The invention is a roller shade tube assembly with a main housing having a lumen divided into two sections by an internal spring stop. The distal end of the main housing has a recessed mounting cavity coupleable to a motor. The proximal end of the main housing has one or more interlocking fingers. A spring inside the proximal lumen abuts the spring stop. An inner guide cylinder is coupled to slide inside the main housing against the spring and coupled to a lumen of an auxiliary housing that is movably coupled to the main housing. The distal end of the auxiliary housing includes one or more complementary interlocking fingers and a second recessed mounting cavity at its proximal end. Wall mounting brackets on each side of the tube assembly are configured to fit into the recessed mounting cavities. A shade fabric is coupled to the roller shade tube assembly.

Micro gap roller shade system and method of installation

An improved catheter is provided for insertion into a trachea, blood vessel, bladder or urinary tract of a patient. The self cleaning catheter can be easily inserted and removed from the patient without retained, solid components falling into a patient's trachea, blood vessels, bladder, or urinary tract when the catheter is removed from the patient. The self cleaning catheter has a flexible cylindrical sleeve on the exterior of a cylindrical member that can be withdrawn to the interior of the catheter prior to removal from the patient's body. Alternatively, the catheter has a design allowing an end of the catheter to fold inward on itself prior to removal from the patient's body.

Self cleaning catheter and methods of use thereof

Methods and apparatus are provided for use in intraoperative and percutaneous procedures for supplying long-term retrograde perfusion of the myocardium via one or more conduits disposed between the left ventricle and the coronary venous vasculature. The conduits are of a selected size and number, and portions of the venous vasculature or coronary ostium are partially or completely occluded, to maintain a parameter related to the pressure attained in the venous vasculature to a value less than a predetermined value.

An apparatus ( ) and method of non-invasive monitoring of gut motility. An ingestible magnet ( M) is swallowed by the patient ( ) and then linear and rotational movement is directionally detected by an external compass ( ). In preferred form, movements of the magnet ( M) are recorded by a memory means ( ) and graphically presented ( ) over a period of predetermined time. An alternate embodiment includes multiple compasses (C C ) for directionally locating the magnet ( M) within the patient ( ).

Non-invasive gut motility monitor

Methods and apparatus for supplying retrograde perfusion of chronically ischemic myocardium by forming one or more transmural passageways between a cardiac chamber and the coronary venous vasculature. The placement, size and number of the passageways are selected, and portions of the venous vasculature or coronary ostium optionally partially or completely occluded, to maintain a parameter related to the pressure attained in the venous vasculature to a value less than a predetermined value.

Apparatus and methods are provided for use in open surgical and transluminal methods for supplying long-term retrograde perfusion of the myocardium via a conduit disposed between the left ventricle and the coronary sinus. In a first method, an opening is formed between the left ventricle and the coronary sinus, and the coronary ostium is partially occluded using a stent that prevents the pressure in the coronary sinus from exceeding a predetermined value. In an alternative method, a first end of a conduit is inserted transeptally through the right atrium and obliquely into the posterior septal endocardium of the left ventricle via the posterior pyramidal space, while a second end of the conduit is inserted into the coronary sinus via the coronary ostium. A pressure-limiting valve is included in the conduit. In either method, the outlet from the left ventricle to the coronary sinus may include a one-way valve to prevent backflow from the coronary sinus into the left ventricle during cardiac diastole.

A paint roller assembly includes a wire frame having a spindle on which a wire cage is rotatably mounted with end mounting bearing members. An outermost bearing member includes an annular wall provided with a flexible arm having a stop at its distal end. The stop normally abuts an end of a tubular paint roller to lock same against lengthwise movement. A paint barrier on the bearing member defines an area for momentary reception of the arm and stop during roller removal and installation procedures.

Hepatobiliary magnetic resonance imaging of a human or animal subject is enhanced by enterally administering to the subject an effective amount of a lipophilic contrast enhancing agent. Representative contrast enhancing agents include manganese mesoporphyrin, manganese deuteroporphyrin, manganese pheophorbide and manganese pyrophenophoribide, and, when administered orally, an enteric delivery agent.
