A computer-implemented medical visualization method includes identifying a three-dimensional model of an anatomical item of a particular mammal; displaying a moving animation of the three-dimensional model, the moving animation created from multiple frames from imaging of the anatomical item over a short time period to capture movement of the anatomical item; displaying one or more non-moving views of the three-dimensional model while the moving animation is being displayed; and in response to receiving inputs from a user, changing the displayed moving animation and the one or more non-moving views automatically in coordination with each other.

Comparative analysis of anatomical items

An open-irrigated ablation catheter system includes a catheter body, and an electrode tip body mounted on a distal portion of the catheter body. The electrode tip body includes a proximal end configured for connection to the catheter body and a wall defining an open interior region and including one or more irrigation ports. The wall is conductive for delivering radio frequency (RF) energy. The catheter system further includes a proximal insert positioned partially within the catheter body and at least partially within the proximal end of the electrode tip body. The proximal insert includes a fluid inlet for receiving a cooling fluid delivered via the catheter body. The proximal insert forms a flow path configured to direct the cooling fluid from the fluid inlet to cool the distal portion of the catheter body and to cool a junction of the catheter body and the electrode tip body.

A computer-implemented method for medical device modeling includes accessing an electronic definition for a model of a three-dimensional item and an electronic definition of a three-dimensional spline relating to an internal anatomical volume; determining, with a computer-based finite element analysis system and using the electronic definitions, stresses created by the three-dimensional item along the three-dimensional spline, for different points along the three-dimensional spline; and displaying stress data generated by the finite element analysis system with a visualization system, the display of the stress data indicating levels of stress on portions of the three-dimensional item at particular locations along the three-dimensional spline.

Material analysis of anatomical items

Embodiments herein relate to distributed interactive medical visualization systems with primary/secondary interaction features and related methods. In an embodiment, a distributed interactive medical visualization system is included. The system can include a first video processing circuit and a first central processing circuit in communication with the first video processing circuit. The system can also include a first communications circuit. The system can also include a primary user interface generated by the first video processing circuit. The primary user interface can include a three-dimensional model of at least a portion of a subject's anatomy from a first perspective, the first perspective configured to be controlled by a primary user. The primary user interface can include a command interface object, wherein engagement can cause a secondary user interface to begin mirroring the perspective of the primary user on the three-dimensional model of the subject's anatomy. Other embodiments are also included herein.

Distributed interactive medical visualization system with primary/secondary interaction features

Embodiments herein relate to distributed interactive medical visualization systems including user interface features and related methods. In an embodiment, a distributed interactive medical visualization system is included having a first video processing circuit, a first central processing circuit in communication with the first video processing circuit, a first communications circuit in communication with the first central processing circuit, and a first user interface generated by the first video processing circuit. The first user interface can include a three-dimensional model of at least a portion of a subject's anatomy from a first perspective, the first perspective configured to be controlled by a first user. The first user interface can further include one or more user representations representing one or more other users, the user representations superimposed within the three-dimensional model, wherein each of the one or more user representations are visually distinct from one another. Other embodiments are also included herein.

An implantable medical device includes a housing and a header mounted to the housing, the header including a header body having a bore with an electrical contact located within the bore, wherein the electrical contact includes a helical coil spring having an axial bore, wherein the axial bore of the helical coil spring is aligned with a longitudinal axis of the bore.

Method for making a header contact for an implantable device

A computer-implemented medical visualization method includes identifying a three-dimensional model of an anatomical item of a particular mammal; automatically identifying an open path in three-dimensional space through the anatomical item; fitting a smooth curve to the open path; and displaying the anatomical item and a visual representation of the smooth curve to a user on a three-dimensional imaging system.

Header contact for an implantable device

Some examples of an electrical contact spring for an implantable medical device includes a housing, rigid and tubular in shape, defining a housing passage extending along a longitudinal axis, from a proximal portion including a proximal lip that defines a proximal opening, to a distal portion including a distal lip that defines a distal opening and a spring disposed in the housing, the spring tubular in shape and defining a spring passage concentric to the housing passage, the spring including: a distal ring portion disposed adjacent the distal portion of the housing and physically coupled to the housing, a plurality of spring elements coupled to and extending from the distal ring portion toward the proximal portion of the housing and a proximal ring portion disposed adjacent the proximal portion of the housing, cantilevered and suspended inside of and spaced apart from the housing by the plurality of spring elements.

A lead having an extendable and retractable fixation mechanism has a rotating terminal pin at the terminal end which rotates the fixation mechanism at the distal end. As the terminal pin is rotated, the fixation mechanism is extended or retracted from the distal end of the lead. A threaded collar allows for the fixation mechanism to smoothly extend and retract from the lead, and allows for a 1:1 turn ratio between the terminal pin and the fixation mechanism. A fluoroscopic ring disposed at the distal end of the lead provides information during the implantation process.

A method includes sandblasting an electrode surface, applying a conductive oxide precursor solution to the electrode surface, and heating the electrode for at least 5 minutes at a temperature between 350 degrees C. and 550 degrees C. to convert the precursor solution into an oxide coating. One method includes applying a composite material including a conductive component and a non-conductive component to an electrode and curing the composite material to form a coating on the electrode. One method includes providing a metallic oxide coating on an electrode surface and applying a galvanostatic treatment to the electrode to increase the effective surface area of the metallic oxide coating.
