  • Patent number: 10682453
    Abstract: A system for providing a continuous flow of blood between two locations in a cardiovascular system of a patient is provided. The system includes a blood conduit having a proximal portion configured to be attached to an artery. The system also includes a distal portion configured to be inserted into a blood vessel at an insertion site and to be advanced there through to a location spaced apart from the insertion site. Moreover, the system includes a reinforcement member positioned at least partially about the blood conduit in at least one of the distal portion, the proximal portion, or a combination thereof.
    Type: Grant

  • Publication number: 20180078697
    Abstract: A connector for fluidly coupling proximal and distal tubular segments of a fluid conduit is provided. In one embodiment, a system is provided for providing continuous flow of blood between two locations in a patient's cardiovascular system. A first blood conduit is provided that has a distal portion and a proximal portion. The distal portion is adapted to be inserted into a blood vessel at an insertion site and to be advanced therethrough to a location spaced apart from the insertion site. The system is provided with a connector that has a distal portion adapted to be engaged with the proximal portion of the first blood conduit and a tubular body extending proximally of the distal portion. The tubular body is adapted to be inserted into and/or attached to an end of a second blood conduit, such as a vascular graft or the like.

  • Patent number: 9198825
    Abstract: Medical devices with novel spark gap electrode designs, able to control manually or automatically the electrodes gap are provided. These devices are used to generate a shock wave created by the rapid expansion and collapse of a plasma bubble that is formed between two spark gap electrodes placed in a special liquid medium, when a high differential voltage (kV) is applied to the electrodes. The resulting shock wave impacts a reflector to direct the energy into the body of an animal or a human toward the desired treatment location. This electro-hydraulic principle to create acoustic shock waves as a method of treatment is in use in the medical (lithotripsy, orthopedic use, wound treatment, burns, post-operative treatment, pain treatment, diagnosis, skin and organ transplantation supporting devices, arteriosclerosis treatment), cosmetic (treatment of scars and cellulite) and veterinary (treatment of musculoskeletal disorders) fields.

  • Publication number: 20150051532
    Abstract: Systems and methods for a blood conduit for fluidly coupling a first vascular segment to a second vascular segment are disclosed herein. In one embodiment, a system for fluidly coupling proximal and distal tubular segments of a fluid conduit in a cardiovascular system is provided. The system may include a first engagement feature disposed on a distal end of the proximal tubular segment. The system also may include a second engagement feature disposed on a proximal end of the distal tubular segment. The first engagement feature may be configured to mate with the second engagement feature. In this manner, continuous flow may be provided between the proximal and distal tubular segments of the fluid conduit. In another embodiment, the proximal and distal tubular segments of the fluid conduit may collectively form a single unitary lumen without a connection device interposed between the segments.

  • Publication number: 20060264996
    Abstract: A lancing device and replaceable multi-lancet cartridge for use in sampling of body fluids. Sequential lancets of the cartridge are translationally retracted along a storage path, pivoted into an angularly offset firing path, and translationally propelled by a drive mechanism to lance the subject's skin.
