摘要:
A system and associated method for manipulating tissues and anatomical or other structures in medical applications for the purpose of treating diseases or disorders or other purposes. In one aspect, the system includes a delivery device configured to deploy and implant devices for compressing, distracting and/or retracting the lobes of a prostate.

A system and associated method for manipulating tissues and anatomical or other structures in medical applications for the purpose of treating diseases or disorders or other purposes. In one aspect, the system includes a delivery device configured to deploy and implant anchor devices for comprising, distracting and/or retracting the lobes of a prostate.
摘要:
A coiled anchor that secures to a connector as part of an anchor assembly is disclosed. The coiled anchor includes windings which capture and deform the connector between the windings and prevent the connector from disengaging from the coiled anchor once engaged.

摘要:
Transluminal methods and apparatus for causing arterial blood to flow through a vein of a mammalian patient, in a direction opposite normal venous blood flow, after an arterial blood containing conduit has been purposely or inadvertently connected to the vein. The method includes the use of a transluminally inserted vessel lumen occluding apparatus to at least partially block (e.g., occlude, embolize or close) the lumen of the vein at a location that is proximal to the location at which the arterial blood containing conduit is connected to the vein. The apparatus comprises a radially expandable lumen blocking device that is implantable in the vein lumen and catheters and other apparatus for implanting the radially expandable lumen blocking device into the lumen of the vein.
摘要:
Methods, devices and systems wherein a penetrating catheter or other penetrating device is used to penetrate into a target blood vessel, and wherein the target vessel is dilated prior to the penetration so as to improve the imaging, aiming at and/or penetration into the target vessel. In one embodiment, a tissue penetrating catheter device that is useable to penetrate from a blood vessel in which it is positioned to a target vessel comprises a flexible catheter advanceable into the first blood vessel and a tissue penetrator lumen adapted to receive an operative tissue penetrator which is usable to penetrate from the blood vessel to the target vessel when properly aimed. An imaging transducer may be fixedly mounted on or within the penetrating catheter to provide an imaging signal from which an image of the target vessel can be obtained. A target vessel dilating catheter is inserted into the target vessel and used to dilate the target vessel prior to imaging, aiming of the penetrator at and/or puncture thereof. Such vessel dilating catheters may comprise one or more occlusion member(s) (e.g., one or two balloons) to block flow through the target vessel and/or to isolate and pressurize a region of the vessel. Alternatively, the dilating catheter may comprise a dilating member that expands within the target vessel to cause a portion of the target vessel wall to enlarge, stretch, expand, bulge or otherwise dilate.
摘要:
Electro-anatomically navigated catheters (e.g., mapping catheters, tissue penetrating catheters, delivery catheters and/or sheaths) and associated methods whereby devices or substances may be delivered to specific locations within a patient's body and/or penetration tracts or passageways are formed at specific locations between anatomical structures. The catheters are equipped with sensors and a sensing field is created around the body of the patient. The sensor-equipped catheters are then inserted into the patient's body and the position of the catheter-mounted sensor(s) is/are observed on a display representing the sensing field. Apparatus may be included for propelling the catheter(s) to specific locations and/or specific rotation orientations, within the patient's body.
摘要:
A hemostasis valve which has a varying diameter. The hemostasis valve is actuated by a mechanism which provides mechanical advantage. Actuation of the hemostatis valve provides selective incremental sizing such that the valve will fit a variety of different intravascular devices.
