  • Stent delivery system for detecting wall apposition of the stent during deployment
    Patent number: 9237961
    Abstract: A stent delivery and apposition detecting system includes at least one electrode pair of dissimilar metals mounted on a balloon of a balloon catheter. The electrode pair forms part of an electrochemical cell, and voltage and current generated from the electrochemical cell enables the system to detect when a stent mounted on the balloon achieves proper wall apposition. As the balloon is exposed to different environments, i.e., blood or tissue having different resistances, the electric potential of the electrochemical cell changes and an alert is generated by a feedback circuit to notify a user that the electrodes are in contact with tissue of the vessel wall. In one embodiment, the feedback circuit may be powered by the electrochemical cell. Multiple sets of electrode pairs may be mounted along the circumference and length of the balloon to detect differential contact between the deployed stent and the vessel wall.

  • CHAIN WEAR MONITORING DEVICE
    Publication number: 20160010977
    Abstract: A conveyor or drive chain wear monitor includes two sensors spaced apart from one another a predetermined distance which is less than the distance between the adjacent measuring points on a chain. Two timers are provided, one of which is a chain speed timer and the other of which is the chain wear timer. The two timers are both controlled by the spaced sensors. The upstream sensor, as determined by the direction of travel of the chain, turns the speed timer on and the wear timer off. The downstream sensor turns the speed timer off and the wear sensor on. Thus when a measuring point passes the upstream sensor, the speed timer is turned on, and is not turned off again until the same measuring point passes the downstream timer.

  • Transaction log management
    Patent number: 9223823
    Abstract: Managing a log-full condition of a transaction log in a transaction processing system, where the transaction log has a plurality of log records each associated with a particular transaction. When a log-full condition is detected, the active transaction having the oldest log entry of all active transactions is identified and logging for all transactions except for the identified transaction is temporarily suspended. A dynamic transaction backout of the identified transaction is initiated, with the writing of a backout record for the identified transaction to the log being delayed. Confirmation that the backout has completed is awaited before trimming the log. Then the delayed backout record for the identified transaction is written to the log, and normal logging is resumed.

  • Apparatus and methods for filling a drug eluting medical device via capillary action
    Patent number: 9204982
    Abstract: Methods and apparatus are disclosed for filling a therapeutic substance or drug within a hollow wire that forms a stent. The stent is placed within a chamber housing a fluid drug formulation. During filling, the chamber is maintained at or near the vapor-liquid equilibrium of the solvent of the fluid drug formulation. To fill the stent, a portion of the stent is placed into contact with the fluid drug formulation until a lumenal space defined by the hollow wire is filled with the fluid drug formulation via capillary action. After filling is complete, the stent is retracted such that the stent is no longer in contact with the fluid drug formulation. The solvent vapor pressure within the chamber is reduced to evaporate a solvent of the fluid drug formulation. A wicking means may control transfer of the fluid drug formulation into the stent.

  • Network Threat Detection and Mitigation Using a Domain Name Service and Network Transaction Data
    Publication number: 20150350229
    Abstract: In an embodiment, a method detects an abuse to a network environment. In the method, real-time name service transaction data to resolve a domain name to a network address is collected from the network environment. Historical name service information for the domain name is retrieved. Transaction information describing data sent between the network environment and the network address is collected. The collected transaction information and the historical name service information is analyzed against at least one rule. When the collected transaction information and the historical name service information are determined to match at least one rule, the network address is determined to be is associated with a potential abuser of the network environment.

  • APPLICATION AND NETWORK ABUSE DETECTION WITH ADAPTIVE MITIGATION UTILIZING MULTI-MODAL INTELLIGENCE DATA
    Publication number: 20150350240
    Abstract: In an embodiment, a computer-implemented method detects a network or application abuse to a service provider environment. In the method, data is collected describing incoming requests from plurality of different external source addresses to the service provider environment. The collected data is used to compare the incoming requests against a heuristic. When the incoming requests are determined to match the heuristic, the requests, having the plurality of different external source addresses, are from a common abuse entity. Finally, the collected data is evaluated to determine that the common abuse entity is a potential network abuser of the service provider environment.

  • CONTINUOUS TRANSDERMAL MONITORING SYSTEM AND METHOD
    Publication number: 20150305683
    Abstract: Various embodiments of methods and systems for continuous transdermal monitoring (“CTM”) are disclosed. One exemplary method for CTM begins by monitoring an output signal from an accelerometer. The accelerometer output signal may indicate acceleration and deceleration of a body part of a user, such as the user's wrist. Based on the accelerometer output signal, it may be determined that the body part of the user has decelerated to a minimum, e.g., substantially zero. With a determination that the body part has decelerated to the minimum, e.g., substantially zero, or has not accelerated beyond the minimum, e.g., substantially zero, the method may determine a reading from a pulse oximeter associated with the accelerometer. Advantageously, the pulse oximetry reading, or a reading from other sensors associated with the accelerometer, may be optimally accurate as motion artifact may be minimized. The pulse oximetry reading may be recorded for later query and/or rendered for the benefit of the user.

  • HOLLOW DRUG-FILLED STENT AND METHOD OF FORMING HOLLOW DRUG-FILLED STENT
    Publication number: 20150245930
    Abstract: A stent is formed from a wire having an outer member, a radiopaque member lining at least a portion of the outer member inner surface, and a lumen defined by the outer member inner surface or the radiopaque member inner surface. A substance is disposed in the lumen to be eluted through at least one opening disposed through the outer member to the lumen. The radiopaque member may be substantially continuous along the length of the wire or disposed only along portions of the wire such as crowns. In a method for making the stent, a composite wire including an outer member, a radiopaque intermediate member, and a core member is shaped into a stent pattern and processed to remove the core member and optionally portions of the radiopaque intermediate member, without damaging the outer member.
