Abstract: A catheter for supplying liquid to the coronary sinus in a perfusion procedure comprising a tubular catheter body having an interior lumen, a proximal end, and a distal end; and an inflatable cuff (balloon) adjacent the distal end of the catheter. The cuff has a proximal end and a distal end, each of which encircle the catheter body and hermetically seal thereto. The cuff further comprises an elongated central section having a length of at least 1 inch. When the inflated cuff is positioned a sufficient distance into the coronary sinus to firmly retain the cuff therein, it blocks the left coronary vein where it meets the coronary sinus. Further, the cuff can comprise end panels defined between the central section and the proximal and distal cuff ends. The end panels have a shape which allows for flexure between the central section and the cuffs proximal and distal ends.

Abstract: A catheter for retrograde perfusion of the heart through the coronary sinus, which has an infusion lumen for introducing perfusion liquid into the heart, a retention means such as an inflatable balloon, and can have retention enhancements such as proximally sloping spikes, or barbed protuberances on the surface of the retention means to keep it firmly in place.

Abstract: A catheter assembly for the sterile introduction of a catheter into a body cavity is disclosed. The catheter assembly comprises a catheter, a stylet received within the catheter and a needle selectively mounted on one end of the catheter. Gripping means are incorporated on one or more of the stylet, needle or catheter to selectively mount the needle to the catheter.

Abstract: A trolling reel for raising and lowering a weighted control line to which a fishing line is detachably secured includes an electrically operated drive motor coupled to the reel for positioning the control line at a desired depth and securely holding the line when the motor is not actuated. The trolling apparatus is directly or remotely controlled and includes means indicating the length of control line extended. In one embodiment, control means are provided for fully raising the line by momentarily actuating a switch. In another embodiment, the control line is fabricated from a two-conductor electrical cable with a thermistor coupled to an end of the line which is extended at an angle from the lowered line by a spool to position the thermistor in proximity to the fishing lure. A remote temperature reading instrument is coupled to the control line through a slip ring assembly positioned on the reel and reel frame.

Abstract: A hose reel apparatus for garden and other type hoses which rewinds the hose after it has been pulled from the reel and automatically shuts off the flow of fluid through the hose and drains the fluid from the hose after it has been rewound. The apparatus includes a fluid motor powered by the fluid which is also directed through the hose, and fluid valving utilizing fluid pressure for stopping fluid flow through the hose. The valving is responsive to an increase in fluid pressure resulting from restriction in the rotation of the hose reel after the hose has been rewound.
