Methods for forming an expandable tubular body having a plurality of braided filaments including a first filament including platinum or platinum alloy and a second filament including cobalt-chromium alloy. The methods include applying a first phosphorylcholine material directly on the platinum or platinum alloy of the first filament and applying a silane material on the second filament followed by a second phosphorylcholine material on the silane material on the second filament. The first and second phosphorylcholine materials each define a thickness of less than 100 nanometers.

Systems and methods for preparing a ligament graft for a ligament reconstruction procedure are provided. In general, the described techniques utilize a graft preparation system having a holder and a delivery suture assembly removably coupled thereto. The delivery suture assembly can include a spine coupled with an anchor suture configured to form a self-tightening knot used to position the assembly around a graft and a plurality of suture windings configured to be affixed to the graft when the assembly is deployed. The assembly is delivered to the graft using the holder and the sutures can be affixed to the graft without penetrating therethrough. The spine helps to evenly distribute the load among the windings compressing the graft which are thus are capable of withstanding increased loads. Thus, an improved, simplified, and time- and labor-saving approach to preparing ligament grafts is provided.

Methods for making surgical implants (or grafts) for the repair of bone defects, and more particularly, surgical implants that include demineralized bone fibers, are disclosed. Also disclosed are methods for increasing the wettability and ensuring uniform density of such implants. The surgical implants have a wettability time of less than 5 minutes and a residual moisture content of less than 6% by weight, and they remain cohesive and retain their shape upon complete rehydration.

The three-dimensional lattice structures disclosed herein have applications including use in medical implants, Some examples of the lattice structure are structural in that they can be used to provide structural support or mechanical spacing In some examples, the lattice can be configured as a scaffold to support bone or tissue growth Some examples can use a repeating modified rhombic dodecahedron or radial dodeca-rhombus unit cell. The lattice structures are also capable of providing a lattice structure with anisotropic properties to better suit the lattice for its intended purpose.

Medical devices in accordance with various embodiments of the present invention employ one or more coaxial screw gear sleeve mechanisms. In various embodiments, coaxial screw gear sleeve mechanisms include a post with a threaded exterior surface and a corresponding sleeve configured to surround the post, the corresponding sleeve having a threaded interior surface configured to interface with the threaded exterior surface of the post and a geared exterior surface. A drive mechanism can be configured to interface with the geared exterior surface of the sleeve, causing the device to expand.

The present invention relates to a prosthesis (100) comprising an openworked three-dimensional knit (101) comprising a front face and a rear face, each face being formed with one or more laps of yarns defining pores on said face, the front face being bound to the rear face by connecting yarns defining a spacer, characterized in that the connecting yarns are distributed so that they define an entanglement of yarns crossing each other at the spacer, without obstructing the pores of the front and rear faces.

An intraocular lens (IOL) punch includes a handpiece having an opening at a first end, a jaw comprising a first leg and a second leg joined at a first rod end of a rod, the rod extending into the opening and moveable relative to the handpiece to operate the jaw between an open position and a closed position, and a post attached to the first leg and extending toward the second leg, wherein in the open position there is a gap between the post and the second leg and in the closed position the post extends to the second leg closing the gap.

A prosthetic capsular device configured to be inserted in an eye after removal of a lens, in some embodiments, can comprise a housing structure comprising capable of containing an intraocular device. The housing structure can comprise an anterior portion comprising an anterior opening, a posterior portion comprising a posterior opening, and a continuous lateral portion between the anterior portion and the posterior portion.

Embodiments of the present invention provide medical devices and methods for treating a target site within the body. For example, one embodiment provides a stent graft for treating a target site proximate to a bifurcated lumen, wherein the stent graft includes a first tubular structure having proximal and distal ends and a side wall extending therebetween. The first tubular structure includes an opening defined within the side wall and is configured to define a first portion having first and second ends and a second portion having first and second ends. The opening corresponds to the first ends of the first and second portions and the second ends of the first and second portions respectively correspond to the proximal and distal ends of the first tubular structure, and at least a portion of the first and second portions are configured to be positioned within respective branches of a bifurcated lumen.

Methods for whip-stitching soft tissue with a needle and a looped suture avoid placing the tissue graft through the suture loop, which also eliminates the need for passing a tissue clamp through the suture loop. The methods described herein can also include combinations of the techniques described.
