摘要:
This specification describes spinal stabilization devices that may be introduced into the spine via surgical procedures. In particular, this specification describes an inter-spinous process spacer having a core chosen, in one variation, to provide a kyphotic or lordotic angle to the device. The specification also describes systems including the described devices and methods of introducing the devices and systems into the spine to provide effective stabilization.

Disclosed herein is a system for releasing a ligament. In one embodiment, the system includes a proximal handle, a tubular body, and a flexible body. The tubular body includes a proximal end and a distal end. The handle is coupled to the proximal end. The flexible body extends through the tubular body and includes a tissue cutting portion. The flexible body or tubular body is longitudinally displaceable to move the tissue cutting portion between a non-deployed state and a deployed state.
摘要:
An image forming apparatus including an image bearing member; a developing device for developing with toner an electrostatic latent image formed on the image bearing member; a humidity sensor for providing information on ambient humidity of said image forming apparatus; and a controller for controlling a parameter on a density of an image to be formed on a recording material on the basis of pieces of the information provided by the humidity sensor at different times. The controller is capable of controlling the parameter so that, when a first image forming job is ended at an ending time and then a second image forming job is executed after a lapse of a predetermined time from the ending time and in a period in which a detection result of the humidity sensor changes and then is constant, a difference between a first set value which is the parameter set during formation of a final image in a first image forming job and a second set value which is the parameter set during image formation on a first sheet in the second image forming job after the lapse of the predetermined time from the ending time, increases with an increase of proportion of a time in which the developing device is driven during the lapse of the predetermined time.
