Surgical removal. During surgical removal, the skin is numbed with an injection of a local anesthetic. The tattoo is removed with a scalpel, and the edges of skin are stitched back together. After the procedure, antibacterial ointment helps promote healing.

Hybrid imaging method to monitor medical device delivery and patient support for use in the method

This invention discloses a method and apparatus to deliver medical devices to targeted locations within human tissues using imaging data. The method enables the target location to be obtained from one imaging system, followed by the use of a second imaging system to verify the final position of the device. In particular, the invention discloses a method based on the initial identification of tissue targets using MR imaging, followed by the use of ultrasound imaging to verify and monitor accurate needle positioning. The invention can be used for acquiring biopsy samples to determine the grade and stage of cancer in various tissues including the brain, breast, abdomen, spine, liver, and kidney. The method is also useful for delivery of markers to a specific site to facilitate surgical removal of diseased tissue, or for the targeted delivery of applicators that destroy diseased tissues in-situ.

Devices and methods for tissue access

Methods and apparatus are provided for selective surgical removal of tissue, e.g., for enlargement of diseased spinal structures, such as impinged lateral recesses and pathologically narrowed neural foramen. In one variation, tissue may be ablated, resected, removed, or otherwise remodeled by standard small endoscopic tools delivered into the epidural space through an epidural needle. Once the sharp tip of the needle is in the epidural space, it is converted to a blunt tipped instrument for further safe advancement. A specially designed epidural catheter that is used to cover the previously sharp needle tip may also contain a fiberoptic cable. Further embodiments of the current invention include a double barreled epidural needle or other means for placement of a working channel for the placement of tools within the epidural space, beside the epidural instrument. The current invention includes specific tools that enable safe tissue modification in the epidural space, including a barrier that separates the area where tissue modification will take place from adjacent vulnerable neural and vascular structures. In one variation, a tissue abrasion device is provided including a thin belt or ribbon with an abrasive cutting surface. The device may be placed through the neural foramina of the spine and around the anterior border of a facet joint. Once properly positioned, a medical practitioner may enlarge the lateral recess and neural foramina via frictional abrasion, i.e., by sliding the abrasive surface of the ribbon across impinging tissues. A nerve stimulator optionally may be provided to reduce a risk of inadvertent neural abrasion. Additionally, safe epidural placement of the working barrier and epidural tissue modification tools may be further improved with the use of electrical nerve stimulation capabilities within the invention that, when combined with neural stimulation monitors, provide neural localization capabilities to the surgeon. The device optionally may be placed within a protective sheath that exposes the abrasive surface of the ribbon only in the area where tissue removal is desired. Furthermore, an endoscope may be incorporated into the device in order to monitor safe tissue removal. Finally, tissue remodeling within the epidural space may be ensured through the placement of compression dressings against remodeled tissue surfaces, or through the placement of tissue retention straps, belts or cables that are wrapped around and pull under tension aspects of the impinging soft tissue and bone in the posterior spinal canal.

Surgical guides and methods for positioning artificial teeth and dental implants

InactiveUS20080085489A1Eliminate radiographic scatterMedical simulationDental implantsDigital dataNatural tooth
A method is set forth for making a computer model of patient's jaws on the basis of digital information. Digital data about the jaws, teeth, soft tissues and artificial teeth is joined in computer space to create aesthetic and functional plans for the removal of teeth, shaping of supporting bone and placement of dental implants. Artificial teeth and pre-manufactured prosthetic devices are made and attached to the dental implants at the time of surgery. The aesthetic and functional position of artificial teeth is determined prior to surgical removal of natural teeth and the ideal position of implants and the proper form of the remaining bone are determined prior to surgery. Surgical guides used to shape bone, record occlusal orientation and position dental implants are manufactured using computer milling or layered manufacturing.

High temperature thermal therapy of breast cancer

A method is described for preventing breast cancer recurrence after surgical removal of a breast cancer mass. Specifically, the method is thermal treatment of breast tissue surrounding a cavity after lumpectomy for breast cancer. Delivery of a heated fluid is through a balloon catheter to the cavity generated after lumpectomy with the goal of ablating the surrounding tissue, including transformed cells that were not removed through surgery. A balloon and controller were designed for this application.

Intraocular lens optic

InactiveUS20100131059A1Accurate radiusIntraocular lensIntraocular lensCiliary epithelium
An intraocular lens optic (e.g. FIG. 1) having a maximum thickness of 500 microns (3) and a diameter of 6 millimeters, with concentric rings on the anterior surface of the lens. The lens, coupled with suitable haptic designs, is to be implanted within the lens capsule (19) of the eye after surgical removal of the natural crystalline lens. The anterior surface of the lens (1) has concentric rings (6) with steps of approximately 10 microns (5) that can be concave, convex or piano, with the edge of the step parallel in each case to the light rays traversing the lens at that point. The posterior surface of the lens (3) is aspherical and smooth. The concentric rings focus 95% or better of light at a specific target point on the retina, thus making a monofocal lens, with focal flexibility provided through haptic design providing movement of the lens forward in the posterior chamber in response to contraction and expansion of the ciliary body and concomitant repositioning of the zonules. The inventive lens is a unitarily formed, seamless body comprised preferably of hydrophilic acrylates or acrylates and silicone blends. Other possible materials include hydrophobic acrylates, polymethylmethacrylate (such as for example PMMA) or acrylic blends. The inventive lens, being less than 500 microns thick, provides greater transfer of light through the lens, thus more closely replicating the function of a natural, emmotropic lens, while the thinness, making the lens lightweight, allows the ciliary body to move the lens with less effort, thus facilitating comfort in the presbyopic eye.

Instrument for the surgical removal of a defective heart valve

An instrument for the surgical removal of a defective heart valve. The instrument has elements that can be collapsed, in which the instrument cutting elements are collapsed when the instrument is introduced into the surgical field and are covered by means of contact protective sheaths. The instrument cutting elements are formed as cutting ring halves that can fold in around a hinge axis, these cutting ring halves being elastically deformable during the folding-in process, whereby their deformation is achieved by fish joints that also serve to aid in mutually moving the contact protective sheaths onto each of two body members.
