Ultrasound catheter
A system and a method for disrupting an occlusion within a blood vessel is provided The system includes an elongated catheter body having a proximal portion, a distal portion, and a first lumen. The system further includes an ultrasound transmitter extending longitudinally through the first lumen of the catheter body and having a proximal end and a distal end. The system further includes a positioning mechanism located at a distal end of the catheter body. The positioning mechanism has a first retracted position and a second deployed position, and the positioning mechanism is radially expandable from the first retracted position to the second deployed position to position the catheter in the blood vessel.
CAROTID ARTERY EMBOLIC PROTECTION METHOD USING PERCUTANEOUS TRANSJUGULAR CAROTID FLOW REVERSAL
Methods and devices for performing transjugular carotid flow reversal are provided. A flow reversal sheath is advanced through a transjugular carotid fistula. An occlusion balloon is inflated, causing carotid inflow to be diverted through the sheath and through a flow reversal region positioned in the jugular vein. After reversal of blood flow, a carotid intervention is performed.
ENDOVASCULAR DEVICES AND METHODS
Devices and methods for the treatment of chronic total occlusions are provided. One disclosed embodiment comprises a method of facilitating treatment via a vascular wall defining a vascular lumen containing an occlusion therein. The method includes providing an intravascular device having a distal portion with a side port, inserting the device into the vascular lumen, positioning the distal portion in the vascular wall, directing the distal portion within the vascular wall such that the distal portion moves at least partially laterally, and directing the side port towards the vascular lumen.
Systems and methods for endovascularly accessing a subarachnoid space
Systems and methods for implanting an endovascular shunt in a patient is disclosed. The system having an expandable anchor configured for being deployed in a dural venous sinus of a patient at a location distal to a curved portion of a wall of an inferior petrosal sinus (IPS) of the patient; an elongate guide member coupled to, and extending proximally from, the anchor; a shunt delivery catheter having a first lumen configured to receive the guide member, and a second lumen extending between respective proximal and distal openings in the shunt delivery catheter, the shunt delivery catheter further having a penetrating element coupled to a distal end of the catheter; and the system further having a guard at least partially disposed over, and movable relative to, the penetrating element.
Rotatable medical device
A rotational atherectomy device including a drive shaft rotatably extending through an outer tubular member to rotate a cutting member positioned at a distal end thereof. The rotational atherectomy device further includes an elongate penetrator extendable distal of the cutting member a predetermined maximum distance and configured to stabilize the cutting member as the cutting member engages an occlusion to control the trajectory and advancement of the cutting member through the occlusion.
ENDOVASCULAR DEVICES AND METHODS
Devices and methods for the treatment of chronic total occlusions are provided. One disclosed embodiment comprises a method of facilitating treatment via a vascular wall defining a vascular lumen containing an occlusion therein. The method includes providing an intravascular device having a distal portion with a side port, inserting the device into the vascular lumen, positioning the distal portion in the vascular wall, directing the distal portion within the vascular wall such that the distal portion moves at least partially laterally, and directing the side port towards the vascular lumen.
DIRECTIONAL STENT FOR ACCESSING EXTRAVASCULAR SPACES
An extravascular access system includes a tubular stent configured to be deployed in a blood vessel, the stent having a sidewall and a proximal end opening and an internal scaffolding comprising one or more structural members, and an elongate access catheter having a distal end portion configured to access the blood vessel wherein when the stent is deployed in the blood vessel, and the distal end portion of the catheter is inserted into the proximal end opening of the stent, the one or more internal structural members of the stent deflect the distal end portion of the catheter towards a wall of the blood vessel.
