The invention provides devices, systems and methods for tissue approximation and repair at treatment sites. The devices, systems and methods of the invention will find use in a variety of therapeutic procedures, including endovascular, minimally-invasive, and open surgical procedures, and can be used in various anatomical regions, including the abdomen, thorax, cardiovascular system, heart, intestinal tract, stomach, urinary tract, bladder, lung, and other organs, vessels, and tissues. The invention is particularly useful in those procedures requiring minimally-invasive or endovascular access to remote tissue locations, where the instruments utilized must negotiate long, narrow, and tortuous pathways to the treatment site. In addition, many of the devices and systems of the invention are adapted to be reversible and removable from the patient at any point without interference with or trauma to internal tissues.

An illumination unit for illuminating an area of operation during open surgery. The illumination unit including: a body; a fiber bundle configured to guide light towards a distal end of the body, and a reflector body arranged at the distal end of the body. Where at least a part of the fiber bundle is guided inside the body along a longitudinal direction, the fiber bundle is split up into a plurality of optical fibers which form a fiber layer on an inner surface of the body, end faces of the plurality of optical fibers are arranged at the distal end of the body, the reflector body encloses the end faces of the plurality of optical fibers in a radial direction and extends distally beyond the distal end of the body in the longitudinal direction, and an inner surface of the reflector body is a reflective surface.

Compositions containing self-assembling peptides and / or self-assembling peptidomimetics (“self-assembling peptides”) can be used to create a long-lasting “lift” or means of elevating tissue to be resected, dissected, manipulated or repaired, as a bulking agent, or as a tissue forming matrix by injection of a solution that forms a solid gel in situ, which is stable for a prolonged period of time from days to a month, is hemostatic, and may prevent adhesions. These self-assembling peptides and methods of use thereof enable better separation of tissues and visualization of margins, more durable and robust lifts, less need for frequent injections that carry risk of undesired perforation, and simultaneous management of adverse effects, such as bleeding, leaking, inflammation and iatrogenic injury during endoscopic, laparoscopic or other minimally invasive, or open surgical procedures in and / or on the body.

A system and method for excising tissue from a stenotic spinal region is disclosed. The system may comprise a surgical kit including an access instrument, a bone reamer, a bone removal instrument, and a soft tissue removal instrument. The access device may be cannulated and utilized to achieve a path for the insertion and advancement of the other surgical instruments towards a target area, such as the interlaminar region. The bone removal and / or soft tissue removal instrument may be used at various angular orientations and depths within the lumbar region to ergonomically excise compressive features including hypertrophied ligamentum flavum. Minimally invasive and open procedures are disclosed.

The present application relates to a screw planning method and a rod insertion navigation method for spinal screw placement surgery. The screw planning method comprises: according to a screw planning algorithm, planning and obtaining initial screw positions, wherein the initial screw positions comprise positions of a plurality of screws that need to be set; according to the initial screw positions and screw sizes, screening a target rod path meeting a preset preference condition, wherein a rod is configured for insertion through the plurality of screws; and determining a target screw position according to the target rod path. The screw planning method aims to solve the problems in the related art that the screw planning algorithm has certain errors, requires manual adjustment in open surgery, and is difficult to apply to minimally invasive screw placement surgery.

Methods, devices, and systems establish and facilitate retrograde or reverse flow blood circulation in the region of the carotid artery bifurcation in order to limit or prevent the release of emboli into the cerebral vasculature such as into the internal carotid artery. The methods are particularly useful for interventional procedures, such as stenting and angioplasty, atherectomy performed through a transcarotid approach or transfemoral into the common carotid artery, either using an open surgical technique or using a percutaneous technique, such as a modified Seldinger technique or a micropuncture technique.
