    Abstract: A device for creating a fistula between blood vessels operates in conjunction with a guidewire to locate and position itself so that it straddles both vessels and is able to draw them together. A fixing agent is released either from within the device or from an external needle, or both, into the procedural site. The fixing agent functions to hold the relative position of the two vessels, to seal the surrounding tissue so that any leaks that do occur don't spread into the tissue to create a hematoma, and to limit expansion of the fistula. After the vessels are in close proximity to each other and the fixing agent is applied, the device of the invention employs a cutting mechanism which opens a portal between the two vessels.

  • Patent number: 10646270
    Abstract: Surgical instruments having articulating portions or joints are described herein. In one embodiment, a surgical instrument can include a distal end effector, a proximal actuating portion, and an articulating portion disposed between the end effector and the actuating portion. The articulating portion can include an inner component formed of a first material and an outer component formed of a second material, wherein a modulus of elasticity of the first material is higher than a modulus of elasticity of the second material. Such an instrument can be less complex and less expensive than known articulation mechanisms while providing similar capabilities.

  • Patent number: 10625067
    Abstract: A novel seal is provided along with a valve for implementing the seal in the form of a hemostatic catheterization valve. A pressure-sensing form of the hemostatic valve is also provided. The novel seal includes a pair of cooperating conical gaskets divided through their apexes into a plurality of edge-abutting semi-conical flaps. The seals are angularly fixed in orientation relative to each other using registering structures such as complementary tabs and sockets. More specifically, the seams where the semi-conical flaps abut are angularly off-set between the two conical gaskets by a predetermined amount.

  • Patent number: 10596312
    Abstract: A low-cost and simple-to-use system and method to facilitate a prophylactic pleural lavage protocol at the time of thoracostomy tube placement for traumatic hemothorax in order to reduce the need for secondary intervention for the management of retained hemothorax. The invention may be used in conjunction with existing chest tubes and be administered at the time of initial chest tube placement, and continued at the bedside (by a bedside nurse) over the duration of chest drainage, as necessary. The system includes an operator device that semi-automatically administers a pleural lavage protocol consisting of saline instillation, and suction to slow the clotting process, prevent “gelling” of blood, and maintain drainability.

  • Patent number: 10576246
    Abstract: A catheter-based/intravascular ablation (denervation) system includes a multiplicity of needles which expand open around a central axis to engage the wall of a blood vessel, or the wall of the left atrium, allowing the injection of a cytotoxic or/or neurotoxic solution for ablating conducting tissue, or nerve fibers around the ostium of the pulmonary vein, or circumferentially in or just beyond the outer layer of the renal artery. The expandable needle delivery system is formed with self-expanding materials and include structures, near the end portion of the needles, or using separate guide tubes. The system also includes means to limit and/or adjust the depth of penetration of the ablative fluid into the tissue of the wall of the targeted blood vessel. The preferred embodiment of the catheter delivered through the vascular system of a patient includes a multiplicity of expandable guide tubes that engage the wall of a blood vessel.

  • Patent number: 10576260
    Abstract: Adaptors, cannulas, caps, tube couplers, and systems thereof provide endovascular access through an established ECLS system. Adaptors having curved or angled shafts navigate right angle side ports of standard bypass cannulas and permit hemostatic introduction and direction of an intervention device to the axial flow path of the cannula lumen and bypass system. A modified cannula having an angled side port is also provided for use as an arterial cannula. A cap having an occluding surface may be inserted into the angled side port to prevent blood from stagnating in the angled side port. A tube coupler is also provided having an access port, such as an angled access port, and may be spliced into an established bypass system for vascular access point. Multiple couplers can be used to provide multiple access points. The adaptors and occlusive cap are interchangeable with each other and with secondary circuits.
