Publication number: 20090248148Abstract: Systems and methods treat a heart valve using a magnetically adjustable annuloplasty ring attached to or near a cardiac valve annulus. A changing magnetic field may be used to selectively increase or decrease a circumference of, or otherwise modify the shape of, the implanted annuloplasty ring. The adjustable annuloplasty ring includes a tubular body member, one or more adjustable members, and an internal magnet within the tubular body member. The tubular body member and the one or more adjustable members form a ring shape. The internal magnet is configured to rotate in response to a rotating external magnetic field. The internal magnet is coupled to the one or more adjustable members to change a dimension of the ring shape as the internal magnet rotates. A system for treating a heart valve may include an external adjustment device having one or more external magnets to generate the rotating external magnetic field.Type: ApplicationFiled: March 25, 2009Publication date: October 1, 2009Applicant: ELLIPSE TECHNOLOGIES, INC.Inventors: Samuel M.

Patent number: 7594887Abstract: 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: GrantFiled: October 22, 2007Date of Patent: September 29, 2009Assignee: MiCardia CorporationInventors: Shahram Moaddeb, Samuel M. Shaolian, Emanuel Shaoulian, Richard Rhee, Steven C. Anderson

Patent number: 7582106Abstract: A subcutaneously assembled in place orthopedic construct is provided, such as for fixation of the spine. The construct includes a first bar and a second bar for attachment to the spine. A crossbar connects the first and second bar, to provide additional structural support. Each of the first bar, the second bar, and the crossbar may be inserted in a minimally invasive procedure, and constructed in place to form the orthopedic device. Each of the first bar, second bar, and crossbar may comprise an inflatable container, adapted for inflation with a hardenable media and cured in place. Methods and delivery structures are also disclosed.Type: GrantFiled: October 20, 2003Date of Patent: September 1, 2009Inventors: George P. Teitelbaum, Samuel M. Shaolian, To V. Pham, Thanh Van Nguyen

Publication number: 20090088838Abstract: An adjustable annuloplasty device is described. In some embodiments, the device includes a body member having a surface that conforms at least partially to a cardiac valve annulus. The body member comprises a shape-memory member that transforms from a first configuration to a second configuration in response to an applied energy. In some embodiments, the device further includes a first electrode assembly, coupled to the shape-memory member, that transfers energy to the shape-memory member, and a second electrode assembly, coupled to the shape-memory member, that transfers at least a portion of the energy away from the shape-memory member.Type: ApplicationFiled: March 28, 2008Publication date: April 2, 2009Inventors: Samuel M. Shaolian, Le Le, Jesus Flores, Jason Tran

Patent number: 7510577Abstract: 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 include a body member including a ferromagnetic shape memory material. The body member has a first size of a dimension in a first configuration and a second size of the dimension in a second configuration. The body member is configured to be implanted into a heart so as to reinforce a cardiac valve annulus in the first configuration.Type: GrantFiled: May 6, 2005Date of Patent: March 31, 2009Assignee: MiCardia CorporationInventors: Shahram Moaddeb, Emanuel Shaoulian, Samuel M.

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: July 21, 2008Publication date: November 27, 2008Applicant: MICARDIA CORPORATIONInventors: Shahram Moaddeb, Samuel M.

Publication number: 20080004692Abstract: Methods and devices are provided for providing a protective framework for treating an aneurysm with embolic coils and preventing mitigation of the embolic coils from the aneurysm. A dynamically remodelable stent having a first and a second configuration is delivered into the blood vessel patient, such as a human or other animal, and positioned adjacent an ostium of an aneurysm while in the first, linear configuration. The dynamically remodelable stent may then be activated to assume a second, expanded configuration and thereby provide a protective framework spanning the neck of the aneurysm during and after delivery of embolic devices, such as embolic coils, to the aneurysm. The stent can be activated 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.Type: ApplicationFiled: June 28, 2006Publication date: January 3, 2008Inventors: Michael R.
