Abstract

Systems and methods are described for implementing or deploying medical or veterinary utility modules (a) operable for mooring at least partly within a digestive tract, (b) small enough to pass through the tract per vias naturales and including a wireless-control component, (c) having one or more attachment protrusions positionable adjacent to a mucous membrane, (d) configured to facilitate redundant modes of attachment, (e) facilitating a “primary” material supply deployable within a stomach for an extended and/or controllable period, (f) moored by one or more adaptable extender modules supported by a subject'"'"'s head or neck, and/or (g) configured to facilitate supporting at least a sensor within a subject'"'"'s body lumen for up to a day or more.

Claims

1. A medical or veterinary system comprising:

a medical or veterinary utility module small enough to pass through a digestive tract of a subject having an oral cavity per vias naturales that includes at least a wireless-control component having at least an engaging state and a disengaging state, the engaging state operable to cause the medical or veterinary utility module at least to remain within a portion of the digestive tract, the disengaging state allowing the medical or veterinary utility module to exit the digestive tract of the subject per vias naturales, in which the wireless-control component includes at least a disengagement-inducing actuator located within the utility module and circuitry for invoking the disengagement-inducing actuator responsive to one or more module disengagement signals;

one or more mooring modules configured for attachment within the oral cavity that are operably coupled to one or more tethers operable to support the utility module in the digestive tract for more than a day; and

at least one reservoir that is configured to be moored within the oral cavity having one or more flow paths operable to guide a therapeutic material to one or more dispensers that are operably associated with the utility module.

2. A medical or veterinary system comprising:

a medical or veterinary utility module small enough to pass through a digestive tract of a subject per vias naturales, the medical or veterinary utility module including at least a wireless-control component having at least an engaging state and a disengaging state, the engaging state operable to cause the medical or veterinary utility module at least to remain within a portion of the digestive tract, the disengaging state allowing the medical or veterinary utility module to exit the digestive tract per vias naturales, in which the wireless-control component includes;

a ferromagnetic element generating a magnetic field;

a conductive coil;

a current source operable for generating a current in the conductive coil at least partly in opposition to the magnetic field; and

a disengagement-inducing actuator that facilitates detachment of the utility module from the digestive tract in response to one or more dispenser release signals.

3. A medical or veterinary system comprising:

a medical or veterinary utility module small enough to pass through a digestive tract of a subject having an oral cavity per vias naturales that includes at least a wireless-control component having at least an engaging state and a disengaging state, the engaging state operable to cause the medical or veterinary utility module at least to remain within a portion of the digestive tract, the disengaging state allowing the medial or veterinary utility module to exit the digestive tract per vias naturales, in which the wireless-control component includes at least a dispenser-relating actuator and circuitry for invoking the dispenser-releasing actuator responsive to one or more dispenser release signals;

one or more mooring modules configured for attachment within the oral cavity that are operably coupled to one or more tethers operable to support the utility module in the digestive tract for more than a day; and

at least one reservoir that is configured to be moored within the oral cavity having one or more flow paths operable to guide a therapeutic material to one or more dispensers that are operably associated with the utility module.

4. A medical or veterinary system comprising:

a medical or veterinary utility module small enough to pass through a digestive tract of a subject having an oral cavity per vias naturales that includes at least a wireless-control component having at least an engaging state and a disengaging state, the engaging state operable to cause the medical or veterinary utility module at least to remain within a portion of the digestive tract, the disengaging state allowing the medial or veterinary utility module to exit the digestive tract per vias naturales, in which the wireless-control component includes at least a ferromagnetic element generating a magnetic field;

a conductive coil; and

a current source operable for generating a current in the conductive coil at least partly in opposition to the magnetic field;

one or more dispensers responsive to one or more wireless signals selected from the group consisting of an adhesive-containing dispenser, an adhesive-solvent-containing dispenser, an anticoagulant-agent-containing dispenser, and an antibiotic-containing dispenser, the one or more dispensers having one or more flow paths operable to guide a therapeutic material from a reservoir that is configured to be moored within the oral cavity to the utility module;

one or more actuators selected from the group consisting of a disengagement-inducing actuator, a dispenser-releasing actuator, a reservoir-opening actuator, and dosage-adjustment actuator;

circuitry for controlling the one or more actuators, the current source, and the one or more dispensers responsive to one or more wireless signals, selectively operable to maintain the wireless-control component in one or more modes of the engaging state for longer than a week;

one or more mooring modules having a median width W and a length L>

4*W that are configured for attachment within the oral cavity; and

one or more tethers that are operably coupled to the one or more mooring modules and operable to support the utility module in the digestive tract for more than a day.

5. The medical or veterinary system of claim 4, further comprising:

one or more magnetic-field-generating elements operable to influence at least a first one of the one or more wireless signals from outside the digestive tract;

one or more radio frequency communication elements operable to influence at least a second one of the one or more wireless signals from outside the digestive tract; and

a remote module operable for receiving information from the medical or veterinary utility module and for receiving status-indicative data from the medical or veterinary utility module.
