| 20080208175 | IRIS VALVE WITH CONTROL RING - A laparoscopic surgical access device comprises a first frame and a second frame having relative axial positions. A flexible and resilient iris valve is connected to the first and second frames and has a closed position and an opened position based on the relative angular position of the first and second frames. A lock is connected to the first and second frames, the lock being selectively operative to prevent relative rotational movement in a first rotational direction. One embodiment uses a ratchet and pawl mechanism operable with a control ring. Another embodiment uses a ratchet and pawl mechanism operable with a button. Yet another embodiment uses a wedge track and ball mechanism. | 08-28-2008 |

| 20090137877 | TISSUE RETRACTORS - Methods and devices are provided for performing surgical procedures using tissue retractors. In general, a surgical retractor device is provided that includes a flexible fabric tissue retractor configured to support tissue. At least one grasping element can be coupled to a perimeter of the flexible fabric, and the grasping elements can be manipulated to couple the flexible fabric to a surgical port, e.g., a trocar, inserted through a body wall and extending into a body cavity. The grasping element can also be configured to move the flexible fabric and thereby move the tissue. | 05-28-2009 |
| 20090137984 | TISSUE RETRACTORS - Methods and devices are provided for performing surgical procedures using tissue retractors. In general, the methods and devices allow a surgeon to use a retractor to capture a large or small amount of tissue in the retractor and to move the retractor to relocate tissue to one or more convenient locations during a surgical procedure. The retractor can be configured from a pliable state to a substantially rigid state to hold the retractor and the tissue in a substantially fixed position during the procedure. | 05-28-2009 |
| 20090270681 | SCRAPING FLUID REMOVAL IN A SURGICAL ACCESS DEVICE - The present invention generally provides methods and devices for removing fluid from a surgical instrument. Surgical access devices and seal systems are generally provided having one or more valves or seal assemblies to create a closed system between the outside environment and the environment in which the surgical access device is being inserted. In one embodiment, a seal assembly is provided and can include a seal having an opening configured to receive a surgical instrument therethrough and a fluid remover in the form of an absorbent element, a scraper element, a wicking element, or any combination thereof can be associated with the seal and configured to remove fluid from the opening and/or a surgical instrument. | 10-29-2009 |
| 20090270685 | ABSORBING FLUIDS IN A SURGICAL ACCESS DEVICE - The present invention generally provides methods and devices for removing fluid from a surgical instrument. Surgical access devices and seal systems are generally provided having one or more valves or seal assemblies to create a closed system between the outside environment and the environment in which the surgical access device is being inserted. In one embodiment, a seal assembly is provided and can include a seal having an opening configured to receive a surgical instrument therethrough and a fluid remover in the form of an absorbent element, a scraper element, a wicking element, or any combination thereof can be associated with the seal and configured to remove fluid from the opening and/or a surgical instrument. | 10-29-2009 |
| 20090270813 | WICKING FLUID MANAGEMENT IN A SURGICAL ACCESS DEVICE - The present invention generally provides methods and devices for removing fluid from a surgical instrument. Surgical access devices and seal systems are generally provided having one or more valves or seal assemblies to create a closed system between the outside environment and the environment in which the surgical access device is being inserted.
