Publication number: 20240123182Abstract: Aspects of an expandable sheath can be used in conjunction with a catheter assembly to introduce a prosthetic device, such as a heart valve, into a patient. Such aspects can minimize trauma to the vessel by allowing for temporary expansion of a portion of the introducer sheath to accommodate the delivery apparatus, followed by a return to the original diameter once the prosthetic device passes through. Some aspects can include a sheath with a tubular inner liner wound in a spiral configuration such that a plurality of protrusions is disposed in an overlapping portion of the sheath. The disclosed sheath is configured to expand from a predetermined rest diameter dr to an expanded diameter de during application of a radial outward force by passage of a medical device through the sheath.Type: ApplicationFiled: December 6, 2023Publication date: April 18, 2024Inventors: Erik Bulman, David Maimon, Sonny Tran, Ilan Tamir, Jeong Soo Lee, Maxwell Harrison Fine, Nasser William Saleh, Sovanpheap Mak, Tien Thi Nguyen

Such aspects can minimize trauma to the vessel by allowing for temporary expansion of a portion of the introducer sheath to accommodate the delivery apparatus, followed by a return to the original diameter once the prosthetic device passes through. Some aspects can include a sheath with a tubular inner liner wound in a spiral configuration at least a portion of the outer surface of the sheet comprises a plurality of bonding sites that are at least partially embedded within the sheet and disposed such that the outer surface of the sheet in the overlapping portion is substantially free of the plurality of bonding sites.Type: ApplicationFiled: December 6, 2023Publication date: March 28, 2024Inventors: Erik Bulman, David Maimon, Sonny Tran, Ilan Tamir, Jeong Soo Lee, Maxwell Harrison Fine, Nasser William Saleh, Sovanpheap Mak, Tien Thi Nguyen

Such aspects can minimize trauma to the vessel by allowing for temporary expansion of a portion of the introducer sheath to accommodate the delivery apparatus, followed by a return to the original diameter once the prosthetic device passes through. Some aspects can include a sheath with a tubular inner liner wound in a helical scroll slidable configuration. The disclosed sheath is configured to expand from a predetermined rest diameter dr to an expanded diameter de during the application of a radial outward force by passage of a medical device through the sheath.Type: ApplicationFiled: December 6, 2023Publication date: March 28, 2024Inventors: David Maimon, Erik Bulman, Sonny Tran, Ilan Tamir, Jeong Soo Lee, Maxwell Harrison Fine, Nasser William Saleh, Sovanpheap Mak, Tien Thi Nguyen

Publication number: 20240100297Abstract: Various systems, devices, and methods are described herein pertaining to expandable sheaths. Sheath aspects are described that include a flexible sheath tip that is expandable and bendable. In some aspects, the sheath includes a radially expandable proximal end and a radially expandable distal end. In some aspects, the sheath tip includes a plurality of layers that expand to accept a medical device traveling axially and bi-directionally therethrough with minimal deformation of the sheath tip.Type: ApplicationFiled: December 6, 2023Publication date: March 28, 2024Inventors: Sonny Tran, Ilan Tamir, Jeong Soo Lee, Maxwell Harrison Fine, Nasser William Saleh, Sovanpheap Mak, Tien Thi Nguyen, Erik Bulman, David Maimon

Patent number: 11931259Abstract: Disclosed herein are expandable introducer sheaths and methods of making and using the same. The sheaths minimize trauma to a patient's vasculature by allowing for temporary expansion of a portion of the sheath to accommodate passage of a delivery system for an implant, then return to a non-expanded state after the passage of the device. The sheath includes a foldable inner member having a detached flap structure at its distal tip that facilitates expansion of the sheath lumen to increased diameters, and an elastomeric distal end that reduces push and retrieval forces therethrough. The sheath can include a hemostasis seal on its proximal end to prevent the leakage of blood out of the sheath and prevent ballooning of outer layer of the sheath.Type: GrantFiled: May 4, 2020Date of Patent: March 19, 2024Assignee: EDWARDS LIFESCIENCES CORPORATIONInventors: Thanh Huy Le, Tung T. Le, Sovanpheap Mak, Alpana Kiran Gowdar, Richard D. White, Sonny Tran

Publication number: 20230355389Abstract: An expandable sheath including an elongated inner member defining a central lumen extending therethrough. The inner member includes a first circumferential portion including a first and second longitudinal edges, and a second circumferential portion extending between the first and second longitudinal edges. The wall thickness of the first circumferential portion is greater than the wall thickness of the second circumferential portion. The elongated inner member is configured to transition from an unexpanded configuration to an expanded configuration in response to a radially outward force on an inner surface of the central lumen. In the unexpanded configuration, the elongated inner member is creased proximate the first and second longitudinal edges into a folded configuration such that the second circumferential portion is positioned at least partially radially inward of the first circumferential portion.Type: ApplicationFiled: July 18, 2023Publication date: November 9, 2023Inventors: Sovanpheap Mak, Ilan Tamir, Maxwell Harrison Fine, Nasser William Saleh, Sonny Tran

Such aspects can minimize trauma to the vessel by allowing for temporary expansion of a portion of the introducer sheath to accommodate the delivery apparatus, followed by a return to the original diameter once the prosthetic device passes through. Some aspects can include a sheath with a variable diameter inner liner wound in a spiral slidable configuration and an outer layer. The disclosed sheath is configured to expand from a predetermined rest diameter dr to an expanded diameter de during application of a radial outward force by passage of a medical device through the sheath.Type: ApplicationFiled: August 26, 2022Publication date: March 2, 2023Inventors: Sonny Tran, Jeong Soo Lee, Nasser William Saleh, Ilan Tamir, Daniel J. Scherb, Maxwell Harrison Fine, Alpana Kiran Gowdar, Tri D. Tran, Neal H. Avery, Sarah Ghanbari, Uy D. Trinh, Sovanpheap Mak, Erik Bulman, Raymond Mercado

Publication number: 20220226115Abstract: Embodiments of a balloon assembly are disclosed. The balloon assembly can include an inflatable balloon having an inflated state and a deflated state. The balloon in the deflated state can include a valve retaining portion, a distal tapered portion connected to a distal end of the valve retaining portion, a proximal tapered portion connected to a proximal end of the valve retaining portion, a distal leg connected to the distal end of the distal tapered portion, and a proximal leg connected to the proximal end of the proximal tapered portion. The distal tapered portion can include one or more axial folds. The proximal end of the distal tapered portion can include a first radial fold connected to a second radial fold, the first and second radial folds forming a pocket extending distally at the proximal end of the distal tapered portion.Type: ApplicationFiled: April 6, 2022Publication date: July 21, 2022Inventors: Tung T. Le, Thanh Huy Le, Sovanpheap Mak, Maria L. Saravia, Kim D. Nguyen, Sonny Tran, David John Loos, Neal H. Avery
