A method of sealing a resected surface of an organ includes applying a synthetic matrix to a resected surface of an organ, and applying an adhesive on the synthetic matrix so that the adhesive penetrates through interstices of the synthetic matrix for contacting an interface between the synthetic matrix and the resected surface of the organ. The method includes curing the adhesive for bonding the synthetic matrix to the resected surface of the organ. The synthetic matrix is a non-woven mesh made of polyglactin 910 or any other synthetic or non-synthetic fabric having a similar porosity or density. The adhesive is a biosynthetic or a synthetic adhesive. After penetrating through the pores of the synthetic matrix and curing, the cured biosynthetic or synthetic adhesive mechanically interlocks with the synthetic matrix for adhering the synthetic matrix to the tissue for creating a sealing barrier.

An aerosol spray device includes a container having first and second fluid reservoirs disposed therein that are divided from one another. The first fluid reservoir holds a first mixture including a first aerosol propellant and a first part of a silicone based topical skin adhesive that is dissolved in the first aerosol propellant. The second fluid reservoir holds a second mixture including a second aerosol propellant and a second part of the silicone based topical skin adhesive that is dissolved in the second aerosol propellant. An aerosol spray dispensing system is connected with the container, which is configured to combine the first and second mixtures to form the silicone based topical skin adhesive and dispense the silicone based topical skin adhesive from the container as an aerosol spray.

A system for dispensing a curable composition includes a dual barrel syringe including a first syringe barrel with a first plunger, and a second syringe barrel with a second plunger. A static mixer is connected with distal ends of the first and second syringe barrels. The first and second plungers are moveable toward the distal ends of the first and second syringe barrels for expelling first and second components of a curable composition from the distal ends of the barrels into the static mixer for mixing the components to form the curable composition. A flexible spreader connected with a distal end of the static mixer has a flat dispensing opening, and a plurality of channels extending to the flat dispensing opening to dispense the curable composition. A hot gas blower generates a hot gas stream flowing distally over the distal end of the flexible spreader for curing the curable composition.

The invention relates to methods of treating baldness, treating alopecia, promoting hair growth, and/or promoting hair follicle development and/or activation or stimulation on an area of the skin of a subject (for example, a human) by subjecting said area of the skin to integumental perturbation. Integumental perturbation can be used in combination with other treatments for promoting hair growth. The invention provides devices for integumental perturbation for promoting hair growth, and provides pharmaceutical compositions for use in combination with integumental perturbation for promoting hair growth.

A co-reactive liquids delivery applicator, including first and second hollow cylindrical cartridges, each including a stopper at a proximal end and a sealing septum on a distal end and the cartridges containing co-reactive liquids therein, an applicator body including two adjacent chambers configured to secure the first and second cylindrical cartridges, a manifold positioned at a distal portion of the applicator body, the manifold including a pair of hollow needles extending from a proximal portion and a tip connection positioned at a distal portion thereof, and a toggle configured to advance the manifold towards the distal end of the cartridge, wherein upon advancing the manifold each hollow needle penetrates the sealing septum and establishes fluid communication with one of the liquids of the first and second cylindrical cartridges.

Devices and methods are described for occluding the left atrial appendage (LAA) to exclude the LAA from blood flow to prevent blood from clotting within the LAA and subsequently embolizing, particularly in patients with atrial fibrillation. An implant is delivered via transcatheter delivery into the LAA. The implant includes a conformable structure comprising a foam body and internal support. The support includes anchors that penetrate the foam body and anchor the implant to the walls of the LAA. The implant provides compliance such that it conforms to the native configuration of the LAA.

A spray device includes a first spray tip having a first fluid pathway defining a first flow area, and a second spray tip includes a second fluid pathway that defines a second flow area that is larger than the first flow area of the first spray tip. The first and second spray tips are side-by-side and spaced from one another at a distal end of the spray device. When a first fluid having a volumetric flow rate is introduced into the first spray tip and a second fluid having the same volumetric flow rate is introduced into the second spray tip, the first fluid will flow through the first fluid pathway at a greater velocity than the second fluid will flow through the second fluid pathway.

An assembly for mixing and dispensing a multi-component fluid includes a sheath having first and second fluid chambers, a chamber coupler, and a flexible tip. The chamber coupler forms first and second fluid channels. Additionally, the flexible tip forms a mixing chamber with a variable mixing volume and an outlet. The flexible tip is coupled to the chamber coupler near a distal end of the sheath. In the presence of an activation force, the flexible tip is forced out of the sheath and positioned in a dispensing state with a maximum mixing volume. In the absence of the activation force, the flexible tip is housed within the sheath and positioned in a non-dispensing state with a minimum mixing volume such that the outlet is substantially closed.

A mixing injector for a multi-material printer. The injector defines coaxial passages for passing different material components into a mixing portion. The injector defines at least one opening, in a sidewall of at least one of the coaxial passages, to provide fluid communication between the passages, e.g., before/upstream from a mixing portion. Such openings permit and promote material component flow laterally, transversely to a direction of elongation of the coaxial passages, and transversely to a principal direction of flow of the material components. This is believed to create a degree of turbulence in the flow of the material components that enhances mixing of the material components, and provides for enhanced mixing of the component materials. Accordingly, for example, cross-linking may begin to occur before entering the mixing region. The injector may be structured to provide any desired number of passages and openings to provide a desired degree of mixing.

The present invention relates to a dispensing system (1) having at least two chambers (2,3) for a tissue adhesive system comprising at least two components, wherein first chamber (2) is designed as a hollow cylinder (H), which has a closed design on an end face (2a) and an open design on its opposite end face (2b) and second chamber (3) in a solid cylinder (V) is designed as an annular gap (4) and annular gap (4) extends from an end face (3a) facing hollow cylinder (H) to a mixing chamber (5) arranged on opposite end (3b) of solid cylinder (V) and hollow cylinder (H) is arranged on the side of its open end face (2b) in annular gap (4) of solid cylinder (V) so it can move in longitudinal direction (L), wherein at least one feed duct (6) is designed in solid cylinder (V), which extends on the inside of annular gap (4) from end face (3a) of solid cylinder (V) facing hollow cylinder (H) to mixing chamber (5), wherein a mixing tube (7) is provisioned in mixing chamber (5), which projects laterally from solid cylinder (V) and is arranged so it can move essentially transversely to the longitudinal expansion of solid cylinder (V) and closes the inside of mixing tube (7) off from feed duct (6) and annular gap (4) in a first position and unblocks it in a second position. The invention also relates to a kit consisting of a dispensing system, which is filled with tissue adhesive system comprising at least two components as well as a method for closing a wound using said kit.
