摘要： A method of a forming a hollow, drug-eluting medical device includes utilizing a hollow wire having an outer member and a lumen of the outer member, and filling the lumen with a fluid to form a supported hollow wire. The supported hollow wire is shaped into a stent pattern. Openings are formed through the outer member. The supported hollow wire is processed to remove the fluid from the lumen of the outer member without adversely affecting the outer member, leaving the hollow wire shaped into a stent pattern. The lumen is filled with a biologically or pharmacologically active substance.

摘要： A catheter, such as a fractional flow reserve catheter, includes an elongate shaft having a pressure sensing wire extending to the distal portion of the elongate shaft. The wire has a pressure sensor mounted on the distal end for measuring a pressure of a fluid within lumen of vessel. The pressure sensor wire is disposed within a pocket formed adjacent to the pressure sensor thereby minimizing the profile of the catheter. Bending stresses experienced by a pressure sensor mounted to a fractional flow reserve catheter when tracking the catheter through the vasculature creates a distortion of the sensor resulting in an incorrect pressure reading or bend error. In order to isolate the sensor from bending stresses, the sensor is spaced apart from the pressure sensor wire to allow the pressure sensor and the pressure sensor wire to move independently from one another.
摘要翻译：诸如分数储备导管的导管包括细长轴，其具有延伸到细长轴的远端部分的压力感测线。导线具有安装在远端的压力传感器，用于测量容器内腔内的流体的压力。压力传感器线设置在邻近压力传感器形成的凹穴内，从而使导管的轮廓最小化。当通过脉管系统跟踪导管时，安装到分流储备导管上的压力传感器经历的弯曲应力会导致传感器的变形，从而导致不正确的压力读数或弯曲误差。为了将传感器与弯曲应力隔离，传感器与压力传感器线间隔开，以使压力传感器和压力传感器线彼此独立地移动。

摘要： A guide extension catheter 100 includes a proximal shaft 102, a distal shaft 104, and a plurality of perfusion openings 106. The distal shaft includes a jacket 118 and a helical coil structure 120 embedded in the jacket 118, the distal shaft defining a lumen. The plurality of perfusion openings are disposed though the jacket of the distal shaft between windings of the helical coil structure. The guide extension catheter provides additional back support to the guide catheter. The plurality of perfusion openings allow fluid communication between an area outside the guide extension catheter and the lumen.

摘要： An intracoronary catheter measures pressure distal to a lesion (Pd) and has a fluid lumen for administers adenosine to a patient's vasculature. A controller is configured to provide an injection of adenosine, wait for a period of time, measure Pd, and compare Pd to the Pd measured before the injection of the adenosine. If the difference between the pressures is small or below a threshold, the controller will stop further injections of adenosine because Pd has been determined to be at a relatively constant value. If the pressure difference is large or above a threshold, the controller will provide another adenosine injection, wait for a time period and again measure Pd and compare it to the previous Pd. This process will continue until the measured Pd reaches a relatively constant value.

摘要： A method for quickly and accurately identifying a digital file (102), specifically one that represents an audio file. The identification can be used for tracking royalty payments to copyright owners. A database stores features of various audio files and a globally unique identifier (GUID) for each file. Advantageously, the method allows a database to be updated in the case of a new audio file by storing its features and generating a new unique identifier for the new file. The file is sampled to generate a fingerprint (106) that is used to determine if the file matched a file stored in the database (108). Advantageously, any label used for the work is automatically updated if it appears to be in error.

摘要： Method and system provided for creating a dynamic playlist including meta-data having potential association with a respective content item configured to be played on a content player, and having dynamic addition of subtraction of playlist items. The system maintains a database of linkages between elements associated with content items as well as weighted linkages between elements and respective properties. The system is a hybrid content based and collaborative filtering system, wherein the insertion of a new item into the database results in the new item sharing preference weights and number of preferences associated with items pre-existing in the database. Thus, an initial input query list of items potentially results in the return of many content, called a "dynamic playlist", has a high correlation with the user's preference or with whatever other basis was used to frame the input list, and individual content items on the dynamic playlist may not have been previously experienced by the user.

摘要： A method and system for generating an acoustic fingerprint of a digital audio signal is presented. A received digital audio signal is downsampled, based upon a predetermined frequency, and then subdivided into a beginning portion, a middle portion and an end portion. A plurality of beginning frames, a plurality of middle frames and a plurality of end frames, each having a predetermined number of samples, are extracted from the beginning, middle and end portions of the downsampled, digital audio signal, respectively. A plurality of frame vectors, each having a plurality of spectral residual bands and a plurality of time domain features, are generated from the plurality of beginning, middle and end frames, and an acoustic fingerprint of the digital audio signal is created based on the plurality of frame vectors. The acoustic fingerprint is then stored in a database.
