9 results about "Arteriotomy" patented technology

A pressure relief device for use in a percutaneous procedure, the device comprising a tube having a distal opening into an internal lumen and a proximal opening from the internal lumen, a length of the tube sized to position the distal opening near a closed arteriotomy in a vessel and the proximal opening remains external to a patient's skin. Related devices, kits, and methods are provided.

To provide a method and a system for placing am embolic filter in a good aortic arch.SOLUTION: An embolic filter positioning system includes a vascular delivery sheath, a filter catheter, a self-expanding embolic filter attached to a distal end of the filter catheter, and an elongate dilator having a tapered dilator tip. The elongate dilator is slidably received in a central lumen of the filter catheter, and the filter catheter is slidably received in the open lumen of the vascular delivery sheath. The tapered dilator tip is positioned distally of the distal end of the vascular delivery sheath, and the self-expanding embolic filter is radially constrained in a proximal portion of the open lumen of the vascular delivery sheath. The tapered dilator tip has an expanded configuration where it covers the open distal end of the vascular delivery sheath and facilitates entry though an arteriotomy and a contracted configuration where it can be retracted through the central lumen of the filter catheter.SELECTED DRAWING: Figure 6

Disclosed are various embodiments and related methods of an arteriotomy formation system that can include a center puncturing device and an arteriotomy formation device. The center puncturing device can include a puncturing element that forms a puncture along a wall of a first vessel at a position central to a conduit passageway of a conduit. The arteriotomy formation device can include a tissue fixation element, a tissue capturing element, and a tissue cutting element. The arteriotomy formation device can form an arteriotomy along the first vessel such that the arteriotomy is centered relative to the conduit passageway.

A device for establishing a fluid communication pathway to a target point in a patient includes a bi-plane ultrasound probe. A transverse plane of the probe identifies a target point in the patient, and a longitudinal plane of the probe is used to monitor 2D ultrasound signals in a segment of an artery extending downstream from the target point. By moving the longitudinal plane to optimize the received 2D ultrasound signals, a pathway to the target point is thus determined for the medical use of arteriotomy needles and / or catheters.

Arterial closure devices as well as methods for making using arterial closure devices are disclosed. An example arterial closure device may include a proximal gasket configured to be positioned on a first side of a blood vessel wall. The arterial closure device may include a distal footplate configured to be positioned on a second side of the blood vessel wall opposite the proximal gasket. The arterial closure device may include a seal configured to be positioned on the first side of the blood vessel wall between the proximal gasket and the blood vessel wall. A tether may be coupled to at least the proximal gasket and the distal footplate. A securement element may be disposed on the tether. The securement element may be configured to secure the proximal gasket and the seal against the first side of the blood vessel wall.

To provide a system and the like for accessing a medical device.SOLUTION: Access sleeve (200) may be attached to a medical device having a first end disposed within a patient and a second end disposed outside of the patient. The access sleeve includes a tubular sleeve body (210) having a first open end (225) and a second open end (235), the first and second open ends defining a first lumen (215) extending along a longitudinal axis (205) of the sleeve body. An opening (260) in the sleeve body connects the first lumen to the outer surface of the sleeve body. The access sleeve may be selectively attached to a medical device (e.g., a catheter of a heart pump) and inserted into the access site when the medical device is disposed within the patient. The access sleeve can maintain vascular access to the access site (e.g., arteriotomy) of the patient and can be removed without disturbing the position of the medical device.SELECTED DRAWING: Figure 2
