20090264753 | METHOD & SYSTEM FOR MULTI-MODALITY IMAGING OF SEQUENTIALLY OBTAINED PSEUDO-STEADY STATE DATA - Methods, protocols and systems are provided for multi-modality imaging based on pharmacokinetics of an imaging agent. An imaging agent is introduced into a subject, and is permitted to collect generally in a region of interest (ROI) in the subject until attaining a pseudo-steady state (PSS) distribution within the ROI. The imaging agent records a first functional state of the ROI at a given point in time. A first image data set is obtained with a first imaging modality during a first acquisition time interval that occurs prior or proximate in time with the PSS time interval. The subject is transferred from the first imaging modality to a second imaging modality during a transfer time interval that overlaps the PSS time interval. Once transfer is complete, a second image data set is obtained with the second imaging modality during a second acquisition time interval that also overlaps the PSS time interval in which the imaging agent maintains the PSS distribution in the ROI. In accordance with a protocol, the transfer time interval and second acquisition time interval substantially fall within the PSS time interval. The imaging agent collects in the ROI during an uptake time interval which may or may not precede the time interval during which first imaging modality obtains at least a portion of the first image data set. The second image data set is obtained while the imaging agent persists in the ROI at the PSS distribution reflective of the first functional state even after the ROI is no longer in the first functional state. | 2009-10-22 |
20090264754 | METHOD AND APPARATUS FOR EVALUATING OSTEOINTEGRATION OF MEDICAL IMPLANTS - Ultrasound vibrometry is employed to determine the amount of bony in-growth (i.e., osteointegration) into a surgically implanted prosthetic component (or conversely, the degree of implant looseness). While specifically developed for assessing osteointegration for total ankle replacements, the technique has broader application to any joint arthroplasty device. With respect to ankle arthroplasty, a vibration is induced in a patient's ankle in a range of frequencies. A Doppler ultrasound unit scans the ankle, with an imaging plane focused on an implant surface. The vibrations input into the ankle are sinusoidal frequencies, in a range from 80-500 Hz. At a frequency determined to best facilitate vibration of the ankle (e.g., a resonant frequency), the output signal from the Doppler ultrasound is Fourier transformed so that the frequency components of the output signal can be observed. These output Fourier signatures have been shown to correspond to a graded response of implant osteointegration (or looseness). | 2009-10-22 |

20090264827 | METHODS OF IMPLANTING AN INJECTION PORT - A surgical fastening system for implantable devices is disclosed. The implantable device may contain a plurality of fasteners in pre-deployment position, may have a housing fitted over or around fit which contains a plurality of fasteners in pre-deployment position, or may be a part of a two-part system into which it fits. Accordingly, the present invention also encompasses a deployment system or tool that optionally positions the implantable device, and which causes the fasteners to move into post-deployment position. The fasteners may be staples, metal loops, coils, springs or hooks formed of biocompatible materials, including shape memory alloys such as NiTi. | 2009-10-22 |
20090264828 | Drug Delivery Device Dose Setting Mechanism - A method and system for proving a drug delivery device. The device comprises a drug delivery device housing and a medicament contained in the drug delivery device housing. A dose dial sleeve is positioned in the housing and is rotatable to set a non-inverted dose of the medicament contained in the medical delivery device. The non-inverted dose may be increased by turning the dose dial sleeve in a direction towards a user of the drug delivery device. The dose medicament may be decreased by rotating the dose dial sleeve in a direction away from the user. | 2009-10-22 |
