摘要： A hydraulically actuated medical instrument includes an elongated shaft having proximal and distal ends, a hydraulically actuated end effector at the distal end of the shaft and a fluid flow path extending through the shaft to the end effector. The end effector may be directly manually operated by way of a handle located at the proximal end of the shaft or remotely, for example, via robotic controller. Articulation joints may be provided along the shaft, between the shaft and end effector or handle, or elsewhere. The hydraulic actuation of the present invention permits multiple axis instrument articulation, miniaturization and simplified instrument fabrication.

摘要： A transfer device usable in a system for intraluminal treatment of a selected site in a body of a patient in which the transfer device comprises an integral pump for pressurizing and circulating fluid through a fluid path defined by the transfer device and associated catheter. A removable fluid cartridge is provided including a reservoir from which fluid is drawn by the pump and into which fluid is returned after being circulated through the fluid path. The pump may be a peristaltic pump and the fluid cartridge may include an elongated fluid pick-up having an inlet through which fluid is introduced into the transfer device. The fluid pick-up is sized in length so that the inlet is always submerged in the fluid regardless of the orientation of the transfer device.

摘要： Apparatus and method are described for delivery of a treating element, such as a radiation source, through a catheter to a desired site in the intraluminal passageways of a patient, such as a coronary artery, for inhibiting the formation of scar tissue such as may occur in restenosis following balloon angioplasty. The apparatus includes an elongated flexible catheter tube having proximal and distal end portions, with a lumen extending therebetween, and a diameter sufficiently small for insertion in to a patient's intraluminal passageways. One or more treating elements, such as a capsule or pellet containing radioactive material, is positionable within the lumen and movable between the proximal and distal end portions under the force of liquid flowing through the lumen. A method for using such apparatus, including a method for using such apparatus simultaneously with a balloon angioplasty procedure, is disclosed.

摘要： Method and apparatus for retrieving an object such as a stent from a subject. A catheter supports two wire loops that can be manipulated from outside the subject to engage the object. By manipulating the catheter and the wire loops, the object can be captured and drawn inside a guide catheter through which the catheter is inserted. The catheter and attached stent can then be pulled from the subject.

摘要： A stent delivery system and method. A stent is routed to a desired position within a vessel within a subject. A delivery wire is routed out an opening in a delivery catheter and looped over a portion of the stent and then routed back inside the delivery catheter. At an extreme distal end of the stent, the wire again exits the delivery catheter, reengages the stent and is pushed back into the catheter center passageway. This compresses the stent into a form whereby the delivery catheter can be maneuvered through a vessel to position the stent. To release the stent from the delivery catheter, the delivery wire is retracted so that its distal end passes out both pair of openings in the delivery catheter allowing the stent to expand into engagement with the vessel wall.
摘要翻译：一种支架输送系统及方法。支架被路由到受试者内的血管内的期望位置。输送线从输送导管中的开口排出并且环绕在支架的一部分上，然后在输送导管内返回。在支架的最远端，线再次离开输送导管，重新接合支架并被推回到导管中心通道中。这将支架压缩成一种形式，由此输送导管可以通过容器操纵以定位支架。为了从输送导管释放支架，输送线缩回，使得其远端排出输送导管中的两对开口，允许支架膨胀成与血管壁接合。
