  • Patent number: 9907590
    Abstract: Systems, devices, and methods for longitudinal closure of a dissected sternum are provided. The system includes first and second reinforcing members, fasteners, and closure members. Each reinforcing member is configured to be placed on an outer surface of a respective sternum portion, such that each reinforcing member is longitudinally disposed on an opposite side of a sternum opening with respect to the other reinforcing member. Fasteners may be placed in holes defined in the reinforcing members to secure a respective reinforcing member to a corresponding sternum portion. The closure members, which may be sternal closing wires, may then be wrapped around the sternum portions and the reinforcing members transversely to close the sternum opening. Because the reinforcing members include extended regions having lateral edges that extend away from a midline of the respective reinforcing member, the closure members are moved away from the edges of the bone.

  • Patent number: 9724357
    Abstract: Provided are methods for maintaining the viability of photoreceptor cells following retinal detachment. The viability of photoreceptor cells can be preserved by administering a hydrophilic bile acid (e.g., UDCA or TUDCA) to a mammal having an eye with a detached retina. Administration of the hydrophilic bile acid maintains the viability of the photoreceptor cells until such time that the retina becomes reattached to the underlying retinal pigment epithelium and choroid, thereby minimizing the loss of vision or visual acuity, which otherwise may occur as a result of the retinal detachment.

  • Patent number: 9675329
    Abstract: An articulating surgical instrument includes a case having a trigger handle, a sheath coupled to the case, a flexible bending section coupled to the sheath, an end effector removably attachable to the bending section, a set of cables that control position of the bending section, at least two motors coupled to the cables, and a user control module configured to control position of the bending section and the end effector. The instrument further includes a pushrod disposed within the sheath and within the bending section that is configured for axial motion relative to the sheath and the bending section and rotational motion within the sheath and the bending section. The pushrod is coupled to the trigger handle and removably coupled to the end effector, so that rotational motion of the pushrod effectuates rotation of the end effector and axial motion of the pushrod is controllable by the trigger handle.

  • Patent number: 9668721
    Abstract: A surgical apparatus for positioning within a tissue tract accessing an underlying body cavity adapts to tissue tracts of different widths. The surgical instrument includes a proximal member, a distal member, and a sleeve extending between the proximal member and the distal member and defining a longitudinal passage therein. The proximal member includes an inflatable member that selectively adjusts the radial dimension of the proximal member. A ring member may be separately insertable by a user during a surgical procedure into the space directly adjacent to the radially-inner surface of the inflatable member, so as to selectively provide rigidity to the proximal member.
