A medicine delivery mechanism or fibrin injection mechanism for use in combination with an anastomosing and stapling attachment for an electromechanical device driver comprises a dispensing chamber with an elongated cylindrical cross section (although other shapes can be used) which is formed in the staple housing of the attachment in lieu of a staple port or staple ports, and which has a mouth forming a channel lined at its innermost edge perimeter with inward facing prongs or teeth. The dispensing chamber contains a sac filled with fibrin. A delivery or plunger driver travels within the dispensing chamber to press a sac of fibrin against the inward facing prongs, tearing the sac and releasing the fibrin to push the fibrin through the channel to the treatment site.

An annuloplasty repair segment for heart valve annulus repair. In one embodiment a multi-stranded cable replaces solid core wire for both the tricuspid and mitral valves. Cable allows for greater deployment flexibility for minimally-invasive surgical (MIS) implant, while still maintaining the required strength and similar tensile properties of solid-core wire. Stranded cable provides a MIS annuloplasty ring with sufficient flexibility in the x-y plane to allow a surgeon to squeeze the ring into a small incision, such as being able to pass through an 18Fr or smaller catheter, while maintaining structural rigidity under forces exerted on the implanted ring by the cardiac cycle. The particular shape of the annuloplasty ring is fixed using a heat setting process.

The first layered member has a specific gravity that is less than those of the second layered member and the third layered member.

Shape memory polymers prepared by copolymerizing two monomers, which each separately produce polymers characterized by different glass transition temperatures in the presence of a multi-functional monomer whereby the copolymer formed is cross-linked during the polymerization to form a thermoset network. The transition temperature of the final polymers is adjusted by the ratio of the monomers selected, to from about 150° C. to about 270° C., while the degree of crosslinking controls the rubbery modulus plateau. The shape memory polymers can be processed as castable formulations in the form of bulk articles, coatings and films. The invention also relates to the articles of manufacture thereof and methods of the preparation and use thereof.

An annuloplasty repair segment for heart valve annulus repair. In one embodiment a multi-stranded cable replaces solid core wire for both the tricuspid and mitral valves. Cable allows for greater deployment flexibility for minimally-invasive surgical (MIS) implant, while still maintaining the required strength and similar tensile properties of solid-core wire. In addition, selective placement of point-welds or other such control points locally control other parameters such as the amount and direction of displacement as the ring undergoes external loading. Cable with well-placed control points result in a MIS annuloplasty ring with sufficient flexibility in the x-y plane to allow a surgeon to squeeze the ring into a small incision, such as for example 1 cm×1 cm, while maintaining structural rigidity under forces exerted on the implanted ring by the cardiac cycle and allowing for asymmetrical deflection to be designed into the product.
