The invention relates to a device for the reversibly detachable attachment to teeth of an upper jaw or lower jaw, comprising: concave surface regions, each designed for contacting a lateral, in particular buccal, surface region of a tooth to produce a respective positive engagement, the occlusal surfaces of all teeth remaining free so that mastication is not impeded.

The present disclosure relates to a therapy system (100) comprising a radiotherapy device (102) configured to deliver and direct a radiotherapy beam along an axis to a predefined target position (117) in an imagine zone (138, 146) within an MR module (106) of the therapy system (100). The predefined target position (117) is matched with a position of an RF coil (140) of the MR module (106).

This document relates to the apparatus and methods used in the minimally invasive creation of arteriovenous fistula (AVF). In particular, the invention relates to the creation of an AVF using catheters and an alignment methodology that is based upon detection of asymmetric electric fields. The invention finds particular application in vascular access (VA) in the hemodialysis (HD) population.

A surgical stapler comprising an end effector and a system configured to feed staples into the end effector is disclosed.

Systems, methods, and devices are provided for assisting or performing guided interventional procedures using custom templates. The system uses pre-procedure scans of a patient's anatomy to identify targets and critical structures. A template is then manufactured containing guide elements. During a procedure, the template may be aligned to the patient and instruments passed though the guide elements and into various targets. The template may be aligned using one or more of, for example, a position sensing system or a live imaging modality to register the patient to the template. The system makes optional use of devices designed to immobilize or track an organ during therapy.

Provided herein are systems, devices, assemblies, and methods for generating exciter signals, for example, to activate a remotely located tag. The systems, devices, assemblies, and methods find use in a variety of application including medical applications for the locating of a tag in a subject.

Disclosed are medical systems, devices, and methods that support landmarking of a medical device pathway within a patient. A landmarking device that is placed on the patient and coupled with a system module, includes magnetic elements and/or a shape sensing optical fiber to enable determining a position and shape of a landmarking pathway by logic of the system module. A medical device correspondingly includes magnetic elements and/or a shape sensing optical fiber that enable determining an actual pathway of the medical device by logic of the system module during insertion of the medical device. An image of the landmarking pathway combined with an image of the actual pathway are depicted on a display. The logic compares the actual pathway with the landmarking pathway and provides an alert accordingly.

Surgical systems for use in surgical procedures utilizing robotic devices. The surgical system having one or more components for housing a sensor or one or more tools for anchor or sensor delivery. The surgical system may include a surgical sensor anchor and/or a surgical sensor anchor delivery tool. A method of performing a robotically assisted surgical procedure, comprising using a surgical sensor anchor during a surgical procedure which utilizes a robot to track movement of at least one portion of a body structure undergoing a surgical procedure or to track movement of a body structure near a surgical site.

A method for performing a surgical procedure includes planning a resection of a bone of a patient. A volume of the bone is removed according to the planned resection using a surgical tool. As the bone is removed, data corresponding to a shape and volume of the removed bone is tracked with a computer system operatively coupled to the surgical tool. A prosthesis is implanted onto the bone of the patient based on the tracked data corresponding to the shape of the removed bone.

A system may comprise a first catheter having a first steerable segment and a second catheter disposed within the first catheter. The second catheter may have a second steerable segment. The system may also comprise an imaging element supported at a distal end of the second catheter, a coil reference sensor supported at a distal portion of the second catheter, and a processor in electrical communication with the coil reference sensor. The processor may be configured to determine a position of a distal portion of the first catheter with reference to the coil reference sensor.
