  • Patent number: 11857193
    Abstract: Disclosed embodiments include apparatuses, systems, and methods for facilitating surgical anastomosis between bodily passages. In an illustrative embodiment, an eversion mechanism is configured to partially evert a distal portion of an opening of a receiving passage and further configured to leave a proximal portion of the opening of the receiving passage in a non-everted position. A donor support mechanism is configured to partially evert a distal portion of an opening at an end of a donor passage and further configured to leave a first proximal portion of the end of the donor passage in a non-everted position. The donor support mechanism is further configured to form a passage juncture at the end of the donor passage and the opening of the receiving passage. A suturing mechanism is configured to motivate a filament through a generally helical path around the passage juncture to suture the donor passage to the receiving passage.

  • Publication number: 20230284572
    Abstract: This invention provides a device and method for upwelling large amounts of cool, nutrient rich water by moving or pulling the device behind surface or subsurface marine vehicles to cool and/or enrich the surface and near-surface waters of selected oceanic regions. This invention also provides a device to upwell cool oceanic water from depth and use it to propel a vessel. This invention also provides a method for altering the course or intensity of cyclonic storms to reduce human and property damage from such storms by selective cooling of regions of ocean surface. This invention also provides a device and method for augmentation of the natural coastal upwelling of vital nutrient rich waters.

  • Patent number: 11033271
    Abstract: Disclosed embodiments include apparatuses, systems, and methods for facilitating surgical anastomosis. In an illustrative embodiment, an apparatus includes a first connector configured to engage an opening of a donor passage. A second connector is configured to engage an opening in a receiving passage. A separator is configured to support the first connector and the second connector and to fix relative positions of the end of the donor passage to edges of the opening in a receiving passage across a gap. The separator is configured to maintain the gap between the first connector and the second connector while multiple loops of a suture are passed through the edge of the opening in the donor passage and the edges of the opening in the receiving passage. The first connector, the second connector, and the separator are further configured to be removed from between adjacent loops of the multiple loops of the suture.

  • Patent number: 10702293
    Abstract: A method is disclosed for treating calcified lesions within a wall of a blood vessel. The first step includes breaking apart a calcified lesion using a plurality of shockwaves generated in an angioplasty balloon of an angioplasty catheter device. The angioplasty balloon is dilated via a fluid to a first extent to fit against at least a portion of the wall of the blood vessel. A plurality of electrical pulses are delivered to a pair of electrodes disposed within the fluid inside the balloon. The electrical pulses have an amplitude sufficient to create plasma arcs in the fluid to generate shockwaves that are conducted through the fluid and through the balloon to the blood vessel, to crack the calcified lesion. After breaking apart the calcified lesion, the angioplasty balloon is allowed to further expand to a second extent greater than the first extent, thereby expanding an opening in the blood vessel.
