Patent number: 8298277Abstract: Embodiments of the present invention are directed to devices for allowing a user to deploy a stent in an anatomical lumen of a patient. For example, one embodiment is directed to a device including a longitudinally extending inner tubular member and a longitudinally extending outer tubular member that are longitudinally and axially displaceable relative to one another. The outer tubular member includes at least one longitudinally extending channel formed between the exterior and interior diameter of the outer tubular member. In addition, the device includes a handle configured to displace the outer tubular member and inner tubular member relative to each other in response to user intervention and a stop configured to coaxially engage the handle to form a safety mechanism. Displaceability of the outer tubular member and inner tubular member relative to each other is limited by the safety mechanism to a predetermined threshold.Type: GrantFiled: November 12, 2009Date of Patent: October 30, 2012Assignee: Merit Medical Systems, Inc.Inventors: Eric K.

Patent number: 8206436Abstract: The present invention, in an exemplary embodiment, provides a stent, which combines many of the excellent characteristics of both silicone and metal stents while eliminating the undesirable ones. In particular, a principal objective in accordance with the present invention is to provide a family of stents where the relative hardness/softness of regions of the stent can differ from other regions of the stent to provide additional patient comfort and resistance to compression forces. Exemplary embodiments provide a stent that is coated in a manner that limits the amount of coating surface area that is in direct contact with the target lumen. In particular, a covered stent is provided that is coated internally such that the outer scaffolding surface of the stent is raised from the outer surface of the coating. To this end, cilia function is only partially limited and mucociliary clearance is not significantly affected.Type: GrantFiled: November 11, 2009Date of Patent: June 26, 2012Assignee: Merit Medical Systems, Inc.Inventors: Eric K. Mangiardi, Jason M. Reynolds, Ulf R. Borg

Patent number: 8012106Abstract: A lumen measuring device generally includes a central member dimensioned to extend into a lumen and an elongate outer member having a flexible region configured to flex outward from the central member in response to retraction of the central member. In measuring a lumen, the flexible region is caused to contact the lumen. The lumen may be contacted by linear segments that hinge or by members that bow arcuately. A polygon, such as a triangle, may be defined by portions of the outer member and the central member. A handle assembly may be provided by which the disposition of the central member relative to the outer member may be adjusted. Indicators may be defined by the central member and outer member by which the disposition of the central member and by which the diameter of a lumen may be determined.Type: GrantFiled: October 17, 2005Date of Patent: September 6, 2011Assignee: Merit Medical Systems, Inc.Inventors: Eric K.

Patent number: 7959671Abstract: The present invention, in an exemplary embodiment, provides a stent, which combines many of the excellent characteristics of both silicone and metal stents while eliminating the undesirable ones. In particular, a principal objective in accordance with the present invention is to provide a family of stents where the relative hardness/softness of regions of the stent can differ from other regions of the stent to provide additional patient comfort and resistance to compression forces. Exemplary embodiments provide a stent that is covered so as to provide certain predefined characteristics. In particular, a covered stent is provided that is coated internally such that the outer scaffolding surface of the stent has enhanced friction points while the internal surface exemplifies certain characteristics.Type: GrantFiled: November 20, 2003Date of Patent: June 14, 2011Assignee: Merit Medical Systems, Inc.Inventors: Eric K.

Publication number: 20040193243Abstract: The present invention, in an exemplary embodiment, provides a stent deployment apparatus comprising excellent safety and stent placement and deployment features. An exemplary stent deployment apparatus in accordance with the present invention can facilitate the precise delivery of stents in a safe and repeatable fashion. In particular, a preferred deployment apparatus allows the physician to concentrate on correct placement without having to estimate extent of deployment by providing a physical safety mechanism that limits deployment to the critical deployment point. Moreover, to exceed this threshold, an audible and/or tactile indicator informs the physician that she can no longer retract the stent beyond this point. The stent deployment apparatus guidewire may also be extended rather than retracting the outer catheter to deliver the stent.Type: ApplicationFiled: March 31, 2003Publication date: September 30, 2004Inventors: Eric K.
