Abstract: Delivery system for fixation device, including guide catheter with proximal end portion having proximal end port, distal end portion having distal end port, and inner surface defining inner lumen extending in fluid communication between proximal end port and distal end port. Delivery catheter extending through the inner lumen to define annular space between outer surface of the delivery catheter and inner surface of the guide catheter. A pressure sensor proximate the proximal end portion in fluid communication with the annual space to monitor fluid pressure. The distal end portion of the guide catheter includes flow passages in fluid communication between an exterior of the distal end portion and the annular space.

Abstract: An intravascular device includes a shaft having a body defining a major lumen and a plurality of minor lumen. The minor lumens are spaced about the major lumen. The major lumen and the plurality of minor lumen extend from a proximal end of the body to a distal end of the body. One or more wires may extend through the major lumen and/or minor lumen.

Abstract: Methods and systems for controlling the moisture content of biodegradable and bioresorbable polymer resin during extrusion above a lower limit that allows for plasticization of the polymer resin melt and below an upper limit to reduce or prevent molecular weight loss are disclosed. Methods are further disclosed involving plasticization of a polymer resin for feeding into an extruder with carbon dioxide and freon.

Abstract: Bioresorbable polymer vascular scaffolds made of combinations of polylactide and polycaprolactone having a high molecular weight polymer, thin struts in a selected range and sufficient radial strength to support a vessel upon deployment. The scaffolds have degradation behavior of molecular weight, radial strength, and mass that are conducive to healing of a vessel including providing patency to a vessel, reduction of radial strength, breaking up, and resorbing to allow return of the vessel to a natural state.

Abstract: A medical device includes a polymer scaffold crimped to a balloon. The balloon is formed with between 6 and 15 pleats to provide a uniform expansion of the scaffold when the balloon is inflated. Also provided are methods for crimping a scaffold to a multi-pleated balloon and methods for making a multi-pleated balloon.
