摘要:
A biodegradable balloon adapted to exert pressure on a hole formed in a lumen in the body when placed adjacent to the hole, inside the body, and expanded, and adapted to remain in place thereafter and to be absorbed by the body.
摘要:
Stents which are inserted into a body lumen preferably are made of materials which are not radiopaque enough, such as stainless steel 316L. X-ray visualization of a stent enables an accurate positioning of the stent and also a follow-up of its functioning within the patient's body. The radiopaque markers described here are rivets made of a material which is more radiopaque than the stent substance so the location of the stent can be identified. Preferably the stents are heat treated so that atoms from the stent material migrate into the marker material and vice versa.
摘要:
A method of regulating a setting time of a bone filler material, the method comprising: (a) combining at least two filler material components to form a biocompatible mixture; (b) choosing a setting time for the mixture; and (c) regulating a temperature of the mixture to influence reaction kinetics so that the mixture does not set before the chosen setting time.
摘要:
A method of long bone strengthening and a composite implant for such strengthening. Also disclosed is a kit for building a composite implant in-situ in long bones. In an exemplary embodiment of the invention, the implant comprises a plurality of rigid tensile rods, in matrix of cement and surrounded by a partially porous bag.
摘要:
A method of treating a vertebra, comprising: (a) accessing an interior of a vertebra; and (b) introducing a sufficient amount of artificial biocompatible material which does not set to a hardened condition in storage, into said bone, with sufficient force to move apart fractured portions of said bone.
摘要:
Methods, systems, and mixtures deliver a bone cement to a void in a bone, and provide an expandable filler for expanding the volume of the bone cement. The void in the bone is accessed and a bone cement material is introduced into the void in the bone. An expandable filler is introduced into the void in the bone. The introduction of the filler can take place simultaneously with the introduction of the bone cement or before or after the bone cement. The expandable filler can be expanded and the bone cement can be allowed to set.
摘要:
A bone cement comprising a first component and a second component, wherein contacting the first component and the second component produces a mixture which attains a high viscosity an initial period and the viscosity of the mixture remains relatively stable for a working time of at least 5 minutes after the initial setting period, and the mixture is suitable for in-vivo use.
摘要:
A bone boring device and method, the device comprising a hinge, a handle coupled to the hinge, and at least one curved needle with a tip. The needle is rotatably mounted on the hinge such that when the tip is placed against bone and the needle is rotated on the hinge, the needle is urged and advanced into the bone. Preferably, the at least one needle is a first and a second needle. Alternatively, the needles may rotate about the same hinge or different hinges.
摘要:
The present invention relates to apparatus and methods for treatment of male incontinence and a method for female cystocele repair in which a sling material is positioned between the descending rami of the pubic bone. In such an operation a “hammock-like” sling material is positioned below the urethra in males, or below the posterior bladder wall in the case of cystocele in females.
摘要:
A surgical tack, comprising: a single shaft formed of a bio-compatible material and having a tip adapted for entering and engaging bone; and a head mounted on said shaft, said head adapted for engaging a substrate between said head and said bone. Preferably, said shaft is a separate element from said head. Alternatively or additionally, said head is rotatable relative to said shaft.
