Disclosed are methods of delivering a therapeutic to a target site of a subject comprising administering a lipid capsule to a target site of a subject, wherein the lipid capsule comprises a therapeutic agent; and applying an alternating electric field, at a frequency for a period of time, to the target site of the subject, wherein the alternating electric field releases the therapeutic from lipid capsule at the target site of the subject. Disclosed are methods of increasing target site specific release of a therapeutic agent in a subject comprising administering a lipid capsule to a target site of a subject, wherein the lipid capsule comprises a therapeutic agent; and applying an alternating electric field, at a frequency for a period of time, to the target site of the subject, wherein the alternating electric field releases the therapeutic agent from the lipid capsule at the target site of the subject, thereby increasing the target site specific release of the therapeutic agent. Disclosed are methods of treating comprise administering a lipid capsule to a target site of a subject in need thereof, wherein the lipid capsule comprises a therapeutic agent; and applying an alternating electric field, at a frequency for a period of time, to the target site of the subject in need thereof, wherein the alternating electric field releases the therapeutic agent from the lipid capsule at the target site of the subject in need thereof. Disclosed are methods of killing a cell comprising administering a lipid capsule to a target site, wherein the lipid capsule comprises a therapeutic agent; and applying an alternating electric field for a period of time, to the target site, wherein the alternating electric field releases the therapeutic agent from the lipid capsule at the target site, wherein the target site comprises a cell, wherein the therapeutic kills the cell.

A miniature device is provided for use in a system configured to deliver a therapeutic component to a treatment site in a patient. The miniature device comprises at least one steering portion comprising a magnetic material, and at least one carrier portion affixed to the steering portion and comprising the therapeutic component. The carrier portion is configured to at least partially dissipate under one or more predetermined conditions at the treatment site, thereby releasing the therapeutic component. Further provided is a system comprising one or more such miniature devices and a magnetic inducing apparatus configured to be operated to generate a varying magnetic field, thereby remotely controlling motion of the miniature device.

Embodiments of the present invention are directed to a liquid delivery apparatus. A non-limiting example of the apparatus includes a substrate including a cavity formed in a surface of the substrate. The apparatus can also include a membrane disposed on the surface of the substrate covering an opening of the cavity. The apparatus can also include a hydrophobic layer disposed on the membrane. The apparatus can also include a seal disposed between the membrane and the substrate, wherein the seal surrounds the opening of the cavity. The apparatus can also include an electrode layer coupled to the membrane.

An imaging capsule including, a radiation source, a collimator that provides a collimated beam from the radiation source, at least one detector configured to detect particles resulting from X-ray fluorescence and/or Compton backscattering in response to the collimated beam to reconstruct images of a user's gastrointestinal tract, wherein the imaging capsule is configured to identify an inflamed area, within the user's gastrointestinal tract, based on a count of the detected particles and initiate actions responsive to detecting the inflamed area.

In a medical instrument that is inserted into an affected area or tissue to perform treatment, a technique of delivering various drugs to a target site is desired.

Provided is a medical instrument that is inserted into an affected area or tissue to perform treatment, wherein a drug-loaded nanostructure is covalently bound to the medical instrument via a photosensitive linker immobilized on the surface of at least a portion of the medical instrument.

A composition having nanoparticles having lipids; a polysaccharide coating, an active agent and iron oxide. The active agent can be ciprofloxacin or fluocinolone. A method of treatment of ear disease or ear infection including the administration of a pharmaceutical formulation comprising nanoparticles and magnetically pushing or pulling the nanoparticles to a treatment site.

The present invention relates to ultrasound mediated delivery of therapeutic agents to the pancreas, and particularly for treatment of pancreatic cancer such as pancreatic ductal adenocarcinoma (PDAC). More particularly, the invention provides a cluster composition and a pharmaceutical composition, for use in delivery of therapeutic agents and for treatment of pancreatic cancers, including PDAC.

It is provided a method and device for delivering transdermally a molecule non-invasively to a subject comprising irreversibly electroporating a region of the skin.

A method for directing therapeutic nanoparticle-labeled cells to selected locations within the body and/or for retaining therapeutic nanoparticle-labeled cells at selected locations within the body, the method comprising: providing an article comprising a body of material configured to be secured about the body of a patient and having a plurality of pockets thereon, wherein each pocket is sized to receive and retain one or more magnets therein; injecting therapeutic USPIO nanoparticle-containing cells into a target therapy site; securing the article to the body of the patient; and inserting at least one magnet into at least one pocket so as to provide a desired magnetic field for further directing therapeutic nanoparticle-labelled cells to a target therapy site and/or for retaining therapeutic nanoparticle-labeled cells at the target therapy site.
