    摘要： A catheter device and methods useable to extract material from a body conduit, e.g., a blood vessel, are provided. The catheter comprises a flexible catheter advanceable into the body conduit, an opening in a wall of the catheter in fluid communication with a material collection chamber, and a controllably arcuate segment near the distal tip of the catheter and the opening. The catheter may include a sliding member, located within a lumen of the catheter, used to move the material entering the catheter through the arcuate segment opening, into the material collection chamber and away from said opening. The catheter may include a single mechanism utilized to both generate a vacuum to cause material to enter the catheter at the arcuate segment opening and also cause the sliding member to travel, inside the catheter, moving material away from the opening and into the material collection chamber.

    摘要： Methods and devices for implanting pacing electrodes or other apparatus, or for delivering substances, to the heart of other tissues within the body. A guided tissue penetrating catheter is inserted into a body lumen (e.g., blood vessel) or into a body cavity or space (e.g., the pericardial space) and a penetrator is advanced from the catheter to a target location. In some embodiments, a substance or an apparatus (such as an electrode) may be delivered through a lumen in the penetrator. In other embodiments, a guidewire may be advanced through the penetrator, the penetrating catheter may then be removed and an apparatus (e.g., electrode) may then be advanced over that guidewire. Also disclosed are various implantable electrodes and electrode anchoring apparatus.

    摘要： A device for delivering fluid to a patient including an exit port assembly adapted to connect to a transcutaneous patient access tool, a flow path extending from the exit port assembly, and a flow condition sensor assembly. The sensor assembly includes a resilient diaphragm having a first surface positioned against the flow path, a chamber wall defining a sensor chamber adjacent a second surface of the diaphragm, and at least one sensor arranged to provide a threshold signal when the second surface of the diaphragm expands into the chamber in response to at least one predetermined fluid flow condition occurring in the flow path. The sensor includes a first electrode secured on the diaphragm, a second electrode positioned in a fixed location with respect to the first electrode, and an impedance meter connected between the electrodes.

    摘要： The invention provides a wire guided aperture creating apparatus, an over-the-wire kit, and a method for creating a hole in adjacent portions of first and second anatomical conduits during a surgical procedure. The apparatus includes an elongated element having a guidewire lumen and an aperture creating assembly disposed near the distal end of the elongated element. In a further embodiment the device may include first and second elongated elements coupled via a coupler and an aperture creating assembly disposed between the elements. At least one of the elements includes a passage-defining element permitting passage therethrough of a first guidewire. In addition to the devices identified above, the kit includes a first guidewire for insertion into a lumen of the first vessel to an initial cutpoint and then through adjacent portions of sidewalls of the first and second vessels into a lumen of the second vessel. The method involves inserting a first guidewire into a lumen of a first vessel to an initial cutpoint and then though adjacent portions of sidewalls of the first vessel and a second vessel into a lumen of the second vessel. The method further involves providing a wire guided aperture creating apparatus as identified above, and inserting the device over the first guidewire such that the passage-defining element passes over the first guidewire.

    摘要： A device for delivering fluid, such as insulin for example, to a patient. The device includes an exit port assembly, a syringe-like reservoir including a side wall extending towards an outlet connected to the exit port assembly. A threaded lead screw is received in the reservoir and a plunger has an outer periphery linearly slideable along the side wall of the reservoir and an inner periphery threadedly received on the lead screw. The plunger is non-rotatable with respect to the side wall such that rotating the lead screw causes the plunger to advance within the reservoir and force fluid through the outlet. The device also includes a dispenser having a return element for causes rotation of the lead screw, and a shape memory element. A changeable length of the shape memory element decreasing from an uncharged length to a charged length resets the return element.
