A cannula system and method for accessing a blood mass in the brain. The system comprises a cannula with a camera mounted on the proximal end of the cannula with a view into the cannula lumen and the surgical field below the lumen. A prism, reflector or other suitable optical element is oriented between the camera and the lumen of the cannula to afford the camera a view into the cannula while minimizing obstruction of the lumen. The system may also include an obturator with a small diameter shaft and a large diameter tip which is optically transmissive, so that a surgeon inserting or manipulating the assembly can easily see that the obturator tip is near brain tissue (which is white) or blood (which is red).

Cannula with proximally mounted camera and transparent obturator

A microcatheter with an enhanced inner liner that has low of friction and improved toughness which facilitates delivery of expandable vascular reconstruction devices.

Microcatheter with modified PTFE liner

A camera and expandable bladed retractor system. The system includes a camera, with a distal-most optical element disposed over the proximal end of the lumen or surgical channel established by the retractor blades. The camera may be fixed to the retractor, either to the proximal end of a blade or to a frame member.

Devices and method for access and visualization for lumbar interbody fusion (LIF)

A macerating and aspiration tool for removing blood masses from the brain.

Macerating and aspiration tool for intracranial surgery

Distal access aspiration guide catheter system and methods for delivering implantable devices, catheters, or substances in or near and/or restoring flow through body lumens, such as blood vessel lumens are described. A distal access aspiration guide catheter having a proximal, medial, and distal possessing high flexibility, high resistance to kinking and a large lumen to wall thickness ratio.

Distal access aspiration guide catheter

A parent artery occlusion (PAO) device which provides for immediate occlusion of a cerebral artery to isolate a defect. The PAO device includes a self-expanding wire-frame prolate structure which is partially covered with an ePTFE membrane.

Embolic implant and method of use

An aneurysm bridging device can be placed in the neurovasculature of a patient by advancing the aneurysm bridging device in a small-diameter configuration a delivery catheter to a target region within the neurovasculature and securing the distal region of the aneurysm bridging device to the neurovasculature. While the distal region of the aneurysm bridging device is secured to the neurovasculature, the proximal region of the aneurysm bridging device can be advanced to permit the aneurysm bridging device to expand from the small-diameter configuration and to deform and twist in a central region of the aneurysm bridging device. The proximal region of the aneurysm bridging device can be secured within the neurovasculature to maintain the central region of the aneurysm bridging device in a deformed state.

Protuberant aneurysm bridging device deployment method

Distal access aspiration guide catheter system and methods for delivering implantable devices, catheters, or substances in or near and/or restoring flow through body lumens, such as blood vessel lumens are described. A Distal access aspiration guide catheter having a proximal, medial, and distal possessing high flexibility, high resistance to kinking and a large lumen to wall thickness ratio.

In examples, a microcatheter includes an enhanced inner liner that has a low coefficient of friction and improved toughness, which facilitates delivery of expandable vascular reconstruction devices. The microcatheter may include a stretched polytetrafluoroethylene (PTFE) liner, which may be stretched longitudinally and not circumferentially or radially over at least a portion of a length of the microcatheter. The stretched PTFE inner liner may result in the reduction of a delivery friction and improved toughness and resistance to scraping.
