Embodiment Construction

[0027] Many structural variations of MR compatible steerable sheaths and control handles according to the present invention are contemplated and are within the contemplated scope of the present invention. Those skilled in the art will appreciate that the exemplary control handle can be connected to other types of steerable sheaths. Additionally, those skilled in the art will appreciate that the exemplary steerable sheath can be combined with other control handles. Accordingly, for purposes of discussion and not limitation, an exemplary embodiment of an MR compatible steerable sheath and control handle will be described in detail below.

[0028] now refer to figure 1 , the control handle 10 according to the present invention includes such as figure 1 Housing 2 shown. The housing 2 includes a distal portion 12 , a grippable intermediate region 14 and a proximal end 16 . The distal portion 12 includes an aperture 18 through which the steerable sheath 100 can exit. The proxim...

Abstract

An MR compatible deflectable catheter and method of using the same is provided. The MR compatible deflectable catheter includes a steerable sheath having a tubular shaft. The tubular shaft receives first and second longitudinal movement wires at a distal end thereof. A control handle is coupled to a proximal end of the first and second longitudinal movement wires and causes longitudinal movement of the wires.

Description

technical field [0001] The present invention relates to steerable medical catheters, i.e. steerable sheaths for delivering tools (such as electrophysiology catheters, guide wires, balloon catheters, stents, instruments, etc.) Handle to steer the sheath. More specifically, the present invention relates to a sheath for safe use in a magnetic resonance environment and a family of handles for operating the sheath, since the materials used in the invention are compatible with strong electromagnetic fields. Background technique [0002] MRI (Magnetic Resonance Imaging) is already well known as a diagnostic imaging modality and is increasingly becoming known as an interventional imaging method. The main advantages of MRI over other imaging methods such as X-rays include superior soft tissue imaging and avoiding patient exposure to ionizing radiation produced by X-rays. The superior soft tissue imaging capabilities of MRI have provided great clinical advantages for diagnostic imag...
