Abstract: A drive mechanism for operating a suturing mechanism includes a user input displaceable through a range of motion and a linkage mechanically associated with the user input and with a shuttle transmitter of the suturing mechanism. The linkage converts displacements of the user input unidirectionally or bidirectionally into a sequence of operations of the shuttle transmitter including sufficient to perform a sequence of operations of the suturing mechanism to perform successive bidirectional stitching, with the shuttle transmitter penetrating tissue alternately with and without a shuttle needle attached.

Abstract: A suturing device includes a shuttle for holding a suture, a shuttle transmitter and a shuttle receiver. The shuttle transmitter includes a shuttle holder for holding the shuttle and a shuttle releaser displaceable relative to the shuttle holder for releasing the shuttle from the shuttle holder. The shuttle holder advances through a material at a first location while holding the shuttle until the shuttle engages the shuttle receiver. The shuttle releaser then releases the shuttle from the shuttle holder for withdrawal of the shuttle transmitter through the material, leaving the shuttle engaged with the shuttle receiver. The shuttle transmitter the penetrates the material at a second location opposite the shuttle receiver and retrieves the shuttle, holding it while withdrawing through the material at the second location. This sequence can be repeated to form a wide range of multi-stitch suture patterns for vascular closure and a wide range of other applications.

A catch insert is fixed to the interface unit body and is configured to lock onto a catch receptacle on the infusion pump upon rotation of the mechanical interface unit about the hinge axis while the hinge insert engages the hinge receptacle, so as to bring the tube into engagement with a peristaltic mechanism of the infusion pump in order to enable the peristaltic mechanism to propel a fluid through the tube.

Abstract: The present invention includes a finger-type peristaltic pump with a ribbed anvil. According to some embodiments, a finger type peristaltic pump may comprise a plurality of pressing fingers, an infusion tube and a passive interfacing mechanism. The passive interfacing mechanism may comprise a channel, groove or other suitable mount for placing and mounting an infusion tube such that the pressing fingers are positioned on one side of the tube and the ribbed anvil on the opposite side. The pressing fingers may be positioned to apply an approximately perpendicular force on the tube, pressing it against the ribbed anvil, thus causing a pumping action.

Abstract: A peristaltic pump which includes: (a) a plurality of effecters, actuated in a periodic manner upon by obstructive forces of a flexible infusion tube so as flow of infusion fluid is provided along said infusion tube, the magnitude of the obstructive forces are dependent upon the displacement of the moving effecters; and (b) a plurality of balancing magnets providing balancing forces upon one or all the moving effecters, the balancing forces at each point along the path of motion of the moving effecters being of approximately equal magnitude to that of the obstructive forces at the point, such that the parasitic output due to work performed against the obstructive forces is approximately zero and yield is maximized.

Abstract: A peristaltic pump includes a conduit having a first end tor receiving a fluid from a reservoir and a second end for delivering the fluid. A plurality of fingers are disposed at respective locations along a segment of the conduit and are configured to alternately compress and release the conduit at the locations. A cyclical pump mechanism is coupled to move the fingers between respective compressed and released positions in a spatio-temporal pattern so as to drive a predetermined quantity of the fluid through the segment of the conduit in each pump cycle. A motor is coupled to drive the pump mechanism. A controller is coupled to activate and deactivate the motor in alternation during each pump cycle with a duty cycle that varies within the pump cycle.

Abstract: An intravenous pump system includes an intravenous pump having an air bubble detector, a separate air trap module and a patient line. The air trap module is connectable to a set interface upon which the pump can operate. The air trap module includes an air chamber capable of receiving fluids and air, a plurality of valves controlling the flow of the fluids and air, and an air vent. The patient line is connectable to the air trap module and to a patient. The air trap module includes an actuator to control the state of the valves to enable, at least during a venting mode, the pump to push air out of the air chamber via the vent without disconnecting the patient from the patient line.

The body contains two or more finger-type valves (16) and a processor (22) configured to operate the valves according to a predetermined temporo-spatial pattern. The housing has a passageway (18) configured to receive a conduit. The housing has a first position in which a conduit in the passageway is positioned adjacent to the valve fingers, and a second position in which a conduit in the passageway is not adjacent to the valve fingers. The invention also provides a housing for use in the pump of the invention.

Abstract: The present invention discloses an anti-free flow mechanism for a finger-type peristaltic infusion pump (DDS) and methods for avoiding anti-free-flow. The mechanism comprises: a passive mechanical interface (MS) which integrally accommodates a portion of the flexible infusion tube, and an anti-free flow valve (AFFV) which is a spring-activated latch, which is incorporated within said MS. The maneuverable latch is secured in the MS either in CLOSED or OPEN configurations: in its CLOSED configuration no flow is provided, and in its OPEN configuration, a free flow is facilitated. Said anti-free flow mechanism is configured in a manner such that when the MS is not properly mounted in the DDS, said AFFV is automatically actuated via one or more integrated springs, to its CLOSED configuration. When the MS is properly mounted in the DDS, said latch is adapted to be automatically switched to the OPEN configuration.
