Abstract: In an embodiment, a network may represent a physical system. The network may have an element that represents an entity of the physical system. A value of a state associated with the network may be identified (e.g., generated) using various techniques. The state may be a low-level state associated with the network. The techniques may include, but are not limited to, for example, generating the value based on a scaffold defined for the network, generating the value based on a target value for the state, and/or generating the value based on applying an operation to various values of the state. The identified value may be associated with an identifier. The identifier may distinguish the value, for example, from other values of other states in the network and/or other values of states in other networks.

Abstract: In an embodiment, an element, that represents an entity in a system, is generated. The generated element may be incorporated in a network that represents the system. The generated element may include geometry information about a geometry of the entity. The geometry information may be used in one or more computations associated with a simulation or an analysis of the system. The element may have a frame port that exposes a frame. The frame may represent at least a position and an orientation in a two dimensional or three dimensional space with respect to another frame in the network. The other frame in the network may be a reference frame that may be defined by a “world” that the system resides in. The generated element may be incorporated into the network by connecting the frame port to the network.

Abstract: A device may include communication logic to receive a request to perform an activity on behalf of a client, where the activity is related to a primary application and a secondary application. The communication logic may send a response that allows the client to perform the activity when the client is authorized. The device may include evaluation logic to determine whether the client is related to the primary license and to determine whether a secondary license related to the secondary application is available. The evaluation logic may allocate the available secondary license to the client for use with the secondary application when the secondary license is available. The evaluation logic may authorize the client to perform the activity when the secondary license is allocated to the client.

Abstract: A self propelling catheter introducer system for exploring a body cavity is disclosed which includes a flexible tubular catheter, an everting tube and a steering section located near the distal end of the catheter that is introduced in a body cavity. The steering section is adapted for pointing the distal end in a desired direction using a plurality of rods adapted to be extended and retracted.

Abstract: A catheter introducer system for endoscopy is disclosed which includes a steering section and a propulsion section located near the end of the catheter that is introduced in a body cavity, and a non-collapsible sheath defining a working channel, disposed inside the catheter, extending substantially from the proximate to the distal end and maintaining a substantially circular cross-section even when bent along an axis. The propulsion section is designed to pull the rest of the catheter inside the body cavity, so there is no need to push the catheter along. The catheter can thus be made very flexible in bending, and a larger diameter catheter can be used without discomfort to the patient.

Abstract: The present invention relates to an endoscopic visioning system and related method for both forward and backward viewing of a body lumen. According to an embodiment, the system includes an endoscope, a vision head including a light source and a vision chip on both a proximal and a distal side of the vision head, and an extension arm for moving the vision head away from and back toward the endoscope. Alternatively, the light source and vision chip may be contained in a distal end of the endoscope. In -such an alternative embodiment, the vision head is a parabolic mirror mounted on the extension arm for reflecting images, for example, from behind the distal end of the endoscope to the vision chip in the distal end of the endoscope to permit, for example, a retrograde view of the surgical site entrance.

Abstract: A full thickness resection device comprises a control handle including an actuator wherein, when the device is in an operative position within a body lumen of a patient, the control handle remains outside the patient's body and a working head assembly coupled to a control handle by a flexible sheath, wherein, when the device is in the operative position; the working head assembly is located within a body lumen of the patient adjacent to a portion of tissue to be treated, the working head assembly including a tissue stapling mechanism including first and second tissue stapling members moveable relative to one another in combination with a first cable extending from the actuator through the flexible sheath to the first tissue stapling member so that, when the actuator is operated to draw the first cable proximally from the sheath, the first tissue stapling member is moved in a first direction relative to the second tissue stapling member.

Abstract: The present invention generally relates to surgical clips. A surgical clip comprises a first piece comprising a first base and a first projection extending from the first base, a second piece comprising a second base, a second projection extending from the second base wherein the second projection further comprises a top surface, at least one side surface and a bottom surface, the surfaces defining a reservoir therein, and the first and the second piece are detachably connectable. In a preferred embodiment, the reservoir is self-releasing to deliver therapeutic materials when the first piece and second piece are connected.
