Abstract
Medical devices and methods for making and using the same. An example method for manufacturing a medical device may include providing a metallic tubular member, cutting a plurality of slots in the tubular member, and chemically treating at least a portion of the tubular member to remove material from the tubular member and define a treated portion. The tubular member may include an outer diameter and an inner diameter. The slots may have a slot width. The treated portion may have one or more of a decreased outer diameter, an increased inner diameter, or an increased slot width in at least some of the slots.
Claims31
A method for manufacturing a medical device, the method comprising:
- providing a metallic tubular member, wherein the tubular member includes an outer diameter and an inner diameter;
- cutting a plurality of slots in the tubular member, wherein the slots have a slot width;
- chemically treating at least a portion of the tubular member to remove material from the tubular member and define a treated portion;
- and
- wherein the treated portion has one or more of a decreased outer diameter, an increased inner diameter, or an increased slot width in at least some of the slots.
A method for manufacturing a medical device, the method comprising:
- providing a nickel-titanium alloy tubular member, the tubular member having an outer diameter and an inner diameter;
- laser cutting a plurality of slots in the tubular member, wherein the slots have a slot width;
- and
- chemically etching at least a portion of the tubular member to remove material from the tubular member and define a treated portion, the treated portion having a decreased outer diameter, an increased inner diameter, and an increased slot width in at least some of the slots.
A medical device, comprising:
- an elongate shaft including a metallic tubular member, the tubular member having a length, an inner diameter, an outer diameter, and a plurality of slots formed therein;
- and
- wherein the inner diameter varies along the length of the tubular member.
A method for manufacturing a medical device, the method comprising:
- providing a tubular member, wherein the tubular member includes an outer diameter and an inner diameter;
- cutting a plurality of slots in the tubular member, wherein the slots have a slot width;
- chemically treating at least a portion of the tubular member to remove material from the tubular member and define a treated portion;
- and
- wherein the treated portion has one or more of a decreased outer diameter, an increased inner diameter, or an increased slot width in at least some of the slots.
A medical device, comprising:
- an elongate shaft including a tubular member, the tubular member having a length, an inner diameter, an outer diameter, and a plurality of slots formed therein;
- wherein the inner diameter varies along the length of the tubular member;
- and
- wherein the outer diameter varies along the length of the tubular member.
A method for manufacturing a medical device, the method comprising:
- providing a tubular member, wherein the tubular member includes an outer diameter and an inner diameter;
- forming a plurality of pockets in the tubular member, wherein the pockets have a pocket width;
