摘要： A medical device assembly and method provides an ultrasound transducer mounted onto a catheter shaft. The ultrasound transducer is mounted such that there is a radial separation between the transducer and the underlying catheter shaft. The transducer is mounted on support structures which do not bridge the gap between the transducer and delivery member. The location of the support structures provides for an “airbacked” transducer that is very efficient and prevents heat build-up in the materials in contact therewith.

摘要： This invention is related to a tissue ablation system and method that treats atrial arrhythmia by ablating a circumferential region of tissue at a location where a pulmonary vein extends from an atrium. The system includes a circumferential ablation member with an ablation element and also includes a delivery assembly for delivering the ablation member to the location. The circumferential ablation member is generally adjustable between different configurations to allow both the delivery through a delivery sheath into the atrium and the ablative coupling between the ablation element and the circumferential region of tissue.

摘要： A medical balloon catheter assembly includes a balloon having a permeable region and a non-permeable region. The balloon is constructed at least in part from a fluid permeable tube such that the permeable region is formed from a porous material which allows a volume of pressurized fluid to pass from within a chamber formed by the balloon and into the permeable region sufficiently such that the fluid may be ablatively coupled to tissue engaged by the permeable region. The non-permeable region is adapted to substantially block the pressurized fluid from passing from within the chamber and outwardly from the balloon. The porous material may be a porous fluoropolymer, such as porous polytetrafluoroethylene, and the pores may be created by voids that are inherently formed between an interlocking node-fibril network that makes up the fluoropolymer. Such voids may be created according to one mode by expanding the fluoropolymer. The balloon may be formed such that the porous material extends along both the permeable and non-permeable regions. In one mode of this construction, the porous material is porous along the permeable region but is non-porous along the non-permeable region, such as for example by expanding only the permeable region in order to render sufficient voids in the node-fibril network to provide permeable pores in that section. The voids or pores in the porous material may also be provided along both permeable and non-permeable sections but are substantially blocked with an insulator material along the non-permeable section in order to prevent fluid from passing therethrough. The insulator material may be dip coated, deposited, or extruded with the porous material in order to fill the voids. The insulator material may in one mode be provided along the entire working length of the balloon and then selectively removed along the permeable section, or may be selectively exposed to only the non-permeable sections in order to fill the voids or pores there.

摘要： A medical device assembly and method provides an ultrasound transducer mounted onto a delivery member, such the elongate body of a catheter shaft, without a support structure bridging between a separation area between the transducer and the shaft. Mounting flanges are extend from either end of the transducer and are mounted at first and second locations along the catheter shaft such that the transducer is suspended over the catheter shaft between those mounting locations. The flanges may be connected by an intermediate member, with the transducer supported on either an outer surface or an inner surface of the intermediate member. The intermediate member may also provide a housing with an enclosed space that houses the transducer, wherein the flanges extend from the housing for mounting to the catheter shaft. In an overall tissue coupling system, a cylindrical ultrasound transducer are mounted onto a catheter shaft by use of such mounting flanges extending from the transducer's ends and such that the ultrasound transducer is enclosed within a balloon also provided on the catheter. The balloon is ideally adapted to engage a circumferential region of tissue where a pulmonary vein extends from an atrium such that the cylindrical ultrasound transducer is able to couple through the balloon inflation fluid and to the circumferential region of tissue surrounding the balloon for ablation. The transducer is substantially “airbacked” when mounted onto a delivery member according to the present assembly and method.
