|20150202424||INJECTION PORT WITH ARTICULATED STOPCOCK - The present invention is an injection port with an articulated stopcock allowing a syringe to be connected to an IV line and, depending upon the orientation of the stopcock, allow (1) bidirectional flow of fluid through the stopcock into the IV line, (2) no flow or (3) unidirectional flow of fluid through the stopcock and into or out of the IV line. The invention is particularly useful for using a syringe for aspirating an IV line and then injecting a medicine from the syringe into the IV line. Once a syringe is connected, the invention allows one-handed manipulation of the articulated stopcock into the three orientations by simply moving the connected syringe into one of the three orientations, thereby eliminating the need for using two hands—one to operate the syringe and the other to operate the handle.||07-23-2015|
|20140034169||Gangable Injection Port Holder - A gangable injection port holder including a series of receptacles for receiving swabable access valves that are themselves serially ganged together by tubing or complementary Luer slip connections. The receptacles are integrally formed onto a base with a side wall to allow the swabable access valves during use to be oriented vertically resting on the base or horizontally resting on the side wall. The base may be segmented, with each segment containing at least one of the receptacles. The segments may be easily snapped together in order to quickly assemble the desired number of receptacles intended to be used during a surgical procedure.||02-06-2014|
|20130190717||Cardioplegia Apparatus and Method - A microplegia console for controlling the delivery of cardioplegia to a patient, comprising an integrated display/touch screen for displaying cardioplegia information and patient information and allowing inputting of parameters via the display/touch screen into the console for computer-controlled perfusion of cardioplegia into the patient. The invention further comprises a method for delivery of cardioplegia to a patient, including defining and selecting a protocol from a displayed list and sequencing a series of the protocols. The invention also comprises a method for cardioplegia delivery to achieve aortic valve closure. Additionally, the invention comprises a method for activating an icon whereby, upon a first selection of the icon, displaying an indicia indicating that the icon has been first selected; and upon a second selection of the icon, activating the icon.||07-25-2013|
|20090076446||ADJUSTABLE CATHETER FOR DILATION IN THE EAR, NOSE OR THROAT - The improved balloon catheter includes a first tubular segment, which has multiple zones of differing malleability along its length. The catheter further includes a coaxially aligned hypotube formed of a malleable material, which is positioned within the lumen of the first tubular segment and extends from the distal end of the first tubular segment. In one embodiment the hypotube runs the length of the first tubular segment; while in another embodiment, the hypotube runs along only a portion of the length of the first tubular segment. A portion of the outer circumferential surface of the hypotube is permanently affixed and sealed to an inner circumferential surface of the first tubular segment in the vicinity of the distal end of the first tubular segment. The outer circumference of the distal end of the first tubular segment is gently tapered along its length so as to smoothly transition to the circumference of the hypotube. The hypotube terminates with an atraumatic tip and includes a balloon dilator affixed near the tip. An aperture near the tip of the hypotube fluidly connects the interior of the balloon with the lumen of the hypotube enabling the balloon to selectively expand and contract.||03-19-2009|
