  • Patent number: 11419632
    Abstract: Systems, devices, and methods are provided for transseptal access of septa within a patient. The device can be advanced to a septum, e.g., towards a fossa ovalis. Instead of applying positive pressure to “tent” the septum, a negative pressure is applied to a lumen within a sheath, e.g., within an elongated member slidable within the sheath, via a negative pressure source such as a syringe on the proximal end of the sheath. This results in the septum pulling inward. The sheath employs a stationary needle-like central core component contained within the lumen of the sheath that punctures the septum when the same is pulled passed it by the negative pressure. The stationary needle-like central core component may be hollow and may form a portion of the elongated member or may be coupled to a distal end thereof.

  • Patent number: 10532200
    Abstract: A device that may be placed on a biological barrier can be used to perforate the biological barrier for a variety of purposes such as cosmetic, scar treatment or for the delivery of active agents. A flexible substrate has a first side and a second opposing side and a plurality of micro-penetrator arrangements each comprising a head and a first and second projection, for penetrating a biological barrier, extending from the head. The first and second projection at least partially extend through the flexible substrate towards the first side. The head comprises an elongate arm for spacing apart the first and second projections. A force is applied to the second side causing flexing of the flexible substrate and pushing the projections into communication with a biological barrier.

  • Patent number: 10363394
    Abstract: Systems and methods are disclosed herein that generally involve CED devices with various features for reducing or preventing backflow. In some embodiments, CED devices include a tissue-receiving space disposed proximal to a distal fluid outlet. Tissue can be compressed into or pinched/pinned by the tissue-receiving space as the device is inserted into a target region of a patient, thereby forming a seal that reduces or prevents proximal backflow of fluid ejected from the outlet beyond the tissue-receiving space. In some embodiments, CED devices include a bullet-shaped nose proximal to a distal fluid outlet. The bullet-shaped nose forms a good seal with surrounding tissue and helps reduce or prevent backflow of infused fluid.
