  • Patent number: 8449501
    Abstract: An enteral pump system for delivering medical fluids unidirectionally includes a disposable fluid delivery set having a repeatable compression portion and an enteral feeding pump. The repeatable compression portion is helically coiled around a central axis to define a cylindrical shape. The compression portion is configured to pump a large volume of medical fluids per stroke. The compressing portion includes at least two adjacent tubing walls joined around the central axis for repeatable compression. The enteral feeding pump is configured to repeatedly and reliably compress the compression portion of the fluid delivery set along the central axis. In operation, the compression portion is repeatably compressed without distortion along the central axis by the enteral feeding pump to flow unidirectionally through the fluid delivery set.

  • Patent number: 8439878
    Abstract: A thrombectomy catheter with a self-inflating proximal balloon having drug infusion capabilities is described. A self-inflating balloon is formed from an inflatable thin walled section of a flexible catheter tube. The self-inflating balloon includes a plurality of outflow orifices located about the peripheral circumference thereof and located proximal to an inflow gap interposed between a fluid jet emanator and the self-inflating balloon. The self-inflating balloon is inflated and expanded by internal operating pressures by proximal composite flow of fluid from the fluid jet emanator and entrained fluid from the inflow gap to uniformly space and position the outflow orifices of the self-inflating balloon in close proximity to the thrombus or vessel walls of a blood vessel. The thrombectomy catheter may be used for, among other things, thrombectomies, embolectomies, thrombus or vessel dilation, and for the delivery of drugs to a thrombus or vessel site.

  • Patent number: 8382722
    Abstract: A method of manufacturing a metal cannula is disclosed. The method includes the step of providing a metal cannula having a longitudinal axis and defining a fluid channel. Next, the metal cannula is pressed to substantially close the fluid channel and define a first segment and a second segment. In a next step, the metal cannula is cut to separate the first segment from the second segment of the metal cannula. Each of the first and second segments have a pressed edge. The pressed edge substantially seals the fluid channel and has two pressed corners. Afterwards, each of the pressed corners are cut from the pressed edge of the first segment to define a pair of side openings and a distal blunt edge on the first segment. The side openings are in fluid communication with the fluid channel.

  • Patent number: 8361039
    Abstract: A system is provided for performing injections in the ventricle of a patient. The system includes an injection catheter with a proximal and distal end. Importantly, a flexible array is mounted at the distal end of the injection catheter and is moveable between a protective configuration and a flared configuration. Also, a needle of variable length is mounted on the distal end of the injection catheter and is covered by the flexible array when the array is in its protective configuration. In order to manipulate the flexible array, a locking mechanism is mounted on the proximal end of the injection catheter for engagement with the flexible array. When selectively operated, the locking mechanism moves the array from its protective configuration to the flared configuration, holds the array in its flared configuration for an injection, and subsequently moves the array back to its protective configuration.
