An self-actuating grasping device and corresponding method of using the grasping device for retrieving a foreign object from a location in a patient's body. The grasping device has a handle with a self-actuating mechanism, an actuator on the handle coupled to an actuator wire, an elongated shaft member extending distally from the handle with the actuation wire coaxially disposed therein and opposing jaws at a distal end of the elongated shaft member that are coupled to the actuation wire and pivot between open and closed configurations. The self-actuating mechanism has a bias that imparts a closing force to the opposing jaws through the actuation wire. Actuation of the actuator is configured to impart an opening force to the opposing jaws through the actuation wire.

Self-actuating grasping device

Devices and methods are disclosed for managing and/or treating body tissues obstructing a hollow body lumen, including the prostatic lobe tissues obstructing the urethra, for example conditions including benign prostatic hyperplasia (BPH), bladder outlet obstruction (BOO), benign prostatic obstruction (BPO) and associated lower urinary tract symptoms (LUTS). A retrieval sheath having an elongated shaft member with at least one region of modified flexibility that is configured compress the implant to a reduced profile for removal from the patient's body.

Devices for the treatment of benign prostatic hyperplasia and related lower urinary tract symptoms

The invention is devices and methods to treat benign prostatic hyperplasia (BPH) and associated lower urinary tract symptoms infections (LUTS). The devices are intra-urethral implants placed in a patient in need thereof by minimally invasive procedures, preferably under local anesthesia in an office environment. The devices are sized and designed for atraumatic insertion and expansion within the urethra to engage and retract enlarged prostatic tissue proximate to the urethra that is leading to adverse symptoms associated with BPH. The methods include steps to deploy the implant devices of the invention using a delivery system of the invention and at target prostatic tissue that is visualized during the procedure and yields a reduction in the symptoms of BPH.
