Pixel array medical systems, devices and methods
A system comprising a handpiece and drive system configured to removably couple to a proximal end of a housing. A scalpet assembly is configured to removeably couple to the housing, and includes a scalpet array comprising at least one scalpet configured for rotation. The scalpet array is configured to harvest dermal plugs via fractional resection. A collection chamber is configured to collect the dermal plugs, and to house formation of an injectable filler by mincing the dermal plugs, and mixing the dermal plugs with a carrier. The injectable filler is configured for bulk fill. The collection chamber includes a loading port, and a cannular syringe is configured to mate with the loading port to receive the injectable filler, and to deliver the injectable filler for the bulk fill.
3-DIMENSIONAL LARGE CAPACITY CELL ENCAPSULATION DEVICE ASSEMBLY
Disclosed herein are implantable 3-dimensional large capacity device assemblies, specifically, large capacity device assemblies for encapsulating pancreatic progenitor cells for treatment of diabetes.
POROUS MEMBRANE STRUCTURES AND RELATED TECHNIQUES
A conductive porous fabric can be formed, such as by using a template material. The porous fabric can be conductive, such as thick enough to be self-supporting, or supported such as by another structure. The porous fabric can be used in implantable or percutaneous applications, such as to provide an immunoisolation barrier. In another example, the fabric can be coupled to an electric potential, such as to facilitate gas evolution when the porous fabric is located in an aqueous medium. Such gas evolution can be used for various purposes, such as to maintain living cell viability by providing oxygen, or for self-cleaning. Illustrative examples of porous fabric materials include gold, platinum, palladium, iridium, niobium, or a form of carbon such as graphene.
Bioartificial Ultrafiltration Device and Methods Related Thereto
Bioartificial ultrafiltration devices comprising a scaffold comprising a population of cells enclosed in a matrix and disposed adjacent a plurality of channels are provided. The population of cells provides molecules such as therapeutic molecules to a subject in need thereof and is supported by the nutrients filtered in an ultrafiltrate from the blood of the subject. The plurality of channels in the scaffold facilitate the transportation of the ultrafiltrate and exchange of molecules between the ultrafiltrate and the population of cells.
Multi-component injection system and methods for tissue repair
The present disclosure provides devices, kits and methods for preparing injections with cells and carrier components for delivery to a target area in the body. The disclosed devices, kits, and methods provide preparation and monitoring of injections.
INJECTION DEVICES
The invention relates to an injection device which includes a handle and a guard which together enclose a movable cartridge which can contain liquid material to be injected, and further enclose a movable injector that includes a needle, the needle being attached to a housing where the housing is attached to the cartridge, the device also including a delivery mechanism whereby the needle is moved from a retracted to an extended position, and independently the volume of the chamber may be adjusted to expel the contents thereof through the needle and into a subject in need thereof. The injection device may be communicatively connected to a control unit so as to provide a dermal injection system.
SKIN TREATMENT SYSTEM
A skin regeneration therapy combining precise bioelectric signals, light, and biologics for skin treatment and regeneration. Precise bioelectric signals give clear instructions to the stimulated cell DNA/RNA to produce specific regenerative proteins on demand. Bioelectric signals give clear instructions to cell membranes on what to let in and what to let out and serve as an equivalent or surrogate of environmental stimuli to cause a cell action in response.
Magnetic Delivery System and Hydrogel Fixative for Therapeutic Cells
A method of delivering cells to a target tissue is provided comprising depositing a hydrogel pre-gel comprising magnetic particle-loaded cells to the target tissue and, prior to or during gelation of the hydrogel, drawing the magnetic particle-loaded cells to the tissue with a magnetic field, followed by gelation of the hydrogel to lock the cells in place on the tissue. The cells may be mesenchymal stem cells, such as adipose-derived mesenchymal stem cells, and the target tissue may be adventitial tissue of an aneurysm in a blood vessel. Also provided are devices useful in the method.
Large Capacity Manifold For A Medical/Surgical Waste Collection System
A manifold for a medical/surgical waste collection system. An outlet opening and a fitting are in fluid communication with a manifold volume within a housing. The fitting receives a suction line. A filter element with porous features is disposed within the housing such that a fluid communication path is established across the filter element. The porous features trap material entrained within the fluid. A material collection volume is at least partially distal to and below a bottom of the filter element. As the fluid and the material is drawn through the fluid communication path, the material collects within the material collection volume. A flow diverter may be positioned within the housing for directing the material towards the material collection volume. The material collection volume may be at least partially defined by a tissue trap removably coupled to the housing.
FRONT-LOADABLE FLUID TRANSFER ASSEMBLIES AND RELATED MEDICAL FLUID TRANSFER SYSTEMS AND METHODS
Devices for transferring fluid to or from a subject include a plunger assembly coupled to or coupleable to a cannula assembly to allow target fluid to be “front-loaded” into a distal end of the cannula assembly while the stylet is withdrawn a distance to create a vacuum and define a flow channel.
