  • Publication number: 20230125035
    Abstract: A cannula insertion system for cannulating a blood vessel includes a cannula system having a cannula that defines a cannula lumen and has a distal and proximal end. The system includes a cannula insertion device for coupling with the system that includes a dilator having a dilator body and a dilator lumen; a needle having a needle body and a needle lumen, the needle being translatable within the dilator lumen along a first direction; a movable dilator actuator configured to cause the dilator to move along the first direction; a movable needle actuator configured to cause movement of the needle along the first direction; and a housing defining housing recess. The housing recess is configured to receive the cannula system, the dilator, and the needle. The needle and the dilator are configured to be moved within the cannula lumen along the first direction.

  • Publication number: 20220193318
    Abstract: Disclosed are devices and methods directed to oxygenators for use in extracorporeal circuits for supporting a fetus. An oxygenator for use with an extracorporeal circuit includes a housing defining a cavity therein and a gas exchanger disposed within the interior cavity. The cavity is configured to receive blood a fetus. The gas exchanger is configured to receive a sweep gas and further configured to contact the blood within the cavity, such that at least oxygen gas and carbon dioxide gas is permitted to diffuse between the blood and the gas exchanger.

  • Patent number: 6916220
    Abstract: A pivotal fin system, for use with an aquafoil, such as surfboards, body boards, wave skis, sail boards, wake boards and the like, comprising a pot (3) and a fin (2), having a tab (18) extending from the base (17) of the fin (2). The pot (3) has a central slot (11) and is mounted in the board (23) with the opening of the central slot (11) flush with the board (23). The slot (11) has a releasable locking means (6 & 7) therein, and the tab (18) has a connection means (21 & 22), which is releasably engaged by locking means (6 & 7). Preferably the releasable locking means (6 & 7) is a substantially c-shaped clamp, and the connection means (21 & 22) has a recess or recesses (22) behind a bulbous extension (21), which is engaged in the c-shaped clamp, with arms (5) of the c-shaped clamp engaging in the recess or recesses (22).

  • Patent number: 5649846
    Abstract: A pivotable fin system, for use with an aquafoil such as a surfboard, comprising a plug and a fin having a main portion and a tab. The plug mounts in the surfboard, and has a central slot for receiving the tab. The tab has a reverse taper that matches a reverse taper in the central slot. The tab has at least one vertical slot which compresses to allow the tab to be mounted in the central slot, the vertical slot expanding once the tab is fully inserted into the central slot, the tab then securely held in place by the matching reverse tapers of central slot and tab. The tab has at least one tab cut for allowing the main portion of the fin to pivot with respect to the tab, allowing the main portion of the fin to self-align to a position where it reduces drag and cavitation.
