  • Publication number: 20170128741
    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: 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: RE46504
    Abstract: A light delivery system to provide light treatment to a patient includes a catheter assembly having a plurality of light sources that transmit light towards a target site within a patient. In one embodiment, the light delivery system has a plurality of light sources mounted to a flexible transparent base that extends at least partially through a distal tip of the catheter assembly. The light sources can be wire bonded or mounted in a flip chip arrangement onto the base. In one embodiment to produce the distal tip, an array of light energy sources can be held by an array of holders of a fixture device. A vacuum is applied to secure each light energy source in a corresponding holder. While the vacuum is applied, the energy sources are electrically connected by wire bonding. The vacuum can be reduced or stopped thereby permitting removal of the light energy sources from the fixture device.
