A surgical instrument particularly suited to endoscopic use articulates an end effector by including a laterally sliding member in a proximal portion of a shaft that pivots the end effector to a selected side. Differentially opposing actuating forces (e.g., hydraulic, fluidic, mechanical) act against the laterally sliding member without binding by incorporating guidance mechanisms between the laterally sliding member and a frame of the shaft.

A surgical stapling and severing instrument particularly suited to endoscopic use includes a proximal portion that is manipulated external to a patient to position an attached elongate shaft and end effector to a desired surgical site inside of the patient. An articulation joint pivotally attaches the end effector to the elongate shaft to give further clinical flexibility in reaching tissue at a desired angle. A closure tube assembly includes a single pivoting portion that overrides the articulation joint in order to distally translate to the end effector to close, yet pass over an articulated shaft by having a multiple pivot frame ground encompassed therein to accommodate the longitudinal change in closure sleeve pivot. Thereby, additional clinical flexibility in positioning the end effector is achieved without losing the ability for separate closure and firing motions transferred by the shaft.

A surgical instrument particularly suited to endoscopic use articulates an end effector by including a fluid transfer articulation mechanism that is proximally controlled. A fluid control, which is attached to a proximal portion, transfers fluid through the elongate shaft through a first fluid passage to a first fluid actuator that responds by articulating an articulation joint. Two opposing fluid actuators may respond to differential fluid transfer to effect articulation. Thereby, design flexibility is achieved by avoiding the design constraints of transferring a mechanical motion through the tight confines of the elongate shaft sufficient to effect articulation.

A circuit element is disposed on an organic substrate and is connected to a wiring pattern provided on the organic substrate. Internal connection electrodes are formed on a support of a conductive material through electrofomiing such that the internal connection electrodes are integrally connected to the support. First ends of the internal connection electrodes integrally connected by the support are connected to the wiring pattern. After the circuit element is resin-sealed, the support is removed so as to separate the internal connection electrodes from one another. Second ends of the internal connection electrodes are used as external connection electrodes on the front face, and external connection electrodes on the back face are connected to the wiring pattern.

The invention is directed to compositions and methods for preparing electrospun matrices comprising at least one natural biological material component and at least one synthetic polymer material. The natural component makes the matrices highly biocompatible while the molecular weight polymer component can impart additional strength mechanical strength to the scaffold and/or improve ease of manufacture by increasing viscosity and spinning characteristics of the solution during electrospining.

A head-up display system includes a display device for generating and displaying information to an eye of an observer; a tilted power combiner for superimposing the information displayed by the display device onto the forward view of the outside by the eye of the observer; and a relay optic assembly between the display device and the tilted power combiner for forming an intermediate image of the displayed information forwardly of the combiner that reflects the image towards the eye of the observer within an eye motion box to produce a large field of view for the observer. The relay optic assembly is void of holographic elements and includes a spherical mirror generating aberrations in the intermediate image tending to compensate for aberrations produced by the tilted power combiner.

An implantable lead for transmitting electrical signals between a proximal end and a distal end comprises an elongated lead body defining a longitudinally-extending lumen, and a plurality of individual electrical conductors contained in the lumen of the lead body and extending between the proximal and distal ends, the plurality of individual conductors sharing a common insulating coating. Each of the plurality of individual electrical conductors preferably comprises a braided, multifilar cable conductor. In one embodiment, the common insulating coating electrically isolates the plurality of conductors from each other, and may include a bridging portion extending between individual conductors.

The plurality of electrical conductors and the common insulating coating comprise a conductor assembly that may have a helical configuration defining a longitudinally-extending passageway for receiving a stylet, guide wire, or the like, for placement of the distal end of the lead. Alternatively, the conductor assembly may have a tubular configuration, the plurality of individual conductors being embedded therein in spaced-apart, parallel relationship or along a generally helical path along the length of the lead body for greater lead flexibility.

A catheter includes a flexible tubing having a proximal end and a distal end. The catheter also includes an electrode assembly attached to the distal end of the flexible tubing and including a first magnet therein. The electrode assembly including an electrically conductive tip electrode and an electrically nonconductive coupler which is connected between the tip electrode and the distal end of the flexible tubing. The electrically conductive tip electrode comprises a hollow elongated tip electrode including a sidewall provided with one or more elongated gaps extending through the sidewall. The one or more elongated gaps providing flexibility in the sidewall for bending movement of the tip electrode relative to a longitudinal axis of the catheter body. The first magnet is responsive to an external magnetic field to selectively position and guide the electrode assembly within a body of a patient.

A method is described for making an elasticized absorbent article having a waist opening and a pair of leg openings. First, multiple distributions of elastics are applied on a moving material sheet to form a moving web of an elastic composite. Then, each of a core section and a second material sheet is periodically applied onto the moving web to define a finished web of discrete elastic composite bodies. In subsequent steps, discrete absorbent pants articles are shaped from the finished web.
