Abstract: The invention encompasses devices and methods used to keep the objective lens of a viewing or illuminating device, specifically an endoscope, free from obstructive fluid and dirt; specifically a device having a hollow body designed to fit over an endoscope, a transparent lens cover film that is retained within the device and that is threaded in front of the objective lens of an endoscope, thereby maintaining a clear and unobstructed transparent window in front of the endoscope lens, and an endcap configured to engage opposing edges of the lens cover film in a sealing manner.

Abstract: Systems are provided for delivering a suture to close a surgical opening. An elongated deployment member may have at its distal end a retracted counterforce member. The counterforce member may be inserted into the surgical opening and deployed to resist being withdrawn from the opening. A compression member may be slid down the elongated member to compress the tissue to be sutured against the counterforce member. Suture passers loaded with suture ends may be passed through needle tubes within the elongated member to emerge from the elongated member and pierce the tissue to be sutured, then deposit the suture ends with a suture catcher. The suture passers may be withdrawn, leaving the suture ends. The suture catcher may be retracted, retaining the suture ends and the device—elongated member, retracted suture catcher, and retained suture end—may be withdrawn from the surgical opening. The suture may then be completed.

Abstract: A spinal dynamic stabilization device for maintaining an anatomical height between two adjacent vertebras is provided. Each vertebra includes a spinous process and two symmetric pedicles. The spinal dynamic stabilization device includes a supporting member, at least one anchoring member, and at least one connecting member. The supporting member is disposed between the spinous processes. The anchoring member is fixed in one of the vertebra via one of the pedicles. The connecting member connects the supporting member to the anchoring member, fixing a relative position between the supporting member and the anchoring member, further fixing a relative position between the vertebras.
