摘要:
A catheter system comprises a catheter, an inner shaft, an expandable balloon, and an elongate advancement member. The expandable balloon has an unwrapped state and rewrapped state and the advancement member has a first state and a second state. When the advancement member is in the first state the expandable balloon is in the unwrapped state, and when the advancement member is in the second state the expandable balloon is in the rewrapped state. The unwrapped state has a first length and a first diameter, the rewrapped state has a second length and a second diameter, the second length is equal to or greater than the first length, and the second diameter is less than first diameter. The advancement member in the second state extends through the interior region defined by the expandable balloon.

The present invention is directed to distal tip designs for catheter, wherein distal tip material is positioned about an inner shaft. The distal tip material may also be used as a tie layer for thermally bonding two incompatible materials together, such as a waist portion of a balloon to the inner shaft.

A removable loading tool for use with a catheter assembly wherein the loading tool comprises a body which defines a substantially hollow chamber. The substantially hollow chamber has a first portion and a second portion. The first portion has a first diameter sized to contain at least a portion of the catheter assembly having a stent mounted thereon. The second portion has a second diameter less than that of the first diameter. The body constructed and arranged to protect the at least a portion of the catheter assembly and the stent from undesired contact or damage during loading of a guide wire into the catheter assembly.

13-benzenesulfonylhydrazone anthracyclines useful in producing improved yields in the synthesis 13-deoxyanthrcyclines, and an improved method of reducing 13-benzene-sulfonylhydrazone anthracyclines to 13-deoxyanthrcyclines wherein the reduction reaction is maintained at temperatures of about 55° C. to 64° C. without stirring or agitation. The reaction is completed with the addition of aqueous bicarbonate which forms the 13-deoxyanthracycline and precipitates. The precipitates are filtered and the precipitate and filtrate are extracted separately with organic solvents. The crude 13-deoxy anthracycline can be converted to 5-imino-13-deoxy anthracycline by reaction with methanolic ammonia. The reaction can also be performed with an acidic pyridinium salt instead of a strong acid so that neutralization of the reaction or extraction of the product is not necessary, thereby facilitating purification.
摘要:
This invention relates to novel lactams having drug and bio-affecting properties, their pharmaceutical compositions and methods of use. These novel compounds inhibit the processing of amyloid precursor protein and, more specifically, inhibit the production of Aβ-peptide, thereby acting to prevent the formation of neurological deposits of amyloid protein. More particularly, the present invention relates to the treatment of neurological disorders related to β-amyloid production such as Alzheimer's disease and Down's Syndrome.
