  • Publication number: 20100274223
    Abstract: A subcutaneous needle conduit attaches directly to a blood vessel or other biological boundary structure. The subcutaneous needle conduit is tapered such that a proximal end is wider than a distal end. A body of the subcutaneous needle conduit guides the tip of a needle or other canula from the proximal end to the distal end. The subcutaneous needle conduit may be funnel-shaped. An elongated funnel shape may be used to selectively provide access to a plurality of desired access sites along an axis of a blood vessel. Other shapes, such as sluice-shaped, may also be used. The subcutaneous needle conduit may be located beneath the skin surface using, for example, tactile sensation, magnetism, metal detection, detection of a signal emitted from a minute transponder, detection of light emission, or through other detection methods.

  • Publication number: 20100256619
    Abstract: An embodiment of the present invention is directed to methods and devices for treating diseases and conditions that change the special relationship between vertebral bodies and intervertebral disks. A method for performing a transpedicular discectomy procedure may include creating a transpedicular channel to a first vertebral body through a first pedicle of a first vertebra; inserting a flexible drill through the transpedicular channel causing the flexible drill to make an approximately 90 degree angle, the flexible drill creating a channel through the first vertebral body into an intervertebral disk; and removing a portion of the intervertebral disk with a laser device.

  • Patent number: 7722668
    Abstract: 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 shape memory material, and an energy absorption enhancement material configured to absorb energy in response to an activation energy. The energy absorption enhancement material is in thermal communication with said shape memory material.

  • Publication number: 20100081868
    Abstract: 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.

  • Publication number: 20090312806
    Abstract: An inflatable corpectomy device comprises a balloon, which defines a cavity for receiving a hardenable media. The device can be inserted in an un-inflated form into a space formerly occupied by a diseased or damaged vertebrae bone. When inflated with a hardenable material, the device expands and fills the space. Various bone anchors or plates can be used in combination with the inflatable device to bridge the space and stabilize the spine while the device hardens.

  • Publication number: 20090248148
    Abstract: 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.

  • Publication number: 20090088838
    Abstract: 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.
