International Classification:

A61B 1700
US Classification:

606185, 606170
Abstract:

Devices and methods for percutaneous translumenal minimally invasive coronary surgery, particularly bypass surgery involving the following basic steps: determining a proper location for treatment, navigating a suitable device to the treatment site, creating an extravascular opening and pathway, guiding and/or monitoring the progress of creating the opening and pathway, and maintaining the extravascular opening and pathway. One or more extravascular openings and/or pathways may be created to define a fluid path or bypass around the vascular restriction. For example, an intravascular catheter for creating an extravascular opening in a vessel wall includes an elongate shaft adapted for intravascular navigation, an anchoring mechanism disposed on the distal end of the shaft, and a tissue penetrating member having a proximal end slidably disposed in the shaft and a distal end including a tissue penetrating mechanism.

Michael J. Urick - Quebec, CA
Assignee:

SciMed Life Systems, Inc. - Maple Grove MN
International Classification:

A61B 505
US Classification:

600547, 600585, 600549
Abstract:

Devices and methods for detecting vulnerable plaque within a blood vessel are disclosed. A system in accordance with the present invention includes a first wire having a distal end coupled to a voltage source and a proximal end coupled to an instrument capable of measuring voltage. A distal end of a second wire is also coupled to the voltage source and a proximal end of the second wire is coupled to the instrument. The amplitude of the electromotive force produced by the voltage source preferably varies with the temperature of a tissue proximate the voltage source.

US Patent:

6999807, Feb 14, 2006
Filed:

Jan 23, 2003
Appl. No.:

10/349674
Inventors:

Scott R. Smith - Chaska MN, US
Jaydeep Y. Kokate - Maple Grove MN, US
Leonard B. Richardson - Minneapolis MN, US
Eric M. Dobrava - Champlin MN, US
Assignee:

Scimed Life Systems, Inc. - Maple Grove MN
International Classification:

A61B 5/00
US Classification:

600310, 600317, 600342
Abstract:

The present invention relates to devices and methods for measuring the pH of blood in the vicinity of a vulnerable plaque. A balloon including an opto-electric device may be positioned proximate a vulnerable plaque. The balloon can be inflated to partially occlude blood flow enabling interaction between lipid laden blood and pH-sensitive material either within the balloon or on the wall(s) of the balloon. The selected pH-sensitive material is one whose optical properties change as a function of the pH of blood in the vasculature. An opto-electric device may be used for measuring the optical property and/or the change in the optical characteristics of the pH-sensitive compound.
