  • Patent number: 11957886
    Abstract: A system includes a tubing set and a drive assembly. The tubing set includes inlet tubing couplable to a source of fluid, a valve coupled to the inlet tubing, a syringe coupled to the inlet tubing via the valve, and outlet tubing coupled to the valve. The valve is configured to allow fluid to be drawn from the source of fluid via the inlet tubing into a syringe body of the syringe and to be expelled from the syringe body and through the outlet tubing, and to prevent fluid from being drawn from the outlet tubing into the syringe body and to prevent fluid expelled from the syringe body from flowing through the inlet tubing. The drive assembly is configured to reversibly receive the tubing set such that a drive mechanism is engaged with a plunger of the syringe to reciprocally translate the plunger relative to the syringe body.

  • Patent number: 11938055
    Abstract: A method for treatment of a brain and/or spinal cord includes inserting a flexible catheter into a cerebrospinal fluid space, the flexible catheter including two lumens adapted to allow a fluid to circulate therein in a closed loop within the flexible catheter and the flexible catheter being adapted to be connected to a device for cooling and circulating the fluid. The cerebrospinal fluid in the cerebrospinal fluid space is cooled with the flexible catheter to enable selective central nervous system cooling. The functional status of the brain and/or spinal cord is monitored, and the treatment of the brain and/or spinal cord is modified to adjust for any change in the functional status of the brain and/or spinal cord.

  • Patent number: 11931528
    Abstract: A catheter configured to dynamically compensate for the impact of internal and external forces that act upon the catheter during use is disclosed. The catheter may include sensors configured to measure received forces on control cables that extend within the catheter. A controller, coupled to the sensors, may record received force measurements associated with a working position of a distal end of the catheter. The controller may monitor subsequently received forces to identify force variances that may deflect the distal end of the catheter from its working position and may apply a driving force to one or more of the control cables to minimize the force variances. Monitoring received forces during use and applying compensating drive forces may reduce deflection of the distal end of the catheter, increasing the accuracy and precision of an annuloplasty procedure while minimizing potential damage to cardiac tissue.

  • Patent number: 11931544
    Abstract: A bolus delivery device is provided that comprises a housing and a reservoir defined by an activation dome and a reservoir seat and disposed within the housing for receipt of a volume of a fluid. The bolus delivery device further comprises a bladder disposed in the housing that is in fluid communication with the reservoir for receipt of the fluid from the reservoir; an actuator; an inlet conduit in fluid communication with the reservoir for providing the fluid to the reservoir; and an outlet conduit in fluid communication with the bladder for providing the fluid to a patient. The actuator is in operative communication with the reservoir to initiate a flow of the fluid from the reservoir to the bladder. The bladder expands as the bladder receives the fluid and contracts as the bladder dispenses the fluid. An infusion assembly including a bolus delivery device also is provided.

  • Patent number: 11918763
    Abstract: Apparatus and associated methods relate to a catheter manipulation handle with user interface controls for steering a catheter in situ while providing an augmented (e.g., motorized, powered and tunable precision steering, and perforation safeguards) control and feedback user experience. In an illustrative example, the catheter manipulation handle may provide motor assisted operation to automatically rotate and/or deflect a distal tip of the catheter to steer and guide the distal tip to a target location in the patient's vasculature system. The augmented feedback may include, for example, haptic feedback via the handle. Haptic, audible, and/or visual feedback via the handle may indicate, for example, proximity or engagement of the distal tip with sensitive tissue. In some examples, the handle's augmented operation may advantageously amplify feedback signals to enhance the user's perception of the patient's safety with respect to the safe passage of the distal tip through the patient's vasculature.
