  • Patent number: 12239779
    Abstract: Disclosed embodiments relate to devices and systems for providing both negative-pressure therapy and instillation, In some embodiments, both negative-pressure and instillation may be provided to a tissue site in a low-profile context that may also prevent siphoning of instillation fluid during negative pressure application. For example, a single bridge may include a negative-pressure pathway with supports and an instillation pathway, and the instillation pathway may be configured with respect to the negative-pressure pathway so that at least a portion of the instillation pathway collapses upon application of negative pressure to the negative-pressure pathway. Collapse of at least a portion of the instillation pathway may be sufficient to close the instillation pathway.

  • Publication number: 20250057560
    Abstract: An endoluminal punch and introducer sheath are described wherein the endoluminal punch comprises a guidewire lumen through which a user is capable of placing a guidewire. The endoluminal punch system further comprises a mechanism affixed to the hub which is capable of controlling the axial positioning of the guidewire relative to the endoluminal punch distal end. The control mechanism can be released so that the endoluminal punch can be removed from a patient while retaining the guidewire in place within the patient. The endoluminal punch introducer, including a sheath and dilator, can comprise energy emitting electrodes or transducers for cutting larger size holes in stubborn (friable, scarred, or fibrotic) tissue. In other embodiments, the endoluminal punch can comprise a guidewire or stylet, wherein the guidewire or stylet is capable of emitting energy to cut through tissue.

  • Patent number: 12226114
    Abstract: A transvascularly placed steerable microcatheter, further including internal steerability and the ability to articulate in a direction at right angles to its longitudinal axis at or near its distal end. The steerable microcatheter is generally fabricated from stainless steel, nitinol, or other metal and includes an outer tube, an inner tube, hub structures, and a distal articulating region. The steerable microcatheter can be advanced through a body lumen in its straight configuration and then be selectively articulated or curved to permit negotiation of tortuous curvature. The microcatheter is especially suited to robotic or powered control applications with user intervention or using artificial intelligence (AI).

  • Publication number: 20230082981
    Abstract: An infusion pump includes first and pumping segments configured to operate in parallel with each other, each pumping segment including a group of serially-aligned pumping elements configured to compress an elongated compressible channel loaded within the pumping segment. Each group of serially aligned pumping elements of the multiple pumping segments is caused to pump according to respective timing patterns offset from each other to deliver a first fluid from a first compressible channel loaded in the first pumping segment to a common delivery tubing while filling a second compressible channel loaded in the second pumping segment with a second fluid, and to deliver the second fluid from second compressible channel to the common delivery conduit while filling the first compressible channel using the first pumping segment.
