Embodiment Construction

[0016] In the figure, reference numeral 10 generally indicates an embodiment of a catheter sheath for a mesh basket catheter, which is manufactured according to a process flow for manufacturing a mesh basket catheter as described below. The mesh basket catheter 10 is suitable for use as a three-dimensional survey catheter and as an ablation catheter for ablating a treatment area. Figure 1a with Figure 1b The distal end of this mesh basket catheter is shown. The catheter 10 includes a plurality of elongated electrical leads 12, each lead having one or more electrodes 18, 20 attached to the distal portion of the electrical lead. Each electrical wire 12 has a proximal part (at Figure 1a or Figure 1b Not shown in) and the distal portion 12a and the cavity extending from the proximal end to the distal end 12b. Will be for example made of such as Nitinol (Nitinol TM ) The shaped member 16 (not shown) of the shape memory wire is inserted into the cavity of the electrical wire 12. ...

Abstract

A catheter sheath for a basket catheter which includes a plurality of electrical leads each having a proximal end and a distal end and a lumen extending from the proximal end to the distal end. Each electrical lead includes a tubular member of non-conductive material, a plurality of electrical conductors extending from the proximal end to the distal end laid on the non-conductive tubular member, and an outer layer of non-conductive material applied over the electrical conductors to cover the conductors. The catheter sheath further includes one or more electrodes on a distal portion of each electrical lead in electrical communication with at least one of the plurality of electrical conductors through the outer layer. An elongate shape forming member is received in the lumen of each of the plurality of electrical leads. The shape forming member imparts an arched shape to the distal portion of each of the electrical leads so as to form a basket shape to a distal portion of the catheter sheath. The plurality of electrical leads are bundled together at their distal ends and proximal the distal arched portion of each electrical lead.

Description

Technical field [0001] This application mainly relates to a mesh basket catheter and a method for manufacturing the mesh basket catheter. Background technique [0002] Throughout the specification, any discussion of the prior art should in no way be regarded as an acknowledgement that the prior art is widely known or forms part of common general knowledge in the art. [0003] Electrophysiological catheters are commonly used in medical practice to examine and treat the heart. They can be inserted into the patient's cardiovascular system through small perforations in the skin. They can then extend through the veins into the heart, where the electrical activity of the heart is sensed. Some electrophysiological catheters may be able to treat the heart by ablating appropriate areas of the heart in the presence of certain types of abnormal electrical activity. [0004] Several different electrode designs have been developed to treat cardiac arrhythmias such as atrial flutter and atrial ...
