A simplified contrast agent configuration is provided where an appropriate contrast agent detection technique and/or contrast agent imaging parameters are achieved consistently and more often then exists with current methods. Examination workflow is improved for contrast agent studies by offering one contrast agent imaging mode or configuration that is dynamically determined and optimized based on the user's selected transmit level and/or a real-time measurement of the contrast agent signals. A simplified user interface provides one contrast agent imaging mode without a need to switch between multiple modes or contrast agent detection techniques and associated contrast agent imaging parameters. The contrast agent detection technique and imaging parameters are adjusting or selected based on changes in the transmit levels for contrast agent imaging. Either a single user input control or real time measurements are used to select a transmit level, resulting in automatic selection of adjustment of the detection technique and/or imaging parameters. Appropriate contrast agent detection techniques and imaging parameters are selected for each given transmit level without the user having to switch the mode or configuration of the system during an imaging session.

| 20110263974 | METHOD FOR PRESSURE MEDIATED SELECTIVE DELIVERY OF THERAPEUTIC SUBSTANCES AND CANNULA - Methods and devices are disclosed for selective delivery of therapeutic substances to specific histologic or microanatomic areas of organs. Introduction of the therapeutic substance into a hollow organ space (such as an hepatobiliary duct or the gallbladder lumen) at a controlled pressure, volume or rate allows the substance to reach a predetermined cellular layer (such as the ephithelium or sub-epithelial space). The volume or flow rate of the substance can be controlled so that the intralumenal pressure reaches a predetermined threshold level beyond which subsequent subepithelial delivery of the substance occurs. Alternatively, a lower pressure is selected that does not exceed the threshold level, so that delivery occurs substantially only to the epithelial layer. Such site specific delivery of therapeutic agents permits localized delivery of substances (for example to the interstitial tissue of an organ) in concentrations that may otherwise produce systemic toxicity. Occlusion of venous or lymphatic drainage from the organ can also help prevent systemic administration of therapeutic substances, and increase selective delivery to superficial epithelial cellular layers. Delivery of genetic vectors can also be better targeted to cells where gene expression is desired. The access device comprises a cannula with a wall piercing tracar within the lumen.

| 20160375227 | GUIDEWIRE WITH ADJUSTABLE STIFFNESS - A medical guidewire system including an inner member having an outer diameter and an outer member having an inner diameter, the inner diameter being larger than the outer diameter. The inner and outer members are relatively slidable to adjust a stiffness of the guidewire system. The lumen of the outer member forms a gap for fluid flow therethrough. A connector to the inner member and a fluid infusion channel communicating with the gap for injection of fluid through the gap to exit a distal portion of the outer member. | 12-29-2016 |
| 20160375234 | TRANSPAPILLARY METHODS AND COMPOSITIONS FOR DIAGNOSING AND TREATING BREAST CONDITIONS - Methods and treatments are taught for the diagnosis and treatment of breast conditions, including proliferative breast disease, ductal hyperplasia, lobular hyperplasia, atypical ductal hyperplasia, atypical lobular hyperplasia, ductal carcinoma in situ, lobular carcinoma in situ, lobular carcinoma and invasive breast cancer. The methods and compositions deliver efficacious formulations of chemical and/or biological treatment medicaments to the breast via a transpapillary route. | 12-29-2016 |
