International Classification:

A61B 17/00
A61F 5/04

US Classification:

606 57

Abstract:

One aspect of the present invention is a connective tissue distraction device comprising: a first transmitting structure for transmitting force to a first tissue region and a second transmitting structure for transmitting force to a second tissue region by contact with bone, and an expansion device for exerting force distracting the first transmitting structure from the second transmitting structure. At least one of the first transmitting device, the second transmitting device and the expansion structure comprises in whole or in part a biodegradable, bioerodible or bioresorbable material.

International Classification:

A61B017/58

US Classification:

606/090000

Abstract:

The present invention recognizes that existing distraction devices have certain disadvantages, including the requirement to remove materials in the distraction device from the subjects body after distraction is completed. Depending on the location of distraction, this procedure can be of varying degrees of undesireability. One aspect of the present invention is a connective tissue distraction device comprising: a first transmitting means for transmitting force to a first tissue region and a second transmitting means for transmitting force to a second tissue region by contact with bone, expansion means for exerting force distracting said first transmitting means from said second transmitting means, wherein at least one of said first transmitting means, said second transmitting means and said expansion means comprises in whole or in part a biodegradable, bioerodible or bioresorbable material.

International Classification:

A61F002/06

US Classification:

623001220

Abstract:

A stent is described that is configured to be inserted into a lumen of a patient. The stent includes a coiled body in a generally helical configuration. In certain aspects, the coiled body includes a strip of multiple strands coupled together. In other aspects, the coiled body includes a strip having one or more lumens in the strip. In addition, certain stents have a coiled body formed by a strip of multiple strands in which at least one of the strands includes a lumen. Pharmaceutical or therapeutic agents may be provided in the lumen to provide a therapeutic effect to a patient receiving the stent. Markers may also be provided in the lumen to facilitate placement of the stent in a patient.

International Classification:

A61B 17/80

US Classification:

606 71

Abstract:

A device for early stabilizing of distracted tissue that includes a first implant, a second implant, a sliding expansion mechanism and a stabilizer. The first implant is capable of being attached to a first tissue region. The second implant is capable of being attached to a second tissue region. The sliding expansion mechanism engages the first implant and the second implant for distracting the first implant away from the second implant to create a distraction space for formation of the distracted tissue. The stabilizer rigidly fixes the first implant and the second implant after disengagement of the sliding expansion mechanism to rigidly stabilize the distracted tissue. The stabilizer includes in whole or in part a biodegradable, bioerodible or bioresorbable material.

A61M 5/142
A61B 18/14

Abstract:

A medical instrument is disclosed that includes an elongated probe section having a length (L) between a proximal and a distal probe section end. The probe section includes a plurality of carbon fibers that is arrayed along the axis and embedded in a medical grade, biocompatible epoxy resin. The probe section is constructed to be rigid by controlling the density of carbon fibers such that the maximum predetermined off-axis deflection (d) is less than about 30% of the probe section length (d

International Classification:

A61B 17/80

US Classification:

606 71

Abstract:

A method for early stabilizing of distracted connective tissue. A distraction site is at least partially covered with biodegradable, bioerodible or bioresorbable materials before a distraction procedure takes place. Distraction is performed on a connective tissue at the distraction site. The distracted connective tissue is stabilized using the biodegradable, bioerodible or bioresorbable materials.
