A bendable polymer tissue fixation device suitable to be implanted into a living body, comprising a highly porous body, the porous body comprising a polymer, the porous body comprising a plurality of pores, the porous body being capable of being smoothly bent, wherein the bending collapses a portion of the pores to form a radius curve, the polymer fixation device being rigid enough to protect a tissue from shifting. In a preferred embodiment the polymer fixation device may be capable of being gradually resorbed by said living body. In one embodiment, the polymer fixation device comprises a plurality of layers distinguishable by various characteristics, such as structural or chemical properties. In another embodiment, the polymer fixation device may comprise additional materials; the additional materials serving to reinforce or otherwise alter the structure or physical characteristics of the device, or alternatively as a method of delivering therapy or other agents to the system of a living being.

Methods and devices described herein facilitate improved access of locations within the body by providing a variety of dissection modes on a single access device.

System, including methods, apparatus, and kits, for retrograde placement of fasteners into bone.

A high strength porous biphasic polymeric reinforcement material manufactured by a compression and / or sintering process is disclosed. The material results in a network of interconnected collapsed pores, which forces thin overlapping walls and passages to be created. The network provides permeable access for fluid migration throughout the material. The strength and / or permeability are advantageous for medical devices and implants.

A medical manipulator system includes a manipulator, an operating unit for entering operation commands, motors for actuating a working unit, and a controller for energizing the motors based on operation commands supplied from the operating unit. When an activation resetting switch and a resetting switch are operated according to a predetermined procedure, the controller performs a resetting process to return the motors to an origin. The controller is capable of controlling three manipulators. The activation resetting switch is shared by the three manipulators, and there are three resetting switches corresponding to the three manipulators.

An endoscopic instrument comprises a shaft, comprising a proximal end and a distal end. A grip comprising a handle is arranged at said proximal end of said shaft and a tool having at least an open and a closed position is arranged at said distal end of said shaft. Said shaft comprises at least two sections, a first section and a second section, which can be articulated with respect to said first section. Said second section comprises said tool. Said instrument further comprises an actuating element, by means of which said handle is in operative connection with said second section and with which an articulation of said second section can be initiated. Said first section or said actuating element and said tool are connected by a control element, by means of which said tool can be moved back and forth between said closed position and said open position in the course of an articulation of said second section, such that both the articulation of said second section and an opening / closing of said tool can be accomplished by the movement of said actuating element.

The invention generally concerns a spine stabilization system having one or more flexible elements having an opening or slit. The flexible element may be integrally formed in a rod having ends capable of receiving fasteners. The flexible element may limit rotation, flexion-extension, or lateral bending of the spine. The slit or opening may form helical pattern on the rod, and more than one slit or opening may be provided. The flexible element may be conformable to the natural spinal movement.
