Abstract
Improved methods, designs and/or systems for incorporating markings and/or other visual and/or tactilely identifiable indicia on woven, knitted, nonwoven, braided and/or felted textiles used for medical textile implants and prostheses, including medical graft prostheses that would not affect the overall mechanical performance of the textile.
Core Innovation
The invention relates to indicator marking on medical textiles that use a marking from an ultra-violet (UV) laser. The marking indicator is configured to preserve mechanical performance of the medical textile, including by maintaining burst strength substantially equal to an unmarked medical textile.
A key aspect is aligning the UV laser marking indicator parallel to a portion of a secondary yarn of the medical textile. The medical textile includes a primary yarn and a secondary yarn and can be formed as a textile structure with one or more material properties.
The marked medical textile is further defined by how the UV marking indicator is disposed to create marked and unmarked portions, and by requirements on mechanical performance of the marked portion relative to the unmarked portion. The document also describes preserving strength by defining the textile and marking characteristics, including alignment with textile directions and constraints on material and yarn properties.
Claims Coverage
The patent includes two independent claims. Each independent claim centers on using a UV laser marking indicator in a medical textile while preserving mechanical performance using specific structural alignment and performance thresholds.
UV laser marking aligned parallel to secondary yarn to preserve mechanical performance
A marked medical textile comprises a medical textile including a primary yarn and a secondary yarn, and a marking indicator comprising a marking from a UV laser, where the marking indicator is aligned parallel to a portion of the secondary yarn to preserve mechanical performance, and the preservation of mechanical performance comprises a burst strength substantially equal to an unmarked medical textile.
UV marking disposed to create marked and unmarked portions with burst strength not less than unmarked
A custom marked medical textile comprises a medical textile including a primary yarn and a secondary yarn with the primary yarn interlaced in a first direction with the secondary yarn in a second direction to create a textile structure including one or more material properties, and an ultra-violet (UV) marking indicator disposed onto a portion of the medical textile creating a marked portion and an unmarked portion, where the marked portion includes a burst strength equal to or greater than a burst strength of the unmarked portion.
Overall, the claims define UV laser/UV marking indicators for medical textiles and require mechanical performance preservation measured by burst strength, using parallel alignment of the marking to a secondary yarn portion and a marked-versus-unmarked burst strength relationship.
Stated Advantages
Preserves mechanical performance of the marked medical textile, including maintaining burst strength substantially equal to an unmarked medical textile.
Provides a marked portion having a burst strength that is equal to or greater than the burst strength of the unmarked portion.
Documented Applications
Indicator marking on medical textiles that includes an ultra-violet (UV) laser marking indicator configured to preserve mechanical performance.
Custom marked medical textile constructions where a UV marking indicator creates marked and unmarked portions while meeting burst strength requirements.
