  • Publication number: 20180289410
    Abstract: Methods and devices are provided for placing surgical guide pins, reamers, and ligament grafts into bone. In one exemplary embodiment, the method can include advancing a guide pin that includes a proximal rigid portion and a flexible distal portion. The rigid proximal portion can be advanced into a femoral tunnel such that the flexible distal portion extends across an intra-articular space. The flexible portion of the guide pin can be bent to adjust a distance between the guide pin and articular cartilage. A cannulated reamer can be advanced over the flexible portion of the guide pin and the reamer can be manipulated to avoid contact with the articular cartilage in the intra-articular space. A ligament graft can be secured in the femoral tunnel created by the guide pin and the reamer.

  • Patent number: 9814508
    Abstract: Devices and methods are provided for positioning and forming bone tunnels. In one embodiment, a surgical drill guide apparatus is provided. The apparatus can include a first guide member having a longitudinal passageway extending therethrough for aiming a first guide pin along a first path to form a first bone tunnel. The apparatus can also include a second guide member having a longitudinal passageway extending therethrough for aiming a second guide pin along a second path to form a second bone tunnel. The first and second guide members can extend at an angle relative to one another and they can be offset such that axes of the guide members do not intersect.

  • Patent number: 9636017
    Abstract: A modular sensor system is disclosed. The system can include one or more sensors, a mounting unit, and a control unit. The mounting unit can enable the control unit and/or one or more sensors to be securely, but detachably, mounted to a patient's body. The control unit can include electronics and other components configured to interface with, monitor, and record data from the one or more sensors. The control unit can further include a wired bus, transceiver, antenna, or other suitable components to enable wireless communication between the system and a central control or monitor. Some or all of the components included in the control unit can be removable from the system to enable some or all of the electronics of the system to be removed.

  • Patent number: 9498605
    Abstract: A system and method for draining at least one type of bodily fluid from a patient, including a chamber capable of being adjusted to hold one of at least a first volume of fluid and a second, smaller volume of fluid. The chamber has an inlet end with a barrier defining an opening and has an outlet end defining an outlet passage. The system further includes a valve with a valve seat and a valve closure member to define a usable volume within the chamber, and a movable adjustment member with a shaft passable through the opening in the barrier and terminating within the chamber at a first end. The first end of the shaft is connected to the valve seat, and the shaft has a plurality of features along its length engagable with corresponding engagement features in a fixed relationship with the barrier to enable the shaft to be advanced into the chamber to reduce the usable volume to be less than the first volume.

  • Patent number: 7889069
    Abstract: A device and method for monitoring a patient having a sensing device taking sensor data continuously and a transmitter located on the patient and internally powered. The transmitter is normally in a power-down state and powered-up for transmitting the sensor data. A receiver is located remote from the patient and receives the sensor data transmitted wirelessly from the transmitter. The transmission is typically a burst and can also be initiated on a command. For the burst, the sensor data is accumulated over a first period. The transmitter can transmit the sensor data over a second period of time. The second period of time is shorter than the first period of time. Once the transmission is complete, transmitter can be powered down. A further step displays the sensor data at the receiver in pseudo real-time. The display is shifted by a sum of the first and the second period of time.

  • Patent number: 5906234
    Abstract: Methods are provided for producing investment cast articles, such as orthopedic implants or portions thereof, having at least a partially textured surface that is formed during casting of the article. In an exemplary method, a textured metal casting is produced by creating a heat destructible pattern and spraying the pattern with a texturing material to cause the texturing material to form a textured surface on at least a portion of the pattern. In another embodiment, a textured template is pressed against a heat softenable pattern to provide a textured pattern. With respect to each of these methods, a shell is the created around the textured pattern form a mold, and the pattern is removed from the shell. Molten metal is introduced into the mold and allowed to harden, after which the mold is removed. In yet another embodiment a textured pattern for investment casting is provided by creating a textured model and enveloping it with a resilient material to create a resilient mold.
