Delivery devices

Disclosed herein are devices for use in transplanting cells. The devices can include a housing defining a cavity; and a support structure separating the cavity into a cell chamber and a reservoir chamber, wherein the support structure comprises a membrane for fluid communication between the cell chamber and reservoir chamber. The cell chamber can define a first opening comprising a microstructure containing an array of micro-channels, each having a diameter to facilitate growth of vascular tissues; and an array of micro-reservoirs, each having a diameter to facilitate housing of cell aggregates individually. The membrane can define a surface area that is at least 50% of a total surface area of the support structure. Methods of treating a subject for a disease condition, such as diabetes, are also disclosed.

Event detection for drug delivery system

A drug delivery device may include an Inertial Measurement Unit (IMU) is provided. The IMU may include an accelerometer, a magnetometer, or a gyroscope. Motion parameters may be detected when the drug delivery device is shipped, being prepared for activation for use, or during use. The IMU may provide data indicative of a rapid deceleration, such as when a package containing the drug delivery device is dropped, or some other physical event experienced by the drug delivery device. The drug delivery device may also include internal or external pressure sensors or a blood glucose sensor that may coordinate with the IMU to provide additional feedback regarding the status of the device or user. A controller of the drug delivery device may generate a response depending on the particular parameters being monitored or may change device operational parameters as a result of detected system events.

Devices, systems, and methods for delivering therapeutic agents into a stomach wall

Embodiments of the invention provide swallowable devices, preparations and methods for delivering drugs and other therapeutic agents (TA) within the GI tract and in particular to an antrum wall (AW). Particular embodiments provide a swallowable device (SD) such as a capsule for delivering drugs or other TA into the AW. The SD may contain a pressure sensitive component or assembly which triggers release and insertion of a therapeutic agent preparation (TAP) comprising at least one TA into the AW in response to external pressure, such as pressure applied to the swallowable capsule or other SD by antrum contractions. Particular embodiments of the SD may be shaped so that they self-align within an antrum to properly orient before injection of the TAP into the AW. Embodiments of the invention are particularly useful for orally delivering drugs or other TAs which are degraded within the GI tract and require parenteral injection.

STABILIZED DRUG FORMULATIONS AND METHODS OF LOADING DRUG DELIVERY IMPLANTS

The present disclosure provides solid drug formulations, in particular to stabilized formulations of phosphonamidate-containing drugs, as well as methods for loading drug delivery devices with solid formulations.

MULTI-LAYER DRUG DELIVERY APPARATUS

Some target anatomies within the ear, nose and/or throat of a patient may be difficult to access and treat. To provide a means of treating such target anatomies over time, drug delivery devices that are sized to be positioned within a naturally occurring or man-made anatomical cavity or passageway are preloaded with active agent(s). The drug delivery devices are affixed directly to, or in the vicinity of, a target anatomy. Once affixed, the drug delivery devices are configured to deliver active agent(s) at desired dosage(s) to the target anatomy through controlled elution of the active agent(s) as various structural features of the drug delivery devices are bio-eliminated.

An implantable medical device is provided for controlled drug delivery within the bladder, or other body vesicle. The device may include at least one drug reservoir component comprising a drug; and a vesicle retention frame which comprises an elastic wire having a first end, an opposing second end, and an intermediate region therebetween, wherein the drug reservoir component is attached to the intermediate region of the vesicle retention frame. The retention frame prevents accidental voiding of the device from the bladder, and it preferably has a spring constant selected for the device to effectively stay in the bladder during urination while minimizing the irritation of the bladder.

DEVICE AND METHOD OF CREATING A FLUID CONTAINMENT FIELD FOR ADMINISTERING THERAPEUTICS TO A NERVE
20230225733 · 2023-07-20 ·

A severed nerve may be surgically rejoined and severed axons fused via sequential administrations of solutions. The solutions may include a priming solution comprising methylene blue in a Ca.sup.2+-free saline solution, a fusion solution comprising about 50% (w/w) PEG, and a sealing solution comprising Ca.sup.2+-containing saline. The PEG fusion solution may be applied in a nerve treatment device configured to isolate the injured segment of the nerve. The device may include a containment chamber for creating a fluid containment field around the anastomosis. The device may have slits, slots, and/or apertures in opposing endwalls of the device designed to receive the nerve. The device may have an open bath configuration or may include separable lower and upper bodies to create a closed bath configuration. The device may include one or more fluid ports in fluid communication with the containment chamber for introducing and/or removing fluid.

MODULAR WEARABLE DEVICE FOR PATIENT MONITORING AND DRUG ADMINISTRATION

A modular, wearable sensor and drug administration device is disclosed. The device includes removable modules such as sensors and drug administration apparatuses within a single wearable device. The device may be comfortable and modules may be easily removed and replaced. The sensors and drug administration devices may be used in concert to monitor and administer drug to a patient. Such a device may improve a patient's quality of life.

INGESTIBLE DEVICE FOR DELIVERY OF THERAPEUTIC AGENT TO THE GASTROINTESTINAL TRACT

Ingestible devices can directly deliver therapeutic agents to desired tissue(s) of the GI tract of a subject, such as the submucosa, the mucosa, and/or the mucus layer of the GI tract, and methods of using the same.
