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 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. A pair of cranial projections is configured to rest on a ledge of a bladder neck to prevent cranial drift of the implant into a bladder.
The implant further includes a pair of posterolateral retractors located on opposite sides of the median plane and posterior to the longitudinal axis. At least one cranial interconnecting member connects a cranial portion of each posterolateral retractor to a cranial anterior apex located on the median plane, and at least one caudal interconnecting member connects a point caudal to the cranial interconnecting member on each posterolateral retractor to a caudal anterior apex located on the median plane. In an unstressed configuration, the cranial and caudal interconnecting members extend laterally and posteriorly from the anterior apices to the posterolateral retractors.
In set form, the invention defines a set of implants for a prostatic urethra including a large implant and a small implant proportionally similar within 10% to the large implant. The large implant has an elongated implant body with a longitudinal axis extending between a cranial end and a caudal end along a median plane dividing the implant body into two symmetrical halves, and the set retains the pair of posterolateral retractors and the cranial and caudal interconnecting members extending laterally and posteriorly in an unstressed configuration.
Claims Coverage
This consolidated document contains two independent claims: one directed to a single implant structure for retracting or supporting a prostatic urethra wall, and one directed to a set of implants including large and small implants with proportional similarity. Across these independent claims, the main inventive features are the bladder-neck-ledge cranial projections, the median-plane geometry, the posterolateral retractors, and the cranial and caudal interconnecting members extending laterally and posteriorly in an unstressed configuration, including proportional set sizing constraints.
Bladder-neck-ledge cranial projections to prevent cranial drift
A pair of cranial projections configured to rest on a ledge of a bladder neck thereby preventing cranial drift of the implant into a bladder.
Median plane and lateral crossing of the channel on a posterior portion
A median plane including said longitudinal axis and perpendicular to a line connecting said cranial projections, wherein said line between said pair of cranial projections crosses said channel laterally on a posterior portion thereof posterior to said longitudinal axis.
Posterolateral retractors on opposite sides of the median plane
A pair of posterolateral retractors located on opposite sides of said median plane and posterior to said axis.
Cranial interconnecting members extending laterally and posteriorly in an unstressed configuration
At least one cranial interconnecting member connecting a cranial portion of each of said pair of posterolateral retractors to a cranial anterior apex located on said median plane anterior to said pair of posterolateral retractors, wherein in an unstressed configuration said at least one cranial interconnecting member extends laterally and posteriorly from said cranial anterior apex to each of said posterolateral retractors.
Caudal interconnecting members extending laterally and posteriorly in an unstressed configuration
At least one caudal interconnecting member connecting a point caudal to said cranial interconnecting member on each of said pair of posterolateral retractors to a caudal anterior apex located on said median plane caudal to said cranial anterior apex and anterior to said pair of posterolateral retractors, wherein in an unstressed configuration said at least one caudal interconnecting member extends laterally and posteriorly from said caudal anterior apex to each of said posterolateral retractors.
Set of implants with large and small proportionally similar within 10%
A set of implants for a prostatic urethra comprising a large implant and a small implant proportionally similar within 10% to said large implant.
Median-plane symmetry dividing the implant body into two symmetrical halves
The large implant having an elongated implant body having a longitudinal axis extending between a cranial end and a caudal end of said implant body along a median plane dividing said implant body into two symmetrical halves.
The claim scope in the provided content centers on a prostatic urethra implant and a proportional set defined by cranial projections resting on a bladder-neck ledge to prevent cranial drift, a median-plane/symmetry framework, a pair of posterolateral retractors, and cranial and caudal interconnecting members that extend laterally and posteriorly from median-plane apices in an unstressed configuration.
Stated Advantages
Prevents cranial drift of the implant into a bladder.
