  • Patent number: 6797004
    Abstract: An intraocular lens system including one or more intraocular lenses (IOL) and a peripheral holder. The peripheral holder is configured to receive and retain the distal end of a fixation member of the IOL and provide a dynamic interface between the natural capsular bag and fixation member. The holder is preferably annular and flexible and transmits movement of the capsular bag from the surrounding ciliary muscles to the IOL. In this manner, a circumferential surface contact with the capsular bag is provided and accommodation of the IOL is improved. If two IOLs are received in the holder, a spacer may be provided to insure consistent spacing between the IOLs. Alternatively, an IOL system may include two IOLs and a spacer, without the holder. The holder desirably includes a sharp exterior corner to inhibit cell growth and posterior capsular opacification.

  • Patent number: 6508837
    Abstract: This invention is a pre-formed intrastromal corneal insert. It is made of a physiologically compatible polymer and may be used to adjust corneal curvature and thereby correct vision abnormalities. The insert or segment may also be used to deliver therapeutic or diagnostic agents to the interior of the cornea or of the eye. The insert subtends only a portion of a ring, or “arc”, encircling the anterior cornea outside of the cornea's field of view. The invention also includes a procedure for inserting the device into the cornea.

  • Patent number: 6503278
    Abstract: This invention relates to a material that degrades after implantation into a patient's tissue, and resorbs into the patient's body, which material is manufactured of polymer, copolymer or polymer alloy. The material has a non-crystalline, i.e., amorphous structure and is molecularly oriented and reinforced by mechanical deformation. Further, the material can be formed into surgical devices, such as screws and pins, for implantation into a patient.

  • Patent number: 6502576
    Abstract: This invention is a method for treating a patient diagnosed with atrial arrhythmia by forming a circumferential conduction block along a circumferential path of tissue in a pulmonary vein wall that circumscribes the pulmonary vein lumen and transects the electrical conductivity of the pulmonary vein such that conduction is blocked along the longitudinal axis of the vein wall and into the left atrial wall. The method is performed to treat a patient with a focal arrythmogenic origin along the pulmonary vein wall by either ablating the focal origin or by isolating the focal origin from the atrial wall with the circumferential conduction block. The circumferential conduction block is also formed in a pulmonary vein in order to bridge the adjacent ends of two linear lesions, wherein each linear lesion is formed to extend between the pulmonary vein and another adjacent pulmonary vein in a less-invasive “maze”-type procedure.

  • Patent number: 6503276
    Abstract: Intraocular lenses include a lens body sized and adapted for placement in a mammalian eye and having a plurality of different optical powers, and a movement assembly joined to the lens body and adapted to cooperate with the mammalian eye to effect accommodating movement of the lens body in the eye. Such intraocular lenses provide enhanced accommodation relative to the accommodation attainable using a single optical power IOL adapted for accommodating movement.

  • Patent number: 6485515
    Abstract: The device comprises a prosthesis designed as a hollow body compressed against the action of restoring spring forces to a cross section reduced relative to an expanded use position, and held in this position by a strippable sheath. After the sheath is stripped, the prosthesis automatically expands to a cross section corresponding to the use position. The sheath, which can be a meshwork in the approximate form of crocheted material, extends over the entire length of the prosthesis and consists of at least one continuous thread and at least one drawstring. The prosthesis, held in the radially compressed position by the sheath, can be mounted displacebly on a feed wire or non-axially-displacebly on the insertion end of a probe or a catheter.

  • Patent number: 6464725
    Abstract: A lens system for implantation in a human eye which makes it possible to restore accommodation. The lens system comprises one anterior lens (2) and a posterior lens (4), out of these two lenses one has positive and the other has negative lens power. Accommodation is achieved by varying the distance between the two lenses. This lens system can be made so as to generate large changes in optical power for small changes in position. It also allows the amount of change in optical power for any given amount of change in distance between the lenses to be selected relatively independently of the optical power of the overall lens system.

  • Patent number: 6450171
    Abstract: The symptoms of congenital heart failure are addressed in this surgical procedure for mounting a patch in the ventricle of the heart to reduce ventricular volume. Placement of the patch is facilitated by palpating a beating heart to identify akinetic, although normal appearing, tissue. An apical patch having an oval configuration facilitates return of the heart to a normal apical shape which enhances muscle fiber efficiency and a normal writhing pumping action. An inferior patch having a triangular configuration can also be used. The patches include a semi-rigid ring, and a circumferential rim to address bleeding. Patch placement is further enhanced by creating a Fontan-type neck and use of pledged sutures. Intraoperative vascularization and valve replacement is easily accommodated. Increased injection fraction, reduced muscle stress, improved myocardial protection, and ease of accurate patch placement are all achieved with this procedure.

  • Patent number: 6447477
    Abstract: A guide (100) is provided for biopsy and microtherapy which includes an introducer cannula (120) defining a lumen (125) sized to receive a diagnostic or therapeutic item therethrough and a lateral opening (124) in communication with the lumen (125) adjacent the first end (121) of the cannula (120). The invention also includes a solid tip (130) having an anatomically distal end (131) secured to the first end (121) of the cannula (120) and a proximal end (132) configured to pierce tissue. A ramp (135) is disposed within the cannula (120) at an end (136) of the lateral opening (124) adjacent the first end (121) of the cannula (120). The ramp (135) is inclined toward the lateral opening (124), whereby the item will be deflected through the lateral opening (124) as it advances within the lumen (125) and exits the cannula (120). In some embodiments, the item is a biopsy needle, ablation means or a radiopharmaceutical seed.
