Catheter with ultrasound-controllable porous membrane

A catheter system for delivering ultrasonic energy and a therapeutic compound to a treatment site within a patient's vasculature comprises a tubular body having an energy delivery section. The catheter system further comprises a fluid delivery lumen extending at least partially through the tubular body. The catheter system further comprises a semi-permeable membrane positioned along a portion of the fluid delivery lumen. The membrane has an increased porosity when exposed to ultrasonic energy. The catheter system further comprises an inner core configured for insertion into the tubular body. The inner core comprises an elongate electrical conductor having a plurality of flattened regions. Each flattened region has a first flat side and a second flat side opposite the first flat side. The inner core further comprises a plurality of ultrasound radiating members mounted in pairs to the flattened regions of the elongate electrical conductor. A first ultrasound radiating member is mounted to the first flat side of the elongate electrical conductor, and a second ultrasound radiating member is mounted to the second flat side of the elongate electrical conductor. The inner core further comprises wiring such that a voltage can be applied from the elongate electrical conductor across the first and second ultrasound radiating members allowing the first and second ultrasound radiating members to be driven simultaneously.

Cytomedicine for preventing intrauterine adhesion and repairing endometrium injury, and preparation method thereof

The invention relates to a cytomedicine for preventing intrauterine adhesion and repairing endometrium injury, and a preparation method thereof. The cytomedicine consists of umbilical cord or placenta mesenchymal stem cells, recombinant human stromal cell-derived factor-1alpha (rhSDF-1alpha), and sodium hyaluronate gel which is used for bearing the umbilical cord or placenta mesenchymal stem cells and the rhSDF-1alpha and has sustained-release and anti-inflammatory effects. When the cytomedicine is injected into a uterine cavity, the curative effects of promoting stem cells and uterus tissue cells to migrate to the injured part, reducing intimal tissue fibrosis, promoting endometrial regeneration and repair, physically obstructing and preventing intrauterine adhesion and the like are achieved. The problems that the stem cells are singly applied to be difficult in local position as well as the traditional intrauterine adhesion and endometrium injury repair method cannot realize serious endometrium injury repair or is short in action time and poor in local curative effect are solved. The preparation provided by the invention is simple in preparation method, easy to implement, safe and effective, and can doubly improve the concentration of the stem cells in the injured part, prolong the action time of the stem cells and improve local curative effect.

Prescription of medicament for treating constipation and preparation method

The invention relates to a prescription of qirong runchang oral liquid and a preparation method thereof. The prescription comprises astragalus root, Cistanche salsa, atractylis ovata, radix pseudostellariae, rehmanniae,figwort, ophiopogon root, angelica, sealwort, mulberry, niger seed, fructus cannabis, brush-cherry seed, bitter orange (bran frying) and honey. The preparation method comprises the following steps of: heating the honey to 116 to 120 DEG C, filtering the honey into the refined honey after boiling, grinding the radix pseudostellariae into the coarse powder, using 60% ethanol for heating reflux to extract for twice with one hour for each time, mixing the extracting solution, filtering, recovering the ethanol from the filtered solution, condensing the ethanol into clear paste with the relative density of 1.02-1.05(50 DEG C), adding water to the dregs of a decoction and the residual medicaments and decocting for twice with two hours for the first time and 1.5 hours for the second time, mixing the decocted solution, filtering, condensing the filtered solution into clear paste with the relative density of 1.10-1.20(50 DEG C), mixing the clear paste with the former one, adding the refined honey, stirring, adjusting the total amount to 1000 ml, stirring, filtering, embedding and sterilizing. The qirong runchang oral liquid can be used for supplementing qi, nourishing yin, invigorating the spleen, nourishing the kidney and relaxing the bowels and can be used for improving debilitation constipation caused by deficiency of both yin and yang, lienorenal deficiency and moist deficiency of large intestines.
