Abstract: The present invention is an enteral nutrition gastrostomy access device. A permanent or semi-permanent stoma liner is adjustably positioned within a stoma channel extending through a patient's abdominal and stomach walls. The stoma liner is characterized by an adjustable bladder capable of applying variable torsional force to one or more pinch points along the interface between the stoma liner and the stoma. The stoma liner is configured to receive a plug with a central threaded channel, into which a cap or enteral feeding device may be wholly or partially inserted. The central threaded channel is characterized by requiring application of a linear push force to apply but requiring application of both a linear pull force and a torsional force to remove.

Abstract: The embodiments herein are directed to a portable liquid delivery system that incorporates an immersion driving pump mechanism(s), an administration reservoir, a user interface, and a wearable and/or portable accessory. The wearable accessory serves to house the components of the system and is to be worn on the user's body. In some cases, the system may be used to deliver nutritional formula for the treatment of patients on an enteral nutrition regimen.

Abstract: A spectrally encoded endoscopic probe having high resolution and small diameter comprising at least one flexible optical fiber; an energy source; a grating through which said energy is transmitted such that the energy spectrum is dispersed; a lens for focusing the dispersed energy spectrum onto a sample such that the impingement spot for each wavelength is a separate position on the sample, the wavelength spectrum defining a wavelength encoded axis; means for mechanically scanning the sample with focused energy in a direction perpendicular to the wavelength encoded axis; a means for receiving energy reflected from the sample; and, a means for detecting the received reflected energy. The probe grating and lens delivers a beam of multi-spectral light having spectral components extending in one dimension across a target region and which is moved to scan in another direction. The reflected spectrum is measured to provide two dimensional imaging of the region.
