Patent number: 6796936Abstract: An implantable radiation therapy device includes a biocompatible radiotranslucent outer capsule containing a radiation shielding element and a radioactive isotope at least partially shielded by the shielding element. When the device is at or below body temperature, radiation is prevented or limited from being transmitted through the outer capsule by the shielding element. When non-ambient energy is applied to the device, the shielding element and radioactive isotope are reconfigured such that an increased level of radiation is transmitted through the outer capsule and emitted by the device.Type: GrantFiled: October 28, 2002Date of Patent: September 28, 2004Assignee: Syntheon, LLCInventors: Charles R.

Publication number: 20030108659Abstract: A process for creating surface microporosity on a titanium (or other metal) medical device includes creating a surface oxide layer on the device; placing the device, which is connected to a negative terminal of an electrical power supply, into a calcium chloride bath; connecting the positive terminal of the power supply to an anode immersed in or containing calcium chloride thereby forming an electrolytic cell; passing current through the cell; removing the device from the bath; and cooling and rinsing the device to remove any surface salt. If necessary, the device is etched to remove metal oxide which may have formed during the cooling process. The resulting device has a microporous surface structure. Alternatively, only a designated surface portion of a medical device is made microporous, either by applying a non-oxidizing mask, removing a portion of the oxide layer, or subtracting a portion of a microporous surface.Type: ApplicationFiled: January 14, 2003Publication date: June 12, 2003Applicant: Syntheon, LLCInventors: Thomas O.
