Patent number: 7357815Abstract: Tissue shaping methods and devices are provided. The devices can be adjusted within the body of a patient in a less invasive or non-invasive manner, such as by applying energy percutaneously or external to the patient's body. In one example, the device is positioned within the coronary sinus of the patient so as to effect changes in at least one dimension of the mitral valve annulus. The device may also advantageously include a shape memory material that is responsive to changes in temperature and/or exposure to a magnetic field. In one example, the shape memory material is responsive to energy, such as electromagnetic or acoustic energy, applied from an energy source located outside the coronary sinus. A material having enhanced absorption characteristics with respect to the desired heating energy may also be used to facilitate heating and adjustment of the tissue shaping device.Type: GrantFiled: May 6, 2005Date of Patent: April 15, 2008Assignee: Micardia CorporationInventors: Emanuel Shaoulian, Shahram Moaddeb, Samuel M.

Publication number: 20080051840Abstract: Systems, methods and devices are provided for improving the hemodynamic efficiency of a patient's heart by implanting one or more reinforcement elements on or with the heart and providing electrical stimulation to the heart. The reinforcement elements may include magnetic and/or shape memory material and are configured to reshape the heart so as to boost the heart's mechanical energy during a response to the electrical stimulation. In some embodiments, at least one reinforcement element includes an electrode configured to sense electrocardiogram signals within the heart. An electrical stimulation device such as an implantable or external pacemaker/defibrillator may be configured to control delivery of electrical pulses to the heart based on the sensed electrocardiogram signals.

Publication number: 20080039681Abstract: Systems, methods and devices are provided for treating heart failure patients suffering from various levels of heart dilation. Such heart dilation is treated by reshaping the heart anatomy with the use of shape memory elements. Such reshaping changes the geometry of portions of the heart, particularly the right or left ventricles, to increase contractibility of the ventricles thereby increasing the stroke volume which in turn increases the cardiac output of the heart. The shape memory elements have an original shape and at least one memory shape. The elements are implanted within the heart tissue or attached externally and/or internally to a surface of the heart when in the original shape. The elements are then activated to transition from the original shape to one of the at least one memory shapes. Transitioning of the elements cause the associated heart tissue areas to readjust position, such as to decrease the width of the ventricles.Type: ApplicationFiled: October 22, 2007Publication date: February 14, 2008Applicant: MICARDIA CORPORATIONInventors: Shahram Moaddeb, Samuel Shaolian, Emanuel Shaoulian, Richard Rhee, Steven Anderson

Publication number: 20070055368Abstract: Methods and devices are provided for support of a body structure. The devices can be adjusted within the body of a patient in a minimally invasive or non-invasive manner, such as by applying energy percutaneously or external to the patient's body. The energy may include, for example, acoustic energy, radio frequency energy, light energy and magnetic energy. Thus, as the body structure changes size and/or shape, the size and/or shape of the annuloplasty rings can be adjusted to provide continued reinforcement. In certain embodiments, the devices comprise a shape memory material, and further include a body member and an insert member. The body member has a circumference and a slot that extends at least partially along the circumference of the body. The insert member extends at least partially along the circumference of the body.Type: ApplicationFiled: August 31, 2006Publication date: March 8, 2007Inventors: Richard Rhee, Emanuel Shaoulian, Shahram Moaddeb, Samuel Shaolian

Publication number: 20060252983Abstract: Implants for treatment of obesity may be placed within the stomach and/or esophagus or around the outside surface of the stomach and/or esophagus. The implants comprise at least a portion constructed of a shape memory material. The implants are thus adapted to be implanted in a deformed shape, and then to be transformed through the application of activation energy into a memorized shape. The shape and/or size transformation induces a change in shape of the stomach and/or esophagus, thus altering the normal digestive path of food entering the patient's gastrointestinal tract.Type: ApplicationFiled: February 10, 2006Publication date: November 9, 2006Inventors: Nicholas Lembo, Shawn Moaddeb, Emanuel Shaoulian, Samuel Shaolian, Michael Henson

Publication number: 20060241746Abstract: Methods and devices for reshaping or reforming tissue, such as a mitral valve of a heart, are described. An implant includes a generally flexible body and a plurality of magnetic portions such that the magnetic portions interact to cause a change in the shape of the implant, which, in turn, effects a change in shape of the subject tissue. In one example, at least one implant is positioned within a coronary sinus to affect the shape of the mitral valve annulus. The implant may further include fixation mechanisms for securing the implant within a vessel and may provide for removability after desired deformation of the subject tissue has taken place.Type: ApplicationFiled: April 21, 2005Publication date: October 26, 2006Inventors: Emanuel Shaoulian, Shahram Moaddeb

Publication number: 20060015178Abstract: Tissue shaping methods and devices are provided for reinforcing and/or remodeling heart valves. In certain embodiments, magnetic tissue shaping devices are implanted in tissue adjacent heart valve leaflets. The devices are mutually attractive or repulsive so as to remodel the heart tissue and improve heart valve function. In certain other embodiments, one or more tissue shaping devices including shape memory material are implanted in a patient's body within or on tissue adjacent a heart valve leaflet. The shape memory material can be activated within the patient in a less invasive or non-invasive manner, such as by applying energy percutaneously or external to the patient's body. The shape memory tissue shaping devices are implanted in a first configuration and then activated to remember a second configuration that displaces tissue so as to remodel the heart valve geometry and improve heart valve function.Type: ApplicationFiled: July 14, 2005Publication date: January 19, 2006Inventors: Shahram Moaddeb, Emanuel Shaoulian, Samuel Shaolian, Michael Henson, Richard Rhee, Steven Anderson

Publication number: 20060015003Abstract: Systems, methods and devices are provided for treating heart failure patients suffering from various levels of heart dilation. Heart dilation treated by reshaping the heart anatomy with the use of magnetic forces. Such reshaping changes the geometry of portions of the heart, particularly the right or left ventricles, to increase contractibility of the ventricles thereby increasing the stroke volume which in turn increases the cardiac output of the heart. The magnetic forces are applied with the use of one or more magnetic elements which are implanted within the heart tissue or attached externally and/or internally to a surface of the heart. The various charges of the magnetic forces interact causing the associated heart tissue areas to readjust position, such as to decrease the width of the ventricles. Such repositioning is maintained over time by the force of the magnetic elements, allowing the damaging effects of heart dilation to slow in progression or reverse.Type: ApplicationFiled: May 31, 2005Publication date: January 19, 2006Applicant: MiCardia CorporationInventors: Shahram Moaddes, Samuel Shaolian, Emanuel Shaoulian, Richard Rhee, Steven Anderson
