Abstract: A deployment catheter for deploying a tubular endoluminal vascular prosthesis includes a proximal tubular section and a distal tubular section which are axially movable in opposite directions to deploy the prosthesis. A central core extends throughout the proximal tubular section and into the distal tubular section. In one embodiment, a reinforcing structure is carried by the central core, spanning the junction between the proximal tubular section and distal tubular section. In another embodiment, the proximal tubular section and/or distal tubular section are rotationally linked to the central-core.

Abstract: A subcutaneously formed in place orthopedic fixation device is provided, such as for fixation of the spine or other bone or bones. The device comprises an inflatable member, such as a tubular balloon. A heat source is provided in thermal communication with the interior of the balloon. The balloon is positioned at a treatment site while in a flexible, low crossing profile configuration. The balloon is thereafter inflated with a hardenable media, and heated to accelerate hardening of the media. Methods and delivery structures are also disclosed.

Abstract: A programmable resistive-capacitive filter circuit enabling on-chip digital control of the frequency response includes a switched resistive type voltage divider network where one of the resistors forms an element of an RC filter and wherein the voltage divider additionally provides a DC bias on an output terminal. One preferred embodiment of the invention is directed to a programmable bandpass filter including MOSFET type semiconductor devices which are utilized as switched resistive elements of the filter.

Abstract: An implantable inflatable orthopedic device is provided. The device comprises a flexible wall, defining an interior cavity, a reinforcing element exposed to the cavity, an inflation pathway in communication with the cavity, and a valve, for closing the pathway. A delivery catheter is also provided for removably carrying the orthopedic device to the treatment site.

Abstract: A current limiter circuit for limiting current in an electrical circuit element such as the magneto-resistive portion of a read head forming a portion of a hard disk drive and including: a first circuit connected to one end of the circuit element for applying a bias current of a desired value to the circuit element in response to the value to an input signal; a second circuit connected to the other end of the circuit element for setting the amplitude of the voltage signal generated across the circuit element in response to the bias current; and a third electrical circuit connected to both the first and second circuits for limiting the value of bias current to a predetermined level for an abnormal event such as a current surge, a short circuit, or any other type of undesired current operating condition.

Abstract: A subcutaneously assembled in place orthopedic construct is provided, such as for fixation of the spine. The construct includes a first bar and a second bar for attachment to the spine. A crossbar connects the first and second bar, to provide additional structural support. Each of the first bar, the second bar, and the crossbar may be inserted in a minimally invasive procedure, and constructed in place to form the orthopedic device. Each of the first bar, second bar, and crossbar may comprise an inflatable container, adapted for inflation with a hardenable media and cured in place. Methods and delivery structures are also disclosed.

Abstract: Disclosed is a deployment catheter for deploying a tubular endoluminal vascular prosthesis, useful in treating, for example, an abdominal aortic aneurysm. The deployment catheter includes a proximal tubular section and a distal tubular section which are axially movable in opposite directions to deploy a prosthesis. A central core extends throughout the proximal tubular section and into the distal tubular section. A reinforcing structure is carried by the central core, spanning the junction between the proximal tubular section and distal tubular section, to improve flexibility characteristics of the catheter. In one embodiment, the proximal tubular section and/or distal tubular section are rotationally linked to the central core.

Abstract: An endoluminal repair of abdominal aortic aneurysms at the aortic and iliac bifurcation. In particular, a deployment system and graft are disclosed for deploying the bifurcated graft within both iliac branches, as well as the aortic trunk, from a single vascular access. The disclosed deployment system includes a delivery catheter having a releasable restraint for the main body section of the graft and separate releasable restraints for each of the first and second branch sections of the graft.

Abstract: An automated interactive cytology system provides expedited handling of samples, minimizing false negatives, while not substantially increasing the number false positives. A computerized system identifies and displays the cells which are of greatest interest to the cytologist. The system then processes this information on all cells identified to classify the slide as normal, abnormal, or questionable based on a statistical analysis of cells meeting given criteria. Before displaying the results of the statistical analysis, a cytologist reviews the cells which the computer has determined to be most significant. It is only then after the cytologist has determined whether the cells are positive, negative, or questionable, that the determination is inputted into the automated system. The automated system then compares the cytologist's analysis with its own statistical analysis. Based on the two opinions, the cytologist determines how to advise a doctor regarding the sample.

Abstract: An array of at least three parallel rolls is provided. The rolls are constrained against each other to provide an elongated coating chamber through which passes a web entrained on at least one of the rolls. As it exits from the chamber, the coated web surface is wiped by another of the rolls, whose surface is entering the chamber at that point.
