Patents by Inventor Allan R. Will

Allan R. Will has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 6656214
    Abstract: A tubular prosthesis is implanted at a target location within a body lumen by transluminally placing and embedding an expansible prosthesis body within a sealing layer. The sealing layer occludes at least a circumferential band within an interface region between the prosthesis body and the inner wall of the body lumen, thus providing for blockage of body lumen flow past the prosthesis. The sealing layer may be introduced prior to or simultaneously with the prosthesis body. A tubular prosthesis may be implanted in blood vessels, particularly to protect aneurysms.

  • Publication number: 20030195614
    Abstract: The present invention provides modular bifurcated intraluminal tubular prostheses, particularly stents and stent-grafts, for the treatment of disease conditions, particularly aneurysms. Modular sections of the prostheses, or “prosthetic modules,” may be selectively assembled to form a prosthesis having characteristics which are tailored to the specific requirements of the patient, including branch angle and branch lumen sizes which match the patients vascular geometry. A Y-connector prosthetic module structure provides support and separation for each of the adjacent branching lumens. Radiopaque markers on the prostheses promote alignment between prosthetic modules and with the body lumen system.

  • Patent number: 6527787
    Abstract: Methods and devices for harvesting veins from the body. The methods and devices allow vein harvesting using laparoscopic procedures. A working space is created over the vein using standard laparoscopic procedures and a side-hooked wire is inserted into the working space and twisted to insert the side-hook under the vein. The wire is then pulled or drawn along the vein to separate the vein from the surrounding tissue. In an alternative embodiment, vein separation is accomplished by threading a soft rubber tube under the vein, grasping the ends of the tube so as to surround the vein, and then pulling the tube along the vein. In other embodiments, the working space is created with everting balloons.

  • Publication number: 20020169495
    Abstract: A liner is advanced through a narrowed region in a vessel such as the internal carotid artery. The liner is advanced through the narrowed region in a collapsed position. A stent is then advanced through the liner and expanded to open the narrowed region. The liner may also have an anchor which expands an end of the liner before the stent is introduced.

  • Patent number: 6203568
    Abstract: The present invention provides an endoluminal prosthesis for deployment in a body lumen of a patient body, the prosthesis comprising a tubular fabric liner and a radially expandable frame supporting the liner. A plurality of imagable bodies are attached to the liner, the imagable bodies providing a sharp contrast so as to define a pattern which indicates the prosthesis position when the prosthesis is imaged within the patient body. Preferably, each imagable body comprises a plate having first and second opposed major surfaces and a passage therebetween to facilitate stitching the imagable body to the liner. Advantageously, the imagable bodies can be aligned with the openings of a perforate frame structure so that at least some of the imagable bodies are visible through associated openings, but need not actually be attached to the frame directly.

  • Patent number: 6097978
    Abstract: The present invention provides methods and apparatus for measuring and/or marking the internal features of a patient body when those features are viewed under fluoroscopy or another medical imaging modality. Although suitable for the physiological measurement of many body lumens, including the intestines, the urethra, and the like, the present invention will find its most immediate use in the measurement of vascular lesions, particularly vascular aneurysms adjacent the aortoiliac junction and other bifurcations. The positions and bend angles of such branching body lumens can be accurately mapped on a panel which remains outside the patient body. By imaging the patient through the panel, and by providing markings on the panel which give a bright contrast when imaged, the panel provides a guide that highlights the length, position, and geometry of the luminal lesion.
