Publication number: 20180289410Abstract: 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.Type: ApplicationFiled: June 12, 2018Publication date: October 11, 2018Applicant: DePuy Mitek, LLCInventor: Douglas A.

Patent number: 9636017Abstract: 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.

Patent number: 9498605Abstract: 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.Type: GrantFiled: March 31, 2014Date of Patent: November 22, 2016Assignee: DEPUY SYNTHES PRODUCTS, INC.Inventors: Douglas Fifolt, Carl Turgeon, Thomas Boden, Jr.

Patent number: 7889069Abstract: 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.Type: GrantFiled: April 1, 2005Date of Patent: February 15, 2011Assignee: Codman & Shurtleff, Inc.Inventors: Douglas A.

Patent number: 5906234Abstract: 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.Type: GrantFiled: October 22, 1996Date of Patent: May 25, 1999Assignee: Johnson & Johnson Professional, Inc.Inventors: Brooke W.
