Patent number: 6358279Abstract: A mini capsulorhexis valve device is composed of a curved, flexible discoid flap-valve member shaped to align with an ocular lens capsular bag inner surface, and a curved, flexible retainer member shaped to align with an ocular lens capsular bag outer surface, the curved, flexible retainer member being attached at a fastening point to the curved, flexible discoid flap-valve member. Attachment of the curved, flexible discoid flap-valve member to the curved, flexible retainer member may be via bonding with a silastic adhesive. In a method of accessing an ocular lens, the mini capsulorhexis valve device establishes a portal controlling access to an ocular lens. The method may include inserting a cannula through the mini capsulorhexis valve device to permit removal of a crystalline lens matrix and replacement thereof with a capsular filling material.Type: GrantFiled: February 22, 2000Date of Patent: March 19, 2002Assignee: University of MiamiInventors: Hassan Tahi, Jean-Marie Parel, Pascal Chapon

Publication number: 20020002402Abstract: An integrated rigid fixation orbital expander has a coupling tunnel, an injection port, and a substantially spherically shaped expansion chamber. The coupling tunnel is configured with opposing side walls, a top wall and a bottom wall. The top wall of the coupling tunnel may have a depression denoting a mid-point of the coupling tunnel and serves as an entry point to introduce a needle for injection. The depression lines up with a hole on the vertical arm of a plate. The plate may glide within the coupling tunnel to align the depression with a desired hole in the plate. The injection port has a floor and a dome and a plurality of channels. The floor of the injection port may have a backstop plate to block a needle from further penetration. The dome of the injection port is connected to the bottom wall of the coupling tunnel.Type: ApplicationFiled: March 23, 2001Publication date: January 3, 2002Applicant: University of MiamiInventor: David T.

Publication number: 20010000487Abstract: A process and apparatus for rapid, continuous flow histological processing of tissues is disclosed. The steps of fixation, dehydration, clearing and impregnation are performed in less than one hour; this allows a pathologist to evaluate samples shortly after receipt, perhaps while the patient is still in the operating room. Rapid and continuous processing is accomplished by decreasing the thickness of tissue sections, use of non-aqueous solutions composed of admixtures of solutions, solution exchange at elevated temperature and with agitation, and impregnation under vacuum pressure. The patient in surgery is thus provided with point-of-care surgical pathology.Type: ApplicationFiled: December 15, 2000Publication date: April 26, 2001Applicant: The University of MiamiInventors: Ervin Essenfeld, Harold Essenfeld, Azorides Morales

Patent number: 6210399Abstract: A noncontact laser microsurgical apparatus and method for marking a cornea of a patient's or donor's eye in transplanting surgery or keratoplasty, and in incising or excising the corneal tissue in keratotomy, and for tissue welding and for thermokeratoplasty. The noncontact laser microsurgical apparatus comprises a laser source and a projection optical system for converting laser beams emitted from the laser source into coaxially distributed beam spots on the cornea. The apparatus further includes a multiple-facet prismatic axicon lens system movably mounted for varying the distribution of the beam spots on the cornea. In a further embodiment of the method of the present invention, an adjustable mask pattern is inserted in the optical path of the laser source to selectively block certain portions of the laser beams to thereby impinge only selected areas of the cornea.Type: GrantFiled: June 7, 1995Date of Patent: April 3, 2001Assignee: University of Miami, School of Medicine, Department of OphthalmologyInventors: Jean-Marie Parel, Takashi Yokokura, Katsuhiko Kobayashi

Patent number: 6127688Abstract: This invention includes an iso-energetic intensity modulating filter and method for therapeutic charged-particle beams, preferably electron beams, in which attenuating members are arranged to completely attenuate portions of the beam while permitting other portions of the beam to pass through the space between attenuating members. The attenuating members block the charged particles without producing any significant bremsstrahlung contamination in the filtered beam. The attenuating members can be arranged in a large number of configurations to obtain the desired modulated beam intensity profile. This invention also includes an improved iso-energetic, intensity-modulated charged-particle beam produced by the filtering device and method of this invention. A charged-particle beam therapeutic device and treatment method which has the iso-energetic intensity modulating filter is also included in this invention.Type: GrantFiled: February 6, 1998Date of Patent: October 3, 2000Assignee: The University of MiamiInventor: Xiaodong Wu

Patent number: 6091977Abstract: A plurality of locally sensitive, far-field immune sensors are mounted in mutually spaced relation on the exterior of the body of a subject to detect electrical signals associated with voluntary skeletal muscle activity in the immediate physical vicinity of the sensors. The detected signals are used to determine which, if any, of a predetermined series of voluntary skeletal muscle maneuvers is performed by the subject. A signal bearing a predetermined relationship to the maneuver is then transmitted to a device to be controlled based on which maneuver the subject has performed. Also disclosed are a novel sensor and a method of making same.Type: GrantFiled: October 5, 1998Date of Patent: July 18, 2000Assignee: The University of MiamiInventors: Peter P Tarjan, Monica Kaufer-Braverman, Leonard L.

Patent number: 5931846Abstract: The present invention provides a surgical technique and instrument kit that allows for subtle modification of the corneal curvature by interlamellar injection of a synthetic gel at the corneal periphery while sparing the optical zone. The gel viscosity, volume and disposition within the surgical annular track as well as the diameter of the track, width, depth, and location are all parameters in the refractive change obtained. Following ultrasonic pachymetry performed centrally and at a selected wound entrance located about 2.5 to 3.5 mm from the apex, a one millimeter or so wide, about 75-85% corneal thickness depth radial incision is performed with a micrometric diamond knife adjusted to about 86% corneal thickness. Inserted through the partial-depth incision, a corkscrew-like dissector or helicoidal spatula forms a 360.degree. annular track centered about the apex. A transparent gel is manually injected through the incision, filling the annular channel.Type: GrantFiled: February 27, 1997Date of Patent: August 3, 1999Assignee: University of MiamiInventors: Gabriel Simon, William Gerald Lee, Jean-Marie A.

Patent number: 5885244Abstract: A synchronous, pulsatile angioplasty system utilizes a control apparatus which controls balloon inflation and deflation in a pulsatile fashion synchronized with the heartbeat of a patient. A heart monitor provides an input, a signal to the control apparatus which serves as a baseline for operation of the pulsatile inflation and deflation of the balloon. A triggering circuit reads the baseline signal and generates a control signal to selectively generate valves interconnecting the angioplasty catheter with sources of inflation media and low pressure. Time delay circuits may be utilized which delay either the duration of the control signal or the receipt thereof by the control valves.Type: GrantFiled: May 14, 1997Date of Patent: March 23, 1999Assignee: Cordis Corporation & University of MiamiInventors: James E. Leone, Eduardo deMarchena

Patent number: 5786362Abstract: Activation of the c-fos promoter and the serum response element (SRE) in androgen independent cancer cells has been demonstrated. In androgen dependent cells, direct activation of protein kinase C (PKC) or serum response factor (SRF) activated the c-fos promoter or SRE and caused androgen independent expression of an androgen target promoter. The highly specific PKC inhibitor chelerythrine selectively killed androgen independent cells. Expression of mutant SRF cDNA's inhibited activation of the SRE in prostate cancer cells. These reagents demonstrate the feasibility of both chemotherapy and gene therapy in interfering with intracellular pathways on which androgen independent cells are dependent; i.e. a strategy is outlined for treating hormone independent cancer in which the PKC-SRE pathway is disrupted by either chemotherapy or gene therapy.Type: GrantFiled: June 16, 1994Date of Patent: July 28, 1998Assignee: University of MiamiInventor: Arnon Krongrad
