Described are devices and methods for forming a surgical space within a body of a patient by blunt dissection, including devices that include a blunt dissection device and optionally one or more of an insufflation lumen, access lumen, and viewing device.


Patent
AMS Corporation | Date: 2016-07-20

The invention provides an insertion tool comprising a handle, a needle extending from the handle, the needle comprising a shaft comprising a proximal end attached to the handle and a distal end that includes a needle tip configured to engage a self-fixating tip, and at least one extension guard extending laterally from the needle on a proximal side of the needle tip.


Patent
AMS Corporation | Date: 2016-03-23

An apparatus for placement in a patient, comprising: an electronic device; a pressure-transducing substance; and a hollow casing, comprising a wall, a portion of which wall defines one or more holes therethrough, inside which casing the electronic device and the pressure-transducing substance are disposed, the casing being configured to facilitate flow of some of the pressure-transducing substance out of the one or more holes when the casing is being filled with the pressure-transducing substance.


Patent
AMS Corporation | Date: 2016-01-20

The invention provides an implantable electrode lead for facilitating electrical stimulation of tissue of a patient, the electrode lead comprising a lead body having a distal end; an electrode attached to the distal end of the lead body, the electrode comprising a plurality of stimulation elements formed of an electrically conductive material; and at least one insulative element formed of an electrically non-conductive material; wherein the stimulation elements and the at least one insulative element are joined together to form a stacked column of alternating stimulation and insulative elements; a plurality of electrically conductive wires extending through the lead body, each wire coupled to one of the stimulation elements; and a tissue anchor configured to facilitate anchoring the electrode to tissue of the patient, wherein each of the stimulation elements comprises a body having first and second ends; and each of the at least one insulative elements comprises a body having first and second ends that are respectively configured to interconnect with the second and first ends of the body of one of the stimulation elements.


Patent
AMS Corporation | Date: 2016-10-05

The invention provides a pelvic implant useful to treat a condition of urinary incontinence, the implant comprising a tissue support portion, a first extension portion, a first adjusting mechanism comprising a first line extending between the tissue support portion and the first extension portion, the first line being capable of being tightened to adjust a distance between the first extension portion and the tissue support portion, a first line holder that engages the first line and is capable of maintaining an adjusted distance between the first extension portion and the tissue support portion, and a first tether, and a self-fixating tip at a distal end of the first extension portion, wherein pulling the first tether in a proximal direction causes the distance between the first extension portion and the support portion to be reduced.


Patent
AMS Corporation | Date: 2016-11-16

A system for ligating a uterine artery in a patient generally includes a suture transfer tool (40), suture transfer darts (60, 61), and one or more sutures (62, 64). The suture transfer tool includes an upper jaw (42) that is pivotally joined to a lower jaw (46). The lower jaw of the tool includes a number of suture capturing pins (54). The suture transfer darts are configured to be tissue piercing and are positionable within the suture capturing pins. Each end of the suture is connected to a suture transfer dart. When operating the tool, the suture transfer darts pierce through the tissue to either side of a patients cardinal ligament, which contains the uterine artery, and simultaneously present an end of the suture to either side of the cardinal ligament. As such, the suture is in an open loop configuration about the cardinal ligament and can be tied tight to the ligament to occlude the uterine artery.


Patent
AMS Corporation | Date: 2016-08-24

A needleless injector comprising: a body comprising a fluid chamber; an outer shaft extending from an outer shaft proximal end at the body to an outer shaft distal end, the outer shaft comprising an outer shaft lumen between the outer shaft proximal end and the outer shaft distal end, to accommodate an injection shaft; an injection shaft located within the outer shaft lumen and moveable lengthwise, rotationally, or lengthwise and rotationally, within the outer shaft lumen, the injection shaft comprising an injection shaft proximal end, an injection shaft distal end, an injection shaft terminus, and an injection lumen extending between the injection shaft proximal end and the injection shaft distal end, an injection orifice at the distal end of the injection shaft and in fluid communication with the fluid chamber through the injection lumen, the injection orifice being located on a proximal side of the injection shaft terminus and being directed away from the longitudinal axis of the injection shaft at the location of the injection orifice; a pressure source in communication with the fluid chamber, the pressure source being capable of pressurizing fluid within the fluid chamber to an injection pressure capable of causing fluid ejected from the injection orifice to penetrate into tissue; and an optical device that allows viewing a location at a distal end of the device.


Patent
AMS Corporation | Date: 2015-10-08

An implantable electrical stimulation device configured to treat multiple pelvic conditions of a patient includes a pulse generator, memory, first and second electrode leads comprising one or more electrodes, a switch and a controller. The switch has a first state, in which the first electrode lead is electrically coupled to the pulse generator, and a second state, in which the second electrode lead is electrically coupled to the pulse generator. The controller includes at least one processor that is configured to execute at least one stimulation program stored in the memory. The controller is also configured to selectively set the switch in the first or second state. Electrical stimulation pulses generated by the pulse generator responsive to the execution of the stimulation program are delivered to the first or second electrode lead depending on the state of the switch.
