TISSUE COLLECTION AND DELIVERY DEVICE AND METHODS OF USE THEREOF

A system and method for harvesting autologous tissue, mincing it into fragments that are visible and measureable when filtered, and delivering a portion of the tissue back into the patient without the need to directly touch the tissue. During the same surgical procedure, the tissue can be mixed with a biocompatible agent before introduction into the repair site.

Conditioning harvested fat for re-injection

A fat conditioning apparatus includes a conditioning vessel enclosing a conditioning chamber and a displacable plug. The conditioning chamber is bounded on one end by the displacable plug and has a variable volume that is a function of the position of the plug within the conditioning vessel. The apparatus has utility in a fat conditioning method, wherein the conditioning chamber contains a harvested fat emulsion. A washing liquid is injected into the conditioning chamber and mixes with the harvested fat emulsion, thereby displacing the plug in an outward expansion direction and expanding the variable volume of the conditioning chamber. The resulting mixture of harvested fat emulsion and washing liquid is stratified in the conditioning chamber into a contaminant-lean fat fraction and a contaminant-rich remainder fraction. The fat fraction, which is substantially free of the remainder fraction, is recovered from the conditioning chamber as a desired product of the method.

Liquid drug-filtering filter medium and filter module
10695486 · 2020-06-30 · ·

A liquid drug-filtering filter medium is provided, which can include a nanofiber web having a three-dimensional network structure for filtering foreign substances included in a liquid drug. According to the embodiment, the occurrence of differential pressure when drawing in and filtering a liquid drug is minimized, and thus the liquid drug may be quickly drawn into a syringe cylinder within a short time and by applying small force, and at the same time, the filtration rate of foreign substances in the liquid drug is very outstanding. A method for producing the liquid drug-filtering filter medium is also provided, which enables the very easy adjustment of a pore structure of the filter medium or the diameters of the pores in order to enable the pore structure to minimize the occurrence of differential pressure or change the differential pressure to a target level.

SELF-PUNCTURING LIQUID DRUG CARTRIDGES AND ASSOCIATED DISPENSER
20200197631 · 2020-06-25 ·

Self-puncturing liquid drug cartridges and an associated inhaler are used to deliver one or more separate doses of an aerosolized liquid drug. A cartridge includes a needle assembly coupled to a drug container. The needle assembly includes a hollow needle and is reconfigurable from a first configuration to a second configuration upon insertion of the cartridge into the inhaler. In the first configuration, the hollow needle does not extend into the container. In the second configuration, the hollow needle extends into the container. The inhaler includes an aerosol generator that includes a vibratable membrane that aerosolizes liquid drug ejected from the cartridge for inhalation by a patient.

DISPOSABLE SYRINGE FOR USE WITH PNEUMATIC DRIVERS
20200197620 · 2020-06-25 ·

A disposable syringe for use with a pneumatic driver. The syringe has an elongated barrel with a cap secured to the proximal end that has a through bore. A filter is secured to the cap interior of the barrel that covers an opening in the through bore interior of the barrel. The pneumatic driver includes a source of pressurized air; a support for receiving and locating the syringe; and a supply block configured to receive pressurized air from the source and having an outlet for delivery of pressurized air. The supply block is movable between a first position spaced apart from the cap of the syringe and a second position in contact with the cap with fluid communication being established between the outlet of the supply block and the through-bore in the cap.

FILTER FOR REDUCING PHENOLIC COMPOUNDS FROM INSULIN AND RELATED INFUSION AND INJECTION DEVICES

Provided herein are devices, systems, and methods for the removal of preservatives/excipients/stabilizers from pharmaceutical preparations/medicaments. The devices and systems include a resin for the filtering of preservatives from pharmaceutical preparations. The methods allow for a period of time of incubation of the pharmaceutical preparation in the resin that effectively removes preservatives, while at the same time maintaining the required amount or concentration of active compound in the preparation. Also provided herein are devices, systems, and methods for the controlled release of anti-inflammatory agents in an insulin infusion set.

Medical Syringe System with Filtered Filling Port

A syringe system includes a syringe and a filtration device connected to the syringe for sterilizing and introducing fluid into the syringe. The syringe includes a syringe barrel having a proximal end defining a barrel opening, a distal end defining a delivery opening, a bore extending between the proximal end and the distal end, and a stopper disposed in the bore of the syringe barrel. The filtration device has an inlet and an outlet coupled in fluid communication with the delivery opening at the distal end of the syringe barrel. The filtration device includes a stem and a filter membrane disposed in line with the stem. The filter membrane optionally has a plurality of pores each with a nominal pore size in a range of approximately 0.1 m to approximately 0.5 m such that a pharmaceutical fluid can be introduced as a sterilized pharmaceutical fluid into the bore of the syringe barrel by passing through the filtration device.
