Disclosed is a method of manufacturing a nano metal wire, including: putting a metal precursor solution in a core pipe of a needle; putting a polymer solution in a shell pipe of the needle, wherein the shell pipe surrounds the core pipe; applying a voltage to the needle while simultaneously jetting the metal precursor solution and the polymer solution to form a nano line on a collector, wherein the nano line includes a metal precursor wire surrounded by a polymer tube; chemically reducing the metal precursor wire of the nano line to form a nano line of metal wire surrounded by the polymer tube; and washing out the polymer tube by a solvent.

High strength or load bearing nylon fiber with break tenacity greater than 7.5 g/den and/or a tenacity at 10% elongation of greater than 4.0 g/den as well as yarns, fabrics and articles of manufacture thereof and methods for their production are provided.

Electrospinning (ES) produces fibers with small cross-sections and high surface area, making them ideal for a multitude of applications. Structures produced using ES methods exhibit a high surface-to-volume ratio, tunable porosity, and controllable composition. ES involves the delivery of a liquid or solid polymer to a spinneret, whereby, an initiated electric field pulls the polymer into micro to nano-scale fibers. Due to the multitude of applications for which polymer fibers can be used, it is desirable to provide an efficient and portable ES device that allows on-demand deposition of polymer materials. The invention that is subject of this patent application is a portable ES device that allows ideal deposition on a substrate regardless of whether that substrate is attached to high voltage or grounded, and regardless of whether or not there is a charged or grounded substrate behind the desired deposition surface.

An applicator is disclosed for applying a treatment solution to a treatment site of a patient. The applicator can include an applicator housing comprising a treatment solution reservoir. A cartridge can be removably disposed in the housing. The cartridge when arranged in the housing can be in fluid communication with the treatment solution reservoir. The cartridge can include an electrostatic module for electrostatically charging the treatment solution in the treatment solution reservoir; and a nozzle for applying the treatment solution.

Compositions and blends of biopolymers and copolymers are described, along with their use to prepare biocompatible scaffolds and surgically implantable devices for use in supporting and facilitating the repair of soft tissue injuries.

Described herein are nanofibers and methods for making nanofibers that include any one or more of (a) a non-homogeneous charge density; (b) a plurality of regions of high charge density; and/or (c) charged nanoparticles or chargeable nanoparticles. In one aspect, the present invention fulfills a need for filtration media that are capable of both high performance (e.g., removal of particle sizes between 0.1 and 0.5 μm) with a low pressure drop, however the invention is not limited in this regard.

High strength or load bearing nylon fiber with break tenacity greater than 7.5 g/den and/or a tenacity at 10% elongation of greater than 4.0 g/den as well as yarns, fabrics and articles of manufacture thereof and methods for their production are provided.

A staple cartridge assembly for use with a surgical stapling instrument includes a staple cartridge including a plurality of staples and a cartridge deck. The staple cartridge assembly also includes a compressible adjunct positionable against the cartridge deck, wherein the staples are deployable into tissue captured against the compressible adjunct, and wherein the compressible adjunct comprises a first biocompatible layer comprising a first portion, a second biocompatible layer comprising a second portion, and crossed spacer fibers extending between the first portion and the second portion.
