ABSTRACT:

FIELD OF THE INVENTION
This invention relates to an ultrasound medical device. Noninvasive medical procedures reduce the risk of surgery by introducing medical devices to a body cavity through small incisions or body orifices. The devices are carefully designed so that they may be controlled from the proximal end remaining outside the body to carry out the requirement treatment at the desired location inside the body.
SUMMARY OF THE INVENTION
In one aspect, the invention features a medical device having at least a portion (e.g., an elongated wire-form or draw-form wire) for use within the body. The portion includes an extended metal outer member having an exposed outer surface and a core within the outer member formed of a metal different than the metal of the outer member. The core is secured within and substantially enclosed by the outer member. The portion is in the form of an ultrasonic probe. In embodiments, for example, the probe is an elastic probe having a titanium core and nitinol outer member. The outer member and the core are constructed of materials of substantially different acoustic impedance. The acoustic energy is provided by axial excitation.
The invention features wires (e.g., elongated wire-forms or draw-form wires) that can be used for conducting ultrasound energy. These wires achieve optimum properties by creating a multiple material coaxial construction. For example, in a particular embodiment it is desirable to have an elastic core (nitinol) for conducting axial vibrations (sonic or ultrasonic) and a thin stiff cladding (stainless steel) in order to minimize traverse vibrations which result in loss of energy.
The term “metal” as used herein includes electropositive chemical elements characterized by ductility, malleability, luster, and conductivity of heat and electricity, which can replace the hydrogen of an acid and forms bases with the hydroxyl radical and including mixtures including these elements and alloys. Many examples are given below.
Further aspects feature and advantages follow.
