Publication number: 20240115319Abstract: An all-optical-fiber device configured to supply, to a target, laser radiation having characteristics sufficient for ablating a biological tissue in a manner that is consistent and competitive with the tissue removal geometry and volume provided by conventional electrocautery resection devices. The desired effect is achieved by configuring a facet of the optical fiber or an internal surface of the fiber's termination cap as a surface providing total-internal-reflection of light substantially at every point of such surface while having normals drawn to immediately adjoining surface portions be not parallel with respect to one another.Type: ApplicationFiled: October 2, 2023Publication date: April 11, 2024Applicant: CYCLONE BIOSCIENCES, LLCInventor: Stephen E. Griffin

Publication number: 20240085653Abstract: A holder of an optical fiber (a fiber-optic element) structured to house and secure the surgical optical fiber within the holder to prevent a possibility of the fiber to move at least axially and/or rotate about the axis while, at the same time, avoiding microbending of the surgical optical fiber (which such holder is configured to house) to prevent fiber burning during use of the surgical fiber with high-power laser sources. The holder is optionally and preferably configured as a controller of spatial orientation of the fiber output portion (which output portion remains invisible to the user during the application) that ensures that the output optical power is delivered from the termination of the optical fiber in the intended direction.Type: ApplicationFiled: August 1, 2023Publication date: March 14, 2024Applicant: Cyclone Biosciences, LLCInventor: Stephen E.

Patent number: 11911101Abstract: Optical fibers used to deliver laser energy inside the body are often twisted and bent when passed through tortuous routes in accessing the target tissue or pathology, e.g. during the ureteroscopic laser lithotripsy. When an irregular laser output that is produced at the start of the lasing process is channeled through a fiber that is bent at or near the bend limit, fail safe polymer claddings are damaged and can no longer contain even regular laser output in tight deflection. A common resulting fiber failure, known as ‘fiber burn through’, results in injuries to patients and is a major cause of damage to ureteroscopes. Discussed are the systems and methodologies providing a solution to such premature fiber failure.Type: GrantFiled: March 10, 2022Date of Patent: February 27, 2024Assignee: CYCLONE BIOSCIENCES, LLCInventors: Stephen E.

Patent number: 11272983Abstract: Optical fibers for delivering laser energy inside the body are often tasked with traversing tortuous routes in accessing the target tissue or pathology, e.g. ureteroscopic laser lithotripsy. A common failure in such applications, known in the field as ‘fiber burn through’, has been known to injure patients and is a major cause of damage to ureteroscopes. Where irregular output that is produced at the start of a lasing interval passes through a fiber that is at or near the optical minimum bend limit, fail safe polymer claddings are damaged and can no longer contain even regular laser output in tight deflection.

Patent number: 11097395Abstract: A tool for chamfering cleaved tips of optical fibers. The tool including conical bores of relatively smooth and hard material terminate at a cylindrical bore that is slightly larger than the fiber core maximum diameter and a fiber centering bore that is slightly larger than the fiber coating maximum diameter. The tool provided such that when a cleaved fiber tip is inserted into the centering bore the sharp edge falls upon the chamfer that, when rotated relative to the fiber, gently grinds the edge to the chamfer angle. Chamfering cannot occur on the core face due to the absence of tool surface at this dimension.Type: GrantFiled: February 7, 2017Date of Patent: August 24, 2021Assignee: CYCLONE BIOSCIENCES, LLCInventors: Stephen E.
