Protein stabilized pharmacologically active agents, methods for the preparation thereof and methods for the use thereof
InactiveUS6749868B1Low toxicityLong half-lifePowder deliveryEchographic/ultrasound-imaging preparationsSuspended particlesFree protein
In accordance with the present invention, there are provided compositions and methods useful for the in vivo delivery of substantially water insoluble pharmacologically active agents (such as the anticancer drug paclitaxel) in which the pharmacologically active agent is delivered in the form of suspended particles coated with protein (which acts as a stabilizing agent). In particular, protein and pharmacologically active agent in a biocompatible dispersing medium are subjected to high shear, in the absence of any conventional surfactants, and also in the absence of any polymeric core material for the particles. The procedure yields particles with a diameter of less than about 1 micron. The use of specific composition and preparation conditions (e.g., addition of a polar solvent to the organic phase), and careful election of the proper organic phase and phase fraction, enables the reproducible production of unusually small nanoparticles of less than 200 nm diameter, which can be sterile-filtered. The particulate system produced according to the invention can be converted into a redispersible dry powder comprising nanoparticles of water-insoluble drug coated with a protein, and free protein to which molecules of the pharmacological agent are bound. This results in a unique delivery system, in which part of the pharmacologically active agent is readily bioavailable (in the form of molecules bound to the protein), and part of the agent is present within particles without any polymeric matrix therein.

Stent and process for producing the same
A stent comprising a tubular stent matrix of which diameter is extendable and a flexible polymer layer covering the stent matrix. The polymer layer is closely attached to and covers the entire surface of the stent matrix. Since the flexible polymer layer closely covers the entire surface of the stent matrix not only the outer periphery of the stent matrix, the stent has no problem of causing allergic to metal, stimulus of tissues due to metal, and rust development. Since the inner periphery of the stent is a flat and smooth surface covered by the polymer layer without convexes and concaves, the formation of thrombus can be inhibited well. There is no problem of drift between the polymer layer and the stent matrix, thereby maintaining the positional relationship between the stent matrix and the polymer layer before and after the expansion of the stent.

Compact suture punch with malleable needle
A suture punch system is capable of directly passing braided suture through tissue in a simple, one-step process. The system includes three principle components: a malleable needle with braided suture attached, a handheld instrument for grasping tissue and controlling needle placement, and a trocar to supply the force required for needle placement. Needle deformation begins at the tip of the instrument, which preferably includes a curved segment. As the distal tip of the needle pierces the tissue, it continues its radial path through the tissue. When the proximal end of the needle exits from the instrument, the needle is entirely radial in shape and traverses an essentially radial path through the tissue. Non-radial linear or non-linear segments may alternatively be used. In one embodiment, the tissue to be sutured is constrained by pressure applied through closure between an upper, moveable jaw the distal portion of the instrument which acts as a fixed jaw. The upper, movable jaw contains a shaped passageway which allows the curved needle to pass therethrough during use. Once the needle has passed entirely through the tissue it is ready for retrieval using the jaws of the punch or another instrument. Different needle designs and separate instruments are also disclosed.
