Filed:

Aug 29, 2002

Appl. No.:

10/231374

Inventors:

Peter M. Nicholas - Boston MA, US

Assignee:

Boston Scientific SciMed, Inc. - Maple Grove MN

International Classification:

A61F002/06

US Classification:

623 134, 623 115

Abstract:

A medical device and method of providing same, comprises a first stent body and a second stent body wherein the medical device is formed when the at least one first marker portion and the at least one second marker portion of the stent bodies are positioned in a predetermined alignment wherein the first stent body and the second stent body are aligned along substantially the same longitudinal axis and at least a portion of the first end region and at least a portion of the second end region of the respective stent bodies are overlappingly arranged to provide the medical device with a longitudinal length that is less than the sum of the first stent body length and the second stent body length.

Assignee:

Boston Scientific Corporation - Natick MA

International Classification:

A61F 1100

US Classification:

606108

Abstract:

An inflatable medical device and method for the placement of a stent in a body passageway by means of a two stage expansion of the stent and for the delivery of medications to precise location in the passageway. The device includes a catheter shaft (14) having a plurality of lumens (13, 22, 28) disposed therein. The catheter shaft has a distal end adapted to be disposed within a vascular passageway. An inflatable balloon is defined by a generally cylindrical wall and is adapted to receive inflation fluids. The balloon is disposed on the distal end of the shaft. An array of circumferentially arranged inflation conduits (40) is disposed in the wall. The conduits (40) are spaced from each other within the wall of the balloon whereby to form a annular array. An array of medication delivering conduits (25) can be disposed within the wall of the balloon. These conduits are adapted to deliver medications to predetermined locations within the body passageway being treated.

International Classification:

A61B 812

US Classification:

Abstract:

An ultrasound imaging device has a stationary, elongated flexible tubular body, a rotatable drive shaft extending through the body, and a nose member located distally of the tubular body. The nose member is mounted on the distal end of the drive shaft to rotate therewith, and an acoustic imaging instrument is incorporated in the nose member for producing acoustic images of adjacent tissue as the drive shaft turns. The nose member is covered with a bio-compatible, acoustically transparent, lubricous coating of hydrophilic material sufficient to shield and space the nose member from the adjacent tissue. The lubricous coating of hydrophilic material covers an area of the surface of the ultrasound imaging device through which the acoustic imaging instrument causes acoustic signals to pass. The coating has sufficient thickness to avoid puncturing of a wall of a blood vessel by the nose member while the nose member rotates within the blood vessel sufficiently close to the wall for puncturing otherwise to occur.
