Medical devices and methods for delivering fluid. The medical devices include one or more needles for delivering fluid. The methods may optionally include expanding an expandable member such as an inflatable member to expand an expandable scaffold outward toward a lumen wall. The devices may include one or both of one or more spine securing members or one or more needle alignment members.

A delivery guide wire (10,100) and a therapeutic device are disclosed. The therapeutic device includes the delivery guide wire (10, 100), a medical implant and a delivery catheter (20). The delivery guide wire (10, 100) includes a core shaft (110) and a driving member (120) disposed on the core shaft (110), and the driving member (120) defines thereon a depression. The medical implant is compressed by the delivery catheter (20) and disposed over the delivery guide wire (10,100) in such a manner that it is at least partially received in the depression. This results in an increased contact area between the medical implant and the delivery guide wire (10, 100), which facilitates movement of the medical implant in sync with the delivery guide wire (10, 100) and makes its delivery easier.

A disclosure is provided for methods to prepare high-strength and high-toughness partially stabilized zirconia (PSZ) materials by incorporating a starting ceramic powder in which the stabilizing oxide agent is pre-alloyed with the zirconia material powder. The ceramic powder is pre-stabilized so there is little or no remaining free stabilizing oxide, thereby resulting in an improved material that is more convenient to process using conventional ceramic processing techniques.

A vaso-occlusive device is constructed out of dissimilar metallic materials that are in contact or otherwise in close proximity with one another, thereby causing the device to undergo galvanic corrosion when exposed to an electrolytic medium, such as blood or other body fluid, wherein one of the dissimilar metallic materials is zirconium or zirconium alloy to create a corrosive product including zirconia having a relatively high hardness, a relatively high fracture toughness, and a relatively high stability when the device is implanted in a vasculature site, such as an aneurysm.

The present disclosure provides a method for producing a multifunctional implantable structure, the method having: preparing an implantable base; coating a polymer layer on the base, wherein the polymer layer is partially curable; curing the polymer layer such that the polymer layer has cured and non-cured portions; and dry-etching the polymer layer to remove the non-cured portion thereof, to allow the polymer layer to have a nano-turf structure having pores defined therein.

A method for controlling generation of biologically desirable voids in a composition placed in proximity to bone or other tissue in a patient by selecting at least one water-soluble inorganic material having a desired particle size and solubility, and mixing the water-soluble inorganic material with at least one poorly-water-soluble or biodegradable matrix material. The matrix material, after it is mixed with the water-soluble inorganic material, is placed into the patient in proximity to tissue so that the water-soluble inorganic material dissolves at a predetermined rate to generate biologically desirable voids in the matrix material into which bone or other tissue can then grow.

Some embodiments are directed to a cellulite treatment system that contains a laser generating device. A hydrogel patch may include a region, at a first side of the hydrogel patch, to be in contact with a person's skin. The region may contain an adsorbing medium (e.g., carbon black or any other substance that would have a similar effect) that, when receiving a laser beam from the laser generating device, results in Extracorporeal Shock Wave Therapy (“ESWT”) being applied to the person's skin to treat cellulite.

An expandable stent for implantation in a body lumen, such as an artery, is disclosed. The stent consists of a plurality of radially expandable cylindrical rings generally aligned on a common longitudinal stent axis and interconnected by one or more interconnecting links placed so that the stent is flexible in the longitudinal direction. The link pattern is optimized to enhance longitudinal flexibility and high longitudinal strength compression of the stent.

An implant including an implant body to be inserted into biological tissue, the implant body having a hollow portion that penetrates the implant body, and an antibacterial property-imparting means that imparts an antibacterial property to at least the hollow portion of the implant body.

The infusion pump for stem cells includes a liquor storage device and an infusion pipe. The inner wall of the liquor storage sac of the liquor storage device and inner walls of the infusion pipe are provided with an anionic protective film to prevent stem cells from adhering to the infusion pump by mutual repulsion between anions. The infusion method includes checking an infusion pump for integrity, losing a liquor stop clamp, injecting a mixed liquor of stem cells and medicine, covering a protective cap, opening the liquor stop clamp, closing the liquor stop clamp for use, connecting an external cone joint with a venous cannula, and then opening the liquor stop clamp. The method also includes steadily placing the liquor storage sac on a horizontal plane using an auxiliary placing device, and after infusion ends, closing the liquor stop clamp, and disconnecting the external cone joint.
