Device and method for regulating pressure in a heart chamber
A device for regulating blood pressure in a heart chamber is provided. The device includes a shunt positionable within a septum of the heart. The shunt is designed for enabling blood flow between a left heart chamber and a right heart chamber, wherein the flow rate capacity of the device is mostly a function of pressure in the left heart chamber.
Devices and methods for treating heart failure
A device for implanting into an atrial septum of a patient. In some embodiments, the device has a core region to be disposed in an opening in the atrial septum; a distal retention region adapted to engage tissue on a left atrial side of the septal wall; a proximal retention region adapted to engage tissue on a right atrial side of the septal wall; and a retrieval region comprising a plurality of retrieval members, each retrieval member comprising a connector at a proximal end, the connector being adapted to connect to a delivery system. The device has a delivery configuration and a deployed configuration, the core region, distal retention region and proximal retention region each having a smaller diameter in the delivery configuration than in the deployed configuration, the retrieval member connectors being disposed proximal to and radially outward from the opening in the deployed configuration.
Treating dysfunctional cardiac tissue
Medical devices, systems, and methods reduce the distance between two points in tissue, often for treatment of congestive heart failure and often in a minimally invasive manner. An anchor is inserted along an insertion path through a first wall of the heart. An arm of the anchor is deployed and rotationally positioned according to a desired alignment. Application of tension to the anchor may draw the first and second walls of the heart into contact along a desired contour so as to effect a desired change in the geometry of the heart. Additional anchors may be inserted and aligned with the first anchor to close off a portion of a ventricle such that the ventricle is geometrically remodeled and disease progression is reversed, halted, and/or slowed.
Techniques for providing a replacement valve and transseptal communication
A method is provided, comprising: (1) making a transapical puncture into a left ventricle of the heart; (2) making a transseptal fenestration in the heart; (3) delivering a prosthetic valve via the transapical puncture and implanting the prosthetic valve at a mitral valve of the heart; and (4) subsequently to delivering the prosthetic valve and making the transseptal fenestration, closing the transapical puncture. Other embodiments are also described.
Techniques for providing a replacement valve and transseptal communication
During a medical procedure, a transseptal fenestration is made at a septum of the heart and a shunt is implanted into the transseptal fenestration. During the same medical procedure, a transapical puncture is made into a left ventricle of the heart. A prosthetic valve is delivered via the transapical puncture and implanted at a mitral valve of the heart. Subsequently to delivering the prosthetic valve and making the transseptal fenestration, the transapical puncture is closed. Other embodiments are also described.
MARTIAL ARTS GLOVES WITH ELECTRONIC SECORING SYSTEM
Martial arts gloves that allow for punch detection and electronic scoring using activation materials such as metals and sensors.
REVERSE VENTRICULAR REMODELING AND PAPILLARY MUSCLE APPROXIMATION
A cardiac tissue repositioning device comprises a first attachment member configured to be anchored to a first portion of cardiac tissue. The device further comprises a second attachment member configured to be anchored to a second portion of cardiac tissue. The device further comprises an adjustable body configured to be moveable between multiple positions and a locking mechanism configured to control movement of the adjustable body between the multiple positions.
CARDIAC TISSUE PENETRATING DEVICES, METHODS, AND SYSTEMS FOR TREATMENT OF CONGESTIVE HEART FAILURE AND OTHER CONDITIONS
According to one embodiment, a tissue penetrating device includes an elongate shaft having a proximal end, a distal end, and a lumen extending there between. A first needle is disposed within the lumen of the elongate shaft and is extendable therefrom between a first configuration and a second configuration. In the first configuration, the first needle is disposed within the elongate shaft's lumen and is substantially aligned with an axis of the lumen. In the second configuration, the first needle extends distally of the elongate shaft's distal end and bends away from the lumen's axis. A second needle is disposed within a lumen of the first needle and is extendable therefrom when the first needle is positioned in the first configuration and when the first needle is positioned in the second configuration. The second needle may be extended from the first needle to penetrate tissue of a patient.
Mitral valve annuloplasty systems and methods
Systems and methods for modifying a heart valve annulus in a minimally invasive surgical procedure. A helical anchor is provided, having a memory set to a coiled shape or state. The helical anchor is further configured to self-revert from a substantially straight state to the coiled state. The helical anchor is loaded within a needle that constrains the helical anchor to the substantially straight state. The needle is delivered to the valve annulus and inserted into tissue of the annulus. The helical anchor is then deployed from the needle (e.g., the needle is retracted from over the helical anchor). Once deployed, the helical anchor self-transitions toward the coiled shape, cinching engaged tissue of the valve annulus.
SYSTEMS AND METHODS FOR DEPLOYING A CARDIAC ANCHOR
A heart implant alignment and delivery device includes an elongate body having an opening that is disposed near a distal end of the elongate body. The opening is configured so that a heart implant is positionable within the opening with the heart implant exposed to a surrounding environment and so that the heart implant is substantially aligned with the distal end of the elongate body. The device also includes an implant reposition member, such as a cable, that is releasably coupleable with the heart implant and that is operationally coupled with the elongate body so that a first operation of the implant reposition member causes the heart implant to be retractably deployed from the opening of the elongate body. The first operation of the implant reposition member may be effected via a handle mechanism that is attached to a proximal end of the elongate body.
