Sealant injection systems for injecting sealant into a cavity, the sealant injection systems including a sealant dispensing tip having a proximal end portion, a body portion, and a distal end portion that define a continuous channel to an aperture in the distal end portion for dispensing sealant material into a cavity, where the aperture is surrounded by a compressible material. The distal end portion may have a linear ridge defined on an end face, the aperture being asymmetrically provided relative to the ridge.

This invention relates to an apparatus for dispensing a viscous fluid whether in combination, disassembly or assembly. The apparatus comprising a cartridge, reservoir or tube containing the fluid and having an openable or opened outlet structure which, when opened, allows the expression of the fluid from a created outlet aperture. A nozzle is engaged or engageable to the outlet structure and/or cartridge, reservoir or tube whereby fluid expressed from the outlet aperture can subsequently move to and be expressed from the nozzle outlet. The openable or opened outlet structure is adapted to provide on opening at least one outlet aperture having a size of area A; and wherein the nozzle has or is adapted to be cut to provide a nozzle outlet of area B, area B being greater than or equal to area A.

Devices and methods for sealing staples in tissue using a plurality of adjunct segments are described herein. In one embodiment, an end effector for a surgical instrument is described that can include first and second jaws, where the first jaw has a cartridge body removably attached thereto and the cartridge body has a plurality of staple cavities configured to seat staples therein. The second jaw can have an anvil with a plurality of staple forming openings formed therein, and at least one of the first and second jaws can be movable relative to the other jaw. The end effector can also include a plurality of sealing adjunct segments coupled to one another and at least one of the first and second jaws such that a staple ejected from the cartridge body passes through one of the plurality of sealing adjunct segments and tissue disposed between the first and second jaws.

A dispense tip constructed and arranged to communicate with a material dispensing pump comprises an elongated neck and a molded base having a first portion and a second portion opposite the first portion. The neck extends from the first portion of the base. The second portion is constructed and arranged to abut an outlet surface of the pump. An outermost region of the second portion of the base includes a compressible fluid-tight surface that compliantly conforms to the outlet surface when the dispense tip is mounted to the pump.

A portable electric (battery) powered paint system designed to worn in a typical workman's tool belt and thus accompany the painter as he moves from wall to wall and room to room without the restriction of electrical cords plugged into wall outlets. The invention consists of a paint reservoir, an electric paint pump, a power pack of two or more 18 Volt batteries, a paint applicator and associated paint supply tubing for transfer of paint from the reservoir to the paint applicator. The invention provides the painter with a self-contained powered painting system.

A nozzle for applying a fluid material to an object includes a tubular wall with several circumferentially spaced ribs that extend outward from the tubular wall to engage an object to which the fluid material is to be applied. The ribs space the tubular wall from the inner wall to provide a gap for the fluid material and aligning the tubular wall with the hole in the object. The tubular wall provides at least one opening between adjacent pairs of ribs for the fluid material to flow into the gap. A sealing surface on the nozzle engages a portion of the object preventing escape of the fluid from the gap. In a process for using the nozzle, a user manually detects equilibrium between the pressure applied to the fluid in the nozzle and the pressure in the nozzle to determine when the gap has been filled.

Devices and methods for applying sealants to surgical instruments. In one embodiment, a surgical device is described that can include at least one nozzle formed at a proximal end of the device that is configured to receive a sealant, as well as an applicator formed at a distal end of the device that is configured to deliver the sealant received by the at least one nozzle. The applicator can be configured to interface with at least one of a first and second jaw of a surgical stapler such that the sealant delivered from the applicator can be deposited into a plurality of openings formed in the surgical stapler.

Devices and methods for forming an anastomosis between two body lumens are described herein. In one embodiment, an anastomosis can be formed by transecting a body lumen using a linear surgical stapler that delivers a plurality of sealing adjuncts in combination with a plurality of surgical staples along a staple line, where the plurality of sealing adjuncts are coupled to one another by a suture. A circular surgical stapler can be used to create an anastomosis with a second body lumen across the staple line. Before actuating the circular stapler, the proximal and distal ends of the staple line can be drawn into a central lumen of the circular stapler using the suture extending between the plurality of sealing adjuncts such that the staple line is resected when the circular stapler is actuated.

A paste application device stores two starting components, for mixing the starting components to form a paste and for the application of the paste. The comprises a two-component cartridge comprising two cylindrical internal spaces, two feed plungers that can be shifted axially in the internal spaces and limit the internal spaces on a first side of the two-component cartridge, and at least two dispensing openings by means of which the internal spaces are open on a second side of the two-component cartridge that is opposite from the first side, a hollow cylinder that is made of a plastic material and has one front face that is open and one front face that is partially closed, in which is situated an axially mobile plunger that has two pestles attached to it, whereby the pestles are oriented in the direction of the open front face, whereby the open front face of the hollow cylinder is arranged to axially touch against the first side of the two-component cartridge, and whereby the plunger closes in gas-tight manner against the internal walls of the hollow cylinder, whereby the two-component cartridge and the hollow cylinder are arranged in a pressure vessel, whereby the pressure vessel touches against the hollow cylinder or is situated at a distance from the hollow cylinder of at most 0.1 mm.

A liquid sealant applicator system that may include a liquid sealant applicator having a coupling to reversibly connect to a source of liquid sealant, a sidewall extending from the coupling and defining a sealant flow path, a flow restrictor that restricts the sealant flow path to an annular pattern of apertures in the flow restrictor, a porous matrix that fills at least a portion of the sealant flow path downstream of the flow restrictor, a matrix retainer configured to retain the porous matrix within the sealant flow path, and a fastener socket connected to the sidewall and having a distal end configured to be placed over and at least substantially enclose the head of a preselected fastener. The applicator is configured to provide a uniform application of sealant from the source of the liquid sealant to the head of the fastener enclosed by the fastener socket.
