Patent number: 11419523Abstract: Medical devices and methods for determining the size of blood vessels are disclosed. In one implementation, a blood vessel sizing device is configured for placement on an area of skin of a patient. The device includes a plurality of radiopaque concentric-circle elements. In one implementation, a blood vessel sizing method includes placing a marker having a plurality of concentric-circle elements on the skin of a patient, imaging a blood vessel of the patient and the device, and comparing the imaged blood vessel to the imaged circles to determine the blood vessel size, the concentric-circle elements allowing a determination of size without errors of parallax.Type: GrantFiled: May 15, 2019Date of Patent: August 23, 2022Assignee: SIZER LLCInventor: Richard B.

Patent number: 10959804Abstract: Medical devices and methods that provide for improved accuracy when positioning of a synthetic structure, such as a MEMS device or a stent, within a biological feature of a patient, such as a blood vessel, are disclosed. A blood vessel sizing device is configured for placement on the skin of a patient near a feature of interest (e.g. a blood vessel to be imaged). The device may include one or more radiopaque elements, including a target element, and one or more positioning markers having known sizes. A clinician may use the radiopaque elements to identify a portion of a blood vessel suitable for positioning of the synthetic structure.Type: GrantFiled: October 6, 2017Date of Patent: March 30, 2021Assignee: Sizer LLCInventor: Richard B.

Patent number: 7632304Abstract: In an embodiment, a stent is provided for use in blood vessels with blockage near or in a bifurcation. The stent includes a side aperture. The stent is inserted into one of the daughter branches of the bifurcation and positioned with the use of markers. The stent is then expanded so as to support the wall of the blood vessel while allowing the blood to continue to flow to both daughter branches.Type: GrantFiled: September 7, 2005Date of Patent: December 15, 2009Assignee: RBKPark LLCInventor: Richard B.
