摘要： Devices and methods are disclosed for protecting individuals from the sharp ends of medical objects following use on a patient. Such sharp objects include hypodermic needles, scalpel blades, cannulae, trocars, and the like. The invention utilizes a disposable protective cover for the used sharp. The protective cover is designed to surround and embed the sharp in a permanent cover that is blunt and will not permit further puncture or cutting with the sharp. In an embodiment, the protective cover also absorbs any fluids on or in the used sharp and prevents any fluids from escaping the protective cover. The sharp cover is configured to irreversibly lock, once closed. A refillable or replaceable dispenser dispenses the protective covers at points of use. A disposable receptacle receives the used sharp embedded in the protective cover. When the receptacle is full, the entire receptacle may be discarded in a medical waste container.

摘要： A prosthetic implant for treating a diseased aortic valve is described. The prosthetic implant includes a substantially tubular body configured to be positioned in an aorta of a patient, at or near the patient's aortic valve. The body includes a lumen extending through the body from a proximal end to a distal end of the body; and an adjustable frame surrounding the lumen. The prosthetic implant further includes at least one adjustable element located in or on the body and extending at least partially around a circumference of the lumen. The at least one adjustable element includes a shape memory material and is transformable, in response to application of an activation energy, from a first configuration to a second configuration, wherein the first configuration and second configuration differ in a size of at least one dimension of the at least one adjustable element. The at least one adjustable element may engage at least one of a root of the aorta, an annulus of the aortic valve, and the patient's left ventricle, when the at least one adjustable element is in the second configuration.

摘要： Systems and methods for removing obstructions from, delivering implantable devices or substances in or near and/or restoring flow through body lumens, such as blood vessel lumens. A catheter having a proximal portion of a first diameter and a distal portion of a second diameter (smaller than the first diameter) is advanced into a body lumen. The distal portion of the catheter is caused to expand to a diameter that is larger than the second diameter but no larger than the first diameter. A working device is then advanced out of the distal end of the catheter and used to remove obstructive matter, deliver an implantable device or substance and/or restore flow. The distal portion can be reduced in diameter prior to removal from the body.

摘要： Devices and methods are disclosed for achieving control and stabilization of bone fractures in mammals, most specifically humans. Stabilization and traction is often required to support fractured bones of the arms or legs. The devices and methods disclosed herein are especially useful in the emergency or military setting. The devices utilize a collapsible, inflatable member that may be expanded and locked into position. The frame or inflatable member is fabricated primarily from polymeric materials with low radiodensity. The limb contact regions are adjustable to fit a wide variety of limb sizes and fracture locations. The traction applied by the splint is adjustable, controllable and measurable. The traction splint is sufficiently compact that it will fit in a compartment of most emergency rescue vehicles, thus making it more available for use than standard traction splints in use today. The traction splint is either a separate device or integrated into a backboard.

摘要： A vascular graft comprises a perforate tubular compressible frame having a fabric liner disposed over at least a portion of the frames lumen. The graft may be used in combination with a base structure to form a bifurcated graft in situ. The base structure compresses a compressible frame having a fabric liner which defines a pair of divergent legs. The base structure is positioned within the aorta so that one leg enters each iliac. The tubular grafts can then be introduced into each leg to form the bifurcated structure. A graft delivery catheter includes a controllably flared sheath which facilitates recapture of a partially deployed graft.

摘要： A system for preventing air from entering a first catheter of a multi-catheter system. Air is prevented from entering the proximal end of the first catheter by an axially elongate chamber having an impeller, the chamber being affixed to the proximal end of the first catheter. The air is removed through a port near the centerline of the chamber. Liquid removed with the air is returned to the chamber to minimize liquid loss during the procedure. A second catheter inserted through the chamber and into the first catheter is unable to entrain gas into the first catheter because any gas that enters the chamber is routed to the centerline of the chamber where it is removed. Inflow of fluid from an external pump scrubs the second catheter shaft of air bubbles attached by surface tension.

摘要： A system is disclosed for removing gas bubbles from blood during circulatory assist procedures. Such bubbles are generated, along with particulate matter, in an extracorporeal circulatory bypass system by the pump, oxygenator and other components. Filters are used in the line to remove particulates and bubbles from the blood before they are pumped back to the patient but current filters are inefficient at removing small bubbles and debris that can cause neurological defects and renal and other organ failures in the patient. An active filter apparatus and method is disclosed that forces the bubbles to the center of the system where they are removed from the blood before the blood exits the filter. The filter comprises an axially elongate cylindrical shell with a blood inlet, a blood outlet and a gas outlet. A motor driven impeller spins the blood within the shell and forces the gas toward the center by centripetal force, utilizing the buoyancy effects of the bubbles in blood, whereby the bubbles can be bled off at the center of the filter element.
