Technologies for fibers with nanotechnology is disclosed. In the illustrative embodiment, a preform is 3D printed with one or more sacrificial cores and one or more hollow channels. The preform is drawn into a fiber, and one or more metal core(s) is inserted into the hollow channel during the fiber draw. The fiber is then heated, breaking up the sacrificial cores into balls through capillary action. The fiber can be etched, exposing the balls made up of the sacrificial cores. The balls can be selectively etched, exposing the metal core(s) of the fiber. Additional embodiments are disclosed.

A wirelessly triggered device for implantation in vivo is disclosed herein. In a described embodiment, the wirelessly triggered device comprises an electrically conductive suture; and an electronic circuit coated with a biocompatible encapsulating material and communicatively coupled to the electrically conductive suture, the electronic circuit arranged to convert a received wireless triggering signal into an electrical signal for passing through the conductive suture. A reader for use with the device and an electrically conductive surgical thread is also disclosed, among other aspects.

The present application relates to fibers having a diameter of 1 nm to 10,000 nm, of one or more biocompatible polymers, wherein the polymers have a backbone which includes a positively charged component from a zwitterionic moiety. Additionally, this application discloses an implantable therapeutic delivery system and its method of formation, comprising a housing defining a chamber, wherein said housing is porous and formed from the fibers. Inside of the housing includes a preparation of cells which release a therapeutic agent from the chamber. The implantable therapeutic delivery system can be used in the treatment of diabetes.

The invention relates to bacteriophage means, namely intracorporal bacteriophage means, nasopharyngeal and pulmonary bacteriophage means, cutaneous bacteriophage means, and bacteriophage suture means, and in addition a two-syringe bacteriophage means, a nasopharyngeal and pulmonary bacteriophage means device, and a bacteriophage sensitive testing application.

The present invention relates to a nerve suture patch having a self-healing property, and a production method thereof, and more specifically, to a self-healing nerve suture patch containing a self-healing polymer and a hydrogel, and a production method thereof. The nerve suture patch may be rapidly attached to epineurium by the adhesiveness of the hydrogel and easily suture a damaged nerve.

An apparatus for forming a weld between a first portion of a biocompatible conductive thermoplastic material and a second portion of a biocompatible conductive thermoplastic material comprises a first electrode, a second electrode, and a structure for holding said first and second electrodes in opposition to one other with a space therebetween for receiving said first portion and said second portion in contact with one another. The structure is electrically non-conductive and an electrical circuit comprising a power source and a switch arranged such that closure of said switch applies a voltage potential across said first electrode and said second electrode so as to generate heat via electrical resistance, the heat being sufficient to melt regions of said first and second portions.

A staple cartridge comprising a tissue thickness compensator is disclosed. The tissue thickness compensator comprises an external layer and tubular elements. The tubular elements are interconnected and positioned within the external layer. The tubular elements comprise apertures defined therein and the tubular elements are configured to collapse as pressure is applied to the tissue thickness compensator by tissue during the firing motion. The apertures enable fluids from the tissue to permeate the tissue thickness compensator.

Some embodiments relate to additive manufactured articles having passivated surfaces and related methods. The methods may comprise forming a three-dimensional (3D) article by additive manufacturing to obtain an additive manufactured 3D article comprising a magnesium component. The method may further comprise exposing the additive manufactured 3D article to a reactive gas phase comprising a fluorine component. The fluorine component from the reactive gas phase may react with the magnesium component of the additive manufactured 3D article to form a passivation layer at and below a surface of the additive manufacture 3D article.
