  • Patent number: 6605060
    Abstract: A delivery device for patient-controlled infusion of a medicament (6), the delivery device comprising a reservoir (2) for the medicament (6) and a pump (4) having a predetermined delivery dose which is capable of displacing the medicament from the reservoir (2) and delivering it to a patient, wherein the pump (4) comprises a pumping means (14), a first conduit (10), capable of restricting flow rate, chosen in conjunction with the delivery dose of the pumping means (14) to define a predetermined maximum dosage rate, said conduit (10) connecting the reservoir (2) to a pumping means (14), a one-way valve (18) in fluid communication with the first conduit (10) and the pumping means (14) which permits medicament flow into the pumping means (14) but prevents reverse flow, a controlling means (32), and a second conduit (28) extending from the pumping means and having a distal end (30) through which, the medicament may be released, wherein the controlling means (32), (a) is in fluid communication with the pumping mea

  • Patent number: 6468313
    Abstract: An implant material in the form of a natural animal tissue crosslinked into a pre-formed shape, the tissue being adapted to substantially retain its shape when implanted into a body. Suitable tissues include fibro-serous membranes such as pericardium. Suitable crosslinking agents include aldehydes (e.g., glutaraldehyde), epoxides, isocyanates, carbodiimides, isothiocyanates, glycidalethers, and acyl azides. The implant material can be processed in either the supple or non-supple form, by the judicious use of ethanol and/or other dehydrating solutions in the course of its processing.

  • Patent number: 6410044
    Abstract: A crosslinkable macromer system and related methods of preparing the system and using the system in the form of a crosslinked matrix between a tissue site and an implant article such as a tissue implant or on the porous surface of a prosthetic device. The macromer system includes two or more polymer-pendent polymerizable groups and one or more initiator groups (e.g., polymer-pendent initiator groups). The polymerizable groups and the initiator group(s), when polymer-pendent, can be pendent on the same or different polymeric backbones. The macromer system provides advantages over the use of polymerizable macromers and separate, low molecular weight initiators, including advantages with respect to such properties as nontoxicity, efficiency, and solubility. A macromer system of the invention can be used as an interface between the tissue site and implant article in a manner sufficient to permit tissue growth through the crosslinked matrix and between the tissue site and implant.

  • Patent number: 6328659
    Abstract: A golf ball dispensing and teeing device that is capable of automatically depositing a golf ball on a fixed tee or other desired location. The golf ball dispensing and teeing device has only one moving part and deposits the golf ball in an easy fashion without regard to whether the golfer is predominately left-handed or right-handed. The golf ball dispensing and teeing device includes a housing that is capable of storing a multiple of golf balls in a generally serpentine fashion as well as a guide assembly that transports a golf ball from the housing to the desired location.
