A method for performing a cranioplasty includes the steps of prefabricating a sonolucent craniofacial implant based upon information generated by preoperative scans, creating a cranial, craniofacial, and/or facial defect, and attaching the craniofacial implant to the cranial, craniofacial, and/or facial defect. The craniofacial implant is composed of a material that is sonolucent and exhibits attenuation of less than 6 dB/cm.

A biopsy device includes a housing containing an electric power source and a tension slide, wherein the tension slide is configured to be moved to a cocked position against the action of a first spring. A releasable locking mechanism is configured to lock the tension slide in the cocked position. A removable element is configured for insertion into the housing. The removable element has a cutting sheath configured to couple the electric power source to the tension slide. The electric power source is configured to rotate the cutting sheath to move the tension slide to the cocked position.

A delivery system for delivering a drug depot to a site within a patient, the system comprising: a cannula; a delivery stylet configured and dimensioned to be receivable by and slidable forwardly and backwardly within the cannula including to a position wherein a distal portion of the stylet protrudes beyond the distal end of the cannula; a drug depot retainable by the stylet at the distal end of the stylet, the drug depot being visualizable by a diagnostic imaging beam or modality; and an actuator for ejecting the drug depot from the stylet to a site within the body using fluid pressure. Also disclosed are methods using, and uses of, the delivery system, including for treating scoliosis.

The present invention provides fixation devices, locking assemblies, and methods for using the same. The fixation devices of the invention are capable of accurate insertion of medical devices by providing detection means of a patient's internal anatomy and localizing a desired target. The devices are capable of locking into position to maintain accuracy.

A method of cutting soft tissue in a hand to treat trigger finger involves advancing an introducer shaft into the hand to position a distal end of the introducer shaft beyond a pulley in a finger of the hand, advancing a blade along a guiding channel on an upper surface of the introducer shaft, to position a distal end of the blade at or near the distal end of the introducer shaft, and rotating a cutting surface of the blade to an orientation at or near perpendicular relative to the upper surface of the introducer shaft. The method further involves retracting the blade along the introducer shaft to cut the pulley and removing the introducer shaft and the blade from the hand.

A safety introducer needle assembly having an introducer needle defining an axial direction, the needle having an outer surface and an inner surface defining a lumen which extends along the length of the needle in the axial direction; the outer surface defined by a wall of the needle forming a needle shaft that extend along the axial direction having a distal end and a proximal end, wherein the proximal end connected to a needle hub and the distal end comprising a sharp bevelled tip wherein the needle has a roughened or echogenic region having echogenic features; and a needle tip protector housed in a safety barrel and slidably arranged on the needle shaft from moving beyond the needle tip and wherein the safety barrel is engageably attached to the needle hub.

The present application provides an ablation catheter (100) and an ablation device. The ablation catheter (100) includes a catheter assembly (10) and an ultrasonic generator (20) arranged in the catheter assembly, wherein the ultrasonic generator includes a driving assembly (21) and a generation assembly (22) connected to the driving assembly, the driving assembly is configured for driving the generation assembly to vibrate, the generation assembly is configured for emitting ultrasonic waves and converging the ultrasonic waves to a focus, and the focus is located out of the catheter assembly. The ablation device includes the above ablation catheter.

A device for treating de Quervain's tenosynovitis may include a handle, an introducer shaft extending from the handle, and a blade that includes a blade shaft extending along a top surface of the introducer shaft and onto the handle and a blade cutting edge that faces toward the handle. The device may further include a blade slider attached to a proximal portion of the blade shaft, a blade pivot attached to at least one of the proximal portion of the blade shaft or the blade slider, an upper deck along which the blade slider slides in an upper horizontal orientation, and a lower deck along which the blade slider slides in a lower horizontal orientation. The blade pivot is configured to allow the blade slider to rotate in a plane that is perpendicular to a plane of the introducer shaft.
