  • Publication number: 20150174410
    Abstract: Methods and devices for reducing ventricle filling volume are disclosed. In some embodiments, an electrical stimulator may be used to stimulate a patient's heart to reduce ventricle filling volume or even blood pressure. When the heart is stimulated in a consistent way to reduce blood pressure, the cardiovascular system may over time adapt to the stimulation and revert back to the higher blood pressure. In some embodiments, the stimulation pattern may be configured to be inconsistent such that the adaptation response of the heart is reduced or even prevented. In some embodiments, an electrical stimulator may be used to stimulate a patient's heart to cause at least a portion of an atrial contraction to occur while the atrioventricular valve is closed. Such an atrial contraction may deposit less blood into the corresponding ventricle than when the atrioventricular valve is opened throughout an atrial contraction.

  • Patent number: 8840658
    Abstract: The present invention provides an electrical block implant sized and shaped for securement at the perimeter of the pulmonary ostium of the left atrium. By utilizing various expandable ring designs and optional anchoring mechanisms, the present invention causes even, circular scarring around the perimeter of the pulmonary ostium, achieving reliable blocking of aberrant electrical signals responsible for atrial fibrillation.

  • Publication number: 20140052169
    Abstract: An apparatus and method of use are disclosed for treating, preventing and terminating arrhythmias. In particular, the apparatus is implantable within or on various tissues and structures and is used to prevent or block conduction of aberrant impulses. A variety of methods of the present invention may be used to attack arrhythmias by short-circuiting impulses, inducing fibrosis, ablating tissue or inducing inflammation. In addition, the device and methods may also be used to treat aneurysms. The device may also be used to treat hypertension, and to function as a blood pressure regulator.

  • Publication number: 20140046362
    Abstract: A method and apparatus for attaching tissue to bone in a shifted position without requiring surgical detachment of muscle or connective tissue joining the tissue layer to the bone layer. The skin layer is gently pulled in a non-surgical manner and a fastener of the invention is driven through the skin layer into the bone layer to effect a “skin tightening” procedure.

  • Patent number: 8428729
    Abstract: A method that electrically stimulates a heart muscle to alter the ejection profile of the heart, to control the mechanical function of the heart and reduce the observed blood pressure of the patient. The therapy may be invoked by an implantable blood pressure sensor associated with a pacemaker like device. In some cases, where a measured pretreatment blood pressure exceeds a treatment threshold, a patient's heart may be stimulated with an electrical stimulus timed relative to the patient's cardiac ejection cycle. This is done to cause dyssynchrony between at least two cardiac chambers or within a cardiac chamber, which alters the patient's cardiac ejection profile from a pretreatment cardiac ejection profile. This has the effect of reducing the patient's blood pressure from the measured pretreatment blood pressure.

  • Publication number: 20120221042
    Abstract: Methods and devices that treat the left atrial appendage by bringing the distal wall of the appendage to a position where the tissue of the wall blocks the ostium, thereby preventing blood from flowing into the appendage. The methods and devices are adapted to create a separation between the distal wall of the appendage and the adjacent pericardium such that the risk of rupturing the pericardium are minimized.
