Abstract:
Medical devices and methods for making and using the same. An example medical device may include a guidewire. The guidewire may include an elongate shaft. The shaft may include a porous metal alloy. The porous metal alloy may be arranged so that the porous metal alloy has a first pore distribution along a first portion of the shaft and a second pore distribution different from the first pore distribution along a second portion of the shaft.
Abstract:
A method of producing a tubular member which includes providing at least one micro-extruder configured to extrude at least one material and providing a surface configured to accept the material extruded from the micro-extruder.
Abstract:
A system and method for the electrostatic spray application of a coating material onto a medical device. The coating material is electrically charged and an atomizer is used to atomize the coating material, creating electrically charged droplets which coat the medical device. In alternate embodiments, a swirl atomizer, a pressure atomizer, an ultrasound atomizer, a rotary atomizer, and an effervescent atomizer are used to atomize the coating material.
Abstract:
The invention relates to a water soluble container which contains a composition useful for hard surface cleaning. The composition comprises a cationic surfactant having germicidal properties, a non-ionic surfactant, an alkali salt, an organic acid; and optionally, conventional additives, where the composition is in powder form. The water soluble containers can be made by thermoforming or injection molding.
Abstract:
Alkaline aqueous hard surface cleaning compositions which exhibit good cleaning efficacy against hardened dried or baked on greasy soil deposits. They are storage stable, and are not undesirably irritating to the skin or mucous tissues of the user. These compositions comprise in percent by weight (based on 100% total weight of a composition):0.01-0.85% wt. nonionic surfactant compound based on an amine oxide;0-1.5% wt. chelating agent;0.01-2.5% wt. caustic;3.0-9.0% wt. glycol ether solvent system comprising one glycol ether or glycol ether acetate solvent having a solubility in water of not more than 20% wt., and a second glycol ether or glycol ether acetate having a solubility of approximately 100% wt., wherein the ratio of the former to the latter is from 0.5:1 to 1.5:1;0-5.0% wt. of a water soluble amine containing organic compound;0-2.5% wt. soil anti-redeposition agent;0-2.5% wt. optional constituents.The compositions according to the invention contain no anionic or cationic type surfactant constituents, and include no more than 10% wt. of volatile organic constituents (VOCs). Methods for the use of such cleaning compositions, and processes for their production are also disclosed.
Abstract:
A medical balloon catheter including a catheter shaft and an inflatable balloon secured to a distal portion of the catheter shaft. One or more cutting blades are secured to the inflatable balloon by a first polymeric adhesive material forming a mounting pad encasing a base portion of the cutting blade therein, and a second polymeric adhesive material adhesively bonding the mounting pad to a surface of the balloon. The first polymeric adhesive material has a first ductility and the second polymeric adhesive material has a second ductility greater than the first ductility.

Abstract:
A stent formed from a bioabsorbable polymer matrix including at least one bioabsorbable polymer and at least one therapeutic agent dispersed therein, and methods of making the same.
Abstract:
A system is provided for spray coating medical devices, comprising a rotary atomizer with one or more rotary heads and a plurality of holders to hold a plurality of medical devices, such as stents, wherein the holders are positioned around a longitudinal axis of the rotary head. A method of using such a system is also provided. The invention enables the use of rotary atomizers to coat small medical devices with reduced waste of coating material and allows increased production throughput by the coating of multiple devices simultaneously. The rotary atomizer may be an electrostatic rotary atomizer. The holders and/or a holding structure on which the holders are mounted may move relative to the rotary atomizer.
