  • Patent number: 10307610
    Abstract: A prostate treatment system having a light delivery device positionable in a transurethral device for treatment of benign prostatic hyperplasia (BPH). The light delivery device includes light generator, such as light emitting diodes (LED), laser diodes (LDs) or a diffusion quartz fiber tip connected to a light generator or a light emitting polymer which produces light at a selected wavelength or waveband or alternative sources of suitable light energy. The treatment device may further include a temperature monitoring system for monitoring the temperature at the treatment site. A light-activated drug is administered to the treatment site prior to light activation. The light-activated drug therapy induces cell death of the target tissue. The device provides a minimally invasive transurethral method for treatment of BPH or prostate cancer.

  • Publication number: 20170246472
    Abstract: Systems, devices, and methods are described for providing, among other things, improvement in treatment of abnormal tissues including cancer, utilizing light activated drug therapy. Improvements include the use of optical penetration and drug penetration enhancers, in combination with photosensitizing drugs, and the use of localization aids and implements, which enable treatment of larger tissue volumes using minimal tissue access. The cytotoxic photoactivation process is also improved by using internal guidance to direct the light source to and at the lesion site using a naturally occurring orifice or intravascular access route.

  • Publication number: 20160213945
    Abstract: A photoreactive agent and a drug therapy device including a support member configured to pass through a urethra having proximal and distal ends and a longitudinal internal lumen. A light generator carried by the support member, potted within the lumen, and positioned within the urethra to deliver light to the prostate. The light generator generates a light band with a peak at a preselected wavelength. A power source external to the support member powers the light generator. The positioning element locates the support member within the urethra. A transparent/translucent, integral window is positioned proximate to the prostate and allows light to pass through. The window extends 360 degrees radially from the support member. The light generator has at least LEDs or LOs having a dimension of approximately 0.3 mm×0.3 mm×0.1 mm (length×width×thickness).

  • Patent number: 9149651
    Abstract: An energy treatment system to treat a patient includes an energy delivery device having a plurality of energy emitters used in combination with an energy activatable drug. A mask can be used to define a treatment area. Energy from the energy emitters passes through an optical window of the mask to activate a cosmetically and/or therapeutically effective amount of the activatable drug at the target site to bring about a desired change of tissue, for example, to reduce visibility of one or more blood vessels, while energy from the energy emitters directed outside of the target site is blocked by the mask.

  • Patent number: 8235975
    Abstract: A light transmission system to provide photodynamic treatment to a patient includes a single use integrated control module and catheter assembly having a plurality of light emitting diodes (LEDs) to transmit light toward target cells within a patient. The integrated light catheter and control module are used in combination with a light activated drug. Selected operating parameters may be programmed into the control module, or it may be wirelessly programmable in situ prior to use to allow user flexibility to tailor treatment for a particular patient or condition. Among the features that prevent reuse are that the control module lacks access to recharge the power source, and it may include a deactivation module that destroys circuitry or software when triggered. To prevent patient interference when in use, the control module may also be configured to selectively deactivate.

  • Publication number: 20100305436
    Abstract: A method and system is used to locate tissue for removal during a resection. The system includes a container that holds a photoactivatable agent capable of binding with unwanted tissue at a treatment site, a light source, and a viewing device. The light source is adapted to continuously output light that causes fluorescence of the photoactivatable agent in unwanted tissue. The system provides fluorescence-enhanced viewing of the treatment site through the viewing device. The viewing device has a filter that filters out light from the light source that is reflected from the treatment site while allowing a fluorescence emission from the photoactivatable agent to pass therethrough to each eye of the user. The light from the light source and the fluorescence emission are in different regions of the energy spectrum.
