摘要:
Improved devices, systems, and methods treatment of patients can be used to help mitigate injury to the kidneys by applying cyclical mechanical pressure energy at low intensities. The energy often be selectively directed from non-invasive transducers disposed outside the patients. The energy will typically comprise low frequency ultrasound energy, shock wave energy, or the like, and may induce the generation and/or release of nitric oxide, thereby enhancing perfusion and ameliorating tissue damage. Superimposed micro and macro duty cycles may help avoid thermal and other injury to tissues of the patient during treatment. Bilateral treatments are facilitated by a support structure that orients at least one transducer toward each kidney.

Systems, methods, and interfaces are described herein for noninvasively determining whether a patient can benefit from cardiac resynchronization therapy. One exemplary method involves delivering ultrasonic energy to cardiac tissue. In response to delivering ultrasonic energy to the cardiac tissue, receiving, with a processing unit, a torso-surface potential signal from each of a plurality of electrodes distributed on a torso of a patient. For at least a subset of the plurality of electrodes, calculating, with the processing unit, a torso-surface activation time based on the signal sensed from the electrode. Presenting, by the processing unit, to a user, an indication of a degree of dyssynchrony of the torso-surface activation times via a display.
摘要:
A system and method are disclosed for stimulating activation of heat shock proteins and facilitating protein repair in cells and tissues in order to take advantage of the remediative and restorative nature of the increased heat shock protein activation or production and the facilitation of protein repair, while not damaging the cells and tissues. This is accomplished by treating a specified target area with an ultrasound or electromagnetic radiation source which is pulsed and applied or focused to one or more small areas in order to achieve the necessary temperature rise or sufficiently stress the cells and tissue to stimulate heat shock protein production or activation and facilitate protein repair, while allowing the temperature to decay sufficiently quickly so as not to damage or destroy the treated tissue.
摘要:
The present invention relies on a controller-transmitter device to deliver ultrasound energy into cardiac tissue in order to directly improve cardiac function and/or to energize one or more implanted receiver-stimulator devices that transduce the ultrasound energy to electrical energy to perform excitatory and/or non-excitatory treatments for heart failure. The acoustic energy can be applied as a single burst or as multiple bursts.

Described herein are methods and apparatus for detecting stones by ultrasound, in which the ultrasound reflections from a stone are preferentially selected and accentuated relative to the ultrasound reflections from blood or tissue. Also described herein are methods and apparatus for applying pushing ultrasound to in vivo stones or other objects, to facilitate the removal of such in vivo objects.
摘要:
An ultrasonic probe includes a first coupled vibration member and a second coupled vibration member each of which extends along a longitudinal axis between a first anti-node position of an ultrasonic vibration and a second anti-node position of the ultrasonic vibration located to a distal direction side of the first anti-node position. The second coupled vibration member vibrates in the same mode as the first coupled vibration member. A first groove of the first coupled vibration member and a second groove of the second coupled vibration member cooperate with each other and thereby form at least a part of a passage inside a multiple-members vibrating portion formed by the first coupled vibration member and the second coupled vibration member.

The invention includes: a new composition of matter (a composite comprising a naturally occurring in vivo cornea in an in situ eye together with at least one volume of vitrified non-naturally occurring corneal stromal tissue formed within the naturally occurring corneal stromal tissue) wherein the vitrified tissue is modified in structure and properties from its naturally occurring condition into a non-naturally occurring glass-like condition with modifications including but not limited to increased elastic modulus; methods for producing and using the new composition of matter for modifying corneal structure and properties, including but not limited to corneal optical aberrations; wound closure adhesion and transplant adhesion; and a photo vitrification system for producing the new composition of matter comprising at least one photon source with controllable treatment parameters. A reverse template can be added to corneal vitrification systems to increase vitrification and modifications of structure and properties.
