Abstract
A medical device includes a surgical needle, an elongated suture, and an intervening segment. The elongated suture has a first end proximate to the needle and a second end located away from the needle. The elongated suture also includes a plurality of fibers defining a mesh wall between the first and second ends. A plurality of pores extend through the mesh wall, at least some which are in the macroporous size range of greater than 200 microns for facilitating tissue integration when introduced into a body. The intervening segment is disposed between and connected to either or both ends of the elongated suture and the needle. The intervening segment includes one or more fibers of the plurality of fibers and has a cross-sectional dimension smaller than a cross-sectional dimension of the mesh wall such that the intervening segment facilitates indirect attachment of the elongated macroporous mesh suture to the needle.
Core Innovation
The invention relates to a medical device that includes a mesh suture having a first end and a second end. The mesh suture includes a porous flat strip with a plurality of fibers extending between the first end and the second end, and at least one fiber is configured to attach a surgical needle to the first end of the mesh suture.
The porous flat strip has a plurality of pores extending through the porous flat strip, with pores in a size range of 200 microns to 4 millimeters. The pores are adapted to facilitate tissue integration through the porous flat strip when the mesh suture is configured to be introduced into a body.
The document further describes configurations in which an intervening segment is arranged between the standard-sized surgical needle and the macroporous mesh suture, including a segment formed from one or more mesh fibers. In certain implementations, the intervening segment includes fibers bundled and/or tapered to a smaller cross-sectional dimension than the macroporous mesh wall so that the segment can be inserted into a needle blind bore or channel, with optional crimping and/or bonding/fixing.
The document also describes mesh structure variants, including tubular or flat mesh forms and alternative needle-to-segment connection schemes. These variants include anti-roping elements to prevent pore collapse under axial load, and optional anchors and material options, including biocompatible/biodegradable materials and bioactive agents.
Claims Coverage
The provided content includes one independent claim covering a porous flat mesh suture with needle attachment and macropores in a specified size range. Dependent claims further refine the device by adding dimensional constraints, specifying fiber construction types, and defining intervening segment configurations and material selections.
Porous flat mesh suture with needle attachment at the first end
A medical device comprising a mesh suture having a first end and a second end away from the first end, the mesh suture including a porous flat strip including a plurality of fibers extending between the first end and the second end, and at least one fiber of the plurality of fibers being configured to attach a surgical needle to the first end.
Macropores through the porous flat strip sized 200 microns to 4 millimeters
The medical device wherein a plurality of pores extends through the porous flat strip, the plurality of pores including pores in a size range of 200 microns to 4 millimeters, and the pores being adapted to facilitate tissue integration through the porous flat strip when the mesh suture is configured to be introduced into a body.
Claim coverage centers on a porous flat mesh suture with fibers configured for surgical needle attachment at the first end and pores through the porous flat strip in the 200 microns to 4 millimeters range adapted for tissue integration. The dependent claim refinements further constrain dimensions, fiber formation methods, intervening segment cross-sectional relationships, and selected material groups.
Stated Advantages
Facilitates tissue integration through the porous flat strip when introduced into a body.
Reduces inflammation and suture pull-through.
Provides anti-roping elements to prevent pore collapse under axial load.
Documented Applications
Used for surgical introduction into a body as a mesh suture configured to be introduced into a body.
Used as a medical device for attaching a standard-sized surgical needle to a macroporous mesh suture via an intervening segment.
