  • Patent number: 11000647
    Abstract: A controller and associated sensor system for augmenting the automatic delivery of drugs is provided. The controller and associated sensor system is based on the detection and determination of particular physical lifestyle events. As a specific example, a pump augmentation system includes a six-axis accelerometer sensor, a gyroscopic pitch sensor and a controller. The controller is configured to receive motion data from the six-axis accelerometer sensor and orientation data from the gyroscopic pitch sensor. The controller provides a pump instruction signal for changing a delivery rate of a drug to a user based on the motion data and the orientation data. When the pump is an insulin pump, the pump augmentation system is an insulin pump augmentation system and provides accurate insulin control for controlling blood glucose levels of a user.

  • Patent number: 10994077
    Abstract: Enhanced confirmations for programming of touchscreen infusion pumps reduce the likelihood of users confirming pump parameters that have been mistakenly programmed. Following programming of a given pump parameter, an icon or image intuitively related to the pump parameter can be displayed on the touchscreen. To confirm programming of the parameter, the user can be required to trace the icon on the touchscreen. The user will therefore necessarily associate the confirmation step with the parameter being programmed and be far more likely to realize if a mistake has been made because the user was intending to program a different parameter than with simple confirmations involving the press of a confirmation button.

  • Patent number: 10974032
    Abstract: A balloon structure includes a proximal balloon portion having a first internal volume, a distal balloon portion having a second internal volume, and a central balloon portion disposed between and joined with the proximal and distal balloon portions. The central balloon portion has a third internal volume isolated from the first and second internal volumes. A first lumen is associated with the third internal volume to direct pressure to the third internal volume for inflation of the central balloon portion. At least one second lumen is associated with the first and second internal volumes to direct pressure to the first and second internal volumes for inflation of the proximal balloon portion and the distal balloon portion. Whereby, upon inflation, the central balloon portion dilates, or delivers other treatments to tissue in the passage, with the proximal and distal balloon portions limiting movement of the balloon structure in the passage.

  • Patent number: 10932797
    Abstract: A method of removing vascular blockage includes providing a catheter system, comprising an outer catheter, a bypass catheter, and a guidewire. In the catheter system, the bypass catheter is slidably disposed within the outer catheter. The method includes positioning a distal end of the catheter system at a proximal end of an occlusion located within a vessel and moving the bypass catheter through the occlusion so that a medicated treatment solution may be delivered through the bypass catheter to an area of the brain or other tissue served by the vessel blocked by the occlusion. Both during and after the delivery of medicated treatment solution to the blocked part of the vessel with the bypass catheter, the physician may engage the occlusion with the perforated segment of the outer catheter so that a thrombolytic agent can be delivered at the occlusion to disintegrate it and then removing at least a portion of the occlusion from the vessel.
