CATHETER ASSEMBLY AND ASSOCIATED METHOD
First Claim
1. A catheter assembly for use in an anatomy comprising:
- an elongated body having a proximal end and a distal end, and defining a lumen from the proximal end to the distal end;
at least one electrode coupled to the distal end that senses an electrical activity within the anatomy;
a core wire received within the lumen extending from the proximal end to the distal end, the core wire configured to move the distal end from a first configuration to a second configuration; and
a necked portion formed between the proximal end and the distal end to provide increased stiffness to the distal end of the body.

Abstract
A catheter assembly for use in an anatomy can include an elongated body, which can have a proximal end and a distal end. The body can also define a lumen from the proximal end to the distal end. The assembly can include at least one electrode, which can be coupled to the distal end to sense an electrical activity within the anatomy. The assembly can include a core wire, which can be received within the lumen from the proximal end to the distal end. The core wire can be configured to move the distal end from a first configuration to a second configuration. The assembly can also include a necked portion, which can be formed between the proximal end and the distal end to provide increased stiffness to the distal end of the body.

14. A catheter assembly for use in an anatomy comprising:
-
an elongated body having a proximal end, a distal end and a body diameter, and further defining a lumen from the proximal end to the distal end; a plurality of electrodes coupled to the distal end configured to sense an electrical activity within the anatomy; a core wire received within the lumen extending from the proximal end to the distal end, the core wire configured to move the distal end from a first configuration to a second configuration; and at least one necked portion formed between the proximal end and the distal end to provide increased stiffness to the distal end of the body wherein the at least one necked portion has a necked diameter smaller than the body diameter. - View Dependent Claims (15, 16)
