The present disclosure provides a medical device and method to determine proper implant screw sizing for inserting within the intramedullary canal of a patient's bone. The medical device includes a radiolucent base that includes radiopaque markings indicative of an implant screw. The markings therefore appear on a radiographic image taken of the provided medical device. The markings may include first diameter markings and length markings, and may also include second diameter markings. The first and second diameter markings may be indicative of a major and minor diameter of an implant screw, respectively. The markings may also include an indication of a type or model of implant screw. In some instances, the medical device may include multiple sets of markings. In such instances, each set of markings is indicative of a different implant screw.

A surgical system for operating on a bone of a patient is described. The surgical system includes a reference device including one or more radiopaque markers, a first sensor configured to generate a first signal pertaining to orientation data of the reference device relative to a first coordinate system, a surgical instrument for coupling to an end effector, a second sensor configured to generate a second signal pertaining to orientation data of at least one of the end effector and the surgical instrument relative to a second coordinate system, and a navigation system. The navigation system is configured to determine an orientation of at least one of the end effector and the surgical instrument and superimpose a virtual representation of at least one of the end effector and the surgical instrument over the image based on the determined orientation and user input.

The invention relates to a marker element for marking body tissue. The marker element has an at least approximately rotation-symmetric geometry about a longitudinal axis, is formed by interlinked, elastic and preformed wire members and can assume a radially compressed and a radially expanded state. The wire members are interlinked at their respective ends, preferably in pairs.

Apparatuses and methods are disclosed for the perforation of a communication between the aorta and left atrium. The method includes introducing the apparatus, positioning the apparatus at a location along the aorta, and energizing the apparatus to create a perforation. For example, one method may include: introducing a flexible wire into the left atrium, advancing a dilator along the flexible wire to position the flexible wire adjacent a selected location along the aorta and energizing the flexible wire to create a perforation from the left atrium into the aorta.

A biopsy site marker includes a carrier, and a marker element. The marker element includes a primary coil, a first anchor and a second anchor. The primary coil is disposed within the carrier. At least a portion of the first anchor and the second anchor extend outwardly from opposite sides of the carrier. The first anchor and second anchor are configured to move relative to the primary coil to engage tissue at a biopsy site.

The present disclosure relates to a method of manufacture of a dental implant for a molar, including acquiring, structural data corresponding to bones of the facial skeleton, the bones of the facial skeleton being proximate the molar, selecting, as a dental implant fixation surface, a surface of the bones based upon a determined thickness of the bones, generating, based on the selected dental implant fixation surface, a contoured surface of the dental implant, and fabricating, based upon an instruction transmitted by processing circuitry, a bone plate extending from a buccal end of a cylindrical plate of the dental implant, the cylindrical plate having support lattices extending therefrom, at least one support lattice of the support lattices being arranged on a lingual end of the cylindrical plate, the cylindrical plate having an opening in a central region thereof, the opening being configured to receive a dental post.

A surgical method treats infections on a lead positioned at least partially within a patient's body. The surgical method includes uncoupling the lead from a pulse generator. The lead is then coupled to an ultrasound wave generator. Ultrasound waves are propagated from the ultrasound wave generator through the lead. Systems are disclosed.

Methods, apparatuses, and systems are described for stent delivery and positioning for transluminal application. The system may include a stent that is disposed coaxially onto an inner tubular member. In some cases, the system may include an outer sheath disposed coaxially along at least a portion of the inner tubular member. The system may include a distal cutting element coupled with a distal end of the inner tubular member and an anchoring component disposed at a distal portion of the inner tubular member. The anchoring component may be configured to retain a distal portion of the stent in place along the inner tubular member as the outer sheath is retracted proximally to deploy the stent, wherein upon retraction of the outer sheath, the stent releases from the anchoring component and expands into a deployed configuration within the body lumen.

The invention relates to a sealing device for repair of cardiac and vascular defects or tissue opening such as a patent foramen ovale (PFO) or shunt in the heart, the vascular system, etc. and particularly provides an occluder device and trans-catheter occluder delivery system. The sealing device would have improved conformity to heart anatomy and be easily deployed, repositioned, and retrieved at the opening site.

A method of reducing blood flow within an aneurysm includes: injecting a contrast agent into a blood vessel including an aneurysm; expanding a stent, from a delivery device, across the aneurysm; and confirming that a stagnated area forms in the aneurysm. The stagnated area can form a crescent shape, a mushroom shape, a hemispherical shape, and/or a flat side. Upon confirming that the stagnated area forms in the aneurysm, the delivery device can be withdrawn from the blood vessel. The stagnated area can include the contrast agent. If the stagnated area does not form in the aneurysm, a second occluding device may be deployed. After withdrawing the delivery device, substantially all of the aneurysm progressively thromboses.
