Abstract
Embodiments of the present invention provide medical devices for treating a target site within the body and associated methods for fabricating and delivering medical devices. According to one embodiment, a medical device includes a tubular structure having proximal and distal ends and a side wall extending therebetween. At least a portion of the side wall can have a corrugated surface. The side wall further includes at least one layer of a metallic fabric configured to be compressed and heat set to define the corrugated surface. The tubular structure may comprise an expanded shape, and may be configured to be constrained to a smaller diameter than the expanded shape for delivery within a catheter to a target site and to assume the expanded shape upon release from the catheter.
Claims20
A method for manufacturing a medical device comprising:
- providing a tubular structure comprising at least one layer of metallic material, the tubular structure having a proximal end, a distal end, and a side wall extending therebetween, the tubular structure having an initial diameter in a non-corrugated configuration;
- forming the tubular structure such that the side wall defines at least one corrugated surface extending at least partially between the proximal and distal ends, the corrugated surface comprising a plurality of peaks and valleys defining an outer diameter and an inner diameter, respectively, the inner diameter of the valleys being larger than the initial diameter of the tubular structure in the non-corrugated configuration;
- and
- heat setting the formed tubular structure in an expanded preset configuration.
A method for manufacturing a medical device comprising:
- providing a tubular structure having a non-corrugated configuration comprising at least one layer of metallic material, the at least one layer of metallic material comprising a plurality of metallic strands, the tubular structure having a proximal end, a distal end, and a side wall extending therebetween, the tubular structure having an initial inner diameter in the non-corrugated configuration;
- compressing the tubular structure such that the side wall defines at least one corrugated surface extending at least partially between the proximal and distal ends, the tubular structure being compressed such that the plurality of metallic strands repeatedly buckle, the at least one corrugated surface having a plurality of peaks and valleys defining an outer diameter and an inner diameter, respectively, the tubular structure being compressed such that an inner diameter of the valleys is larger than the initial diameter of the tubular structure in the non-corrugated configuration;
- and
- heat setting the compressed tubular structure.
