1222 results about "Access port" patented technology

Access port. An access port is a computer port that transports traffic to and from only the specified Virtual Local Area Network it is allotted to. Usually, an access port will only have a single VLAN set up on the interface and it carries traffic for just a single VLAN. Submitted by MC Harmonious on January 26, 2015.

Vascular access port with elongated septum

An elongated access port has a needle-impenetrable housing enclosing a fluid reservoir. The housing includes a base having a floor with an upstanding encircling sidewall and a cap having a top wall with a depending encircling skirt. The skirt of the cap receives the sidewall of the base. An access aperture extends through the top wall of the cap to communicate with the fluid reservoir. The access aperture is encircled by a continuous rim having an elongated shape in the plane of the access aperture. The rim of the access aperture may be elliptical, oval, polygonal, or parabolic-ended. An elastomeric, needle-penetrable, generally planar septum is disposed in the access aperture with the periphery of the septum in sealing engagement with the rim of the access aperture. Prior to installation, the septum has a periphery with a cross section in the plane of the septum that is geometrically proportional to and larger than the shape of the access aperture. Installation causes the periphery of the septum to be displaced inwardly by the rim of the access aperture in a direction parallel to the plane of the septum. In view of the relative shapes of the rim of the access aperture and the periphery of the septum, this produces substantially uniform hydrostatic pressure in regions of the installed septum that are subjected in use of the access port to needle penetrations. Opposite faces of the periphery of the septum are urged toward each other between the cap of the housing and the top of the sidewall of the base of the housing.

Wound retractor device

A wound protector and retractor device 1 comprises a sleeve 2, a distal member provided by a distal ring 3 of resilient material and a proximal member provided by a proximal ring 4. The sleeve 2 is led around the ring 3 and is free to move axially relative to the distal ring 3 somewhat in the manner of a pulley. The proximal ring 4 is fixed to the sleeve 2, in this case at the proximal inner end thereof. The sleeve 2 terminates in a handle or gripping portion which is reinforced by a gripping ring 15. The sleeve extends from the proximal ring 4 and the distal ring 3 is contained between inner and outer layers 2a, 2b of the sleeve 2. The resilient distal ring 3 is scrunched up and inserted through the incision 6. The sleeve 2 is then pulled upwardly. On pulling of the sleeve 2 upwardly the outer layer 2b is pulled up while the inner layer 2a is drawn around the proximal ring 3. This results in shortening the axial extent between the proximal ring 4 and the distal ring 3, tensioning the sleeve and applying a retraction force to the margins of the incision 6. As the incision is being retracted the margins are also protected by the sleeve. On retraction, an access port is provided, for example for a surgeon to insert his hand and/or an instrument to perform a procedure. The device may be used as a retractor in open surgery or as a base for a valve/seal to allow it to be used in hand assisted laparoscopic surgery or for instrument access or hand access generally.

Devices and methods for port-access multivessel coronary artery bypass surgery

Surgical methods and instruments are disclosed for performing port-access or closed-chest coronary artery bypass (CABG) surgery in multivessel coronary artery disease. In contrast to standard open-chest CABG surgery, which requires a median sternotomy or other gross thoracotomy to expose the patient's heart, post-access CABG surgery is performed through small incisions or access ports made through the intercostal spaces between the patient's ribs, resulting in greatly reduced pain and morbidity to the patient. In situ arterial bypass grafts, such as the internal mammary arteries and/or the right gastroepiploic artery, are prepared for grafting by thoracoscopic or laparoscopic takedown techniques. Free grafts, such as a saphenous vein graft or a free arterial graft, can be used to augment the in situ arterial grafts. The graft vessels are anastomosed to the coronary arteries under direct visualization through a cardioscopic microscope inserted through an intercostal access port. Retraction instruments are provided to manipulate the heart within the closed chest of the patient to expose each of the coronary arteries for visualization and anastomosis. Disclosed are a tunneler and an articulated tunneling grasper for rerouting the graft vessels, and a finger-like retractor, a suction cup retractor, a snare retractor and a loop retractor for manipulating the heart. Also disclosed is a port-access topical cooling device for improving myocardial protection during the port-access CABG procedure. An alternate surgical approach using an anterior mediastinotomy is also described.

Optical network subscriber access architecture

A technique for providing an optical signal to a destination. In one embodiment, the technique is realized through the use of an environmentally hardened, modular switch and a fiber distribution methodology. The modular switch may include fiber access ports, power access ports, dual power supply modules, dual switch fabric modules, dual optical trunking modules, and multiple subscriber service modules that house subscriber service ports and serve a total of up to 96 end points. The dual optical trunking modules may act as an interface between an optical network and the dual switch fabrics, and provide redundancy and variable optical transmission distance between the modular switch and the optical network to which the modular switch is connected. The dual switch fabrics are used for switching and aggregating signals and providing redundancy. Each subscriber service module acts as an interface between one or more subscriber end points and the dual switch fabrics of the modular switch. The subscriber service modules may be coupled to one or both of the dual switch fabrics and a total of up to 96 subscriber end points. Subscriber end point connectivity may be achieved via subscriber service ports (housed within a subscriber service module), one or more of the fiber access ports, external fiber optic splice cabinet, fiber optic trunk cable, and one or more fiber breakout points (housed by pedestals). The subscriber end points may consist of one or more optical or electrical subscriber connection types.

Method for locating an implanted fluid access port

An implanted fluid access port locator system for adjustable gastric bands. The system may include an access port having an RFID tag with its antenna adjacent to the receiving portion of the port. An external locator with radio frequency transmitter/receiver circuitry sends read or interrogation signals to the RFID tag and may send write signals to the tag to write treatment data to memory of the RFID tag. The locator may include an antenna array with four patch antenna arranged in pairs to model two monopulse radar antenna systems. The locator also includes processor(s) and logic modules/circuitry for processing the tag response signals received by the antenna array to determine location information for the RFID tag and associated port, i.e., to identify the center of the port relative to the antennae array or array face such as with strength and direction information relative to the array face. A method of locating implanted fluid access port includes providing radio frequency transmitter/receiver circuitry on the access port and manipulating a handheld locator outside the body to pinpoint the position and orientation of the access port. A mark may be made with a handheld locator to direct insertion of a needle for adding or removing fluid from an implanted system through the access port.
