Abstract: A tissue marker is provided having a permanent portion and a biodegradable portion. The permanent portion includes a material detectable by an imaging modality. The biodegradable portion surrounds the permanent portion. The biodegradable portion includes a polymer body, a coating, and a plurality of distinct structures dispersed in the polymer body. The coating covers an outer surface of the polymer body. Each of the distinct structures include an outer shell designed to open upon the application of focused ultrasound to release a therapeutic agent within the outer shell into the polymer body. Therapeutic agents may be introduced into the biodegradable portion of the tissue marker after a period of time after introduction of the tissue marker into the tissue. In addition, methods of fabricating a three-layer tissue marker are provided.

Abstract: Surgical instruments and their methods of use are described. In one embodiment, a surgical instrument includes a power transmission including a trigger and a fastener driver operatively coupled to the trigger. Actuation of the trigger from a first configuration to a second configuration moves the fastener driver between at least a first position and a second position. Additionally, an actuation lockout system operatively associated with the power transmission is moveable between a locked configuration and an unlocked configuration. The actuation lockout system prevents movement of the fastener driver from the first position to the second position when the actuation lockout system is in the locked configuration. Actuation of the trigger from the first configuration towards the second configuration moves the actuation lockout system from the locked configuration to the unlocked configuration.

Abstract: A catheter for actively scoring or slicing a lesion. A catheter body includes first and second lateral openings. A selectively deployable cutter is connected to the catheter body. The cutter has a retracted configuration in which it does not perform a slicing or scoring function, such as while tracking through the vasculature, and a deployed configuration for slicing or scoring an obstruction. The cutter may include a plurality of retractable blades, such that when deployed, each blade projects in a different direction, such as from one of the lateral openings. Related methods are also disclosed.

Abstract: A surgical instrument including a power assist device, and its method of use for deploying surgical fasteners, is disclosed. The surgical instrument may include a handle, an elongated shaft extending from the handle, and a surgical fastener deployment system including a driveshaft. The driveshaft is actuatable between at least a first proximal position and a second distal position. A striker is movable relative to the driveshaft and an impact surface is associated with the driveshaft. The impact surface is constructed and arranged to be struck by the striker member to displace the driveshaft to the second distal position and deploy the surgical fastener.

Abstract: An endovascular implant for forming a fistula includes a body including a wall forming a lumen having a distal opening and a proximal opening. An anchor is coupled to a distal end of the body adjacent the distal opening. The anchor may include a first anchor extending from a first side of a distal end of the body, and a second, separate anchor may extending from a second side of the distal end of the body. A retriever may be coupled to a proximal end of the body adjacent the proximal opening.

Abstract: A method of preparing a filter for delivery into a body vessel. The filter includes a hub disposed along a longitudinal axis and a plurality of anchor members extending from the hub. Each anchor member includes either a cranial extension or a caudal extension at a distal end thereof. At least one anchor member distal end may be spaced from the hub at each of a first, second, and third distance along the longitudinal axis. The filter also includes a plurality of locator members extending from the hub, the locator members alternatingly interposed between the anchor members.

Abstract: A vascular occlusion treatment system includes an ultrasound imaging system having an imaging control circuit communicatively coupled to an ultrasound imaging probe and to a display screen, and an ultrasonic vibration system having an ultrasonic generator operatively coupled to a medical ultrasonic object, such as an ultrasonic catheter. The ultrasonic catheter has a corewire with a distal tip. The ultrasonic generator has a generator control circuit that alternatingly switches between an ultrasonic work frequency and a tracking frequency. The generator control circuit sends a notification to the imaging control circuit when the generator control circuit has switched from the ultrasonic work frequency to the tracking frequency. The imaging control circuit responds by initiating a search in an ultrasound imaging space to locate the distal tip that is vibrating at the tracking frequency, and indicating a location of the distal tip in the ultrasound image displayed on the display screen.

Abstract: A catheter assembly including, in some embodiments, a sonic connector at a proximal end of a core wire, a damping mechanism around a proximal end portion of the core wire, and a heat sink connected to the damping mechanism. The sonic connector is configured to couple to an ultrasound-producing mechanism and transmit vibrational energy to the proximal end of the core wire, which core wire includes a distal end portion configured to modify intravascular lesions. The damping mechanism includes a gasket system around the proximal end portion of the core wire in a damping-mechanism bore of the catheter assembly. The damping mechanism is configured to damp the vibrational energy. A system including, in some embodiments, the catheter assembly and the ultrasound-producing mechanism is also disclosed.

Abstract: In an embodiment, a method of producing a radiopaque stent graft is provided. The method may include functionalizing a surface of a coating layer of a stent graft to produce a functionalized surface; disposing a tie layer over the functionalized exterior surface of the stent graft; disposing an adherent layer over the tie layer; etching a slot into the adherent layer; functionalizing the slot; and positioning a radiopaque marker in the slot to produce a filled slot and thereby produce the radiopaque stent graft.
