Components for an endoscopic vessel harvesting system suitable for harvesting target vessels such as the saphenous vein or radial artery for cardiac artery bypass graft surgery. The main components of such systems include a vessel dissector and a vessel harvester, both of which work in conjunction with a separately provided endoscope. The vessel dissector is an elongated cannula having a blunt tip for separating layers of facial around vessels. The tip may be movable, and is typically transparent to permit viewing forward of the tip using the endoscope. Internal features of the tip may reduce glare back to the endoscope. Several devices improve visibility through the tip by reducing interference from tissue or fluid on the tip. The vessel harvester also has an elongated cannula for receiving the endoscope. Several tools within the harvester permit manipulation, severing, and sealing of vessels forward of the distal end. The tool for manipulating vessels may have a low-profile for increased visibility of operation, and may be coupled to the cannula with a damping mechanism to reduce the possibility of avulsion of the vessels. Various vessel cutting and sealing devices are provided that may accommodate various sizes of vessels and improve cutting and sealing efficacy.

A device and method for visualization of the intravascular creation of autologous valves, and particularly venous valve, is disclosed herein. One aspect of the present technology, for example, is directed toward a delivery catheter that can include a lumen configured to receive a dissection assembly and a trough having a plurality of transducers electrically coupled to a proximal portion of the delivery catheter. At least one of the transducers can be configured to emit a signal towards a portion of a blood vessel adjacent the trough, and at least one of the transducers can be configured to receive a reflection of the emitted signal.

A rotatable jaw device for use with an endoscope. The device includes a fork, and two jaws pivotally mounted to the fork. The jaws are movable between a predetermined closed position and a predetermined open position. At least one jaw has at least one protrusion on a surface of the jaw. The at least one protrusion prohibits movement of the two jaws in the opening direction beyond the predetermined open position. One jaw may have an elongated center void defined by twin jaw extensions, and the other jaw may rotate within the elongated center void when the two jaws move toward the predetermined closed position.

A blood vessel dissecting device is disclosed, which includes a dissecting device configured to be inserted into a living body along a blood vessel to dissect tissue surrounding the vessel from tissue surrounding the vessel in a direction along a longitudinal extent of the blood vessel; and a cutting device configured to fee inserted into the living body along the longitudinal extent of the blood vessel to cut the tissue surrounding the blood vessel so the direction of longitudinal extent of the blood vessel.

An integrated clot evacuation device having visualization for use in neurosurgical applications, particularly for the evacuation of clots formed as a result of intracranial hemorrhage (ICH). The device may further include an integrated camera and light for visualizing the interior of the brain and the clot itself. Further, the device is configured to evacuate clots through aspiration and irrigation.

Disclosed are access devices that can be used to safely guide instruments, such as EP ablation catheters, to a therapy site such one within the pericardial space of the heart. The access devices include integrated visualization, illumination, stabilization, and safety features in a single platform that can, for example, more safely and efficiently identify and ablate several ventricular tachycardia (VT) locations on the left ventricle of the heart.

Tunneling tools and systems comprising electrodes and tunneling tool. In some examples the tunneling tools have a width that is greater than thickness, or may have enlarged portions to allow tunneling of a space. The tunneling tools may have expandable dissection portions including expandable balloons, linkages and/or springs in different examples. Systems may include tunneling tools with a lumen for receiving a lead having an electrode in a collapsed configuration, where the electrode is designed to expand once placed in a patient, with the tunneling tool designed to create a space in which the electrode can expand.

The present disclosure is a method and apparatus to prepare a tissue tract having a handle member with a centerline, and a scalpel member fixedly attached to the handle member having a blunt tip, wherein the handle member has a first side positioned at a first positive angle relative to the centerline, and a second side opposite the first side positioned at a second positive angle relative to the centerline.

Described are methods and apparatus for use in supporting tissue in a patient's body. In some embodiments, the patient's breast or another tissue is supported. One method involves introducing a superior soft tissue anchor into a patient, the anchor having an inferiorly facing total surface area; and introducing at least one inferior soft tissue anchor into the patient, such that the at least one inferior soft tissue anchor is suspended from the superior soft tissue anchor, the sum of all of the at least one inferior soft tissue anchors having a superiorly facing total surface area. The inferiorly facing total surface area of the superior anchor can be greater, such as at least two times greater than the superiorly facing total surface area of the at least one inferior anchor.

Subcutaneous implantation tools and methods of implanting a subcutaneous device using the same. The tool may include a tool body having a longitudinally extending recess having a distal opening and having a tunneler at a distal end of the tool body extending from the distal opening of the recess. The tool may include a plunger slidably fitting within at least a portion of the tool body recess. The recess may be configured to receive an implantable device and the tunneler preferably extends distally from the recess at a position laterally displaced from the device when the device is so located in the recess. Movement of the plunger distally within the recess advances the device distally out of the recess and alongside of and exterior to the tunneler.
