A non-compliant medical balloon may be changed from a deflated state to an inflated state by increasing pressure within the balloon. The non-compliant medical balloon is composed of randomly oriented fibers forming an angle. The angle remains substantially unchanged when the balloon changes from a deflated state to an inflated state.

The present invention provides an implantable bioreactor comprising cells enclosed within an enclosure, said cells being capable of producing paracrine factors, wherein the enclosure is collapsible or expandable or both or neither, wherein the enclosure is semipermeable such that it provides containment of the cells preventing the egress of the cells while further providing a barrier that shields the cells from immunological attack, and wherein the enclosure is permeable to the entire secretome of the cell including exosomes, nucleic acids and proteins. The implantable bioreactor can have various configurations and can house internally a cell culture matrix than can include hydrogels, microbeads, and nanofiber matrices along with other active agents.

The present disclosure is directed toward a composite balloon comprising a layer of material having a porous microstructure (e.g., ePTFE or expanded polyethylene) and a thermoplastic polymeric layer useful for medical applications. The layers of the composite balloons become adhered through a stretch blow-molding process. Methods of making and using such composite balloons are also described amongst others.

A biocompatible soft tissue implant for introduction into a human body includes at least one layer comprising an elastomeric material, and at least one textile fabric arranged on the at least one layer comprising the elastomeric material. The at least one textile fabric forms a surface of the biocompatible soft tissue implant. The at least one textile fabric includes bioresorbable fibers which are embedded at least partially in the at least one layer comprising the elastomeric material.

A biocompatible composite material for complete or partial insertion into a human body includes at least one layer comprising an elastomeric material, and at least one textile fabric arranged on the at least one layer comprising the elastomeric material. The at least one textile fabric forms a surface of the biocompatible composite material. The at least one textile fabric includes bioresorbable fibers that are embedded at least partially in the at least one layer comprising the elastomeric material.

A tensile-force-enhancing tube for an implantable electrode lead or a catheter includes a tubular braid which is embedded in an elastomer material, wherein the braid comprises at least one cross thread and at least one axial thread.

A microcatheter comprising an inner layer, a strike layer and an outer layer and a braided skeleton located between the inner layer and the outer layer, wherein the inner layer is made of Polytetrafluoroethylene (PTFE) and has a thickness of 0.0015 inch or less, wherein the strike layer includes a polyether block amide and has a thickness of 0.001 inch or less, and wherein a distal portion of said outer layer is made of polycarbonate-based thermoplastic polyurethane having a shore of 90A or below.
