Abstract: This disclosure relates to a new type of needed for a subcutaneous port or for any use where blood is recycled, and more precisely to a needle with reduced friction openings for easing blood and its elements along a passageway made of a through bore in the body of a needle. The needle includes an oval shape opening for increased mechanical resistance of the needle while allowing a greater passage curvature of the blood cells at the greatest zone of passage. In other embodiments, a plurality of staggered openings is used to reduce the flow through any single opening where damage occurs, the openings can be made in a curved area, or a plurality of smaller openings or a grid made of openings can be used to further reduce the interference of the needle tip and the needle openings on blood.

Abstract: The present disclosure generally relates to a tool, a kit including said tool, and a method of use of the tool or the kit for making a subcutaneous pocket in a layer of fat for the introduction of a subcutaneous medical device, and more specifically, a tool, kit, and method of use thereof using a calibrated inflatable volume with a guide to open a subcutaneous pocket at the appropriate location in a body by inflating the volume to the appropriate size. The tool is calibrated to rest against a layer of muscle using a guide wire and inflate in a specific shape to a specific volume to gently displace fatty tissue that may obstruct the implantation of a subcutaneous device between the skin and the ultimate resting place. The tools allows for creating localized lateral retraction in an area of interest without placing strain on the skin or the muscle. A kit using the tool further includes surgical equipment needed for the surgery.

Abstract: The present disclosure generally relates to an multisegment interconnect device for permanently connecting adjacent elastic tubes, catheter ends, or other fluid transportation conduits where tubes are push-locked over conical outer ends each with a locking lip, the segments are connected at an interface, and the segments are adapted in length or geometry to permanently connect the tubes and hold a different length of tube over the body of the multisegment interconnect device.

Abstract: This disclosure relates to a fixed- or variable-length, wire-reinforced catheter for use in a human body or connected to a subcutaneous port implanted in a human body for use under a cyclical internal load and method of adaptation thereof, and more particularly, to a wire-reinforced catheter of increased internal diameter or reduced external diameter of fixed or variable lengths for the optimized transportation of blood under cyclical internal load and without damage.
