An endograft (102) includes a stent structure. An optical shape sensing (OSS) system (104) is associated with the endograft and is configured to measure shape, position and/or orientation of the stent structure. The OSS system (104) is connected to the stent structure and removable in a plurality of ways. Methods for deployment and removal of the OSS system are also provided.

An endovascular self-curving stent-graft (20) includes a self-curving longitudinal portion (22), which is curved so as to define an innermost curve (26) and an outermost curve (28), when the stent-graft (20) is unconstrained in a radially-expanded state. The stent-graft (20) includes a plurality of circumferential strut members (30); a compression-generation spring (40), which (a) is in an elongated configuration when the stent-graft (20) is in a radially-compressed state, and (b) overlaps respective first portions (44) of at least two of the circumferential strut members (30); and an anti-buckling spring (50), which overlaps respective second portions (54) of at least two of the circumferential strut members (30). The anti-buckling spring (50) and the compression-generation spring (40) are together configured to curve the self-curving longitudinal portion (22) when the stent-graft (20) is unconstrained in the radially-expanded state, such that a lesser length of the self-curving longitudinal portion (22), measured along the innermost curve (26), is less than 80% of a greater length of the self-curving longitudinal portion (22), measured along the outermost curve (28).

A system for medical device deployment includes an optical shape sensing (OSS) system (104) associated with a deployable medical device (102) or a deployment instrument (107). The OSS system is configured to measure shape, position or orientation of the deployable medical device and/or deployment instrument. A registration module (128) is configured to register OSS data with imaging data to permit placement of the deployable medical device. An image processing module (142) is configured to create a visual representation (102′) of the deployable medical device and to jointly display the deployable medical device with the imaging data.

Devices, systems, and methods for reducing stress on a blood vessel are disclosed herein. A damping device configured in accordance with embodiments of the present technology can include an anchoring member coupled to a flexible, compliant damping member including a generally tubular sidewall having an outer surface, an inner surface defining a lumen configured to direct blood flow, a first end portion and a second end portion, and a damping region between the first and second end portions. The inner and outer surfaces of the damping member can be spaced apart by a distance that is greater at the damping region than at either of the first or second end portions. When blood flows through the damping member during systole, the damping member absorbs a portion of the pulsatile energy of the blood, thereby reducing a magnitude of the pulse pressure transmitted to a portion of the blood vessel distal to the damping device.

Provided are a silicone stent (100), an implantation system, and a manufacturing method. The silicone stent (100) includes a stent body (110). The stent body (110) includes a mesh frame (112) and a silicone body (111) molded on the mesh frame (112). A circumferentially sealed space (116) is defined within the silicone body (111). A distal end and a proximal end of the silicone body (111) respectively have a distal-end opening (115) and a proximal-end opening (114) that communicate with the space (116). The mesh frame (112) circumferentially covers the silicone body (111), and runs in an axial direction of the silicone body (111). The mesh frame (112) extends from the proximal end of the silicone body (111) to the distal end of the silicone body (111).
