  • Patent number: 11364125
    Abstract: An intramedullary stem prosthesis includes a trunnion tapered in a first direction toward a proximal end of the intramedullary stem, and a conical shaft interfacing with the trunnion at a modular taper junction. The conical shaft is tapered in a second direction toward a distal end of the second component and has a proximal portion, a distal portion, and flutes positioned about a longitudinal axis of the conical shaft and extending along an entire length of the conical shaft and terminating at the modular taper junction such that the flutes intersect the modular taper junction. The proximal portion defines a first taper angle, the distal portion defines a second taper angle greater than the first taper angle, and the flutes define a major diameter of the conical shaft. The major diameter tapers at a major diameter taper angle that is constant along the entire length of the conical shaft.

  • Patent number: 11364113
    Abstract: There is provided herein a bone anchored implant that is used to support a nasal prosthesis in patients with a missing external nose. The implant consists of central section (which is preferably generally triangular) suspended within the aperture of the nasal cavity by four fixation arms which extend radially to engage the surrounding maxillary bone. The triangular portion may support three fixation points, one at each corner of the triangular portion, which in turn, directly engage the nasal prosthesis either via magnets or mechanical locking interface. Extending radially from the triangular section, the four fixation arms may flatten to a clover leaf arrangement of three apertures which accommodate micro-screws that secure the implant to the surrounding maxillary bone.

  • Patent number: 11304808
    Abstract: Patient-specific craniofacial implants structured for filling bone voids or planned bone voids in the cranium and face as well as for simultaneously providing soft tissue reconstruction and/or augmentation for improved aesthetic symmetry and appearance of face and skull. Pterional or temporal voids or defects generally result from a chronic skull or lateral facial deformity along with a compromised temporalis muscle or soft tissue distortion from previous surgery. When muscle and fat atrophy occurs in the pterion or temporal face, temporal hollowing deformity generally results where there would be soft tissue but for the atrophy. The patient-specific craniofacial implants with dual-purpose herein are configured to have an augmented region adjacent the temporal region of the face and cranium in order to prevent and/or correct any such temporal hollowing deformity and to utilize this newfound space to strategically embed implantable neurotechnologies for improved outcomes.

  • Patent number: 11285027
    Abstract: An endovascular apparatus takes the form of an expandable tubular body having a retriever, which may include a pair of interconnected hooks. The retriever may be formed from a single piece of material forming the tubular body, and in the case of a pair of hooks thus has a thickness corresponding to approximately twice the wall thickness of the tubular body. The innermost radial portion of the hooks may be offset from a central axis of a lumen formed by the tubular body, which facilitates free insertion of a balloon or the like for purposes of expanding the tubular body. Related methods of manufacturing an endovascular apparatus with a retriever are also described herein.

  • Patent number: 11253360
    Abstract: Various embodiments of anchors are configured to be inserted into a heart wall of a patient to anchor a suture as an artificial chordae under an appropriate tension for proper valve function. Each of the disclosed anchor embodiments “toggles” from a first position for delivery of the anchor to the heart wall and a second position for insertion of the anchor into the heart wall. In some embodiments, it is the “toggle” to the second position that provides the insertion force for inserting the anchor into the heart muscle sufficient to retain the anchor from accidental withdrawal from the heart wall during normal valve operation (e.g., when a valve leaflet pulls on the suture attached to the anchor during systole). Such anchors are particularly suitable for use in intravascular, transcatheter procedures as described above given the inherent difficulties in providing sufficient force for insertion of an anchor into the heart wall with a flexible catheter.

  • Patent number: 11253380
    Abstract: An absorbable stent includes an absorbable matrix. The matrix includes a number of wave-shaped rings connected by connection units and arranged in an axial direction. The wave-shaped ring includes a number of waves arranged in a circumferential direction. A peak, a valley and a support connecting the peak and the valley form the wave. Two adjacent wave-shaped rings and the connection unit form a closed side supporting unit. The matrix has a volume of [4, 40] ?m per unit blood vessel area. The absorbable stent has sufficient radial supporting strength for clinical applications. Moreover, the volume of the matrix per unit blood vessel area is less than volumes of existing stents. When the absorbable stent and existing stents are made of the same material, the absorbable stent has a shorter degradation and absorption cycle.
