Surgical Suture Patent
 

Absorbable surgical suture material based on monocarboxycellulose and method for producing the same

An absorbable surgical suture material based on monocarboxycellulose having the general formula ##STR1## where: m is a degree of polymerization of the initial cellulose from 250 to 3300; p is a molar fraction of D-glucopyranose cycles in one polymer period from 0.95 to 0.05; q is a molar fraction of cycles of d-anhydroglucuronic acid from 0.05 to 0.95; S is a molar fraction of the complex fragment of D-anhydroglucuronic acid, metal, and ligand from 0.03 to 0.55; Me is a transition metal; n is a valence of the transition metal; k is a coordination number of the transition metal .gtoreq.4; Lig is polydentate ligands; Dent is a dentation of the ligands .gtoreq.2. A method for producing said material consists in that cellulose threads are first threaded with nitrogen oxides, then for 0.5 to 2.0 hours treated with a 0.5-2.0-percent solution of a salt of a transition metal with a coordination number not less than 4 in a suitable solvent, and after this treated for 0.5 to 2.0 hours with a 1.0-2.0-percent solution of a polydentate complexing agent in a suitable solvent.

Surgical suture holding device

A device for holding a surgical suture including a base, a guide body, a cam body, a bearing member, and a spring member. The base has a top side, a front edge, and a back edge. The guide body projects from the top side of the base and defines a guide face having an entrance side and an exit side. The entrance side is adjacent the front edge and the exit side is adjacent the back edge. The cam body is pivotally mounted to the top side and forms a toothed surface positioned to selectively secure a surgical suture against the guide face. The spring member is positioned between the cam body and the bearing member, biasing the toothed surface toward the guide face.

Surgical suture placement device

The invention provides a surgical suture placement device that includes a handle assembly rotatably secured to an elongated hollow outer tube extending from the handle assembly. Also included is a suturing assembly rotatably secured to the distal end of the elongated hollow outer tube and a hollow flexible tube connecting the handle assembly to the suture assembly by traversing the inside of the elongated hollow outer tube. The device can be used for placing a suture through the urethra and bladder neck to perform an urethrovesical anastomosis, e.g., after removal of the prostate.

Bioactive surgical suture

The application concerns surgical suture coated with one or more biologically active compounds. The application discloses methods of making coated suture, placing the coated suture in an organism, and methods of using the coated suture in the treatment of diseases such as cancer.
