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.

A medical liquid injection device includes a base body, a needle assembly mounted on the base body, a reservoir fluidly connected to the needle assembly and having a plunger therein, a driving unit that linearly moves the plunger, and an encoder unit disposed at an end of the driving unit to measure rotation of the driving unit.

Provided are a sliding elastic body capable of imparting excellent sliding properties and resistance to protein adsorption and, at the same time, maintaining sealing properties; and a syringe gasket, a catheter, and a tire which include the sliding elastic body. The present invention relates to a sliding elastic body including an elastic body whose surface is fully or partially laminated with a fluororesin film, the laminated elastic body being treated with a fluorinated oil.

A dispenser assembly is provided that has a rigid plunger with a ring-shaped protrusion. The protrusion contacts the inner wall of a flexible barrel to form a liquid-tight seal. Advantageously, the dispenser assembly does not require additional components, such as o-rings, and can be fabricated by injection molding techniques.

Ambulatory infusion pumps, medicament reservoirs, and plungers, including both dynamic and static seals, plus related components, as well as component combinations and related methods.

An antiseptic medical cap that may include a base, a sidewall, and a chamber configured to receive a proximal end of a medical fluid port having an opening. The antiseptic medical cap, in some instances, may include an insert having a gas-releasing anti-microbial compound and/or include a nitric oxide-releasing system that is configured to be positioned at least partially through the opening of the medical fluid port when the antiseptic medical cap receives the proximal end of the medical fluid port into the chamber.

Embodiments of a syringe-based device for delivering fluid include a housing, a port, the port being positioned at about the distal end of the housing, a plunger assembly, the plunger assembly including, a plunger seal, a valve, and a cannula, a first fluid reservoir, where the first fluid reservoir retains a first type of fluid, a syringe including a syringe body, a syringe port, a plunger, and a second fluid reservoir, the second fluid retaining a second type of fluid, and where the syringe transitions from a first configuration in which a first portion of the first fluid type is delivered through the port, to a second configuration in which the second type of fluid in the second fluid reservoir is delivered through the port, to a third configuration in which a second portion of the first fluid type is delivered through the port.

A syringe for use with a medical injector system includes a barrel and a semi-rigid hub, the hub having an outer surface adapted to slidingly move within the barrel, and an inner surface having a continous circumferential wall. The hub further includes an annular engaging portion recessed within at least part of the continous circumferential wall forming a groove, at least one radially extendable and retractable retention member disposed at partially within a proximal cylindrical portion of the hub, and the elastometric seal engaged with a seal engaging portion on the hub and slidingly engaged with the barrel of the syringe. The semi-rigid hub and the elastomeric seal are reciprocally slidable within the barrel, and the at least one radially entendable and retractable retention member is configured to releasably engage the groove upon retraction of the plunger to permit the semi-rigid hub to be selectively withdrawn within the barrel.

The disclosure relates to a medicament delivery device, comprising a medicament cartridge adapted to contain a medicament and a stopper slidably arranged within the cartridge. The stopper-comprises a rigid body that is enclosed partially by a soft sealing component.

A syringe assembly including: (1) a syringe barrel defining a chamber; (2) a plunger mounted in the chamber and moveable with respect to the barrel; and (3) a cap holder assembly containing a cap and an absorbent material removably attached to the syringe.
