Abstract
Medical devices and methods for making and using medical devices are disclosed. An example medical device includes a pressure sensing guidewire. The pressure sensing guidewire may include a tubular member having a proximal portion and a distal portion. The distal portion may have a plurality of slots formed therein. The distal portion may have a first wall thickness along a first region and a second wall thickness different from the first wall thickness along a second region. A pressure sensor may be disposed within the distal portion of the tubular member.
Claims20
A pressure sensing guidewire, comprising:
- a tubular member having a proximal portion and a distal portion;
- wherein the distal portion has a plurality of slots formed therein;
- wherein the distal portion has a first wall thickness along a first region and a second wall thickness different from the first wall thickness along a second region;
- and
- a pressure sensor disposed within the distal portion of the tubular member.
A pressure sensing guidewire, comprising:
- a tubular member having a proximal portion, a distal portion, and a lumen defined therein;
- wherein the distal portion has a first region having a first wall thickness and a second region with a second wall thickness that is larger than the first wall thickness;
- wherein the distal portion has a plurality of slots formed therein;
- wherein at least some of the slots disposed along the first region have an increased slot width relative to slots disposed along the second region;
- wherein the first region includes a landing area that is free of slots;
- and
- a pressure sensor disposed along the first region and positioned adjacent to the landing area.
A method for manufacturing a pressure sensing guidewire, the method comprising:
- providing a tubular member having a proximal portion, a distal portion, and a lumen defined therein;
- drilling the distal portion of the tubular member so as to define a thinned wall region having a reduced wall thickness;
- forming a plurality of slots in the distal portion;
- and
- disposing an optical pressure sensor along the thinned wall region of the distal portion.
