MOUTHWASH TO DELIVER DYES FOR DENTAL IMAGING

A mouthwash for fluorescence endoscopic dental imaging includes at least one fluorescent dye and a liquid base. A method for fluorescent endoscopic dental imaging includes orally administering a mouthwash to a subject; waiting a predetermined period of time; removing excess mouthwash from the subject; illuminating the subject with visible or near-infrared light; and capturing fluorescent light from the subject to create an image.

Indirect chromoendoscopy with an oral indigo carmine base preparation
11160882 · 2021-11-02 ·

Indirect chromoendoscopy is performed by providing a subject with an orally administered composition which includes indigo carmine dye mixed with polyethylene glycol (PEG). Preferably, the subject ingests at least 160 mg of indigo carmine prior to the endoscopic procedure. This is accomplished by ingesting 1 ml to 6 L of a premixed or reconstituted indigo carmine and PEG composition up to twenty four hours prior to the endoscopic procedure.

FLUORESCEIN FORMULATIONS AND KITS
20230277693 · 2023-09-07 ·

Compositions comprising a fluorescein component and benoxinate component and the corresponding uses of these compositions are described herein. These compositions have improved storage life and the fluorescein component and/or benoxinate component minimally degrade after 12 to 18 months of storage.

TOPICAL APPLICATION OF NERVE LABELING DYES FOR IMAGE-GUIDED SURGERY

The present invention relates to a topical agent that binds specifically to myelin basic protein and its method of use and determining myelination in the subject by detecting the agent present in the subject. A kit containing the agent or its derivatives for use in detecting myelin basic protein is also provided.

SOLUTION COMPRISING FLUORESCENT DYE AS FIDUCIAL MARKER

The present disclosure relates to a solution comprising a water insoluble carbohydrate and a fluorescent dye, such as a near infrared (NIR) contrast agent, wherein the solution sets under aqueous conditions, such as in vivo, to form e.g. a gel, a glass, a semi-solid, a solid, a crystal or any mixtures thereof. The disclosure further relates to preparation of such solution and use of such solution for in vivo imaging and/or guidance of surgery or interventional therapeutic procedures.

LIQUID DELIVERY COMPOSITION

The invention provides a composition for use as a delivery vehicle comprising at least one thermo-responsive polymer (polymer A) and at least one ion-sensitive polymer (polymer B) in a liquid formulation. Polymer A is preferably a polyoxyethylene-polyoxypropylene block copolymer or a cellulose derivative. Polymer B a polysaccharide. The composition can include an active substance for delivery or can be used as a delivery vehicle for a substance added at the time of administration such as mesenchymal stem cells.

Corneal marking ink
11000343 · 2021-05-11 · ·

The present disclosure relates generally to dry inks for use in marking the eye prior to surgery and methods of applying the same to eye marking devices. Such inks can include various accepted inks for use on the eye that can be applied to a marking device using relatively fast-evaporating solvents. In this manner, the remaining ink composition can be precisely placed on the eye marking device, and desirably transfer to the marking surface of the eye without dissolving on the journey through the various membranes above the marking surface. Application methods may include use of charged ink particles that may be advantageously manipulated using magnetic fields to even more precisely place the dry ink on a marking device.

Compositions and methods for detecting cancer cells in a tissue sample

This invention is directed to methods for the facile and accurate identification of cancer cells in a tissue sample, such as a surgical field. In particular, the compositions and methods employ conjugates comprising pro-fluorescent fluorescein based moieties bound to folic or pteroic acid targeting moiety optionally through a linker. The pro-fluorescent fluorescein based moieties are non-fluorescent but capable of being rendered fluorescent by intracellular processes. The conjugates are employed to detect cancer cells that overexpress folic acid receptors thereby providing for differential accumulation of these conjugates in these cells.
