some places of some places are recessed is used for discontinuous heating and transforms tissue.A heating element heater is arranged in the inside of ball.Before heating, come the filling ball that ball is contacted with endoceliac tissue with a kind of fluid, and heat energy is gone from the tissue that thermal element is transferred to ball contacts.Because there is the convex-concave surface structure on the ball surface, the ball surface is discontinuous with contacting of tissue, also is discontinuous so be heated organizing of transformation.
This ball conduit has not have to burn does not have the advantage of boring a hole, and a lot of tissue engineered can side by side carrying out on the large tracts of land very much, and distance can be controlled between the tissue of being transformed simultaneously.
Description of drawings

Fig. 2 illustrates the shape and the distribution of a kind of convex-concave surface structure of ball, protrudes with recessed place all to be microscler and to be parallel to the axle center of conduit.
Fig. 3 illustrates the convex-concave surface structure of the ball of another kind of form, and convexo-concave shape is irregular, and their distribution is parallel and perpendicular to the conduit axle center.
Fig. 4 is illustrated in the outstanding irregular distributional pattern of garden shape on the ball surface.
The specific embodiment
As shown in Figure 1, there is a heating element heater 13 to be contained in to be used on the conduit heating to transform tissue at the front end of ball conduit.This heating element heater is being covered by a ball 10.Can make ball splash bloated and contraction by in conduit 14, adding or discharging a kind of fluid.Ball is splashed to expand and can be made it to contact with organizing, and ball shrinks to be convenient to conduit be inserted or transfer in body cavity.Heat imports the tissue that contacts with the ball surface from heating element heater by fluid the ball and ball.Mainly be that organizing of contacting with the ball surface just can make the heating transformation good because of conduction of heat.
Main feature of the present invention is that the ball of conduit has surperficial convex-concave structure, and some places protrude 11, and some places are recessed 12, are used for causing discontinuous tissue engineered.Have only the ground that protrudes on the ball can excellent contact be arranged to guarantee good conduction of heat and heat tissue transformation with tissue just now.Place recessed on the ball just can not contact with tissue, does not therefore just have good conduction of heat to tissue, also just not to tissue heating transformation.Position recessed on the ball will be by gas or intravital fluid-filled, and therefore, the heat in the ball can not directly be passed to the tissue relative with this position and get on.Thus, this ball conduit will cause various discrete tissue heating to transform round body cavity.
In order to treat anal incontinence, the urinary tract incontinence, regurgitation acid and obesity are necessary the tissue of body cavity is carried out discontinuous heating transformation, thereby body cavity is shunk and do not influence the normal contraction of body cavity and the ability of loosening.Discontinuous heat tissue transformation can shrink body cavity and reduce body cavity loosen frequency in, keep normal body cavity and loosen and contractile function by remaining on the intermediary tissue of not transforming of organizing of transformation.And on the other hand, successive tissue heating is transformed, and particularly centers on the tissue engineered of body cavity girth, can for good and all damage loosening normally and contractile function of tissue.
