An implantable device for the treatment of acid reflux disease has a body including an outer surface adapted to rest against a patient's fundus wall. The device, when implanted in a patient, fills a volume in the patient's abdomen in the cardia area and above the cardia of the patient, when standing. The body prevents the cardia from moving through the diaphragm opening into the thorax, thereby preventing reflux by keeping the abdominal pressure supporting the cardia sphincter muscle. The device may be affixed to stomach tissue. The device may also be invaginated or otherwise indirectly secured in position.

An apparatus for monitoring the intra-abdominal pressure of a patient includes a urinary catheter (102) connected to a urine valve (250) providing selectable communication between a discharge end of the urinary catheter (102) and either a drain (224) or a fluid source (104). Preferably, the urine valve (250) is adapted for remote actuation and has a housing adapted to resist patient discomfort from leg-valve (250) contact. Plumbing structure desirably maintains fluid supply (225) and drain (223) conduits in a substantially parallel arrangement to assist routing those conduits (225, 223) between a patient's legs. When the urine valve (250) is oriented to permit communication with the fluid source (104), an infusion pump (116′) may be used to infuse a known quantity of fluid through the urine valve (250) and into the patient's bladder (216). A pressure transducer (218) desirably is connected in-circuit to indicate the fluid's pressure and avoid pressure fluctuations induced by system components. To facilitate the infusion process, an automatic flow control device may be included in a fluid supply path (225) and arranged to permit repetitive operation of a syringe (116′) to inject a bolus of fluid into the patient's bladder (216). Subsequent to making a pressure measurement, the urine valve (250) is returned to the bladder (216) draining position.

An implantable urodynamic system includes an implantable first device deployable in a patient's bladder, an implantable second device deployable in a patient's vaginal canal, and a data acquisition and analysis module or processing unit external to the body of the patient.

A Diastasis Recti Splinting Garment is described which includes a plurality of attached torso straps and pelvic straps which the user wraps around their body and connects to the garment so as to approximate the 2 sides of the abdominal wall, providing support to the linea alba and fascial sheathes to allow for tissue healing. Furthermore, the adjustable angled straps encircle the torso and pelvis of the user to restore the integrity of the core, providing stability to the ribcage, spine and pelvis. Restoring the integrity of the core lends itself to optimal activation of the deep core stabilizers, including the abdominal muscles as well as the musculature of the pelvic floor, back, and diaphragm. This in turn aids in dynamic stability of the spine, ribcage and pelvis. This allows maximum support of the diastasis recti, consequently facilitating tissue healing through balancing intra-abdominal pressure, while still supplying support to the vulnerable pelvic floor and stability to the spine, ribcage and sacroiliac joints.
