A flexor tendon repair device has a sheet of mesh material of rectangular shape with four edges: two longitudinal edges and two lateral edges perpendicular to the longitudinal edges. Each pair of edges is mutually parallel and spaced apart. Each edge is also folded inwardly for two smooth edges upon which the healing tendon rests and two smooth edges where the sheet mutually joins. Along with the sheet, the invention includes sutures, typically doubled, and one at each lateral edge. The lateral edges generally support the healing tendon while the sheet wraps around the tendon with the longitudinal edges generally parallel to the length of the tendon. A surgeon, during use of the invention, tightens each suture along the longitudinal edges, closing the device, and then upon the laterals to tie the suture. Upon tying, the mesh attains an ovoid shape similar to the natural cross section of a tendon.

A probe apparatus for self-administered treatment of prostatitis has a pair of opposing handle bars symmetrical to each other having handle grip ends and connected to a center housing along a common axis, and a probe connected to a front side of the center housing and extending to a probe tip. The center housing has a vibrator motor which is mechanically coupled to the probe tip, and is actuated by a switch on one of the handle grip ends. The probe has a swivelable tip actuated by a pair of swivel actuators provided on the handle grip ends. The probe tip has an off-center bulbous or ovoid shape for effecting a sweeping movement over the prostate when a swivel actuator is actuated. The probe and the handle grip ends have approximately the same length and extend in the same direction for more precise manipulation by the patient. The handle bars are connected to the center housing by twist-lock disconnectors to be detachable for storage or packing. The probe apparatus is employed by inserting the probe into the rectum from the rear of the patient, and positioning the probe tip adjacent the colon walls proximate the prostate while manipulating the handle grip ends on each side of the patient. It is employed with the patient in a standing, bent over position, and a mirror is placed on the floor between the patient's feet to provide visual confirmation of the position of the probe. The probe apparatus is effective for prostatitic drainage by manipulating the swivel actuators to sweep over the surface areas of the prostate toward the prostate center in order to drain fluid from the prostate gland and ducts.
