CRYOTHERAPEUTIC DELIVERY DEVICE

A device for aseptic delivery of biological material from a vial includes a tubular barrel, a filter assembly, and a dispersion funnel assembly. The tubular barrel includes a receiving end to accept at least a portion of the vial within the tubular barrel, and a dispensing end opposite the receiving end. The filter assembly is fluidly connected to the dispensing end of the tubular barrel. The dispersion funnel assembly is configured to connect to the vial, and to be disposed at least partially within the tubular barrel. The dispersion funnel assembly has an open configuration to disperse the biological material from the vial into the tubular barrel between the dispersion funnel assembly and the filter assembly, and a closed configuration to force the dispersed biological material through the filter assembly when the dispersion funnel assembly is moved toward the dispensing end of the tubular barrel.

Therapeutic agent delivery system and method for arteries

A delivery system for delivery of a therapeutic agent such as stem cells into a vein and across a micro circulation system into an artery comprises a multi lumen catheter for delivery of a therapeutic agent. A discharge device is located in a vein. The operation of the delivery device is controlled by a pressure stem cell solution delivery gun system. There are multiple delivery stages. These may include delivery of an elixir to open up the pressure bed, a platelet-rich plasma, stem cells, scaffolds, and finally an elixir to provide emichment and nourishment of the stem cells.

AEROSILIZATION OF STEM CELLS OR STEM CELL DERIVATIVES FOR PULMONARY DELIVERY

A treatment system delivers a breathing gas and frozen stem cells or other biologic particles (FBP) to a bronchus of a lung of a patient in order to treat lung and other conditions. The breathing gas and the FBP are usually delivered through separate lumens. The FBP may be delivered concurrently with other frozen particles, such as frozen saline particles (FSP). The FBP/FSP will remain frozen at all times from preparation to delivery, and will thaw only after they are released into the lung.

The present invention relates to a component separator capable of guaranteeing the purity of a subject component such as isolated blood or stem cells while simplifying a process compared with a conventional technique, and preventing air contamination during a component separation process, the component separator comprising: a hollow main body having a communication pipe, through which a body fluid communicates, formed at one end portion, and a main body female screw part disposed at the other end portion; a plunger for varying a main body space while moving forward and backward inside the main body; and an operation member having a pressing tube having a pressing male screw part capable of being screwed with the main body female screw part, and a plunger coupling tube having a tube screw screwed with a plunger screw part at the lower part of the plunger by coming into contact with or retracting from the inside of the pressing tube.

Targeted delivery of magnetically tagged active agents in combination with negative pressure wound therapy

Methods and systems for treating a wound using targeted delivery of magnetically-tagged active agents in combination with negative pressure wound therapy are presented. In particular, a magnetically-active wound insert may be used to attract magnetically-tagged stem cells to a wound site to treat the wound.

SYSTEM AND METHOD FOR OBTAINING A CELLULAR SAMPLE ENRICHED WITH DEFINED CELLS SUCH AS PLATELET RICH PLASMA (PRP)
20180221561 · 2018-08-09 · ·

A system for obtaining plasma enriched in platelets is disclosed which is closed to the atmosphere. The system includes: a collection tube containing an anticoagulant portion and a separation gel; a first collection syringe adapted to collect a portion of fluid relatively depleted in platelets from said collection tube after centrifugation; and a second collection syringe adapted to collect plasma enriched in platelets from said collection tube after centrifugation, said second collection syringe further comprising a filter unit adapted to filter cells included in said plasma enriched in platelets.

METHOD FOR OBTAINING STERILE HUMAN AMNIOTIC FLUID AND USES THEREOF
20180142204 · 2018-05-24 ·

Provided herein is a pre-Caesarean method for collecting amniotic fluid from a patient. A needle is inserted into the incision site for the future C-section, which may be under ultrasound guidance, through which the amniotic fluid is drawn under a low level suction and, optionally, gravity to a sterile collection container. The method encompasses filtering and/or irradiating the amniotic fluid to collect biomolecules of interest such as growth factors and/or stem cells. Also provided is the sterile amniotic fluid or filtrates thereof collected by the method described herein

Systems And Methods For Shockwave Mediated Delivery Of Microvesicles And Stem Cells
20240358983 · 2024-10-31 ·

Methods, systems, and devices are disclosed for facilitating delivery of microvesicles or stem cells across the blood brain barrier (BBB). A pressure device is used to target a region of a patient's brain. The pressure device delivers a shockwave to the targeted region, facilitating delivery of a microvesicle or stem cell at the targeted region. The shockwave does not damage brain tissue and does not disrupt or tear the BBB. A microvesicle or stem cell, or both, is administered to the patient and crosses the BBB at the targeted region, without damaging, tearing, or disrupting the BBB.

System and method for obtaining a cellular sample enriched with defined cells such as platelet rich plasma (PRP)
09962480 · 2018-05-08 · ·

The invention relates to a system and method for obtaining a cellular fraction enriched with defined cells effective in promoting a defined cellular response from an in vivo cellular sample. The system is closable to the atmosphere, and includes a cell suspension collection tube containing gel and anticoagulant, adapted such that, when containing cell suspension and centrifuged after treatment the collection tube yields separation fractions, a first fraction comprising cellular fluid, a second fraction comprising gel layer, a third fraction comprising enriched cellular portion on top of the gel layer and a fourth fraction comprising a cell poor portion. The cell poor portion may be extracted and discarded prior to extracting the enriched cellular portion.

SYSTEM FOR MULTI-PROCESSING AND SEPARATION OF BIOLOGICAL FLUIDS
20180111132 · 2018-04-26 · ·

A system for the processing and separation of biological fluids into components comprises an apparatus that cooperates with a disposable set, comprising a cabinet (100) for housing a hollow centrifugal processing chamber (20) of the disposable set. The cabinet comprises a plurality of side-by-side locations (110) for receiving a corresponding plurality of centrifugal processing chambers (20) in side-by-side spaced-apart relation. Each location comprises an individual drive means (52) for driving its centrifugal processing chamber. Remotely-actuable valves (124) associated with the disposable sets are located on the apparatus' cabinet in the proximity of said locations. Valve actuation provides a display of the state of actuation of the valves (124). Selection of this state of actuation is arranged to control connection of the centrifugal processing chamber (20) of each fitted disposable set with a flexible container (200) of the same disposable set or another container, and to contol connection of the centrifugal processing chambers (20) with flexible containers of the same or other fitted disposable sets in different combinations, in particular with series and/or parallel connections.
