Therapeutic fluid delivery cartridge
An external medical device includes a first cartridge bay with a first cartridge port, a second cartridge bay with a second cartridge port, a fluid outlet in fluid communication with the first cartridge port, a fluid pump configured to deliver a therapeutic fluid from a fluid cartridge engaged with the first cartridge port through the fluid outlet in response to fluid outlet control signals, a fluid inlet in fluid communication with the second cartridge port, and a fluid control structure in fluid communication with the fluid inlet to control fluid flow through the fluid inlet.
System and method for obtaining a cellular sample enriched with defined cells such as platelet rich plasma (PRP)
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 and apparatus for delivery of cell therapies
A method and apparatus for delivery of cell therapies, introduced via percutaneous access to the circulation, and delivered to the site of vascular injury intervention.
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.
System for multi-processing and separation of biological fluids
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 control 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.
A Bioprocessing System
Disclosed is a bioprocessing system comprising apparatus (200) including a centrifugal separation housing (210) having a temperature controllable compartment (215) for removably accepting a separation chamber (50), the apparatus further comprising at least one mixing station (250) for supporting one or more fluid storage vessels (10, 20, 30, 40), the station including a temperature controllable area (252) for increasing or decreasing the temperature of the contents of the or each supported vessel. The system further includes a disposable fluidic arrangement (100) including a centrifugal separation chamber (50) removably mountable within the compartment (215) and having one or more ports (52) allowing fluid ingress into, or egress out of the chamber, via the one or more ports in use, said ports being in fluid communication with one or more of said fluid storage vessels via fluid conduits (12, 22, 32, 42) and via one or more valve arrangements
POSITIVE PRESSURE INSPIRATION DEVICE FOR DELIVERY OF MEDICAMENTS
A respiratory system includes a nebulizer pneumatically connected to a breathing unit. A pressure sensitive mechanism detects negative pressure at the breathing unit due to inspiration and initiates nebulization. The nebulizer is configured to cease nebulization prior to the end of inspiration. Residual medicament disposed in the system is cleared from the system and delivered to the patient during the remainder of the inspiration cycle. A compressor provides positive pressure to aid delivery of medicaments to the patient.
METHODS AND COMPOSITIONS FOR NON-CYTOTOXIC STEM CELL TRANSPLANTATION
Certain embodiments are directed to compositions and methods for non-cytotoxic hematopoietic stem cell transplantation.
Collection Of Mononuclear Cells And Peripheral Blood Stem Cells
Blood in a separation chamber is separated into a red blood cell layer, a plasma constituent, and a mononuclear cell-containing layer. A portion of the plasma constituent exits the chamber via a plasma outlet, while a first portion of the red blood cell layer exits via a red blood cell outlet. A second portion of the red blood cell layer exits the chamber via the red blood cell outlet and is collected. At least a portion of the collected red blood cell layer may then be conveyed to the chamber via the red blood cell outlet to convey at least a portion of the mononuclear cell-containing layer out of the chamber via the plasma outlet for collection. A second portion of the plasma constituent may be conveyed out of the chamber via the plasma outlet to more fully collect the mononuclear cell-containing layer without the use of collected plasma.
APPARATUS AND METHOD FOR ISOLATING STEM CELLS
An apparatus for isolating stems cells from extracted mammalian tissue comprising: a portable hollow casing having fixed dimensions and a sized internal spatial volume; a filter housed and contained within said sized internal spatial volume, wherein said filter captures particles in said extracted mammalian tissue having a diameter of about 5 to 10 microns or more and allows particles in said extracted mammalian tissue having a diameter of less than about 5 to 10 microns to pass through; a first channel to which a container holding said extracted mammalian tissue can attach, and through which said extracted mammalian tissue is input into the hollow casing; wherein a stem cell collection chamber can attach to said first channel, and the particles having a diameter of about 5 to 10 microns or more are output from the hollow casing through said first channel and collected in the stem cell collection chamber; and a second channel to which a remnant collection chamber can attach, and through which the particles having a diameter of less than about 5 to 10 microns are output from the hollow casing and collected in the remnant collection chamber.
