Patent number: 11382661Abstract: Methods, apparatuses and systems are described for implanting a plurality of fiducial markers into a tissue. Systems include a needle, a stylet sized to slide within a lumen of the needle, and a multi-stop stylet spacer having stopping features configured to engage with the stylet to stop the distal end of the stylet at one or more predetermined distances from the distal end of the needle. Methods for implanting a plurality of fiducial markers into a tissue are described and include inserting a needle preloaded with fiducial markers into a tissue, adjusting a multi-stop stylet spacer from a safety position to a first deployment position, deploying a first fiducial marker into the tissue, adjusting the stylet spacer from the first deployment position to a second deployment position, and deploying a second fiducial marker into the tissue.Type: GrantFiled: November 1, 2019Date of Patent: July 12, 2022Assignee: Covidien LPInventors: Eugene Campbell, John O.

Patent number: 11229541Abstract: Methods, apparatuses and systems are described for stent delivery and positioning to cover an access site. The method may include delivering the stent through an access site in a wall of the body lumen. In some cases, the method may include repositioning the stent within the body lumen to at least partially cover the access site with the stent. The stent may be repositioned within the body lumen by retracting the stent towards the access site such that a proximal portion of the stent at least partially covers the access site. The stent may then expand within the body lumen. In some cases, the stent may expand within the body lumen by releasing a primary constrainment member from the stent by pulling the primary constrainment member in a proximal direction away from the stent.Type: GrantFiled: January 8, 2019Date of Patent: January 25, 2022Assignee: Covidien LPInventors: John O.

Publication number: 20210137714Abstract: Methods, apparatuses and systems are described for deploying a stent into a body lumen. A stent delivery system may include a sheath with a partially-tubular first portion made from a first material and a second portion made from a second material that is adhered to the first portion to form a tubular body. In some cases, the first material may be chemically incompatible with the second material such that the adhesion between the first portion and second portion is free from cross-linked bonds. The stent delivery system may further include a guidewire lumen with a distal tip that may be slidably disposed within the sheath and a tubular stent disposed between the guidewire lumen and an inside surface of the sheath. The sheath may be formed by coextruding the first material and the second material to form a striped tubular body of the sheath.Type: ApplicationFiled: January 20, 2021Publication date: May 13, 2021Inventors: MADELINE A.

Publication number: 20210076911Abstract: Various apparatuses to attach a first medical device to a second medical device are described that allow the physician to grasp only a single device while the other device remains securely attached to the one being grasped. The apparatuses, once they are attached to the first medical device, are designed to be easily and quickly attached and detached to a second medical device, normally only requiring the use of one hand. Furthermore, the apparatuses oftentimes include a base that can easily couple and decouple from the portion that is attached to the second medical device so that if the need arises to separately use the second medical device, it can be decoupled from the first medical device without completely removing the apparatus from the second medical device.Type: ApplicationFiled: November 30, 2020Publication date: March 18, 2021Applicant: Boston Scientific Scimed, Inc.Inventors: John B.
