A system and method for constructing fluoroscopic-based three dimensional volumetric data from two dimensional fluoroscopic images including a computing device configured to facilitate navigation of a medical device to a target area within a patient and a fluoroscopic imaging device configured to acquire a fluoroscopic video of the target area about a plurality of angles relative to the target area. The computing device is configured to determine a pose of the fluoroscopic imaging device for each frame of the fluoroscopic video and to construct fluoroscopic-based three dimensional volumetric data of the target area in which soft tissue objects are visible using a fast iterative three dimensional construction algorithm.

A dental prosthesis and a process for design and manufacturing, incorporating a dental implant framework and veneering overlay that will be designed and manufactured simultaneously and permanently fixated to one another.

A system for delivering a device into a body lumen of a patient, the system including a device having a marker band and a tube at a proximal portion, and a pusher member having a ribbon and a ball or hook at a distal portion of the delivery member and a compression coil positioned over the ribbon, the ball or hook releasably engageable with the tube.

Catheter-delivered endovascular medical devices are described. The devices may include a pull wire attached to a distal body. The distal body may be formed of a distal body outer body comprising a basket comprised of a plurality of cells defined by a plurality of basket strips and a distal body inner body located in the interior of the distal body outer body and comprising a plurality of distal braided mesh openings formed by a plurality of woven linear strands. The distal braided mesh openings may be smaller than the cells when the device is in the relaxed state. Methods of using and making the devices are also described.

A surgical instrument having a first assembly with a first radio-opaque portion providing a profile of a first portion of an intramedullary implant or canal in a bone, and a second assembly having a second radio-opaque portion providing a profile of a second portion of the intramedullary implant or canal. The surgical instrument may also include a third radio-opaque portion providing an alignment feature to provide a fluoroscopic planar check for the surgical instrument.

Described here are methods and systems for the manipulation of ovarian tissues. The methods and systems may be used in the treatment of polycystic ovary syndrome (PCOS). The systems and methods may be useful in the treatment of infertility associated with PCOS.

A coupling and related methods are disclosed herein that can provide for coupling a first object and a second object with minimal play. A coupling can include a first coupling component having a cylindrical surface with a screw and a pin extending therefrom and a second coupling component having a prismatic surface with a first and a second through-hole. The first coupling component and the second coupling component can be configured such that relative motion between the first coupling component and the second coupling component can be restricted in all six degrees of freedom when the screw is engaged with the first through-hole to secure the cylindrical surface of the first component against the prismatic surface of the second component. The pin can be configured to maintain stability of the coupling and further limit relative movement, such that positioning and/or orientation errors between the first and second components is minimized.

A medical device deployment system includes a main body and a guidewire capable of being passed through the main body and including a lumen. An optical shape sensing (OSS) system is configured to pass through the lumen in the guidewire. The OSS system is configured to measure shape, position or orientation of an endograft relative to a blood vessel for placement of the endograft.

A cover (1) for a shaft of a medical scoping device comprises tubular member (2) arranged for application on the distal tip of the medical scoping device. The cover (1) comprises a plurality of projecting elements (3) spaced apart circumferentially around the tubular member (2), each projecting element having a base portion (13) and an arm portion. The projecting elements are pivotably mounted on the tubular member about a pivot axis. The base portion (13) comprises a detent (20), and the tubular member comprises a contact region, for example a protuberance (23), said contact region being located such that pivoting movement of the projecting element for moving the arm portion in a distal direction can effect impacting of the detent (20) on the contact region (23).

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.
