The method can include monitoring microflora intestinal gas concentration levels associated with a patient and adjusting the volume of nutrient provided by the patient with an artificial feeding device based at least in part on the microflora intestinal gas levels associated with the patient. A microflora intestinal gas sensor can be used to monitor the microflora intestinal gas associated with the patient. The microflora intestinal gas sensor can monitor the microflora intestinal gas in a patient's exhaled breath or in the patient's digestive tract. The microflora intestinal gas sensor be included as part of an enteral feeding system at the distal end or outside end of an enteral feeding tube. Systems and methods for monitoring nutritional uptake of an infant based on microflora intestinal gas levels associated with the infant are also disclosed.

  • Patent number: 9993633
    Abstract: A vascular access device, for implantation at least partially below the skin of a patient to provide an arteriovenous fistula, includes a graft portion coupled to a catheter portion. The graft portion is sutured to an opening in an artery while the catheter portion is inserted into a vein so that its end lies within the vein downstream from the point of entry into the vein. The device may be comprised of ePTFE with an outer polyurethane coating or the graft portion may comprise ePTFE with an outer polyurethane coating and the catheter portion may comprise polyurethane. There may also be an inner polyurethane coating. Alternatively, the device may be comprised entirely of polyurethane.

  • Patent number: 9962165
    Abstract: Apparatus for delivering material into a patient includes a catheter having a proximal end and a distal end. Material, preferably of filamentary or thread form, is fed from a material supply into a Y-fitting having a main branch and a side branch. The side branch is connected to a source of driving fluid able to feed drive fluid under pressure into the material carrier so as to pull material forwardly and out of the distal end of the catheter. The assembly includes an inner cannula within which material is passed from the material source. This increases the speed of delivery of material though the device and reduces the amount of drive fluid which is required.

  • Patent number: 9931191
    Abstract: The invention relates to a device (1), especially a tube or a catheter, for at least partially introducing into a body passage, said device comprising a long outer envelope body (10), a long inner body (11) that is partially peripherally surrounded by the envelope body (10), and a device (12) by which means the possibility of a relative movement between the envelope body (10) and the inner body (11) is enabled or impeded in a targeted, controllable manner. According to the invention, the control device (12) is formed by the arrangement and embodiment of the envelope body (10) and the inner body (11) and comprises no additional mechanical means in the annular intermediate region (13) between said two bodies (10, 11). Preferably, the control device is embodied in such a way that it acts on the friction between the envelope body and the inner body (10, 11).

  • Patent number: 9925326
    Abstract: A cannula ingress system may include a tip stabilization mechanism having a tip stabilization mechanism distal end and a tip stabilization mechanism proximal end, a fixation mechanism, a hypodermic tube having a hypodermic tube distal end and a hypodermic tube proximal end, and a tip having a tip distal end and a tip proximal end. The tip may be disposed within the hypodermic tube wherein the tip distal end extends from the hypodermic tube distal end. The fixation mechanism may be disposed within a fixation mechanism channel of the tip stabilization mechanism. The tip stabilization mechanism may be disposed over the tip and the hypodermic tube distal end.

  • Patent number: 9924888
    Abstract: A system and method for treating Parkinson's disease by delivery of an agent within the brain. At least one image of a target region is acquired, and at least one magnetic resonance diffusion tensor imaging (MR-DTI) scan of the target region is acquired. A diffusion tensor is calculated from the at least one MR-DTI scan, and at least one of an agent distribution and an agent concentration from the images and the calculated diffusion tensor is calculated. Using at least one of the calculated diffusion tensor, the images, the calculated agent distribution, and the calculated agent concentration, the placement of a delivery instrument is planned to deliver the agent to the target region to achieve a desired agent concentration and/or agent distribution within the target region. Delivery of the agent can be coordinated with an applied electrical stimulation.
