Patent number: 8372115Abstract: A bone support and/or barrier device and having an implantable structure including an outer surface, an inner surface, a first bone contact portion, and a second bone contact portion. The structure is collapsible to an undeployed configuration capable of percutaneous insertion to the interior of a bone and expandable to a deployed configuration in the bone. In the deployed configuration, the first bone contact portion contacts a first portion of the bone, and the second bone contact portion contacts a second portion of the bone such that a load placed on the first portion of the bone is transferred through the implantable structure to the second portion of the bone. The implantable structure includes a barrier material adapted to restrict bone filler material inserted into the bone adjacent the inner surface of the structure from flowing to the outer surface of the structure. A method is also disclosed.Type: GrantFiled: September 13, 2011Date of Patent: February 12, 2013Assignee: Kyphon SARLInventors: Andrew Kohm, Janna Clark, Samuel Lee, Thomas A. Slater

Patent number: 8372082Abstract: A force-limiting clutch for a surgical instrument includes a drive element and a transmission element. An actuator is coupled to the drive element, and a drive shaft is coupled to the transmission element for providing an output force. If the force input from the actuator to the clutch reaches a predetermined threshold, the force-limiting clutch “slips” and does not transfer the actuator force to the drive shaft to prevent excessive force/pressure output. Normally, drive features on the drive element engage with transmission features on the transmission element to transfer forces from the actuator to the drive shaft. When a threshold force is reached, the drive features slip past the transmission features. This clutch “breakpoint” determines the maximum loading that the surgical instrument can provide at its output. In various embodiments, multiple transmission features can be arranged in a serial manner, such that the force-limiting clutch provides multiple breakpoints.Type: GrantFiled: July 30, 2009Date of Patent: February 12, 2013Assignee: Kyphon SARLInventors: Bryan A.
