  • Patent number: 12257403
    Abstract: Vascular access devices and methods of their use are provided. In one embodiment, a vascular access device includes a catheter and at least one deployable wire. The catheter includes a primary lumen extending from a proximal end to a distal end of the catheter. The at least one deployable wire is secured to the catheter and configured to move relative to the catheter between a delivery configuration and a deployed configuration.

  • Patent number: 11957355
    Abstract: Vascular access devices, systems, and methods of their use are provided. In one embodiment, a vascular access device includes a catheter, a balloon, and an inflation lumen. The catheter includes an elongate flexible shaft having a proximal end and a distal end with a primary lumen therethrough. The balloon is disposed about the distal end of the catheter. The inflation lumen is in fluid communication with the balloon and extends toward the proximal end of the shaft of the catheter. The balloon is inflatable into a shape having a first open end, a second open end, a sidewall between the first and second open ends, and a passageway therethrough, which, when the balloon is deployed and inflated within a vessel, permits blood flowing in the vessel to flow through the passageway.

  • Patent number: 10960188
    Abstract: Treatment methods and devices are provided for percutaneously accessing a patient's thoracic region via a controlled opening in the aorta, so that cardiac procedures, such as a coronary bypass procedure, can be performed in a minimally invasive manner. Advantageously, it may be possible to perform the procedure without placing the patient on cardiopulmonary bypass. The method may include percutaneously delivering at least one catheter into an aorta of a heart, forming a controlled opening in the aorta and pericardium via the at least one catheter to access a thoracic region within the patient's chest, and performing at least one coronary bypass graft procedure through the controlled opening.
