  • Publication number: 20210369296
    Abstract: An endoluminal punch system including a sheath and dilator. The endoluminal punch may include energy delivery system capable of being transmitted from the proximal end to the distal end of the endoluminal punch to assist with tissue crossing and incisions. The dilator may include selectively deployable cutting mechanism to create incisions in tissue that are larger than their basic external diameter. The system may also be configured to reduce the risk of generating plastic emboli during insertion of the endoluminal punch.

  • Publication number: 20210275211
    Abstract: Methods for performing certain medical procedures wherein a steerable endoluminal punch is used to not only gain access but to create a channel or punch through tissue, thus facilitating follow-up therapeutic procedures. The distal end of the steerable endoluminal punch is controllably articulated by the operator using a control device at the proximal end.

  • Publication number: 20210137547
    Abstract: An endoluminal punch with a penetrating stylet and a vibration generator. The vibration generator is operable to cause vibrations and rapid reciprocation of the distal tip of the stylet to facilitate penetration of the stylet through resistant body tissue such as the fossa ovalis. The vibration generator may also be operable to cause vibration of the distal tip of the punch itself, to facilitate passage of the punch through an initial perforation created by the stylet.

  • Publication number: 20210069430
    Abstract: Devices and methods are disclosed for protecting individuals from the sharp ends of medical objects following use on a patient. Such sharp objects include hypodermic needles, scalpel blades, cannulae, trocars, and the like. The protective cover is designed to surround and sequester the sharp in a shell that is will not permit further puncture or cutting with the sharp. In an embodiment, the protective cover also absorbs any fluids on or in the used sharp and prevents any fluids from escaping the protective cover. The devices are configured to be integral to procedure trays or kits such that space and discarded materials are minimized along with the potential for injuring someone with a used, contaminated medical sharp.

  • Publication number: 20210008353
    Abstract: This invention is a transvascularly placed steerable guidewire, 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 guidewire is generally fabricated from stainless steel and includes an outer tube, an inner tube, hub structures, and a distal articulating region. The steerable guidewire 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 steerable guidewire hub can be removed to permit advancement of catheters over its proximal end followed by re-attachment of the hub to permit deflection of the distal end of the steerable guidewire. Removal of the hub can result in a limp guidewire or maintenance of a forced curvature of the distal end of the guidewire.

  • Publication number: 20210000505
    Abstract: An endoluminal needle or punch is describes wherein the distal end of the endoluminal needle is able to articulate laterally out of the longitudinal axis of the steerable endoluminal needle. The endoluminal needle further comprise a blunted distal end configuration that is minimally traumatic. Under control by the user, at the proximal end of the endoluminal needle, a sharp stylet can be advanced to punch tissue and then be retracted to maximize safety. The endoluminal needle is configured for use within an introducer.

  • Patent number: 10722255
    Abstract: A catheter system can be used to remove obstructions, deliver implantable devices or substances, and/or restore flow through body lumens. The system can include an outer shaft having a lumen, sidewall, and a longitudinal window in the sidewall, an inner shaft disposed within the lumen, and an expandable member having a first end coupled to the outer shaft and a second end coupled to the inner shaft through the window. The expandable member can be positioned adjacent to a target region while in the collapsed configuration. The expandable member can be expanded to an expanded configuration by relative movement of the outer shaft and the inner shaft.
