A multiple function laryngoscope to be used for the safe intubation of a patient's trachea during a respiratory emergency or as an elective procedure. A two section instrument. Proximally, a reusable handle that houses a rechargeable battery, electronic circuits that feed a distal digital image to variable position LCD screen or viewing port, switches and low battery indicator light. Distally, the handle electrically couples with a disposable curved scabbard. The scabbard features a dorsal endotracheal tube channel with a wavy opening which allows preloading and gentle extraction of different size endotracheal tubes once the patient's trachea has been intubated. The scabbard's distal end strategically houses a distal sweeper that engages the epiglottis and exposes the glottis, an opening for the exit of a preloaded endotracheal tube, a LED light, a suction / oxygenation port, and a lens coupled with a digital imaging system (CMOS) to digitize and transport a distant wide field of view. Safe LCD view of one or serial rapid intubations are possible by rapidly replacing for a clean disposable scabbard in case of multiple emergencies.

This application describes an implantable device for tissue repair comprising at least two fabrics with interconnecting spacer elements transversing, connecting, and separating the fabrics, forming the device. Some embodiments have fixation points which can be an extension of at least one of the fabrics. The implantable device allows modification of the two fabrics having varying constructions, chemistries, and physical properties. The spacer elements create a space between the two fabrics, which can be used for the loading of biological materials (peptides, proteins, cells, tissues), offer compression resistance (i.e. stiffness), and compression recovery (i.e., return to original dimensions) following deformation and removal of deforming load. The inclusive fixation points of the fabrics are designed to allow for fine adjustment of the sizing and tension of the device to promote integration with the surrounding tissues as well as maximize the compressive resistance. The fixation points can include either the first fabric, the second fabric, or the combination of both fabrics. This device is suitable for soft and hard tissue regeneration or replacement with a preference for musculoskeletal tissues including but not limited to cartilage (including hyaline (referred to as articular, e.g. cartilage on the ends of long bones), fibrous (e.g. meniscus or intervertebral discs), elastic (e.g. ear, epiglottis)), bone, muscle, tendon, ligament, and fat.
