Method and apparatus for increasing blood flow through an obstructed blood vessel
A method of increasing blood flow through an obstructed blood vessel includes providing an expandable member substantially made of a mesh having a plurality of interstices. The expandable member has a proximal member end and a distal member end spaced longitudinally apart by a tubular member body. The expandable member is substantially closed at the distal member end. The expandable member is inserted into the blood vessel. The expandable member is positioned within the blood vessel with the proximal member end upstream of the distal member end and the member body located radially adjacent at least a portion of an obstruction. The expandable member is expanded to bring at least a portion of the member body into contact with the obstruction. An outward radial force is exerted on the obstruction to dislodge at least one fragment from the obstruction and to enhance blood flow through the blood vessel past the obstruction. The at least one fragment is passed through at least one interstice of the member body in the radial direction. The at least one fragment is selectively retained within the expandable member. An apparatus for increasing blood flow through an obstructed blood vessel is also provided.

Systems and methods for electrosurgical treatment of fasciitis
InactiveUS20060189971A1Minimize and completely eliminate and damageExpand field of viewStentsHeart valvesFasciitisDamages tissue
Systems, apparatus, and methods are provided for promoting blood flow to a target tissue. In one aspect, the invention involves canalizing or boring channels, divots, trenches or holes through an avascular connective tissue, or through a tissue having sparse vascularity, such as a tendon or a meniscus, in order to increase blood flow within the tissue. In one method, an active electrode is positioned in close proximity to a target site on a tendon, and a high frequency voltage difference is applied between the active electrode and a return electrode to selectively ablate tendon tissue at the target site, thereby forming a channel or void in the tendon. The active electrode(s) may be moved relative to the tendon during, or after, the application of electrical energy to damage or sculpt a void within the tendon, such as a hole, channel, crater, or the like. In another aspect of the invention, an electrosurgical probe is used to elicit a wound healing response in a target tissue, such as an injured tendon, in order to stimulate vascularization of the target tissue. The present invention may also be used for vascularization of a torn or damaged tissue in conjunction with a surgical repair procedure.

Embodiments of the invention include a method and a device for increasing blood flow and controlling the temperature of a mammal by applying a desired pressure to extremities of a mammal. The device generally includes one or more collapsible and pliant body elements, capable of expanding from a first volume into an expanded second volume so the device can receive a portion of an extremity of the mammal therein and then be reduced from the expanded second volume into a pressurized third volume to conformably enclose the portion of the extremity. One or more thermal exchange units can be positioned in the one or more collapsible and pliant body elements. Accordingly, the temperature of the extremity of a mammal can be regulated by providing a heated or cooled fluid medium or electric thermal energy to the one or more thermal exchange units. Next, by evacuating the region in which the extremity is enclosed the contact surface area between the extremity of a mammal and the one or more thermal exchange units is increased, due to the external atmospheric pressure acting on the pliant body elements against the skin of the extremity of the mammal. The application of pressure assures that sufficient contact and thermal heat transfer (heating or cooling) is provided to the extremity of the mammal.

One method for diagnosing a cardiovascular-related condition in a breathing person comprises interfacing a valve system to the person's airway. The valve system is configured to decrease or prevent respiratory gas flow to the person's lungs during at least a portion of an inhalation event. The person is permitted to inhale and exhale through the valve system. During inhalation, the valve system functions to produce a vacuum within the thorax to increase blood flow back to the right heart of the person, thereby increasing blood circulation and blood pressure. Further, at least one physiological parameter is measured while the person inhales and exhales through the valve system. The measured parameter is evaluated to diagnose a cardiovascular condition.

Endoscopic arterial pumps for treatment of cardiac insufficiency and venous pumps for right-sided cardiac support
Methods for using blood pumps to treat heart failure are disclosed. The pump is mounted on an interior of a stent, and the stent is releasably mounted on a distal end of a catheter. The distal end of the catheter is inserted into a peripheral artery and advanced to position at a region of interest within the descending aorta, the ascending aorta, or the left ventricle. The stent and the pump are released from the catheter, and the pump is activated to increase blood flow downstream of the pump. The pump can also be positioned in the vena cava or used to treat right-sided heart failure following the insertion of an LVAD, or to improve venous return in patients with varicose veins. Non-stent pumps are described for insertion between the pulmonary vein and aorta, and between the vena cava and pulmonary artery designed for use during cardiac surgery.

Cpr devices and methods utilizing a continuous supply of respiratory gases
InactiveUS20070221222A1Increase magnitudeExtended durationTracheal tubesOperating means/releasing devices for valvesCardiorespiratory arrestBreathing gas
A method for increasing circulation and providing oxygen to a patient in cardiac arrest includes the step of coupling an interface to the patient's airway, the interface providing access to the patient's respiratory system. A valve system is operably attached to the interface. Oxygen is delivered through the interface a rate of between about 1.0 to about 10.0 L / min to provide a continuous supply of oxygen to the patient. While supplying the oxygen, a body structure of the patient is manipulated to increase the magnitude and duration of the patient's negative intrathoracic pressure. During the manipulation, the valve system prevents additional respiratory gases from entering the lungs until a negative intrathoracic pressure level in the range from about −1 cm H2O to about −15 cm H2O, the valve system assisting in increasing the magnitude and duration of negative intrathoracic pressure thereby enhancing the amount of blood flow in the heart and lungs and lowering intracranial pressure, therein further increasing blood flow to the brain.
