摘要： The present invention relates to a guidewire having a shaped three dimensional guide section. In the preferred embodiment the guide section is helical, and exerts an outward radial force on a lumen the guidewire is constrained in. The outward radial force can be measured or calculated according to methods of the present invention. Also described is a system comprising a guidewire and catheter where the force the catheter exerts on a body lumen can also be calculated. Apparatus and methods of making the guidewire are also disclosed, as well as alternative embodiments of the guidewire.

摘要： A system is provided having a catheter, a torque member extending longitudinally through a lumen of the catheter, a removal mechanism secured to a distal end of the torque member, and a guidewire having a guide section that extends through a lumen of the removal mechanism. The guide section defines a curved profile that is diametrically larger than the dimension of the removal mechanism. The guide section of the guidewire is adapted to be positioned inside a passageway of the occluding material, and provides a curved path along which the removal mechanism can be advanced inside the passageway of the occluding material to separate and remove occluding material.

摘要： Apparatus and methods are provided for restoring and maintaining an open passage or lumen in a body conduit, such as a blood vessel, which has become stenosed or occluded. The apparatus includes a stent which is specially adapted for inhibiting restenosis within the stent after implantation in a body passage. In various embodiments, the apparatus also includes a catheter or other device for operating the stent to inhibit restenosis within the stented region of the body passage. The methods presented include implanting the stent within a body passage, typically a blood vessel such as a coronary artery, which has become stenosed or occluded, and operating the stent to inhibit ingrowth of stenotic material which would result in restenosis of the stented region. The stent may be operated manually to inhibit or remove ingrowth of stenotic material, for example by introducing a catheter which acts on the stent, or the stent may operate automatically to inhibit or remove ingrowth of stenotic material without manual intervention.

摘要： Microcannulae are constructed with multiple components in a composite design, allowing the microcannulae to have varying mechanical and delivery properties that will enable ophthalmic treatments by minimally invasive means. The microcannula includes at least one flexible, tubular communicating element with an outer diameter of 350 microns or less, a proximal connector for introduction of materials, energy or tools. It may also include a reinforcing member attached to the communicating element, which may be designed to create variable stiffness along the length of the microcannula. The microcannula may also include other features such as a signal beacon near the distal tip.

摘要： Pelvic or other types of implants are provided that can include tensioning feedback components or portions, such as color changing polymer materials, such as polyacetylene. The color changing polymer can be included with, coated on or otherwise provided with a portion of slings or implant devices to provide targeted feedback to the user or physician of the tension applied to a particular device. A first color can be used to indicate a first (initial) tension or compression stage, and a second color can be used to indicate tensioning of the device beyond a predefined threshold.
