    Abstract: A process to identify tumour characteristics involves obtaining three different marker sets each predictive of a characteristic of interest, obtaining a sample gene expression signals from tumour cells, adding a reporter to affect a change in the sample permitting assessment of a gene expression signal of interest in the tumour, combining the gene expression signals with the reporter, correlating the extracted gene expression signals to the three different marker sets, assigning a designation to the extracted gene expression signals according to the following rankings: if the correlation of all three predictive gene expression signal sets predict it to have characteristics of concern, it is designated a bad tumour; if the correlation of all three predictive gene expression signal sets predict it to lack characteristics of concern it is designated a good tumour; and, if the correlation of all three predictive gene expression signal sets do not provide the same predicted clinical outcome, the tumour is designated as “intermediate”; and, outputting said designation.

    Abstract: A catheter having an multilayered shaft section with a first layer formed of a polyimide first material and a second layer formed of a second material. In a presently preferred embodiment, the polyimide material is a thermoset polyimide. However, in alternative embodiments, a thermoplastic polyimide is used. The thermoset polyimide has a very high glass transition temperature (Tg) of approximately 400° C. (as measured by differential scanning calorimetry), and excellent dimensional stability at the processing temperature of polyamides commonly used in catheter components. As a result, during formation and assembly of the catheter, production of a thin polyimide layer with controlled dimensions is facilitated. The polyimide has a high modulus and provides a thin walled yet highly pushable shaft section, while the second layer provides kink resistance. In one embodiment, the second material is selected from the group consisting of a polyamide material and a polyurethane material.

    Abstract: A balloon catheter and a method of making a balloon catheter, having a balloon with a first layer and a second layer, the first layer having at least one impregnated section impregnated with a polymeric material compatible with a polymeric material forming the catheter shaft. At least a portion of the impregnated section is fusion bonded to the shaft. In a presently preferred embodiment, the impregnated section is adjacent to a section of the first layer which is not impregnated with the compatible polymeric material. The impregnated section provides improved bonding of the balloon to the catheter shaft while minimizing the effect of the bond on catheter performance characteristics such as profile and flexibility.
