Methods for use in dental articulation

A computer implemented method of creating a dental model for use in dental articulation includes providing a first set of digital data corresponding to an upper arch image of at least a portion of an upper dental arch of a patient, providing a second set of digital data corresponding to a lower arch image of at least a portion of a lower dental arch of the patient, and providing hinge axis data representative of the spatial orientation of at least one of the upper and lower dental arches relative to a condylar axis of the patient. A reference hinge axis is created relative to the upper and lower arch images based on the hinge axis data. Further, the method may include bite alignment data for use in aligning the lower and upper arch images. Yet further, the method may include providing data associated with condyle geometry of the patient, so as to provide limitations on the movement of at least the lower arch image when the arch images are displayed. Further, a wobbling technique may be used to determine an occlusal position of the lower and upper dental arches. Various computer implemented methods of dental articulation are also described. For example, such dental articulation methods may include moving at least one of the upper and lower arch images to simulate relative movement of one of the upper and lower dental arches of the patient, may include displaying another image with the upper and lower dental arches of the dental articulation model, and/or may include playing back recorded motion of a patient's mandible using the dental articulation model.

Removable wound closure

A system and method for the temporary closure of a wound, especially an abdominal wound, to facilitate re-entry, final closure, and long term healing of the wound. An abdominal wound dressing and methods of use are described that enable the application of negative pressure to the wound site in a site healing promoting manner while also limiting the formation of adhesions that would prevent the removal of the dressing. The dressing comprises a layer of porous foam material (36) enclosed by sheets of elastomeric material (38) punctuated by a number of appropriately placed holes (34). Multiple layers of porous foam may also be used. A suction tube connector (16) is provided on an upper surface of a layer of foam (12) for connection to a negative pressure source. At least one layer of foam is enclosed in elastomeric material and is placed in direct contact with the tissue within the open wound. Fluids are drawn by negative pressure through the holes positioned in the elastomeric envelope, and through the foam. If multiple foam layers are employed, the lower layer(s) of foam are of a finer porosity while the upper layer of foam is coarse. An adhesive elastomeric sheet (14) covers the entire wound dressing and seals the edges to the skin surrounding the wound. An appropriate vacuum device is attached to the suction tube connector.

Spine stabilization systems and associated devices, assemblies and methods

A system and method for effecting multi-level spine stabilization is provided. The system includes a plurality of pedicle screws which are joined relative to each other by elongated members, e.g., rods. At least one of the rods includes a dynamic stabilizing member. The pedicle screw junctions are dynamic, i.e., free relative movement of a socket member is permitted relative to a fixed spherical element. Placement of the spherical element may be facilitated using a guidewire system that includes a guidewire and a tapered guide member. A spine stabilization assembly is also provided that includes an attachment member that includes an opening. At least one spherical element that includes a rod-receiving channel is movably mounted within the opening with three degrees of rotational freedom. The spherical element generally defines an elliptical rod-receiving channel that is deformable to a circular opening to firmly engage a rod positioned therein. Multi-level stabilization systems that combine / mix dynamic and non-dynamic stabilization modalities are also provided. The multi-level spine stabilization system offers efficacious clinical results at least in part due to the inclusion of dynamic stabilizing member(s).

Surgical instrument with detection sensors

Aspects of the present disclosure are presented for a surgical instrument having one or more sensors at or a near an end effector and configured to aide in the detection of tissues and other materials and structures at a surgical site. The detections may then be used to aide in the placement of the end effector and to confirm which objects to operate on, or alternatively, to avoid. Examples of sensors include laser sensors used to employ Doppler shift principles to detect movement of objects at the surgical site, such as blood cells; resistance sensors to detect the presence of metal; monochromatic light sources that allow for different levels of absorption from different types of substances present at the surgical site, and near infrared spectrometers with small form factors.

Microfluidic particle-analysis systems

The invention provides systems, including apparatus, methods, and kits, for the microfluidic manipulation and/or detection of particles, such as cells and/or beads. The invention provides systems, including apparatus, methods, and kits, for the microfluidic manipulation and/or analysis of particles, such as cells, viruses, organelles, beads, and/or vesicles. The invention also provides microfluidic mechanisms for carrying out these manipulations and analyses. These mechanisms may enable controlled input, movement/positioning, retention/localization, treatment, measurement, release, and/or output of particles. Furthermore, these mechanisms may be combined in any suitable order and/or employed for any suitable number of times within a system. Accordingly, these combinations may allow particles to be sorted, cultured, mixed, treated, and/or assayed, among others, as single particles, mixed groups of particles, arrays of particles, heterogeneous particle sets, and/or homogeneous particle sets, among others, in series and/or in parallel. In addition, these combinations may enable microfluidic systems to be reused. Furthermore, these combinations may allow the response of particles to treatment to be measured on a shorter time scale than was previously possible. Therefore, systems of the invention may allow a broad range of cell and particle assays, such as drug screens, cell characterizations, research studies, and/or clinical analyses, among others, to be scaled down to microfluidic size. Such scaled-down assays may use less sample and reagent, may be less labor intensive, and/or may be more informative than comparable macrofluidic assays.

Systems and methods for displaying changes in biological responses to therapy

Systems and methods of this invention display data using pixels with information indicated by color and intensity changes, particularly used for monitoring of physiological variables in real time. For certain methods, physiological data can be acquired by sensors, acquired data can be stored in data frames, data frames can be processed using computer-implemented methods, and processed data frames can be scaled to a display frame for display on a display device. Using such methods, a spot made up of a group of pixels can be updated during a time frame, or cycle using a computer-implemented method, such as addition, subtraction, multiplication, division or a time dependent function. Newly received data can be combined with prior received data to indicate time-dependent changes. In this way, each spot contains a cumulative history of data starting at some initial time. In other embodiments, visual contrast can be enhanced between desired data and other data. In further embodiments, two or more different types of data can be plotted together to indicate relationships between variables. Real time monitoring of signals during therapeutic treatment using light, electricity or other nerve or muscle stimuli can allow a user to monitor physiological responses during stimulation and to make rapid decisions about medical treatment.

Biodegradable vehicle and filler

A biodegradable vehicle and filler (referred to in this invention as biodegradable vehicle), which can be mixed with one or more biologically active substances (BAS), or can be used as a biodegradable filler to fill in cavities or body tissues in animals, birds and humans. The consistency and rheology, hydrophilicity and hydrophobicity, and in vivo degradation rates of the biodegradable vehicle is controlled by modulating the molecular weight of polymers and copolymers, concentration of plasticizers, ratios of two or more plasticizer in the blends, types of polymers and copolymers, copolymer ratios, and ratios of blends of polymers with different molecular weights or different copolymers. The biodegradable vehicle is mixed with one or more BAS (which is separately stored away from the biodegradable vehicle in an appropriate container) just prior to use. Mixing of the BAS with the biodegradable vehicle can be accomplished by simply stirring the mixture with a stirring device, or by triturating the mixture or employing an ointment mill or a suitable device or apparatus or equipment that can be used for blending / mixing. Alternatively, a device, which resembles two syringes, attached together with a removable partition or a valve assembly can also be used to uniformly mix the BAS with the biodegradable vehicle. The mixing is performed in order to dissolve or uniformly suspend the BAS particles in the biodegradable vehicle. Modulating the polymer to plasticizer ratio, polymer molecular weight, copolymer ratio, and hydrophobicity and hydrophilicity of the plasticizer controls the release of the BAS from the biodegradable vehicle.
