Publication number: 20230346361Abstract: Multiple vascular wall penetrations are formed and sealed in a single blood vessel, typically a vein, for performing cardiac and other catheter-based procedures. Access sheaths are placed in two or more tissue tracts each having a vascular wall penetration at a distal end and into a lumen of the blood vessel. A catheter is advanced though each of the access sheaths to perform a therapeutic or diagnostic procedure. A vascular closure device is introduced through each access sheath, typically sequentially, and an occlusion element at a distal end of the device is deployed against an inner wall of the blood vessel in a manner so that the adjacent access sheath does not interfere or overlap with the deployed occlusion element. The vascular penetration at the distal end in that tissue tract may then be sealed prior to using another vascular closure device to seal a caudally adjacent vascular wall penetration.Type: ApplicationFiled: July 10, 2023Publication date: November 2, 2023Applicant: Cardiva Medical, Inc.Inventors: Zia Yassinzadeh, John L.

Patent number: 8265870Abstract: A method for establishing a detection map of a dynamically configurable sensor network. This method determines an appropriate set of locations for a plurality of sensor units of a sensor network and establishes a detection map for the network of sensors while the network is being set up; the detection map includes the effects of the local terrain and individual sensor performance. Sensor performance is characterized during the placement of the sensor units, which enables dynamic adjustment or reconfiguration of the placement of individual elements of the sensor network during network set-up to accommodate variations in local terrain and individual sensor performance. The reconfiguration of the network during initial set-up to accommodate deviations from idealized individual sensor detection zones improves the effectiveness of the sensor network in detecting activities at a detection perimeter and can provide the desired sensor coverage of an area while minimizing unintentional gaps in coverage.Type: GrantFiled: January 20, 2010Date of Patent: September 11, 2012Assignee: Sandia CorporationInventors: Hung D.

Patent number: 6589502Abstract: Therapeutic sources for use in the practice of brachytherapy are fabricated from radioactive composites of a radioactive powder of palladium-103, yttrium-90, phosphorus-32 or gold-198 and a biocompatible polymeric matrix. The particles of radioactive powder are dispersed within the polymer essentially randomly throughout a particular volume. The polymeric matrix is desirably manufactured with preselected flexibility suitable to its intended use, e.g. in the form of a rod, hollow rod, suture, film, sheet, or microspheroidal particles. The radioactive composites produce therapeutic sources which generate a radiation field that is substantially uniform in all directions. The therapeutic source may assembled from the radioactive composite during a medical procedure to emit the desired amount of therapeutic radiation. Optionally, the polymer is selected to dissolve or degrade in the body at a predetermined rate, the rate chosen depending upon the half life of the radioisotope used in the therapeutic source.Type: GrantFiled: November 27, 1995Date of Patent: July 8, 2003Assignee: International Brachytherapy s.a.Inventors: Roy Coniglione, John L.

Patent number: 4702228Abstract: Particles or "seeds" are manufactured for implantation into tumors within a human body for emitting X-rays to destroy or reduce the tumors. The seeds contain palladium which is substantially enriched in palladium-102 and which is activated by exposure to neutron flux so as to contain a minor, but significant, fraction of X-ray-emitting palladium-103. The palladium is distributed on or throughout a base material so as to reduce self-shielding by the palladium. The seeds include an X-ray-opaque marker to facilitate external visualization of the seeds after their implantation, the marker preferably being formed of a material, such as lead or rhodium, which does not activate to contain undesirable isotopes under the radiation conditions in which palladium-102 is activated to palladium-103.Type: GrantFiled: January 24, 1985Date of Patent: October 27, 1987Assignee: Theragenics CorporationInventors: John L.
