Abstract: Methods and systems for closing an opening or defect in tissue, closing a lumen or tubular structure, cinching or remodeling a cavity or repairing a valve preferably utilizing a purse string or elastic device. The preferred devices and methods are directed toward catheter-based percutaneous, transvascular techniques used to facilitate placement of the devices within lumens, such as blood vessels, or on or within the heart to perform structural defect repair, such as valvular or ventricular remodeling. In some methods, the catheter is positioned within the right ventricle, wherein the myocardial wall or left ventricle may be accessed through the septal wall to position a device configured to permit reshaping of the ventricle. The device may include a line or a plurality of anchors interconnected by a line. In one arrangement, the line is a coiled member.

Abstract: Method and apparatus are disclosed for distracting tissue and particularly spinal tissue. The device and method may include insertion of at least one elongated member and an augmenting member to form a structure between the tissues to be distraction, such that a dimensional aspect of the structure is augmented upon movement of the augmenting structure.

Abstract: Methods and apparatus are disclosed for distracting tissue. The devices and methods may include insertion of first and second elongated members into the space between two tissue layers, with an augmenting elongated member inserted therebetween to form a distraction device between the tissues to be distracted. The distraction device defines a generally annular configuration, with a locking member secured to one of the elongated members at a plurality of locations to maintain the distraction device in the generally annular configuration. The augmenting elongated member may be shorter than the first and second elongated members such that a window is defined between the proximal and distal ends of the augmenting elongated member when the distraction device and the first and second elongated members are in the generally annular configuration. Bone graft material or bone filler may be introduced into the interior of the distraction device through the window.

Abstract: The present disclosure relates to devices for injecting material into a body. The devices include a housing having a deployment cannula extending therefrom. The device also includes a rotary drive member wherein rotational movement of the drive member relative to the housing results in linear movement of an elongated injection member within a lumen of and out of a distal end opening of the deployment cannula. The elongated injection member includes a proximal end portion that may have a Tuohy-Huber tip and/or varying radii therealong.

Abstract: Spinal tissue distraction devices that include a member which has a pre-deployed configuration for insertion between tissue layers and a deployed configuration in which the member, by change of configuration, forms a support structure for separating and supporting layers of spinal tissue

Abstract: Devices are provided for measuring and/or adjusting the distance between two opposing surfaces of a work space, such as two vertebral bodies separated by a disc space. A sizing device may include at least one distraction member, an actuator, and an actuator controller. The actuator controller is movable to move the actuator, with movement of the actuator changing the height dimension of the distraction member. The amount of movement of the actuator controller is generally linearly related to the change of the height dimension of the distraction member throughout the entire range of motion of the actuator controller. The amount of expansion force applied by the distraction member is also generally linearly related to the amount of movement of the actuator controller.
