Abstract
Embodiments of a Urological implant include an implant with an elongated body having a longitudinal axis. Optionally longitudinal ribs symmetrically oppose each other and are connected to elongated body. The longitudinal ribs are optionally elastically shiftable between a collapsed state and an expanded state relative to the spinal longitudinal axis, in order to retract or/and support periurethral tissue. Optionally the system includes an implant extraction handle. The extraction handle is optionally positioned proximally to the elongated body and connected to the longitudinal rib and subject to a pulling force to facilitate and/or force approximation of the longitudinal supports to the longitudinal axis. In some embodiments, an implant body includes longitudinally spaced arched members, interconnected via arch ends sequentially along a length of a first and second longitudinal rib. Optionally the arched members are elastically bendable to facilitate elastic contractibility of the implant body under a transverse compressive force.
Core Innovation
The invention relates to an implant for retracting or/and supporting a prostatic urethra wall. The implant has an elongated implant body defining a longitudinal channel with a longitudinal axis extending between a cranial end and a caudal end, and a median plane including the longitudinal axis with an anterior-posterior axis perpendicular to the longitudinal axis and a lateral axis perpendicular to the median plane.
A pair of longitudinal ribs is located on opposite sides of the median plane and posterior to the longitudinal axis. Cranial-most connecting members connect each of the pair of longitudinal ribs to a first apex located on the median plane anterior to the pair of longitudinal ribs, and in an unstressed configuration each cranial-most connecting member extends laterally and posteriorly from the first apex to each respective longitudinal rib.
Caudal-most connecting members are located caudal to the cranial connecting member and connect each longitudinal rib to a second apex located on the median plane caudal to the first apex and anterior to the pair of longitudinal ribs, wherein in an unstressed configuration each caudal-most connecting member extends laterally and posteriorly from the second apex to each longitudinal rib. In one configuration, a height in an anterior direction of the first apex from a connection between the cranial-most connecting member and each longitudinal rib is greater than a height in the anterior direction of the second apex from a connection between the caudal-most connecting member and each longitudinal rib.
In another configuration, a third connecting member connects the pair of longitudinal ribs to a third apex located on the median plane, anterior to the pair of longitudinal ribs between the second apex and the first apex, and the third connecting member is located between one caudal-most connecting member and the cranial-most connecting member.
Claims Coverage
The partial content includes three independent claims (clm-00001, clm-00017, clm-00018). Across these independent claims, the coverage centers on the geometric definition of an implant for retracting or/and supporting a prostatic urethra wall, including an elongated body with a longitudinal channel, a defined median plane and lateral axis, and a pair of longitudinal ribs connected to multiple median-plane apices by cranial-most, caudal-most, and optionally third connecting members.
Implant with rib-connected cranial and caudal apices on a median plane
An implant for retracting or/and supporting a prostatic urethra wall having an elongated implant body defining a longitudinal channel with a longitudinal axis between a cranial end and a caudal end, a median plane including the longitudinal axis with an anterior-posterior axis perpendicular to the longitudinal axis, a lateral axis perpendicular to the median plane and including a crossing point of the anterior-posterior axis and the longitudinal axis, and a pair of longitudinal ribs on opposite sides of the median plane and posterior to the longitudinal axis, where cranial-most connecting members connect each longitudinal rib to a first apex on the median plane anterior to the pair of longitudinal ribs and extend laterally and posteriorly in an unstressed configuration, and caudal-most connecting members connect each longitudinal rib to a second apex on the median plane caudal to the first apex and anterior to the pair of longitudinal ribs and extend laterally and posteriorly in an unstressed configuration, with the caudal anterior apex being cranial to each connection between the caudal-most connecting member and each longitudinal rib.
Implant with first apex anterior height greater than second apex anterior height
An implant for retracting or/and supporting a prostatic urethra wall having an elongated implant body defining a longitudinal channel with a longitudinal axis between a cranial end and a caudal end, a median plane including the longitudinal axis with an anterior-posterior axis perpendicular to the longitudinal axis, a lateral axis perpendicular to the median plane and including a crossing point of the anterior-posterior axis and the longitudinal axis, and a pair of longitudinal ribs on opposite sides of the median plane and posterior to the longitudinal axis, where a cranial-most connecting member connects each longitudinal rib to a first apex on the median plane anterior to the pair of longitudinal ribs and extends laterally and posteriorly in an unstressed configuration, and a caudal-most connecting member connects each longitudinal rib to a second apex on the median plane caudal to the first apex and anterior to the pair of longitudinal ribs and extends laterally and posteriorly in an unstressed configuration, wherein a height in an anterior direction of the first apex from a connection between the cranial-most connecting member and each longitudinal rib is greater than a height in the anterior direction of the second apex from a connection between the caudal-most connecting member and each longitudinal rib.
Implant with third connecting member and third apex between second and first apices
An implant for retracting or/and supporting a prostatic urethra wall having an elongated implant body defining a longitudinal channel with a longitudinal axis between a cranial end and a caudal end, a median plane including the longitudinal axis with an anterior-posterior axis perpendicular to the longitudinal axis, a lateral axis perpendicular to the median plane and including a crossing point of the anterior-posterior axis and the longitudinal axis, and a pair of longitudinal ribs on opposite sides of the median plane and posterior to the longitudinal axis, where a cranial-most connecting member connects each longitudinal rib to a first apex on the median plane anterior to the pair of longitudinal ribs and extends laterally and posteriorly in an unstressed configuration, and a caudal-most connecting member connects each longitudinal rib to a second apex on the median plane caudal to the first apex and anterior to the pair of longitudinal ribs and extends laterally and posteriorly in an unstressed configuration, and further having a third connecting member connecting the pair of longitudinal ribs to a third apex located on the median plane, anterior to the pair of longitudinal ribs between the second apex and the first apex, wherein the third connecting member is located between one caudal-most connecting member and the cranial-most connecting member.
Across clm-00001, clm-00017, and clm-00018, the inventive scope is defined by an implant architecture for retracting or/and supporting a prostatic urethra wall that specifies a longitudinally defined body with a longitudinal channel, a defined median plane and lateral axis, and a pair of longitudinal ribs connected to median-plane apices using cranial-most and caudal-most connecting members, with additional defining constraints based on anterior apex height (clm-00017) and inclusion/positioning of a third connecting member and third apex between caudal and cranial apices (clm-00018).
