  • Patent number: 9962483
    Abstract: Flow control devices and methods using the flow control devices are provided. In a general embodiment, a cassette includes a housing having a constrictor, a tube attached to the housing and positioned through the constrictor, and a ball positioned inside the tube. The constrictor can be constructed and arranged to prevent the ball from moving through the tube at the location proximate the constrictor. The ball can prevent fluid flow in one position and be dislodged to allow fluid flow when the cassette is positioned inside a pumping device. As a result, the cassette is designed to prevent free flow of fluid when an enteral feeding tube set is not installed in a pumping device.

  • Patent number: 9801642
    Abstract: A thrombectomy catheter deployment for operation of a thrombectomy catheter may include a stand alone drive unit and a disposable pump/catheter assembly which is manually placed into a carriage assembly in the drive unit. The pump/catheter assembly may have a plurality of preconnected components including a tubular structure and a thrombectomy catheter connected thereto. A barcode reader may sense specific operational data pertaining to an individual pump and may provide an interface for operation of the reciprocating linear actuator.

  • Patent number: 9468716
    Abstract: Flow control devices.—In a general embodiment, the present disclosure provides a cassette (30) comprising a housing having a flow restrictor (34), and a tube (36) attached to the housing and positioned adjacent the flow restrictor. The flow restrictor may be so constructed and arranged to rotate from a first position in which the flow restrictor prevents fluid flow through the tube to a second position in which fluid is able to flow through the tube when the cassette is positioned inside a pumping device. As a result, the cassette is designed to prevent free flow of fluid when an enteral feeding tube set is not installed in a pumping device.

  • Patent number: 9161765
    Abstract: A thrombectomy catheter deployment for operation of a thrombectomy catheter includes a stand alone drive unit and a disposable pump/catheter assembly which is manually placed into a carriage assembly in the drive unit. The pump/catheter assembly has a plurality of preconnected components including tubular structure and a thrombectomy catheter connected thereto and is transported into or out of the interior of the drive unit for automatic high pressure pump piston head engagement or disengagement with a reciprocating linear actuator and for automatic engagement of disengagement of an effluent waste tube with a roller pump. A barcode reader senses specific operational data pertaining to an individual pump and provides an interface for operation of the reciprocating linear actuator.

  • Patent number: 8491523
    Abstract: Methods of conducting thrombectomy procedures and deploying a thrombectomy catheter are disclosed. A thrombectomy procedure is conducted with a thrombectomy catheter deployment system. A drive unit configured to operate an infusion pump is provided. The drive unit is operable according to one or more operating modes. A preconnected and consolidated pump and catheter assembly configured for loading in the drive unit is also provided. The assembly is separate from the drive unit prior to loading. The infusion pump and a catheter of the assembly are in communication prior to loading. The assembly provides one or more digital instructions to the drive unit. The drive unit is operable according to the one or more operating modes referenced by the one or more digital instructions. The assembly is loaded into the drive unit, and the drive unit is engaged to the infusion pump for operation of the infusion pump.

  • Publication number: 20110208205
    Abstract: A thrombectomy catheter deployment system which greatly simplifies setup procedures and operation of a thrombectomy catheter includes a stand alone drive unit and a disposable pump/catheter assembly which is manually placed into a carriage assembly in the drive unit. The pump/catheter assembly has a plurality of preconnected components including tubular structure and a thrombectomy catheter connected thereto and is transported into or out of the interior of the drive unit for automatic high pressure pump piston head engagement or disengagement with a reciprocating linear actuator and for automatic engagement or disengagement of an effluent waste tube with a roller pump. A barcode reader senses specific operational data pertaining to an individual pump and provides an interface for operation of the reciprocating linear actuator. A bubble trap incorporated for effective debubbling of saline solution is closely coupled to an insert molded pump having an improved valve arrangement.
