A minimal incision maximal access system allows for maximum desirable exposure along with maximum access to the operative field utilizing a minimum incision as small as the METRx and Endius systems. Instead of multiple insertions of dilating tubes the design is is a streamlined single entry device to avoid repetitive skin surface entry. The system offers the capability to expand to optimum exposure size for the surgery utilizing hinged bi-hemispherical or oval working tubes applied over an introducer obturator which is controllably dilated to slowly separate muscle tissue. Deeper end working and visualization areas with maximum proximal access and work dimensions are provided to makes the operative procedure safer in application and shorten the surgeons's learning curve because it most closely approximates the ability to use open microdiskectomy techniques.

A trans-septal guide catheter for providing access through the septum separating a first heart chamber from a second heart chamber that includes an elongated guide catheter body extending between guide catheter proximal and distal ends. A distal segment of the guide catheter is adapted to be inserted through the septum to locate the distal segment of the guide catheter within one of the first heart chamber and the second heart chamber. The catheter body encloses a guide catheter lumen adapted to provide access into the one of the first heart chamber and the second heart chamber through a guide catheter lumen proximal end opening and a guide catheter lumen distal end opening. A retention mechanism engages the septum and maintains the distal segment of the guide catheter extending into the one of the first heart chamber and the second heart chamber.

A subsea hydrocarbon production system comprises a tubing hanger which is positioned at an upper end of a well bore, a tubing string which extends from the tubing hanger into the well bore and is fluidly connected to the tubing hanger production bore, and a christmas tree which is positioned above the tubing hanger. The christmas tree comprises a production bore which is fluidly connected to the tubing hanger production bore, a production outlet which is connected to the production bore, a first barrier element which is positioned in the production outlet, and a first closure device which is positioned in the production bore above the production outlet. In this manner access from above the christmas tree through the production bore does not require passage through a barrier element.

A method and structure for furnishing pressure-evenized, dynamic-reaction anatomical support. The method includes (a) supporting the anatomy with a 100% open cell viscoelastic foam, and (b) within the foam, reacting to both static and dynamic, anatomically-produced foam indentations to expand and contract cell-openness size, whereby deeper / sharper indentations result in greater-size cell-openness. Such reacting includes laterally stretching and flowing regions of the foam adjacent such an indentation The overlay structure features (1) a dynamic-response core expanse formed of a 100% open-cell, compressible and flowable, polyurethane, viscoelastic foam possessing a compressed, relaxed-state volume, and (2) an elastomeric, moisture- and gas-flow-managing coating, load-transmissively, bonded to the entirety of the core expanse's outside surface to function as a dynamically-responsive unit with the expanse. The coating possesses a relaxed-state, prestressed tension condition which is responsible for the expanse's compressed condition.

A layer two forwarding protocol (L2F) provides virtual direct dial-up service into private networks through public internet service providers. An authorized remote client appears as a direct dial-up client to the home gateway, even through the client is accessing the home gateway remotely through the ISP. The new forwarding protocol allows the remote client to conduct point-to-point link protocols, such as point-to-point protocol (PPP) and serial line interface protocol (SLIP) directly with the local network home gateway. The network access server changes from a routing mode where a communication protocol is conducted with the client to a switching mode where the POP simply sends data from one port to a tunnel. The tunnel then transmits the data to another port, regardless of the header information on transmitted data packets. The remote client can then be managed through databases controlled by the local network and gain access to resources not typically accessible through the internet. The layer two forwarding protocol conducts an independent authorization session to prevent unauthorized access to the private network and provides point-to-point protocol transport over the internet independently of internet transport protocols.

A lightweight one man screed apparatus to automatically strike off and level uncured concrete flatwork, includes a tri-pod framework beneath which a cutting / leveling member operates. The apparatus is controlled by two grade setting devices, adjustably mounted to the screed tool, which may be adjusted relative to a laser plane generating system. Physical control of the screed member may be provided by at least one screed tool pivotal arm assembly moved for and aft by a carriage operated under the tri-pod framework within a fore and aft footprint. The screed tool is adjusted to grade by being raised or lowered by at least one linear actuators responding to an electronic controller. When moving the framework and screed assembly into freshly poured concrete, an operator is assisted by retractable wheels. The wheels are rotationally stowable or used deployed as part of the tripod / transport system facilitating mobility.

A breathing circuit for sequential gas delivery of a first gas set (FGS) and a second gas set (SGS) employs an arrangement of conduits and active or passive valves to prevent mixing of the FGS and SGS including a valve triggered by depletion of FGS that makes the SGS available for inspiration after the FGS is depleted.

Methods and apparatus for providing percutaneous access to the presacral space in a minimally invasive, low trauma, manner. A number of related methods and surgical tool sets form a percutaneous pathway from an incision through the patient's skin adjacent to the coccyx and inserting an elongated guide assembly through the incision to locate the guide assembly against the anterior surface of the sacrum to access a presacral target point. The provision of the percutaneous pathway described herein allows for the introduction of therapeutic devices or media, diagnostic instruments, and / or drug delivery to the presacral space.
