The disclosure relates to an implantable woven graft for bridging a defect in a main vessel near one or more branch vessels. The graft includes a region of reduced density. Reduced density regions are alignable with at least one of the one or more branch vessels, and are suitable for in situ fenestration, for example by perforation. The disclosed examples are particularly suited for bridging abdominal aortic aneurysms.
摘要:
An intervertebral implant device, including: a pair of substantially parallel opposed arcuate surfaces; a pair of substantially parallel opposed frictional surfaces each including a plurality of raised structures; a substantially curved end wall joining the pair of parallel opposed arcuate surfaces; and a substantially recessed end wall joining the pair of parallel opposed arcuate surfaces; wherein the intervertebral implant device defines one or more voids in which a bone graft material is selectively disposed. Preferably, the substantially recessed end wall is configured to selectively and pivotably receive one or more surgical implantation devices.

A toy includes a base member and coupling member. In one embodiment, the base member has, for example, three attachment posts. The coupling member is configured to be removably coupled to any one of the attachment posts. The coupling member is also configured to be removably coupled among the three attachment posts. In one embodiment, the coupling member includes three projections that define a receiving portion. The receiving portion is configured to receive at least a portion of any one of the attachment posts. The projections of the coupling member are configured to be coupled among the three attachment posts. In another embodiment, the base member includes a prearranged play area that has a spherical portion, a cylindrical portion, and a wall portion. The coupling member is configured to be removably coupled to the spherical portion, the cylindrical portion, and the wall portion of the base member. In another embodiment, the coupling member includes an entertainment feature, such as, for example, a figure.

The present invention provides a minimally invasive surgery pedicle screw system, including: a plurality of slotted guides that are selectively inserted through one or more surgical incisions; a plurality of pedicle screws selectively coupled to the plurality of slotted guides that are selectively secured to one or more bony anatomical structures; a pendulum mechanism selectively translatably and pivotably coupled to one of the plurality of slotted guides; and a connecting rod selectively translatably and pivotably coupled to one of the plurality of slotted guides; wherein the pendulum mechanism is selectively coupled to the connecting rod. The connecting rod is selectively secured to one or more of the plurality of pedicle screws.
摘要:
The present disclosure provides a cannulated bone screw system including a screw with a threaded portion, a non-threaded portion, and a first plurality of teeth spaced apart from a screw head; and a washer with an interior portion with a second plurality of teeth and an opening and an outer portion with a plurality of spikes. The first plurality of teeth are on an inferior convex surface; wherein the second plurality of teeth are on a superior concave surface; and wherein the first plurality of teeth and the second plurality of teeth are operable to mate to prevent the screw from backing out of the washer while allowing the cannulated bone screw system to conform/pivot in order to accommodate different bone morphologies.
摘要:
A method of analysing controlled source electromagnetic (CSEM) survey data to determine probability density functions (PDFs) for values of an electromagnetic parameter at locations in a subterranean region of interest is provided. Structural features in the subterranean strata are identified, e.g. from seismic survey data. An initial PDF for values of the electromagnetic parameter is then assigned to each feature. Models lo specifying values for the parameter in each structural feature are generated by sampling the PDFs. A subset of the models are deemed acceptable based on an acceptance criterion. The PDF for each feature is modified based on values for the parameter in the subset of accepted models to generate replacement PDFs for each feature. The process may be iterated a number of times to generate final PDFs for values of the electromagnetic parameter in the structural features identified in the subterranean region of interest.
