A method of repairing soft tissue and other surgical devices are also disclosed. | 09-25-2008 |
| 20080234714 | Cutting Tool Having A Magnetically Controlled Pre-Load Force - The present disclosure relates to a cutting tool that includes an outer tubular member having a first magnet and an inner tubular member having a second magnet wherein the inner tubular member is slidably disposed within the outer tubular member. A force, such as an attractive force, is created between the first magnet and the second magnet. The attractive force creates a preload force between the inner tubular member and the outer tubular member. A method of creating a force between an inner and outer tubular member is also disclosed. | 09-25-2008 |
| 20080214990 | Fluid Conduit Connection - A fluid conduit connector assembly includes a connector having a body with an inner surface defining a fluid channel. The connector also includes an inlet region for flow of fluid into the fluid channel, and an outlet region for flow of fluid from the fluid channel. The connector further includes an axial alignment member outward of the body, and a pair of flexible tabs arranged generally circumferentially of the alignment member and outward of the body. The connector can be configured as a day-side connector, transfer member with check valve, and/or patient-side connector. An implementation includes a day-side connector, a patient-side connector, and a transfer member, each of which has a pair of flexible tabs. The pairs of tabs are configured such that the transfer member releasably couples the day-side and patient-side connectors. A method for aseptically connecting a fluid conduit is also disclosed. | 09-04-2008 |
| 20080208516 | Cycle and Load Measurement Device - The present application relates to a sensing system for an medical device, the sensing system having at least one sensor for measuring movement of the medical device and a recording device for storing movement data from the at least one sensor. The application also relates to a method for evaluating a patient' s compliance with a healing regimen, the patient provided with a medical device, the method having the steps of a) collecting movement data relating to movement of a sensing system affixed within, to, or near the medical device; b) retrieving the movement data from the sensing system; and c) analyzing the movement data and comparing the movement data to standard movement data to evaluate the patient's compliance with the healing regimen. | 08-28-2008 |
| 20080208081 | System and Method For Determining Tibial Rotation - A system and method for determining tibial rotation is disclosed. The system includes a first fiducial, a second fiducial, a position and orientation sensor, a computer, and a monitor. The first fiducial is connected to a first part, and the second fiducial is connected to a second part. The position and orientation sensor tracks the first fiducial and the second fiducial. The computer has a memory, a processor, and an input/output device. The input/output device receives data from the position and orientation sensor. The processor processes the data to identify a first axis of the first part and a second axis of the second part. The processor constructs a reference plane through the second axis and orthogonal to the first axis. The monitor is connected to the input/output device and displays a rendering of the reference plane. | 08-28-2008 |
