Patent number: 11864946Abstract: A medical assembly and method of use includes a catheter, a medical instrument and a navigation system. A localization element is attached to a handle of the catheter. A localization element is attached to a handle of the medical instrument. The localization elements are detectable by the navigation system. The medical instrument includes a needle, when the needle is positioned entirely within a working channel of the catheter, a tip of the needle is in an unextended position and the location elements are in a zeroed out position. When the needle tip extends out of the working channel to an extended position, the location elements are in an extension position. In the extension position the distance between the location elements is less than in the zeroed out position. The difference between the zeroed out position and the extension position is displayed on a display as a needle stroke value.Type: GrantFiled: October 18, 2021Date of Patent: January 9, 2024Assignee: Veran Medical Technologies, Inc.Inventors: Mark Hunter, Troy L Holsing

Patent number: 11832894Abstract: A medical instrument assembly including a handle assembly having a first handle portion and a second handle portion proximate the second end, wherein the second handle portion is slidably engaged with the first handle portion. A first localization element is attached to the first handle portion and a second localization element is attached to the second handle portion. A medical instrument is mechanically coupled to the second handle portion and a translation of the second handle portion with respect to the first handle portion causes a coincident and coextensive translation of the medical instrument. The amount of translation of the medical instrument is adapted to be determined by calculating the distance between the first localization element and the second localization element. The first and second localization elements may be electromagnetic sensors which positions may be determined by a navigation system.Type: GrantFiled: November 5, 2020Date of Patent: December 5, 2023Assignee: Veran Medical Technologies, Inc.Inventors: Christopher Lee, Mark Hunter, Troy L.

Publication number: 20230200877Abstract: A system and method are presented for treating targeted tissue using cryoablation. An introducer canula and a cryoprobe are inserted the targeted tissue. The cryoprobe is cooled and an ice ball is formed. The cryoprobe is removed while the ice ball is still frozen, and an ultrasound catheter is inserted. Ultrasound generated within the ice ball is used to determine the distance from the ultrasound catheter to a perimeter of the ice ball. This is repeated at different angles to model a slice of the ice ball. The ultrasound catheter is moved radially, and the process is repeated to create a model of at least a portion of the ice ball. The ice ball model can be displayed on a registered set of images representing the targeted tissue to ensure that the tissue lies within the treatment zone of the ice ball.Type: ApplicationFiled: February 21, 2023Publication date: June 29, 2023Applicant: Veran Medical Technologies, Inc.Inventors: Mark Hunter, Troy L.

Publication number: 20230115733Abstract: A system and method are presented for applying convolutional neural networks (CNNs) to aid in rapid on-site evaluation cytopathology. Image data are acquired from a biopsy slide. Areas of interest are determined using a first CNN. The image data is segmented into image tiles, and tiles showing the areas of interest are analyzed using a second CNN to assign a histologic category to the slide. The second CNN also utilizes site specific data relating to the biopsy location. Layered image data from multiple focal planes can be acquired of the slide and used as input to the second CNN. Categorized tiles are sorted and presented to a remote computing system for cytopathology determinations, aided by the results of applying the second CNN. Semantic segmentation can also be developed, both as input to the second CNN and as data presented to the remote computer system.Type: ApplicationFiled: October 7, 2022Publication date: April 13, 2023Applicant: Veran Medical Technologies, Inc.Inventors: Jayson Oldfather, Mark Hunter, Troy L.
