20140330246 | Intrauterine fetal growth restriction - The biochemical rationale of treatment modalities including extraperitoneal transamniotic fetal supplements - Intrauterine fetal growth restriction (IUGR) is an affliction of a disparaging spectrum, placental insufficiency being the major inciting pathology. The resultant fetal hypoglycemia is alleviated by intravenous hypertonic D-glucose 25-50% maternal supplements, by improving the Vmax of placental transfer for D-glucose, in accordance with Michaelis-Menten model of substrate transfer. Fetal normoglycemia so restored in turn surprisingly improves fetal hypoxia, hypercapnia, hyperlacticemia, acidosis, hypertriglyceridemia, oliguria/hydromnios, and the fetal nutrient/mineral/vitamin acquisition. The list being phenomenal can only convince an inquiring reader by a biochemical sojourn into the aquatic world of the fetus, herein described. Maternal carbohydrate-predominant IUGR diet with maximal amounts of vitamin/mineral supplements are highly beneficial. Transamniotic isotonic D-glucose supplements via minimally invasive suprapubic extraperitonial pelvic approach and amniotomy (Sumathi Paturu's technique), with a subcutaneously implanted pregnancy port (SIPP) catheter is the additional therapy advocated. | 2014-11-06 |

20140330249 | Apparatus and Method for Controlled Depth of Injection into Myocardial Tissue - An injector for delivering an injectate into the myocardium of the heart may be implemented as a catheter or a handheld unit. The injector includes a body, a stabilizer secured to a distal end of the body, and a needle that may be controllably advanced from the distal end of the body. The stabilizer stabilizes the distal end of the body relative to the myocardium while the heart beats. An enlarged region disposed along the needle prevents the needle from being advanced into the myocardium beyond a desired penetration depth. To make an injection, the physician brings the distal end of the body in proximity to the myocardium, actuates the stabilizer to stabilize the distal end relative to the myocardium, and advances the needle into the myocardium. Advancement of the needle is impeded by the enlarged region, thereby placing the needle tip at the desired penetration depth for the injection. | 2014-11-06 |
