摘要:
The invention is directed to a catheter formed at least in part of a multilayered member having a first layer which is fusion bondable to another catheter component such as the skirt of an inflatable balloon and a second layer which is adjacent the first layer having a melting point greater than the first layer so that the multilayered member of the catheter is not deformed when the other catheter component is fusion bonded to the first layer of the multilayered member. The second layer is preferably lubricious in nature. In one embodiment of the invention, the multilayered member is a tubular element with the lubricious second layer defining an inner lumen extending within the tubular element. The outer layer of the tubular member may extend beyond the distal end of the inner layer and form a non-traumatic distal tip. Alternatively, a flexible non-traumatic distal tip may be fusion bonded to at least the outer layer of the multilayered tubular member.

An LED having vertical topology and a method of making the same is capable of improving a luminous efficiency and reliability, and is also capable of achieving mass productivity. The method includes forming a semiconductor layer on a substrate; forming a first electrode on the semiconductor layer; forming a supporting layer on the first electrode; generating an acoustic stress wave at the interface between the substrate and semiconductor layer, thereby separating the substrate from the semiconductor layer; and forming a second electrode on the semiconductor layer exposed by the separation of the substrate.

A catheter comprising an elongated shaft having a distal shaft section with a first portion having co-axially disposed lumens, and a second portion having laterally off-set, adjacent lumens. The adjacent-lumen portion of the distal shaft section is preferably disposed proximal to the co-axial lumen portion, and comprises a first tubular member secured to a second tubular member such that the longitudinal axis of the first tubular member is laterally off-set from the longitudinal axis of the second tubular member. The coaxial lumen portion extends distally from the distal end of the adjacent-lumen portion, and generally comprises an inner tubular member disposed within an outer tubular member. One embodiment of the invention is a balloon catheter having an inflatable dilatation balloon on a distal end thereof.

Provided is a music generating device. The device includes a user interface, a lyric processing module, a melody generating unit, a harmony accompaniment generating unit, and a music generating unit. The user interface receives lyrics and melody from a user, and the lyric processing module generates a voice file corresponding to the received lyrics. The melody generating unit generates a melody file corresponding to the received melody, and the harmony accompaniment generating unit analyzes the melody file to generate a harmony accompaniment file corresponding to the melody. The music generating unit synthesizes the voice file, the melody file, and the harmony accompaniment file to generate a music file.
摘要:
A catheter having a mandrel secured to the catheter or constrained within a dedicated lumen. In one embodiment, the catheter has an inner tubular member and an outer tubular member with a sidewall configured to define a mandrel lumen longitudinally along an inner surface of the outer tubular member or along an outer surface of the inner tubular member. The mandrel lumen may be configured to allow the mandrel to be exchanged to adjust the handling characteristics of the catheter. The mandrel may occupy an intermediate portion of the catheter shaft, or may extend from the proximal end to within proximal or distal shaft sections of the catheter. In coronary artery applications, the mandrel is configured to support the catheter as it bends through the aortic arch and enters the coronary artery.
