International Classification:

A61B 17/56

US Classification:

606 80, 606 61, 606170

Abstract:

A flexible drill and method of drilling a material are disclosed. According to one embodiment, a flexible drill includes a lower sub-assembly connected to an upper sub-assembly, where the lower sub-assembly comprises a retainer tube and the upper sub-assembly comprises a guiding tube; a drilling tip, and capable of orienting the drilling tip at a predetermined position after accessing a material to he drilled through a substantially straight passage having a lone axis. The predetermined position is at least 10 off of the lone axis of the substantially straight passage. According to one embodiment, a method of drilling a material includes the steps of (a) providing a flexible drill; (b) advancing the drill through a substantially straight passage until the drilling tip accesses the material to be drilled, thereby orienting the drilling tip at the predetermined position; and (c) actuating the drill.

International Classification:

A61B 17/88

US Classification:

606279

Abstract:

The present invention relates generally to systems and methods for aligning and implanting orthopedic fixation or stabilization implants within the body. In one embodiment, the system includes at least two bone anchors, at least one of which is provided with an angularly adjustable connector. In one aspect, the system also includes at least one linkage rod, for linking two or more bone anchors through their respective adjustable connectors. The bone anchors and the linkage rod may be locked into place to form a spinal fusion or fixation prosthesis. An alignment tool is provided, for guiding a guidewire through one or more connectors.

US Classification:

623002360, 606151000, 600012000

Abstract:

Tissue shaping methods and devices are provided for reinforcing and/or remodeling heart valves. In certain embodiments, magnetic tissue shaping devices are implanted in tissue adjacent heart valve leaflets. The devices are mutually attractive or repulsive so as to remodel the heart tissue and improve heart valve function. In certain other embodiments, one or more tissue shaping devices including shape memory material are implanted in a patient's body within or on tissue adjacent a heart valve leaflet. The shape memory material can be activated within the patient in a less invasive or non-invasive manner, such as by applying energy percutaneously or external to the patient's body. The shape memory tissue shaping devices are implanted in a first configuration and then activated to remember a second configuration that displaces tissue so as to remodel the heart valve geometry and improve heart valve function. In certain other embodiments, a brace is crimped to the base of a heart valve leaflet to support the leaflet and improve valve closure.
