A device for delivering a substance such as a surgical sealant or adhesive to an internal portion of the body that has been acted on by a procedure performing instrument such as a catheter, trocar, laparoscopic instrument or a biopsy device is described. The invention more particularly relates to a biopsy device for obtaining one or more tissue samples and for applying at least one substance to the biopsy site in one operation.

Substance delivery device for use with a procedure performing instrument

A unique powder-free medical glove fabricated from a neoprene copolymer, and a method of making same is described. The gloves of the invention are easily donned without the use of powdered donning agents and retain their puncture resistance, tensile strength, stress at 500% and elongation to break after post-processing by chlorination and sterilization by irradiation. Additionally, the gloves of the invention exhibit minimal discoloration (as measured by the per cent change in yellowness index) and minimal stickiness to themselves and to glove packing materials after sterilization by irradiation.

Powder free neoprene surgical gloves

A thin elastomeric glove with enhanced gripping surfaces molded into the gripping surfaces of the glove is described. Preferably, the enhanced gripping surface is molded into each of the finger and thumb tips and body portions of the gloves. The enhanced gripping surface may be comprised of a plurality of concave indentations molded into the gripping surfaces of the glove. Alternatively, the enhanced gripping surface is comprised of a plurality of suction cups molded into the gripping surfaces of the glove. The glove may be constructed of any natural or synthetic rubber latex or blends or combinations thereof and has a thickness between about 0.004 to about 0.012 inches, an elongation greater than about 200%, a tensile strength between about 1500 to about 5000 psi and a 500% modulus between about 300 to about 2000 psi.

A system for percutaneous transluminal front-end delivery and retrieval of a collapsible prosthetic occluder includes a front-end loading portion, a control assembly and an introducer and retrieval sheath assembly. The front-end loading portion includes a tapering lumen portion and a smaller diameter distal lumen portion. An infusion port communicates with the distal lumen portion immediately adjacent the distal end of the tapering lumen portion. A valve assembly seals the front-end loading portion lumen proximally of the collapsed occluder. The distal end of the front-end loading portion lumen is inserted into the proximal end of an introducer and retrieval sheath assembly. A control assembly advances the occluder through the front-end loading portion, the introducer and retrieval sheath assembly and into the defect site. The retrieval sheath assembly is less flexible than the introducer sheath and is sufficiently rigid to evert the deployed occluder when retracted thereagainst.

A method for percutaneous transluminal front-end delivery of a collapsible prosthetic occluder using a front-end loading portion, a control assembly and an introducer sheath. The prosthetic device is collapsed in a lumen of a front-end loading portion. A valve assembly seals the front-end loading portion lumen proximally of the collapsed occluder. Fluid is then infused through a port extending into the front-end loading portion in communication with the front-end loading portion lumen to remove air bubbles from the collapsed prosthetic device. The prosthetic device is advanced using a control assembly from the front-end loading portion into the introducer and ultimately into the defect site.
