  • Patent number: 10898649
    Abstract: In a general aspect, a syringe terminates the dispensing of a fluid based on a force applied to a plunger member of the syringe. In some aspects, a plunger member of a syringe includes a top portion, a bottom portion, and a contact portion. The top and bottom portions are in contact with the contact portion, and the bottom portion has a length greater than or equal to a length of the top portion. The contact portion permits the top portion to move independent of the bottom portion in response to a stress in the contact portion exceeding a critical stress. The stress in the contact portion is based on a first force applied to the top portion and a second force opposite the first force applied to the bottom portion.

  • Patent number: 10881622
    Abstract: Technologies are described for delivery of compounds to aid in weight management. A transdermal microdispenser based system may deliver weight management compounds through the time and dose specific administration of appetite suppression, metabolic enhancers, and satiation compounds. The transdermal delivery system may be controlled based on data associated with subject such as calorie intake, physical activity, satiation, and hunger. The system may be integrated with medical monitoring or fitness tracking systems. Delivery of the compounds may be distributed over the course of a day at selected or adjusted doses to be safe and effective for their specific modality. For example, appetite suppressants may be delivered during periods of the day when cravings occur, satiation compounds may be delivered to coincide with meals, and metabolic stimulators may be delivered at times to optimally increase metabolism based on caloric balance. Control factors may also be predictive to prevent the onset of hunger.

  • Patent number: 10869989
    Abstract: A closed loop catheter useable for heat exchange is manufactured by forming a plurality of generally transverse bore holes though a flexible, multilumen catheter body, lacing a tube trough the bore holes so that loops of the tube protrude from the catheter body, connecting one end of the tube to an inflow lumen of the catheter and connecting the other end of the tube to an outflow lumen of the catheter. A heated or cooled heat exchange medium may then be circulated through the tube while the catheter is inserted in the vasculature of a subject, thereby resulting in heat exchange between the subject's flowing blood and the heat exchange medium being circulated through the tube.
