    • A surgical closure method utilizes a surgical device including an elongate tube, a flexible web member disposed in a collapsed configuration inside the tube, and a push rod disposed at least partially inside the tube for pushing the web member from the tube. A distal end portion of the tube is inserted through an opening or wound in a wall of a hollow body organ. The rod is pushed in a distal direction along the tube to eject the web member from the distal end of the tube. The ejected web member is expanded from the collapsed configuration to an expanded configuration. The expanded web member is placed in contact with the wall of the organ over the opening or wound. Subsequently the expanded web member is attached to the wall of the organ.
    • 手术闭合方法利用外科装置,其包括细长管,设置在管内的收缩构造的柔性腹板构件,以及至少部分地设置在管内部的推杆,用于将腹板构件从管中推动。 管的远端部分穿过开口插入或缠绕在中空体器官的壁中。 杆沿着管的远端方向推动,以从管的远端排出腹板构件。 排出的网构件从折叠构型扩展到扩展构型。 膨胀的腹板构件放置在开口或伤口上与器官的壁接触。 随后,膨胀的腹板构件附着到器官的壁上。

    • Described herein are various methods and apparatuses for delivering stents or conduits and other devices into the myocardium of a patient. One preferred stent delivery system provides access to the insertion site in the myocardium by advancing a delivery catheter through a blockage in a coronary artery, or around the blockage through a coronary vein or through a channel or tunnel formed around the blockage. In one embodiment, once the distal end of the delivery catheter is adjacent the myocardium, an angled bend is created in the catheter by actuating expandable steering guides mounted to the catheter which cooperate with the walls of the blood vessel to cause the catheter to turn. Then, a guidewire is advanced through the delivery catheter and into the myocardium. In another embodiment, a tip-deflecting pull wire extends from the distal end of the delivery catheter which may be actuated to turn towards and then inserted into the myocardium. In another embodiment, an exit port facing the insertion site is provided within the catheter or a balloon mounted on the catheter so that a guidewire may be directed through a lumen and out the exit port into the:.myocardium. Once the guidewire punctures into the myocardium, the guidewire is anchored using barbs, balloons or other actuatable members to secure the guidewire to the myocardium. Subsequently, using a push-pull mechanism, stents and other medical devices can be advanced over the guidewire into the myocardium.
    • 本文描述了用于将支架或管道和其他装置输送到患者的心肌中的各种方法和装置。 一个优选的支架递送系统通过使输送导管通过冠状动脉阻塞或通过冠状静脉或通过在阻塞周围形成的通道或隧道周围的阻塞来推进进入心肌中的插入部位。 在一个实施例中,一旦输送导管的远端与心肌相邻,则通过致动安装到导管的可扩展转向引导件,在导管中产生成角度的弯曲部,其与血管的壁配合以使导管转动。 然后,导丝通过输送导管进入心肌。 在另一个实施例中,尖端偏转拉线从输送导管的远端延伸,可以被致动以转向然后插入心肌。 在另一个实施例中,面向插入部位的出口端口设置在导管内或安装在导管上的球囊上,使得导丝线可以被引导通过内腔并且离开出口进入心肌。 一旦导丝穿刺入心肌,就使用倒刺,气球或其他可致动部件来固定导丝,以将导丝固定到心肌。 随后,使用推拉机构,支架和其他医疗装置可以在导丝上前进进入心肌。

    • Described herein is a catheter system for delivering an L-shaped conduit into the body of a patient between the left ventricle and coronary artery. A shunt preferably made of semirigid material is inserted into the lumen of a delivery catheter. The delivery catheter is advanced within the patient until its distal end is located adjacent to the desired insertion site, which is preferably the junction between a coronary artery and passageway formed in the myocardium between the left ventricle and coronary artery. A proximal section of the shunt is first advanced out of the delivery catheter into the myocardial passageway. A distal section of the shunt is advanced into the coronary artery, preferably by advancing the distal section of the shunt into the myocardial passageway and then pulling the distal section back into the coronary artery, or by pushing the distal section of the shunt in a folded configuration out of the delivery catheter into the coronary artery. In one embodiment, the shunt is made of a collapsible material for insertion into the delivery catheter, the shunt expanding upon removal from the delivery catheter.
    • 这里描述的是用于将L形导管输送到左心室和冠状动脉之间的患者体内的导管系统。 优选由半刚性材料制成的分流器插入输送导管的内腔中。 输送导管在患者体内前进,直到其远端位于所需插入位置附近,该位置优选为冠状动脉与左心室和冠状动脉之间的心肌中形成的通路之间的连接点。 分流器的近端部分首先从输送导管进入心肌通道。 分流器的远端部分推进到冠状动脉中,优选地通过使分流器的远端部分进入心肌通道,然后将远端部分拉回冠状动脉,或者通过将分流器的远端部分推向折叠 配置输出导管进入冠状动脉。 在一个实施例中,分流器由用于插入输送导管的可折叠材料制成,在从输送导管移除时分流器膨胀。
