摘要:
A portion of a covered stent is encapsulated with ePTFE, so that the unencapsulated portion, which is covered by a single ePTFE covering, imparts an unimpaired flexibility to the stent. One surface of the stent, either the luminal or abluminal surface, is covered by a single continuous layer of ePTFE, while limited regions, preferably near the ends of the stent, of the other surface are also covered by ePTFE. The regions covered by ePTFE on both surfaces become encapsulated when the ePTFE of one layer becomes bonded to second layer. By leaving a middle region of the stent unencapsulated, the stent retains flexibility similar to a bare stent, thereby reducing the loading and deployment forces.

A covered stent including a stent covered on a first surface by a continuous covering and on a second surface by a discontinuous covering, the discontinuous covering bonded to the continuous covering, the discontinuous covering including first and second rings of material spaced apart such that a region of the second surface is uncovered.
摘要:
A flexible covered stent includes a stent covered on a first surface by a first layer of biocompatible material and on a second surface by a second layer of biocompatible material, the first and second layers of biocompatible material being bonded to one another through a wall in the stent. The first layer of biocompatible material is longer than the second layer of biocompatible material such that at least a portion of the second surface of the stent is left uncovered, imparting flexibility to the stent. A mid portion of the second surface of the stent can be left uncovered to impart flexibility to the stent similar to that enjoyed by a bare stent.
摘要:
A flexible covered stent having a stent covered on a first surface by a first layer of biocompatible material and on a second surface by both a second and third layer of biocompatible material, the first and second layers and the first and third layers of biocompatible material being bonded to one another through openings in a wall in the stent. The first layer of biocompatible material is longer than both the second and third layers of biocompatible material such that at least a portion of the second surface of the stent is not covered by either second or third layer, imparting flexibility to the stent.

摘要:
In a patient bed system, comprising a patient bed, a support column for supporting the bed and a trolley for transporting the bed, the bed having arranged on it first coupling elements (22) which are intended for selective connection to second or third coupling elements (24, 26) on the support column and on the trolley respectively, at least one of the coupling elements (24) located on the support-column side has provided on it at least one sensor (102) for sensing the position of a first coupling element (22) connected to the bed (18) in relation to the column-side coupling element (24), the sensor (102) taking effect when the bed is located on the trolley and the latter assumes in relation to the support column a specific position for transferring the bed onto the latter.

The present invention provides a synthesis for the preparation of epothilone derivatives of formula 9 wherein R1 is methyl, and R2 is an unsubstituted or substituted aryl; an unsubstituted or substituted heteroaryl; or an unsubstituted or substituted heterocyclic radical fused to a benzene nucleus; and salts thereof, and intermediates for the synthesis of a compound of formula 9.
摘要:
An operating table column has a column part a head part, and a plurality of actuating drives that each comprise a first element and a second element that can be linearly adjusted relative to this first element and that acts upon the head part. The first element of a first actuating drive is connected to the column part, while the head part is pivotably connected to the second element of the first actuating drive. The first element of a second actuating drive is pivotably connected to the column part, whereby, the head part is pivotably connected to the second element of the second actuating drive. The first element of a third actuating drive is connected at a distance from the head part to the second element of the first actuating drive and the second element of the third actuating drive is connected to the head part via respective universal joints.
