Abstract: A system for replacing a tibial side of patient's ankle joint, wherein the tibial side of the ankle joint includes a tibia having a medullary cavity. The system includes a tibial implant having a stem component and a base component; one or more tools for preparing the tibia for installation of the tibial implant; and one or more instruments for installing the tibial implant into a prepared tibial surface.

Abstract: The present disclosure generally discloses instruments and methods of using those instruments for performing various aspects of ankle replacement surgery. In one embodiment, an alignment assembly for adjusting a position of a guide tool relative to a patient is provided. The alignment assembly includes a proximal housing; a distal housing configured to be connected to the guide tool; and at least one linkage system configured to adjust a relative angle between at least two portions of the alignment assembly. A surgical guide wire is also disclosed. The surgical guide wire includes a distal tip having a tapered or trocar end configured for insertion into a bone; a distal region adjacent to the distal tip; a transition region adjacent to the distal region; and a proximal region adjacent to the transition region.

Abstract: Provided herein are 3D-printed patient-specific surgical guides and methods for making and using the same. In at least one embodiment, the guides include a first and second end, a first and second side, a conformal bone engaging surface, a front surface, one or more porous regions, one or more walls, and a plurality of openings. At least one of the plurality of openings extends through the guide between the conformal bone engaging surface and the front surface. The conformal bone engaging surface is contoured to a patient's anatomy. The first and second end, and the first and second side are contoured to avoid soft tissues of the patient.

Abstract: A method of detecting and mitigating kickback in a saw includes identification of a running average speed (RPM) of a saw blade, the speed at a given time sample relative to the running average speed, the percentage change in speed from one speed sample to the previous speed sample, and the percentage change in average speed based on the current speed of the saw blade. If the identified speed profile from the samples indicates a kickback is imminent, then the saw identifies an imminent kickback event and removes power from the saw motor to mitigate kickback.

Abstract: Embodiments of the present disclosure relate to treating diseased tissue with ablation therapy. In an embodiment, an apparatus comprises a catheter having an elongate body extending between a proximal end and a distal end. The apparatus further includes a balloon structure arranged proximal to the distal end of the catheter, wherein the balloon structure has a first portion with a first permeability and a second portion with a second permeability such that the first permeability is different than the second permeability. In addition, the apparatus includes a first electrode arranged on or within the balloon structure and configured to: transmit current through the first portion, receive current transmitted through the first portion or both.

Abstract: An ankle prosthesis implant is disclosed herein. The ankle prosthesis implant includes a talar implant defining a superior bearing surface. The superior bearing surface includes a convex portion and a concave portion. The convex portion is defined in an anterior-posterior direction when viewed from a sagittal plane and has a neutral axis (X1) defined in a coronal plane at an anterior-posterior midline of the talar implant and extending in a medial-lateral direction. The concave portion is defined in the medial-lateral direction when viewed from the coronal plane, and the concave portion is swept about a secondary axis (X2) that is angled relative to the neutral axis (X1) upwards towards a medial end of the talar implant by an angle (?).
