    • A balloon catheter which has an elongate shaft with an inflatable balloon connected to its distal end and a manifold connected to its proximal end. The manifold may be fixedly or removably attached to the shaft and includes a barrel with a plunger movably disposed inside it. The manifold may be held with one hand and the plunger may be actuated with one finger or thumb on the same hand. The barrel may have an internal volume of less than 5 cc and an internal diameter of less than 0.25 inches. The catheter also has a prep port which may be connected at or near the proximal end of the catheter. The prep port facilitates prepping of the catheter system. A seal (e.g. a releasable cap or a valve) may be connected to the prep port for sealing off the prep port during use. A pressure transducer may be mounted to the catheter (e.g. on the shaft, the manifold, the prep port, or the seal) to permit measurement of the pressure within the inflation lumen and the balloon. The pressure transducer may be operably connected to a pressure display and the display may be connected to the proximal end of the catheter or may be remotely located from the catheter. Data may be transmitted to the remote display by wire or wireless transmission (e.g. infrared, radio frequency, or magnetic transmission). Alternate embodiments and methods of use are also disclosed.
    • 一种气囊导管,其具有连接到其远端的可膨胀气囊的细长轴和连接到其近端的歧管。 歧管可以固定地或可移除地附接到轴上并且包括具有可移动地设置在其内的柱塞的筒。 歧管可以用一只手握住,并且柱塞可以用一只手指或拇指在同一只手上致动。 枪管可具有小于5cc的内部容积和小于0.25英寸的内径。 该导管还具有可在导管的近端处或其附近连接的制备端口。 准备端口有利于导管系统的准备。 可以将密封件(例如可释放盖或阀)连接到准备端口,以在使用期间密封准备端口。 压力换能器可以安装到导管(例如在轴,歧管,制备端口或密封件上),以允许测量充气腔和气囊内的压力。 压力传感器可以可操作地连接到压力显示器,并且显示器可以连接到导管的近端,或者可以远离导管定位。 数据可以通过有线或无线传输(例如红外线,射频或磁性传输)发送到远程显示器。 还公开了替代实施例和使用方法。

    • A sheath for facilitating a guide wire exchange is defined by an elongated tubular member having a proximal end, a distal end and a single thru lumen. The sheath also has a proximal insertion opening and a distal insertion opening in communication with the thru lumen. The sheath includes a distal guide segment for "single operator" insertion and a peelable extent for peelably removing the sheath after use. The distal guide segment is formed along a distal portion of the elongated tubular member. The sheath is inserted along a pre-inserted guide wire by inserting a proximal end of the pre-inserted guide wire through a guide lumen of the distal guide segment. The sheath is advanced distally along the pre-inserted guide wire to a desired position and thereafter the pre-inserted guide wire is withdrawn. A re-shaped guide wire or substitute guide wire is inserted through the proximal insertion opening and advanced through the thru lumen of the sheath to a treatment site. The sheath is withdrawn while peelably removing the tubular member from the inserted guide wire.
    • 用于促进导丝交换的护套由具有近端,远端和单通道的细长管状构件限定。 护套还具有近端插入开口和与穿过腔连通的远侧插入开口。 鞘包括用于“单操作者”插入的远侧引导部分和用于在使用后可剥离地去除鞘的可剥离范围。 远侧引导段沿着细长管状构件的远端部分形成。 通过将预先插入的导丝的近端插入远侧引导段的引导内腔,沿着预先插入的导丝插入护套。 护套沿着预插入的导丝线向远侧推进到期望的位置,此后将预先插入的导丝线取出。 重新形状的导丝或替代导丝插入穿过近侧插入口并穿过鞘的通过腔进入治疗部位。 护套被取出,同时从插入的导丝上可剥离地移除管状构件。

    • An inflation device includes a syringe forming a cylindrical chamber containing a plunger carrying a stopper or piston arrangement. The chamber is designed to contain an inflation fluid and is in fluid communication with the lumen of a balloon catheter. Movement of the plunger within the chamber will increase or decrease the pressure of the fluid within the chamber and lumen, thereby inflating or deflating the balloon at the distal end of the catheter. A pressure sensor is mounted to the housing in fluid communication with the lumen and is electrically connected to a battery-operated transmitter. The transmitter broadcasts signals representing pressure within the lumen and balloon to a remote receiver. The receiver includes a microprocessor containing a clock and operable to display time and pressure data. A flexible insulator strip is interposed between the battery and the transmitter circuit to prevent operation of the transmitter until desired by the cardiologist. The housing of the inflation device may be opened to remove the batteries for separate disposal and to render the circuit inoperative to prevent reuse. A look-up table associated with the microprocessor permits display of balloon diameter during the procedure.
