Absorbable composite medical devices such as surgical meshes and braided sutures, which display two or more absorption/biodegradation and breaking strength retention profiles and exhibit unique properties in different clinical settings, are made using combinations of at least two types of yarns having distinctly different physicochemical and biological properties and incorporate in the subject construct special designs to provide a range of unique properties as clinically useful implants.

A hernia repair device, comprising: an inflatable balloon having an inflation tube, the inflation tube having a proximal end attached to said balloon and a distal end adapted to be extracted from the body, separately from the balloon, via an opening which is smaller than a laparoscopic opening; and a mesh removably attached to said balloon, wherein the inflation tube passes through the mesh.

The present invention is an implantable adhesive mesh prosthesis for reinforcing and/or repairing a defect in tissue that is easy to roll into a small diameter cylinder or other low-profile shape for passing through a trocar, incision, or other surgical instrument. More specifically, the adhesive may be applied to the mesh material in a pattern that leaves a significant portion of the surface area of the mesh material free of adhesive. In one embodiment, the adhesive is applied only near the outer perimeter of the mesh product. In another embodiment, the adhesive is applied in spots over all or a portion the surface of the mesh product. In yet another embodiment, the adhesive is applied in parallel lines on the surface of the mesh product and the mesh may be rolled up around an axis parallel to the lines of adhesive.

The invention relates to a method for forming a prosthetic base knit (1) made of two parallel sheets of porous knits, namely a first sheet (2) of porous knit and a second sheet of porous knit, said two parallel sheets being joined together in a discrete manner by a plurality of connecting porous knits (4) spaced apart from each other. The invention further relates to a method for manufacturing H-shaped prostheses for hernia repair from said base knit thus obtained and to the prostheses obtained therefrom.

A tendon repair implant for treatment of a partial thickness tear in the supraspinatus tendon of the shoulder is provided. The implant may incorporate features of rapid deployment and fixation by an arthroscopic means approach that compliment current procedures; tensile properties that result in desired sharing of anatomical load between the implant and native tendon during rehabilitation; selected porosity and longitudinal pathways for tissue in-growth; sufficient cyclic straining of the implant in the longitudinal direction to promote remodeling of new tissue to tendon-like tissue; and, may include a bioresorbable construction to provide transfer of additional load to new tendon-like tissue and native tendon over time.

The present invention relates to a weaving method for a nasal sinus stent, comprising: providing a filament; providing a weaving tool having a longitudinal central axis, wherein the weaving tool comprises a first shaping part and a second shaping part which are axially spaced from each other, wherein the first shaping part is provided with n first anchor points, and the second shaping part is provided with n second anchor points; forming an initial configuration stent by around a circumferential direction of the weaving tool, allowing a single filament starting from 1st first anchor point on the first shaping part, coming across m1 vertex intervals to extend towards the second anchor point, and then coming across m2 vertex intervals to extend towards the first anchor point, so as to complete a first “V” shaped weaving path, and then repeating the “V” shaped weaving path until the single filament returns to the 1st first anchor point, wherein the initial configuration stent has a circumference and n vertices with vertex interval obtained by dividing the circumference by n; m1 and m2 are integral multiples of 0.5, the sum of m1+m2 is an integer, and the sum of m1+m2 is not an integral multiple of a divisor of n. The sinus stent obtained by the above weaving method has good shape adaptability and is particularly suitable for being used as a self-expanding stent in the nasal cavity.

The invention relates to a knit having barbs protruding outwards from both faces obtained by knitting yarns of biocompatible material in guide-bars B2, B3 and B4 of a knitting machine, wherein the knitting patterns followed by guide-bars B2 and B3 involve at least two needles and produce an arrangement of yarns defining two faces of the knit, the knitting pattern followed by guide-bar B4 making stitches generating loops protruding outwards from each of the faces of the knit, guide-bar B4 being threaded with a hot-melt monofilament yarn, heat-setting the knit, forming barbs by cutting the loops via melting.

A warp knitted fabric formed by a warp knitting machine includes a first knitted portion formed using a first knitting sequence in a machine direction and a formed using a second knitted portion formed using a second knitting sequence in the machine direction, the second knitted portion comprising at least two strips extending in the machine direction, the at least two strips being detached from one another along their lengthwise edges. The second knitted portion has the same width as the first knitted portion, and the first knitted portion and the second knitted portion alternate sequentially in the machine direction and are formed of a single set of continuous textile strands.

An example implant delivery system is disclosed. The example implant delivery system includes a delivery shaft including a proximal portion, a distal portion and a lumen extending therebetween. The delivery system also includes a frame detachably coupled to the distal portion of the delivery shaft and a tack member coupled to the frame.

In a method of creating a modified tissue graft, at least one exterior surface of a graft is modified by compressing, cutting and/or removing one or more portions thereof, such as to create designed surface features which cause the tissue graft to have characteristics for a specific anatomical area. The modified tissue graft may comprise a medicated graft, such as by associating medicants with the surface features, or by associating a second graft or layer with a modified base tissue graft layer, where medicants are associated with the second graft or layer. The tissue graft may be modified by pressing a specially configured template or die, such as having blades thereon, into the tissue graft, such as to create a pattern of partial depth cuts.
