20090247853 | Non-Invasive Total Hemoglobin Measurement by Spectral Optical Coherence Tomography - Spectral Optical Coherence Tomography (“SOCT”) utilizes Optical Coherence Tomography (“OCT”) to depth-target two or more optical measurements within a blood vessel. OCT achieves depth resolution by the use of optical interferometry.

Depth resolution in the range of 10 μm to 100 μm enables measurements that may be made within more narrow spectral regions (in the range of 1 to 50 nm) in multiple regions of the visible and near infrared spectrum. In one embodiment the light source is configured for three spectral regions centered at 805 nm, 980 nm, and 1050 nm. By comparing the OCT signal at these different spectral positions, the absorption due to tissue and blood analytes may be measured. | 2009-10-01 |

The releasable member is configured such that a force required to remove the distal end of the releasable member from engagement with the engagement surface of the syringe body is greater than the force required to disengage the proximal end of the releasable member from the sealing member throughbore. As such, upon movement of the sealing member from the advanced position to the retracted position, the proximal end of the releasable member is disengaged from the sealing member throughbore to unseal the throughbore. | 2009-10-01 |
20090247950 | CONTINUOUS DRUG SOLUTION INFUSION DEVICE - A continuous drug solution infusion device is provided that is capable of administering a drug solution into a patient's body for a predetermined period of time substantially at a predetermined flow rate from the beginning to end of the drug solution infusion by suppressing the change in pressure from the beginning to end of the infusion. The continuous drug solution infusion device has at least two tubular members disposed in series along an infusion path for a drug solution and at least one expandable/contractible tubular member disposed between the tubular members. | 2009-10-01 |
20090247951 | INJECTION DEVICE COMPRISING LOW-LOSS DRIVE - An injection device including a housing, a delivery element displaceable in relation to the housing, and at least one ball bearing which absorbs forces transmitted between the delivery element and the housing, transmits axial forces from the delivery element to the housing, and is located in a front region of the injection device. | 2009-10-01 |
