The resection device includes a magnet assembly implantable into a body cavity of the patient, the magnet assembly including a plurality of magnet elements flexibly connected in series. The magnet assembly is configured to be positioned around a portion of an outer surface of the solid organ to magnetically attract opposite magnet elements together to compress opposite sides of the solid organ along a resection line therebetween to separate the solid organ in a resectioned portion and a remaining portion. The magnet elements can be received in a housing and have various shapes. The resection device can include additional features such as a leading elongated member that can aid in the positioning of the resection device, and a trailing elongated member. ## Claims ### Claim 1 A resection device to resection a portion of a solid organ in a body cavity of a patient, the resection device comprising: a magnet assembly implantable into the body cavity of the patient and comprising: a plurality of magnet elements flexibly connected in series; wherein the magnet assembly is configured to be positioned against at least a portion of an outer surface of the solid organ to magnetically couple opposing ones of the plurality of magnet elements together to compress opposite sides of the solid organ therebetween along a resection line to subject the solid organ to ischemic pressure necrosis along at least a portion of the resection line to form a resectioned portion and a retained portion over time. ### Claim 2 (depends on 1) The resection device of claim 1, wherein: each one of the plurality of magnet elements comprises a magnet-engaging side to magnetically couple opposing magnet-engaging sides of the plurality of magnet elements facing each other; and the magnet assembly comprises a first zone and a second zone, the magnet-engaging sides of the magnet elements of the first zone of the magnet assembly having a first zone magnetic pole, and the magnet-engaging sides of the magnet elements of the second zone of the magnet assembly having a second zone magnetic pole that is different from the first zone magnetic pole. ### Claim 3 (depends on 2) The resection device of claim 2, wherein the magnet-engaging side of each of the plurality of magnet elements has a smaller surface area compared to a side of each of the plurality of magnet elements located opposite the magnet-engaging side. ### Claim 4 (depends on 2) The resection device of claim 2, wherein the plurality of magnet elements in the first zone forms a first enclosed shape and the plurality of magnet elements in the second zone forms a second enclosed shape, the first enclosed shape being substantially similar to the second enclosed shape and corresponding to an enclosed shape. ### Claim 5 (depends on 2) The resection device of claim 2, wherein the plurality of magnet elements in the first zone and the plurality of magnet elements in the second zone together form an enclosed shape. ### Claim 6 (depends on 5) The resection device of claim 5, wherein adjacent ones of the plurality of magnet elements forming the enclosed shape are flexibly connected in series to each other via a connector configured to retain the enclosed shape. ### Claim 7 (depends on 5) The resection device of claim 5, wherein the magnet elements of the first zone and the magnet elements of the second zone are each received in a housing defining the enclosed shape. ### Claim 8 (depends on 1) The resection device of claim 1, wherein the magnet elements comprise bevelled edges. ### Claim 9 (depends on 1) The resection device of claim 1, wherein adjacent ones of the plurality of magnet elements are flexibly connected in series via a flexible connector. ### Claim 10 (depends on 1) The resection device of claim 1, wherein the resection device is configurable between a pre-resection configuration and a resection configuration. ### Claim 11 (depends on 1) The resection device of claim 1, wherein the resection device comprises a curved region. ### Claim 12 (depends on 1) The resection device of claim 1, wherein an attractive force of the magnet elements is determined so as to facilitate placement and implantation of the resection device around the portion of the outer surface of the solid organ. ### Claim 13 (depends on 1) The partitioning device of claim 1, wherein the plurality of magnet elements flexibly connected in series are provided in sufficiently close proximity to enable formation of a substantially continuous resection line. ### Claim 14 (depends on 1) The resection device of claim 1, wherein the plurality of magnet elements is received in a housing. ### Claim 15 (depends on 14) The resection device of claim 14, wherein the housing comprises bevelled edges. ### Claim 16 (depends on 1) The resection device of claim 1, wherein each magnet element of the plurality of magnet elements is received in a corresponding housing. ### Claim 17 (depends on 16) The resection device of claim 16, wherein the corresponding housing comprises bevelled edges. ### Claim 18 A resection device to resection a portion of a solid organ of a patient, the resection device comprising: a leading elongated member and a trailing elongated member; and a magnet assembly extending between the leading elongated member and the trailing elongated member, the magnet assembly being implantable into a body cavity of the patient and comprising: a plurality of magnet elements flexibly connected in series; wherein the magnet assembly is configured to be positioned around a portion of an outer surface of the solid organ by guiding the leading elongated member of the resection device to magnetically couple opposing ones of plurality of magnet elements together to compress the solid organ therebetween along a resection line to subject the solid organ to ischemic pressure necrosis along at least a portion of the resection line to form a resectioned portion and a retained portion over time. ### Claim 19 (depends on 18) The resection device of claim 18, wherein at least one of the leading elongated member and the trailing elongated member is configured to anchor the resection device subcutaneously or outside the patient while opposite sides of the solid organ are compressed between the opposing ones of the plurality of magnet elements. ### Claim 20 (depends on 18) The resection device of claim 18, wherein the leading elongated member and the trailing elongated member comprise a continuous elongated member configured to be slidably engageable with the magnet assembly.
