摘要： A pressure relief mechanism is incorporated into a modified syringe-type inflation device that may be coupled to a balloon catheter for inflating and deflating the balloon. An engagement mechanism selectively engages and disengages from a threaded shaft for advancing or withdrawing a plunger placed in slidable, yet sealing fit within a cylindrical chamber. In a first engaging position, the threaded shaft may be forcibly advanced or withdrawn in the cylindrical chamber, while in a second disengaged position, the plunger may be quickly pulled back.

摘要： The present invention generally relates to a medical device and procedure for accurately positioning a catheter across a desired region within a patient's vasculature. In particular, the present invention provides a hub assembly unit that allows a physician to precisely position a stent within a vessel utilizing a stent delivery catheter. The hub assembly unit includes a fine adjustment mechanism. The fine adjustment mechanism extends or contracts the length of the hub assembly unit in controlled incremental units. These controlled fine displacements are then translated directly to the stent delivery or balloon dilation catheter.

摘要： The present invention is drawn to a valve control accessory for use with a dual balloon stent delivery catheter. The accessory device includes a bifurcated fluid line adapted to connect to an inflation device using a proximal luer connector. Additional luer connectors at the distal ends of the main fluid line and branched fluid line are engaged to connect to the proximal ends of a bifurcated catheter shaft, allowing the fluid lines to be in fluid communication with a parent and sidebranch balloon respectively. In one embodiment, stopcocks are formed in both the main and sidebranch fluid lines to allow independent or simultaneous expansion of each balloon. A pressure indicator may be placed on either fluid line to indicate which line is under pressure.

摘要： An inflation device according to the present invention includes a barrel, a piston at least partially disposed within the barrel, and a collar surrounding at least a portion of the barrel. The piston includes a threaded portion. The collar and the barrel are axially movable with respect to one another, with the barrel being biased towards an equilibrium position within the collar by a collar spring. A nut is disposed at least partially within the barrel, the nut including an interior threaded surface and an exterior camming surface. The nut is movable along an axis substantially transverse to the barrel axis, and is biased towards a collar camming surface by a nut spring. When the barrel is in the equilibrium position, the nut is in a locking position in which the interior threaded surface engages the threaded portion of the piston. This prevents free movement of the piston within the barrel. When the barrel is moved from the equilibrium position the collar camming surface deflects the nut so that the piston is freely movable within the barrel.
摘要翻译：根据本发明的充气装置包括筒体，至少部分地设置在筒体内的活塞以及围绕筒体的至少一部分的套环。活塞包括螺纹部分。套环和筒体可相对于彼此轴向移动，筒体通过套环弹簧偏压到套环内的平衡位置。螺母至少部分地设置在筒体内，螺母包括内螺纹表面和外部凸轮表面。螺母可沿基本横向于筒轴线的轴线移动，并且通过螺母弹簧朝向凸缘凸轮表面偏置。当机筒处于平衡位置时，螺母处于锁定位置，在该位置，内螺纹表面接合活塞的螺纹部分。这防止活塞在筒体内的自由移动。当桶从平衡位置移动时，凸缘凸轮表面使螺母偏转，使得活塞在筒内自由移动。
