Biopsy sampler
First Claim
1. An assembly for performing a medical procedure, comprising:
- an endoscopically deployed medical device for tissue-plasty, and a sheath exterior to said medical device and sized to be present within the body with said medical device, wherein said sheath and medical device are constructed as a unitary device, and wherein said medical device extends distally of the termination of said sheath, said sheath including an electrode element electrically isolated from said medical device, spaced proximally to said medical device, and disposed on said sheath'"'"'s outer surface for cauterizing tissue, said medical device and sheath cooperatively constructed to permit sequential tissue-plasty and cauterization of tissue.

Abstract
The invention features an assembly for taking a biopsy sample from a site within the body of a patient. The assembly includes a resecting device having a cutter near its distal end for resecting and containing a tissue sample and a sheath exterior to the resecting device and sized to be present within the body with the resecting device. The sheath includes an electrode element electrically isolated from the resecting device and disposed on the sheath'"'"'s outer surface for cauterizing tissue. The electrode element may reside on the outer sheath, the distal end or both the outer sheath and the distal end of the assembly. The resecting device and the sheath cooperate to permit sequential resecting of a tissue sample from a resecting site and cauterizing of the site with the cutter sufficiently spaced from the electrode element to avoid heat damage to the tissue sample.
