The present invention relates to biomaterial in the form of dispersion of cellulose nanofibrils with extraordinary shear thinning properties which can be converted into desire 3D shape using 3D Bioprinting technology. In this invention cellulose nanofibril dispersion, is processed through different mechanical, enzymatic and chemical steps to yield dispersion with desired morphological and rheological properties to be used as bioink in 3D Bioprinter. The processes are followed by purification, adjusting of osmolarity of the material and sterilization to yield biomaterial which has cytocompatibility and can be combined with living cells. Cellulose nanofibrils can be produced by microbial process but can also be isolated from plant secondary or primary cell wall, animals such as tunicates, algae and fungi. The present invention describes applications of this novel cellulose nanofibrillar bioink for 3D Bioprinting of tissue and organs with desired architecture.

An implant comprising an implant body, wherein the implant body comprises one or more regions of macro-texturisation on a surface of the implant body. Various methods of making an implant comprising one or more regions of macro-texturisation on a surface of the implant body are described, the methods being (i) making an implant comprising forming a shell on a mandrel, wherein the mandrel is shaped to form regions of macro-texturisation in the shell and filling the shell with a core material; (ii) making an implant comprising securing a scaffold comprising a silicone polymer to a surface of an implant body or (iii) making an implant comprising extruding a material that will form regions of macro-texturisation onto an implant body or (iv) making an implant comprising laser etching a surface on an implant body to form regions of macro-texturisation.

Described herein are eye implants that can include a pressure-responsive material that can be capable of changing color in response to pressure exerted on it. Also described here are methods of implanting and using the eye implants described herein to monitor intraocular pressure in a subject. The pressure-responsive material can be used to diagnose and monitor human or animal subjects.

A coated medical device (10) including a structure (12) adapted for introduction into a passage or vessel of a patient. The structure is formed of preferably a non-porous base material (14) having a bioactive material layer (18) disposed thereon. The medical device is preferably an implantable stent or balloon (26) of which the bioactive material layer is deposited thereon. The stent can be positioned around the balloon and another layer of the bioactive material posited over the entire structure and extending beyond the ends of the positioned stent. The ends of the balloon extend beyond the ends of the stent and include the bioactive material thereon for delivering the bioactive material to the cells of a vessel wall coming in contact therewith. The balloon further includes a layer of hydrophilic material (58) positioned between the base and bioactive material layers of the balloon.

The invention relates to stents, in particular to a stent assembly for insertion in a vessel of a human or animal body.

The invention also relates to a catheter stent insertion device for inserting a stent assembly according to the invention in a vessel of a human or animal body.

The invention also relates to a method for inserting a stent assembly according to the invention in a vessel of a human or animal body using a catheter stent insertion device according to the invention.

Multilumen implant for application in human and animal vascular systems/bodies, with a substantially tubular element (1) divided into a proximal (2) and a distal section (3), and a fixation element (8) for the fixation of the proximal section (2) in a target vessel, wherein the tubular element (1) branches into two or more lumens (4, 5) in the distal section (3), with the fixation element (8) being at least one clamping ring (8) arranged on the outside of the proximal section (2) of the tubular element (1), and wherein the free end of the proximal section of the tubular element (1) is folded around the clamping ring (8) and embraces the clamping ring (8) in a pocket-like manner.

The disclosure provide a device for protecting the hearing of animals. The device is a sound protection cap constructed of formable material, e.g., a soft acoustical material, and adjustable straps to comfortably fit over the ears and on the head of an animal, such as a dog. The sound protection cap can come in different sizes to insure a good fit regardless the ear type or head shape of the animal. The multiple adjustments and formable material allows the sound protection cap to conform around the ears/head of the animal and stay in place. The sound protection cap can be positioned on an animal to provide hearing protection throughout exposure to loud sounds. In one example, the sound protection cap includes: (1) an adjustable attachment system (AAS) and (2) an external ear cover (EEC) coupled to the AAS, wherein the EEC includes a sound reduction layer of a moldable material.
