US Patent:

59470623, Sep 7, 1999

Filed:

Mar 4, 1998

Appl. No.:

9/034725

Inventors:

Michael C. Hoffman - Royal Oak MI
E. Eric Hoffman - Livermore CA

International Classification:

A01K 2700

US Classification:

119769

Abstract:

A restraint system which can remain on an animal at all times. In one embodiment, the restraint system includes a strap which serves as both a collar and a leash. The restraint system can be in either an extended state or a retracted state. In the extended state, the collar portion is positioned around the animal's neck and the leash portion extends from the collar portion to the animal owner's hand. In the retracted state, the entire restraint system is stored around the animal's neck by reversibly attaching the leash portion to the collar portion, as well as to the leash portion itself, in an overlapping spiral configuration. VELCRO. TM. strips can be used to reversibly attach the leash and collar portions. Another embodiment of the invention includes a restraint system which includes a collar assembly coupled to a leash assembly. The collar assembly and the leash assembly are made from separate straps and are attached to each other by a connecting element.

International Classification:

A61B 90/00

Abstract:

A prosthetic implant, such as a tissue expander, includes a silicone shell having an anterior wall and a posterior wall, and a needle stop patch secured over an inner surface of the posterior wall of the silicone shell. The needle stop patch has two or more layers of a textile material that are stacked atop one another. The textile material is flexible and includes woven threads or fiber. A bonding material bonds together the two or more layers of the textile material that are stacked atop one another. The outer edges of the respective layers are feathered for minimizing step effects between adjacent ones of the layers. A self-sealing membrane covers the anterior wall of the silicone shell. The dernier level of the textile layers increases between top and bottom layers for progressively increasing resistance tom a needle passing through the needle stop patch.

International Classification:

A61B 17/06

Abstract:

A wound closure assembly includes an insertion tool having a proximal end and a distal section, such as a curved distal section, having a penetrating tip and first and second notches that are formed on opposite sides of the distal section. The assembly includes a tissue anchor having a hollow body and an insertion tool channel extending through the hollow body. First and second spaced tips project distally from the distal end of the hollow body and oppose one another on opposite sides of the insertion tool channel. The distal section of the insertion tool is inserted into the insertion tool channel of the tissue anchor so that the penetrating tip is distal to the first and second spaced tips, with the first and second spaced tips nested within the first and second notches for generating a releasable interference fit between the tissue anchor and the insertion tool.
