摘要： A sealing device for sealing an opening of an apparatus. The sealing device has a head that defines a cavity and a neck that defines a passage disposed between the cavity at a first end of the neck and an aperture at a second end of the neck. The aperture is configured to collapse and expand, having a first diameter in a collapsed configuration and a second diameter in an expanded configuration. The interior surface of the neck includes an engagement interface that is configured to releasably engage with a spacer. When the engagement interface is engaged with the spacer, the neck is in the expanded configuration.

摘要： A safety cap for use with a needleless connector. The safety cap includes a body configured to at least partially enclose a head of the needleless connector (NC). The body is configured to achieve a first configuration that can be securely sealed to the NC and a second configuration that cannot be securely sealed to the NC. The second configuration is different from the first configuration. The safety cap also includes a detent in communication with the body which is configured to prevent the body from transitioning from the second configuration back to the first configuration.

摘要： A single use cap for connectors and corresponding method of use. The single use cap has a carrier with a body including a base that defines an opening separated from an end wall by a side wall. The opening leads into a cavity sized to receive a connector head. The single use cap also has an elastomeric sleeve releasably coupled to the carrier to span the opening. The elastomeric sleeve is configured to be transferred to the connector upon insertion of the head through the opening and at least partially into the cavity.

摘要： A stent for use in the nasolacrimal duct of a patient's eye. The stent is used to maintain and improve the patency of the nasolacrimal duct The stent uses a hollow shaft to create a fluid pathway from the punctum to the inferior meatus. Either the superior or inferior punctum can be selected for insertion of the stent. An inserter is used to position the flexible stent into position. A guidewire attached to the inserter is removed from the stent and it transforms from its collapsed state to its deployed state. A first anchor stabilizes the proximal end of the stent to the punctum and ampulla. A second anchor stabilizes the proximal end of the stent near the interior meatus. The second anchor can take any of several deployed shapes, such as a pigtail or fins.

摘要： 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.

摘要： A fluid pump for medical applications. The pump includes a flexible cassette containing two pump chambers of differing volume, each chamber having a dedicated piston. The first piston pushes fluid from the first chamber to the second, and the second piston pushes fluid from the second chamber and out of the pump. Three valves are coordinated with the action of the pistons to control fluid flow into and out of the pump chambers by applying and releasing pressure to and from specific points of the flexible cassette. A control system controls the operation of the pistons and valves and directs the pistons to be advanced according to a time-varying velocity profile. The first pump chamber passively fills and then rapidly expels the collected fluid into the second chamber at low pressure. The second chamber, once filled, expels the fluid downstream at high pressure, producing a pulsatile pressure profile.

摘要： 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.

摘要： The present invention relates to a retrograde cardioplegia catheter for the delivery of a cardioplegia solution to a patient's heart during open heart surgery. The catheter includes a flexible, elongated cannula having a proximal and a distal end. The cannula includes at least two lumens, the primary lumen being utilized to deliver cardioplegia solution. Typical of retrograde catheters, a sealing member is positioned and secured about the distal end of the cannula. In contrast to conventional catheters, however, the sealing member is comprised of (i) a thin-walled membrane that defines an interior chamber and (ii) a compressible, resilient form positioned within such chamber to fully support the membrane. The resilient form is in an expanded state when relaxed. The resilient form of the present invention enables the distribution of a consistent, definable force across the surface of the semi-rigid sealing member, whereby the resilient form empowers the sealing member of the present invention to overcome migratory tendencies of air- and fluid-filled sealing members typical of conventional retrograde cardioplegia catheters.
