Abstract: A method and apparatus having a backing implement for removably holding a swimming pool tile cleaner. A scrubbing member removably attaches to the backing implement, wherein the scrubbing material is operable for cleaning said swimming pool tile. A scrubbing member attachment implement attaches the scrubbing member to said backing implement. A mounting mechanism enables the backing implement and scrubbing member to removably attach to a frame of a debris collecting tool operable for said cleaning the swimming pool tile, wherein said cleaning including applying a surface tension releaser to a body of water in a swimming pool and working the debris collecting tool with removable cleaning implement around the body of water to clean the pool tile and collect debris.

Abstract: A key able to accept a label for a keypad used in controlling electrically operated devices, wherein the key structure accepts and secures an interchangeable label, and which forms an impermeable barrier to the electrical contacts of a programmable circuit board.

Abstract: A method and system for magnetic resonance imaging comprises applying at least one radiofrequency magnetization transfer (MT) pulse to a coronary venous region of a subject positioned within a magnetic field, and acquiring magnetic resonance imaging data from the coronary venous region to produce an image of a coronary venous structure. This technique can be utilized as part of a 3D free-breathing, ECG-triggered gradient-echo Cartesian acquisition of the coronary region. One or more magnetization transfer (MT) preparation pulses are used to enhance the contrast between venous blood and myocardium. The MT preparation results in myocardial signal suppression without any significant signal loss in the arterial or venous blood so as to maintain venous blood signal-to-noise ratio while improving contrast between myocardium and veins. The image of a coronary venous structure can be acquired in connection with an interventional cardiovascular procedure, such as a cardiac resynchronization therapy.

The coronary venous structure can comprise one or more of a coronary sinus, a lateral vein and a posterior vein.
