Multi-lumen balloons and catheters made therewith

Abstract: Multi-lumen balloons for use as or in conjunction with balloon dilation catheters, and methods for making such balloons, are disclosed.

High-strength, thin-walled single piece catheters

Abstract: An integral, single-piece, high-strength, thin-walled, inflatable catheter is disclosed. The catheter has one end partially or entirely closed, and is at least uniaxially oriented along its entire length. The method and apparatus for making the catheter is also disclosed. The catheters of this invention have a calculated radial tensile strength of about 10,000 psi or greater at every point along the catheter.

Dilatation balloon fabricated from low molecular weight polymers

Abstract: A low molecular weight, flexible, biaxially oriented, dilatation catheter balloon comprising oriented polyethylene terephthalate, and having a calculated radial tensile strength of greater than about 25,000 psi.

Mobility Models for UAV Group Reconnaissance Applications

Abstract: In MANET research the mobility of the nodes is often described using standard synthetic models. Given a particular application, e.g. networks of unmanned aerial vehicles (UAVs) performing a cooperative task, the use of a standard synthetic mobility model can result in incorrect conclusions, as the movement pattern can impact the networking performance of the system. In this paper we present the criteria that characterize desirable mobility properties for the movement of UAVs in a reconnaissance scenario, and provide two mobility models for the scenario. In the first mobility model the UAVs move independently and randomly, and in the second model pheromones guide their movement. The random model is very simple but it achieves mediocre results. The pheromone model has very good scanning properties, but it has problems with respect to network connectivity. The study shows that there in an inherent conflict between the two goals of maximum coverage by frequent rescanning and adequate communication connectivity.

Method of treating obstructed regions of bodily passages

Abstract: An adjustable-length balloon dilatation catheter apparatus and a method for using the same are disclosed wherein an adjustable sheath is externally manipulated to partially surround and contain the dilatation balloon segment of the catheter while the catheter and balloon segment are in situ during a treatment procedure. By sliding the sheath forward or backward to expose a predetermined length of the balloon segment prior to inflating the balloon, the catheter apparatus of this invention is useful in medical procedures requiring balloons of varying lengths.
