Abstract:
A system for forming an implant to stabilize an interior of a vertebral body is provided. The system includes a delivery cannula (18) in which there is an agglomeration of beads (20) and cement (22). A membrane is disposed over the open end of the cannula. When the agglomeration is discharged from the cannula it fills the membrane. The membrane thus forms the outer shell of the implant internal to the bone.
Abstract:
An implantable neuromodulation system (30) including an electrode array assembly (32) and an implantable pulse generator (34). Signals are wirelessly translated from the implantable pulse generator to the electrode array assembly. A power extractor and supply circuit integral with the electrode array assembly extracts the power from the signals. Instructions contained in the signals are executed by a switch circuit (156) also part of the electrode array assembly for selectively flowing current between selected ones of the electrodes (124) that are part of the assembly.
Abstract:
The present invention provides modified highly potent bone morphogenetic proteins. In particular, the present invention features a chimeric bone morphogenetic protein including a dimer with each monomer containing a type I receptor binding site derived from a member of the BMP subfamily and a type II receptor binding site derived from a member of the TGF-ß subfamily. As a result, the chimeric bone morphogenetic protein has improved binding affinity to type II receptor relative to the naturally-occurring BMP subfamily member from which the type I receptor binding site is derived. Also provided are modified bone morphogenetic proteins having reduced affinity for Noggin. Other embodiments of modified BMPs, compositions and method of use are also included.
Abstract:
A system (100) and method for tracking the three-dimensional position and orientation of a surgical instrument as the instrument (112) is being utilized within the interior of a patient body (102). A stereoscopic camera system (106) generates a stereoscopic image of the patient body which is subsequently rendered on a display device (102). A wireless signal transmitted by an electromagnetic field generator (104) is received by a sensor (114) on the surgical instrument (112). Utilizing this sensor data, a processor (120) calculates the position and orientation of the surgical instrument (112) and then superimposes upon the rendered stereoscopic image of the patient body (102) a graphical representation indicative of the position and orientation of the surgical instrument (112).
Abstract:
A panorama generator (60) for generating a user-defined panorama consisting of a plurality of images generated by different medial and surgical equipment. The panorama generator receives from plural devices that generator images image-defining data. The panorama generator determines if the image-defining data contains data the user wants displayed. If the determination is positive, the panorama generator sizes and positions the data so that the display presents the image in the user-designed location and size on the presented panorama.
Abstract:
A rechargable battery with an internal microcontroller. The microcontroller contains a memory in which data regarding the environment to which the battery is exposed are stored. These data are read by a processor integral with the charger used to charge the battery. If these data indicates the battery may have been subjected to a harsh environment for an excessive period of time, the charger performs a complete state of health evaluation of the battery.
Abstract:
A patient bed includes a base, a patent support supported by the base, and a control system. The patient support includes a pivotal head-end section, with the control system including an actuator to pivot the head-end section and being adapted to control the speed of the actuator and, further, to selectively increase the speed of the actuator to pivot the head-end section at a greater speed.
Abstract:
Various planar, cylindrical, and capillary present electrode assemblies, each having first and second electrodes with dielectrics disposed on or around the electrodes. The electrode assemblies generating a plasma, the plasma acts a destructive sterilizing agent. The electrode assemblies and plasma produced by the electrode assemblies part of a sterilizing system, a system of which, sterilizes medical equipment and other various objects.
Abstract:
A surgical sagittal saw including a handpiece from which a planar guide bar extends. A saw blade is mounted to the distal end of the guide bar to move across the guide bar. Drive rods connect the saw blade to a drive assembly in the handpiece, which drive assembly reciprocates the drive rods. The drive rods oscillate the saw blade across the distal end of the guide bar. The saw is used with a cutting guide that is in a fixed position relative to the bone or hard tissue to be cut. A capture element is disposed adjacent the guide surface and holds the guide bar to the guide surface so the cut is made along the desired cut plane.
Abstract:
An ambulance cot loading and unloading device which utilizes an elongate guide track configured for mounting to a floor surface of a cargo area on the ambulance. A trolley is supported for movement relative to the guide track and has an elongate boom. The ambulance cot has a powered collapsible and extendable base and a patient support deck mounted on the base. A connection mechanism is provided on the trolley and the ambulance cot which is configured to interconnect and securely hold the ambulance cot on the trolley.
