Tissue engineered tendons and ligaments

Connective tissue, including neo-tendons and ligaments, has been constructed using biodegradable synthetic scaffolds seeded with tenocytes. The scaffolds are preferably formed from biodegradable fibers formed of a polymer such as polyglycolic acid-polylactic acid copolymers, and seeded with cells isolated from autologous tendon or ligament by means of enzymatic digestion or direct seeding into tissue culture dishes from explants. The cell polymer constructs are then surgically transplanted to replace missing segments of functioning tendon or ligament.

Method and Apparatus for Treatment of Congestive Heart Disease

In one aspect, the present invention is directed to an apparatus and method for treating congestive heart failure that restores kidney renal functions by artificial perfusion of at least one kidney. In one aspect, a catheter inserted into the aorta of the patient has an outlet port that supplies the patient's blood obtained from a patient's aorta into an adjoining renal artery of the patient to perfuse the kidney. The catheter comprises a rotor housed inside a portion of the catheter to supply the blood to the kidney at a desired pressure. The restoration of kidney function assists the heart by removing excess fluid, urine and toxin from the patient, and by normalizing the patient's renin-angiotensin system and other neurohormonal substances.

A catheter balloon and method involves extruded tubing with multiple layers of different durometer values, selected such that the blow up ratio (BUR) at the balloon's inner surface is increased. In one method a two stage blow mold process uses a small radius initial stage where radial growth is limited, followed by a second stage to a final dimension. A single stage blow mold process is also disclosed where the materials and processing are selected to approach the elongation to failure limit of the material. The single stage approach is preferably followed by a modified post-expansion heat set treatment to promote greater axial strength, leading to a preferred failure mode in the axial rather than radial direction.
