摘要: An apparatus for use as a catheter, a guidewire, a catheter sheath for use with catheter introducers or a drug infusion catheter/guidewire. The apparatus includes a flexible tubular member with an encasing covering the tubular member that creates a fluid-tight seal around the periphery of the tubular member. The tubular member is self-supporting and includes a plurality of apertures therein in a predetermined configuration to increase the flexibility of the tubular member.

摘要: Manufacturing processes for apparatus, including slotted hypotube, for use as a catheter, a guidewire, a catheter sheath for use with catheter introducers or a drug infusion catheter/guidewire are disclosed. The manufacturing process includes creating a pattern of slots or apertures in a flexible metallic tubular member, by processes including but not limited to, electrostatic discharge machining (EDM), chemical milling, ablation and laser cutting. These slots or apertures may be cut completely or partially through the wall of the flexible metallic tubular member. These manufacturing processes may include the additional step of encasing the flexible metallic member such that a fluid tight seal is formed around the periphery of the tubular member.

摘要: An intravascular catheter having a flow diffusing distal tip includes a plurality of cuts formed through the tubular wall thereof so as to define a plurality of generally U-shaped flaps, the flaps being disposed in at least one and preferably two axially displaced bands. When contrast fluid or the like is injected under pressure into the proximal end of the catheter, the flow of the liquid exits the openings in which the plurality of flaps are hinged, causing the flaps to vibrate and effectively eliminate any tendency for the contrast media to be expelled as a jet from the open distal end of the catheter. Having an open distal end allows the catheter to be passed over a guidewire.

摘要: A hemostasis valve including a collapsible membrane in a portion of a through-lumen. Fluid pressure in a chamber surrounding the collapsible membrane assists in sealing the collapsible membrane around an operating device inserted through the hemostasis valve. Different mechanisms for mechanically deforming the collapsible membrane to assist in sealing are disclosed. Also, a system for continuously flushing a vascular catheter connected to a hemostasis valve at a rate of 0.10 to 10.0 cubic centimeters per minute, and a hemostasis valve assembly including an expandable reservoir which stores liquid volume under pressure.

摘要: A medical device is provided having a needle or a catheter, insertable into a living body, which defines a plurality of holes in fluid communication with a central lumen. The holes may be of various patterns located and angled to create a desired injectate cloud pattern when an injectate is forced through the central lumen and through the plurality of holes. One embodiment provides various designs including a moveable sheath or stylet used to selectively occlude one or more of the holes while in use, thereby providing an operating physician a way to manipulate the cloud pattern anytime during the introduction of the injectate. A reducer may be used in conjunction with these needles which provides an increased degree of control when injecting very small quantities of fluid.

摘要: A medical monitoring apparatus designed to be implanted in the vascular system is capable of sensing and transmitting via a telemetry link to an external monitor both pressure and temperature information. An internally or externally powered microcircuit component is supported on a stent-like structure and adapted to be placed in the vascular system. Placement in the ventricular septum permits measurement of pressure and temperature in the left ventricle without introducing thrombus generating materials in the left ventricle.
