  • Publication number: 20230061000
    Abstract: A system includes a surgical table, a pad disposed on a table portion of the surgical table, and a leg distraction unit configured for modular attachment to the surgical table, the leg distraction unit configured to apply a distraction force to a leg of the patient while the patient is positioned on the pad and the table portion is tilted so that the patient's head is below the patient's hip, wherein the table portion is capable of tilting to a tilt angle in which the distraction force applied to the leg of the patient is counteracted by a combination of a friction force provided by the pad and a force of gravity from the patient being tilted so that the patient is kept from sliding in a direction of the distraction force.

  • Patent number: 11382816
    Abstract: Embodiments disclosed herein concern a distraction system for use with a surgical table having a table portion and a base portion. The distraction system includes a pair of arms rotatably connectable to the base portion at a proximal end portion of each arm. A pair of telescopically adjustable support posts extend upwardly from corresponding arms. Each arm rotates about a vertically oriented axis to provide for hip adduction and abduction of a patient's leg. Each support post extends from a linear bearing attacked to the corresponding one of the pair of arms for movement along the arm to facilitate applying traction to a patient's leg. The system can also include a table extension attachable to the table portion and a friction pad mounted on the table extension.

  • Patent number: 10624730
    Abstract: Formulations of shape memory polymer (SMP) are integrated with several existing clinically available medical fabrics. The SMP portion of a SMP-integrated fabric can be fabricated in varying thicknesses with the minimum thickness determined by the thickness of the underlying fabric and up to almost any thickness. Integration of the SMP with the base fabrics does not alter the shape memory functionality of the SMP. The design tools for controlling activation rate for traditional SMP materials thus apply to SMP-integrated fabrics. SMP-integrated fabrics may also be steam sterilized without loss of shape memory functionality.

  • Patent number: 10286106
    Abstract: A shape memory polymer (SMP) intraocular lens may have a refractive index above 1.45, a Tg between 10° C. and 60° C., inclusive, de minimis or an absence of glistening, and substantially 100% transmissivity of light in the visible spectrum. The intraocular lens is then rolled at a temperature above Tg of the SMP material. The intraocular device is radially compressed within a die to a diameter of less than or equal to 1.8 mm while maintaining the temperature above Tg. The compressed intraocular lens device may be inserted through an incision less than 2 mm wide in a cornea or sclera or other anatomical structure. The lens can be inserted into the capsular bag, the ciliary sulcus, or other cavity through the incision. The SMP can substantially achieve refractive index values of greater than or equal to 1.45.

  • Publication number: 20180058437
    Abstract: The present invention relates to pumps, particularly a compact, linear, positive displacement pump that can be used in several applications including medical and non-medical devices. In particular, the invention is related to linear, positive displacement compression blood pumps (either intracorporeal or extracorporeal) that provide systemic circulatory stability by maintaining a steady average blood pressure. In some embodiments, the invention relates to perfusion pumps, infusion pumps, pumps used for ECMO (extracorporeal membrane oxygenators) and bioreactor pumps.

  • Patent number: 9808252
    Abstract: Shape memory materials (SMM) are formed as coil-shaped vascular occlusion devices upon deployment. Shape memory polymer (SMP) materials are tailored through formulation for specific mechanical behavior of the coils. Concurrent coil diameter changes enhance the relative change in stiffness along the length of the coil. Interconnecting structures (104a/b) are formed on ends of elongated members (102a) in the pre-deployment shape for multiple coil insertion capability within an introducer. Channels (206) are formed in pre-deployment shape, elongate members (202) that allow access for injection of imaging contrast agent or concurrent placement of instruments. A single SMM occlusive device (300) transforms into multiple, smaller diameter coils (302b) in the deployed state to generate a complex occlusive structure.
