摘要:
Expandable support devices for tissue repair are disclosed. The devices can be used to repair hard or soft tissue, such as bone or vertebral discs. A method of repairing tissue is also disclosed. Surgical devices and methods for adjusting (e.g., removing, repositioning, resizing) deployed orthopedic expandable support devices are also disclosed. The expandable support devices can be engaged and surgically implanted by an engagement device and affixed to bone to provide stability and support for the devices. The expandable support devices are attachable to spinal fixation devices such as screws or plates, and may be used to support such devices when placed in weakened or damaged areas of bone.
摘要:
A tool for working in a cavity to which access is limited is disclosed. The tool has an elongated sheath with a bore and an open end that is positionable within the cavity. A filamentary element is slidably positioned within the bore of the sheath. A portion of the filamentary element is extendible outwardly from the sheath through the open end and into the cavity. The filamentary element may be biased into a curved or helical shape, and may be a loop or may have an awl, a cutting blade, a scoop, hook, balloon or other piece attached to its end.
摘要:
The present invention provides an aortic valvuloplasty catheter which, in one preferred embodiment, has a tapered distal balloon segment that anchors within the left ventricle outflow track of the patient's heart and a rounded proximal segment which conforms to the aortic sinuses forcing the valve leaflets open. In addition, this embodiment of the valvuloplasty catheter includes a fiber-based balloon membrane, a distal pigtail end hole catheter tip, and a catheter sheath.
